Torsion on Open Section Beams and Pipe Supports Design

In the last twenty years, with the increased use of 3D modelling in the O&G industry, most of the EPC companies have progressively passed the pipe supports selection and design duties from Stress Engineers and Pipe Supports Specialists to Piping Designers, who are directly involved in the 3D modelling. This handover has generally not been supported by a structured knowledge transfer, which has…

Introduction to Priming in Pumps

First of all lets try to get a brief of What is a Pump?

Pump is a machine or mechanical equipment which is required to lift a fluid (liquid, semi-solid, gas, steam etc) from low level to high level or to flow fluid from low pressure area to high pressure area or as a booster in a piping network system. Principally, pump converts mechanical energy of motor into fluid flow energy.

Introduction to Ball Valve

A ball valve is a form of quarter-turn shut-off valve that controls the flow of a liquid or gas by means of a rotary ball with a hole bored through the center and sandwiched between two seats. Ball valves do not use a hand-wheel but instead use a wrench handle to control the flow. A 90° turn of the wrench opens or closes the valve. It is open when the ball’s hole is in line with the fluid flow…

Introduction to Double Block and Bleed Valve System

A Block and Bleed Valve System is a combination of one or more block/isolation valves, usually ball valves, and one or more bleed/vent valves, usually ball or needle valves. The purpose of the block and bleed valve system is to isolate or block the flow of fluid in the system so the fluid from upstream does not reach other components of the system that are downstream. This enables the engineers…

Introduction to Butterfly Valves

Butterfly Valves are quarter-turn rotary valves in which a disc-shaped closure member is rotated through 90 degree or less to open or close or regulate the flow passage. Butterfly valves may be used for flow in both directions. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

Because the disc…

Introduction to Check Valves

Check Valves, also known as Non Return Valves (NRV) or One Way Valves, are automatic valves that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valve open with forward flow and close against reverse flow. Check valves differ considerably from other members of the valve family and the prime function of a check valve is to protect mechanical equipment in a…

Introduction to Needle Valve

Needle Valves, sometimes referred also as Plunger Valves, are regulating valves and enable engineers to finely control and regulate fluid flow and pressure. Needle valves are similar to the globe valve in design with the biggest difference is the sharp needle shaped disk.Needle valve have a small port and a threaded needle-shaped plunger. This arrangement permits a very gradual increase or…

Introduction to Globe Valve

Globe valves are linear motion closing-down valves in which the closure member is moved squarely on and off the seat. Usually the closure member is referred as a disc, irrespective of its shape. The seat opening varies in direct proportion to the travel of the disc. This proportional relationship between valve opening and disc travel is ideally suited for duties involving regulation of flow rate.…

Introduction to Gate Valve

Gate valves are used to shut off the flow of fluid by inserting a rectangular gate or wedge into the path of a flowing fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened enabling gate valves to offer straightway flow with very little pressure drop. Gate valves are mostly used with larger pipe diameters (from 2″ to…

A Short Article on Mechanical Fasteners

A mechanical fastener is a device that is used to mechanically join (or fasten or affixes) two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.

A welding joint or riveted joint can be termed as a permanent joint, which if required to be removed tends to damage or…

A Short Article on Elbow as Pipe Fitting

Steel pipe elbow (sometimes also refereed as bends) is a key part in a pressure piping system used to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe and thus the fluid direction turn to a certain direction of 45 degree or 90 degree. This change in fluid flow direction adds pressure losses to the system due to impact,…

A Short Article on Coupling as Pipe Fitting

A Pipe Coupling, used in piping or plumbing, is a very short length of pipe or tube with either socket or female pipe threads at one or both ends that allows two pipes or tubes of equal or different sizes to be joined together. Couplings are pipe fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. It’s also used to repair a broken or leaking pipe.

A Short Article on Nipple as Pipe Fitting

In piping, a nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other female threaded fittings or pipes. Pipe Nipples are commonly used as adapters from one connection type to another. Pipe nipples are mainly used in low-pressure piping systems.

Pipe nipples are manufactured by cutting a specified length of pipe and…

Introduction to Pipe

A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey products from one location to another. The products must be able to flow. These includes liquids and gases (fluids), slurries, powders and masses of small solids.

Difference between Pipe and Tube

In common usage the words pipe and tube are usually interchangeable, but in…

Introduction to Welded Pipe Manufacturing

Steel pipes are long, hollow tubes that are used mainly to convey products from one location to another. They are produced mainly by two distinct manufacturing methods which result in either a welded pipe or seamless pipe. In both the manufacturing methods, raw steel is first cast into a more workable starting form (hot billet or flat strip). It is then made into a pipe by stretching the hot…

Introduction to Sample Cooler

Sample Coolers are small shell and tube heat exchangers that are used to cool the sample from a process stream to the required temperature conditions for safe and immediate analysis. It is one of the most critical components of a sampling system suitable for most applications in liquid, gas or steam process. The sample to be cooled flows through the tube side of the cooler, and the cooling fluid,…
