The Grading of API Steel Pipe

  In general, API steel pipe can be graded on the basis of ASTM (American Society for Testing Materials) standards and ASME standards. ASTM is a prestigious global organization that has been devoted to the development of industry standards. ASME standards roughly cover a wide range of materials that are manufactured and used in construction projects or various industries. ASTM is a voluntary standards development company is wholly independent of any manufacturers. As a matter of fact, ASTM International is the company that issues the industry standards for most of the steel pipe manufacturers. ASME standards of API steel pipe can be either downloaded or purchased from ASTM website and several other websites that host the documentation of ASME standards.

There are a vast number of steel pipes produced in the piping industry. For example, some of the commonly seen steel pipes are API steel pipe, seamless steel pipe, welded steel pipe, and black steel pipe. What is more, there are a lot of subcategories for each type of steel pipe. For instance under the category of welded steel pipe, there are ERW welded steel pipe, single welded pipe, continuously welded pipes, etc. And while some low carbon steel pipes can be used in the oil and gas industries some other pipes cannot. Therefore, ASME standards of each steel pipe are based on its specific manufacturing process, raw materials and production techniques. The manufacture and installation of API steel pipe is tightly regulated by the ASME standards. In fact, ASME standards have the force of law in such countries as Canada and the USA and are also recognized in many European countries and African nations. To ensure the high quality of the piping products, the manufacture, storage, testing, etc. of API steel pipe must meet stringent quality ASME standards. What is more, manufacturing standards for API steel pipe commonly require a test of chemical composition and a series of mechanical strength tests.

Pressure and wall thickness are among the major criteria in grading API steel pipe. In general, API steel pipe is graded is strength in terms of pressure and there are many grades of API steel pipe for each standard ASTM Code. The code refers to a minimum yield strength and minimum tensile strength of API steel pipe and there are grades ranging from grade 1, grade 2, grade A, grade B, to grade X. Each grade of API steel pipe has a minimum and maximum pressure rating.

No matter what type and size of the pipes, ways to clean it should be utilized to work best for you and your demands. So, remember the following steps.

If you want to clean it inside to keep the quality of the inner fluid, you need to run water through the inside of the pipe. This is important to remove the normal dirt inside. We know that the pipe has different sizes, so different ways are used. If the pipe is in small size, it can be done in a sink. However, when it is large enough, you should use a water hose outside to fit in the sink.

You need to tilt and twist the pipe after the pipe is sunk. To make the water runs against the inside of the pipe, you are told to tilt it when the water is running. This is an important step to clean and washing out the dirt. Then twist the pipe so the water cleans off the sides of the pipe. Next step is to use a scrub brush saturated with soapy water to scrub the inside of the pipe. If the pipe is too narrow to fit your hand though, use a baby bottle brush to clean the inside. And the last step is to rinse the pipe with clean water and allow it to dry.

Commonly, to clean black steel pipe, welded steel pipe or API steel pipe, the above ways are all suitable. Actually, no matter it is inside or outside, ways to clean are all important.

Four Development Stages of Welded Steel Pipe

  Steel pipe has wide application and welded steel pipe is one of the popular steel pipe among users. It is available in wide range of sizes and properties of the steel. Now, it is easy to cold form flexible pipe from coils of sheet steel with automated spiral welds. When it comes to issues of steel pipe, we can't help talking about its quality control, testing, joints and protective surface painting actually. Compared with other steel pipes, welded steel pipe is strong, easy to install and it also has high flow capacity, leak resistance. If you are searching for steel pipe with long servicelife, reliability, and versatility and low cost, you surely should pay attention to the welded steel pipe actually.

Since 1916, welded steel pipe has been used for transporting water, food, petroleum and chemical materials. There are countless manufacturers of welded steel pipe both at home and abroad. Do you know that, the use of pipe has a long long history. Pipes used for water supply began around 2500 B.C. Since then, the Chinese transported water through bamboo. And in Southern Europe and Near East, the tile pipes were used to supply water for the baths of kings and emperors. Well, the iron age began about 1000 BC. Although no classical historians spend theirm time investigating pipes, a lot of information have been saved, one of which is the History of Steel Water Pipe by Walter H. Cates.

There are mainly 4 stages of the being of the welded steel pipe:

Stage 1 United States built the first furnace in 1830 to make wrought iron pipe. And pipe had been used practically since 1858, when steel sheets were shipped to San Francisco for building needs. However, the production of the steel pipe was limited since iron was not as sufficient as now caused by undeveloped technology and small requirements. And the pipes were in small diameters and few sizes.

Stage 2 Here came the steel age in 1855. Sir Henry Bessemer patented a process for production of steel in England. With the development of steel, especially the development of the open hearth furnace in 1861, inexpensive steel in large quantities seemed possible. Steel made it possible for forming sheets into pipes of different diameter.

Stage 3 Lock-bar steel pipe in 30-foot lengths can be regarded as another milestone of welded steel pipe. The two semi-circular pipe halves were joined by inserting the edges of each into two longitudinal lock-bars with an H-shaped cross section.

Stage 4 Automatic electric welding also contributes to the development of welded steel pipe. Although electric welding was still new or strange in 1920, it had made great progress during 1930s. The development of welding machines and fluxes also contributed to the development of welded steel pipe actually.

The black steel pipe and API steel pipe are also available.

The Best Uses for a Pipe Reducer

It is able to connect pipes of different diameters. In order to better transport oil, natural gas and other fluid by welded steel pipe, pipe reducer made a great contribution. The use of the reducers will be benefit for fluid transportation and daily life and production, but because of its wide range, therefore, it is very necessary to choose the right type of reducer under the right conditions, it can make the reducer's advantages greater extent.

In order to improve the performance of the suction pump, pipeline pump suction line should be as short as possible, minimizing the bend (elbow preferably with a large radius of curvature), so that reduce pipe resistance losses. To prevent pump cavitation, pump suction line should be possible to avoid the accumulation of gas in the capsule -shaped parts, if the accumulation cannot be avoided. DN15 or DN20 vent valve should be set in the bag-shaped parts. When the pump suction pipe is the vertical direction, eccentric reducer should be configured on the suction pipe to avoid formation of air pockets if it is necessary. In order to avoid force and torque brought by the weight of weld steel pipes and valves and piping thermal stress generated by the pump exceeds the maximum allowable export external loads on the pump.

We must provided pipe rack on pump's suction and discharge piping. Pump nozzle allows the maximum load provided by the pump manufacturer. If the import or export of pump is vertical, the nozzle shall be located above the line pipe rack in order to reduce the force of the pump nozzle. Its flat position should be as close as possible to the nozzle, you can use the pipe rack stringers hanging branch pipeline, so the pumps are always arranged in a tube porch. If the liquid conveying density is less than 650Kg/m3,such as: liquefied petroleum gas, ammonia , etc. It is better to equipped with a straight weld steel pipe which diameter is approximately 3 times as import on the inlet of the single-suction pump.

As to double suction pump, double suction pipe of pump should be arranged symmetrically on both sides to ensure uniform flow distribution in order to avoid a two-way suction centrifugal pump cavitation level. Vertical pipes connected by a vertical pipe elbow directly, but the pump must be perpendicular to the plane of the axis of the elbow is located. In this case, the import piping should be as short as possible, then using elbow to connect the pipe reducer, followed by inlet flange. Under other conditions, there is necessary to equip a straight pipe not less than three times the diameter before the pump inlet. We can use a vent valve to put the liquid out between outlet shut-off valve and check valve of the pump. When the diameter is larger than DN50, you can also put a vent valve by opening a hole in the cover of check valves. the inlet and outlet valves specifications of the pump should adopt the same standards. The black steel pipe and API steel pipe are also available.

How to Weld a Steel Pipe and clean its Resin

  Welding API steel pipe varies greatly depending on the style and type of steel. According to the delta school of trades, certain API steel pipe require special preheating and cooling to ensure cracking does not occur during welding or cool down. Most welders use TIG or MIG welding tools. You should know that on-line welding source muggy welds that making use of a common hand-used propane torch for metal welding. Welding rods and soldiers, elements employed to connection throughout welding, melt at differing temperatures and element styles for a range of metal welding work.

Use API steel pipe 1. Make positive welding goggles include your eye balls throughout the melting procedure to safeguard them from vibrant mild. 2. Heat the metal pipe ends to be welded. Melt the welding rod into the joint of the metal pipe. 3. Or soldier the welding rod into the joint of the metal pipe making use of a propane torch. 4. Make positive the melted welding rod or soldier joint includes the whole surface area of the pipe joint. 5. Permit the welded joint and metal pipe to awesome. 6. Analyze the potency of the joint by applying stress to the pipe close to the weld.

Use API steel pipe are one of several varieties of pipes created to smoke tobacco in all tobaccos have numerous aromas and all numerous varieties of resins. Resin is the gooey tar-like substance left in the pipe soon after cigarette smoking a bowl of tobacco. It can differ in color from dark to brown, and when it hardens on the surface area, it can be tough to get rid of. You'll require some fundamental residence elements to clean up the resin out of your metal pipe, and you might require buying some points, but all in all, it is not incredibly pricey to clean up your metal pipe. Place on the rubber gloves and disassemble the pipe. Pour the good-grained sea salt into the metal pipe stem and bowl compartment. The salt functions as a scouring agent. Pour a generous quantity of rubbing booze into the finale material sandwich bag. Make positive it is sufficient to submerge the pipe, and put the pipe into the bag. Our more products is SSAW Steel Pipe Tinplate Coil Carbon Seamless Steel Pipe

Steel Pipeline Transportation, a Popular Way of Transporting Gas

What you may not know is that there are more than 70% of gas is transported through pipe line especially black steel pipe. There are hundreds of thousands of kilometers of pipelines crossing the country and the oceans. Most of them are placed underground or undersea, therefore people may not notice them. These pipelines of the black steel pipe are the most important tools to transport gas. They supply energy for our life every time without a break. They contribute great importance to a nation's economy. Many people may thought that this is a way occur in the recent decades; actually they have a pretty long history. The very first kind of pipeline that comes into use in China is bamboo pipe from 400BC; our Chinese people use them to transport waters and gases.

There are mainly several types of materials approved for gas transportation: steel pipes, copper pipes, yellow brass pipe, ductile iron, aluminum pipe, PVC pipes and PE pipes. Each of them has their own advantages and disadvantages. But in general, the most popular type is black steel pipe. To make the transport more high flow and long service time, people became to use black steel pipe. Black steel pipe is hollow circular steel, mainly used in petroleum, chemical, food, light industry, machinery and other industrial transportation. There are many advantages of black steel pipe application of gas. First of all, black steel pipe has good mechanical property, it can stretch; expand flexibly with high pressure resistance and intensity. Secondly, its ability to resist rust and corrosion is excellent. This material can prevent rust, resist oxidation, and it is acid proof, alkali-resisting and anti-corrosion which are its significant advantages. Third, it is heat tolerant and cold resistant.

Mobile Coating Plant is Great News for Black Steel Pipe Producers

In doing so, news methods of applying external coatings are invented to equip the pipes with the capability of anti-corrosion, thermal insulation, and even buoyancy control. One of the most traditional steel pipes, black steel pipe is not galvanized. Because of its dark colored iron-oxide on the external surface, it is also named as black pipe. In general, black steel pipes are applied in the oil industry for the transportation of large amount of oil or petroleum across different areas or regions.

The coating of black steel pipe is typically applied in fixed pipe coating machines which in most cases are located close to the pipe plants. Some manufacturers of black steel pipes use simple anti-corrosion coatings while some others may need to have more specialized coatings, such as concrete-weight coatings or thermal insulation coatings since the pipes may be used in demanding situations. Black welded steel pipe producers either hire workers to complete coating in the plant or outsource the coating job to professional pipe coaters or independent coating suppliers. After the coating procedures and before the pipes are transported to the destinations, thorough and careful examination of the coating quality is usually carried out by the directors of the pipe plants to ensure that their black steel pipes is in line with international standards and with customers' requirements.

The traditional fixed coating plant model works when the black steel pipes are transported to areas not so far from the pipe plants. However, for cross-region or even overseas destinations, the traditional way no longer works well. Luckily, cutting-edge scientific and technological development breeds dramatic changes in the coating facilities. Nowadays, mobile coating plants for black steel pipes are available in many parts of the world, attracting a large number of pipe producers as well as independent coating suppliers.

A mobile coating plant can be easily moved to a new location where the coating services are needed. Obviously mobile coating facilities are beneficial for black steel pipe producers in many aspects. To begin with, more jobs will be created at the communities where the facilities are located, mobilizing locals to work in the pipe plants. Moreover, the flexibility of mobile coating facilities has proved to be efficient and cost-effective, which surely help reduces the production costs for the producers. For independent coating suppliers, mobile coating facilities undoubtedly help optimize the utilization of their professional skills and coating equipment, which may greatly promote their business. Our more products is Flange Reducer Tinplate

The Relationship Between Black Steel Pipe and Tin-plant Production

It is known to us that the supplement of black steel pipe is the main factors to limit the tin-plate production. Black steel pipe producers often also the production of tin plate, and to maintain production cost competitiveness helps to keep the market. That's is why double-sided pure tin electroplating black steel pipe is invented.

The black steel pipe is a kind of cold rolled products, it can be the shear plate, it also can be a coil. Black steel pipe can be used for various of the final product processing and manufacturing , including containers, trays and toys etc.. After coating the organic coating, black steel pipe becomes the double-sided pure tin electroplating black steel pipe, which shows a good corrosion resistance. What's more, when it is in the uncoated condition, whether through single cold or two cold rolling steel plate, black steel pipe is very easy to produce rust, double-sided pure tin electroplating black steel pipe is not.

Over the past 20 years the tinplate industry of black steel pipe, in order to maintain the tin plate in the packaging industry status, there has been in competition with several alternative materials, the main alternative material is plastic, wax paper and aluminum. Speaking of double-sided pure tin electroplating black steel pipe which can also be used on food, beverages and other non food uses, because of its corrosion resistance, formability and weldability, is becoming a main kind of black steel pipe type. The double-sided pure tin electroplating black steel pipe is a new kind of black steel pipe. Tinplate generally has different kinds of oil film surface such as the Sn-Fe alloy layer, the pure tin, or the tin oxide layer. Originally, it is the black steel pipe by annealing and hardening after cold rolling production, but the current trend is to lighter and stronger materials, thus leading to the development of the thickness of tin plate. After annealing and second cold reduction, we can get the double-sided pure tin electroplating black steel pipe.

Generally speaking, there are several ways for double-sided pure tin electroplating black steel pipe production, and to produce good black steel pipe is a basic foundation. One, with the 2 stand reversible cold rolling mill instead of the commonly used 5 stand tandem cold rolling mill, there can be an annual output of 200000 tons of black steel pipe. The mill equipped with the most modern device controls the flatness of black steel pipe, which ensures the highest quality of the surface of double-sided pure tin electroplating black steel pipe coming after. To use various grades of hydrogen batch annealing production from Tl to T6, black steel pipe in higher level don't the need the continuous annealing, but it needs to choose the process and material grade to make sure the double-sided pure tin electroplating black steel pipe can be produces.
