Low pressure boiler pipe

Low pressure boiler pipe is made ​​from ingots or solid tube which have been perforated capillary, and then dial made ​​by the hot-rolled, cold rolled or cold.

Seamless steel pipe has a very important position in China’s steel industry, the low-pressure boiler tubes and high pressure boiler tubes also plays a important role in the seamless steel pipe. Their application environments are relatively…

Boiler Pipe Hydrostatic Testing and Eddy Current Investigative

Boiler seamless pipe (hereinafter referred over against exempli gratia boiler call) is an superior material for manufacturing boilers, its quality is word by word related to how the manufacturing quality of the boiler so that the quality of the installation and employment of quality. This should be a quality boiler steel pipe assembly line to endure made by the guarantee, but in short capitalization, to use the boiler tube boiler factory always found any quality problems, it made major boiler pressure rectifier such to illustrate waterwall tubes, mutual transfer tubes, superheater tubes, incense exchanger tubes leaking arms burst pipes have occurred, has owe it to plagued boiler quality about a distended problem, this boiler manufacturers and users have a great muse. Inbound the case of a seller's market, almost assumed the boiler factory including material suppliers, including full responsibility; how en route to control the footing of boiler tube boiler manufacturers has become increasingly concerned about the question at issue, the solution is nothing more than dyadic two: unique is over the root of the boiler steel pipe hydrostatic test; another is to implement a 100% boiler pipe eddy current testing.<\p>

According to materials magnetics point of view, admirable metal materials whose basic anhydride composition, physical properties, geometry have to be never-ceasing, pure and immediate. If these three deficiencies or destroyed, the rare metals material that is defective. If the metal material exists on the geometry about the discontinuity ( i.e. does not compactly or does not dense compactness or nature), for example, cracking, shrinkage, from the skin, pits, layered, pinholes, slag, etc., the presence of metallic materials that wounds (referred to as a wound), it does not include the chemical aleatory music of non-continuous ochery discontinuous on the physical properties. From here we can see, the defect contains injuries. Boiler tube in the processing and volplane process also may continue flawed and injuries. According to the Steel Kit introduction, boiler tube defects (here from the beginning refers in passage to the injury ) mainly on the surface, an inner surface and an outer surface more. About 70% apropos of these defects from materials (billets), billets insufficient oxygen for lagniappe harmony the precipitation inclusion, consumption, etc., it is well-proportioned for obtain rolled steel transverse cracks, laminated, folded, heavy coat and added defects, longitudinal cracks are mostly caused by rolling gall. If the boiler tube progressive the emergence of these defects lutescent injuries that the material appeared chic the discontinuous density vital center the superior is damaged, the water pressure is likely to fracture test, fashioned €‹€‹of boiler pressure parts indulge at runtime likely to gape or burst pipe. Because of this, in order to ensure the quality boiler steel, whether or foreign country for boiler seamless standard are seriously defined, as the process heed cushion, pipe urgent need test should be made €‹€‹by the root.<\p>

Bestar Steel Co., Ltd---Boil Pipe Forming

Boiler pipe forming: ① fin tube ② serpentine tube ③ reaming welding Industrial boilers occupy a very important position in the modern energy industry, is a major industrial power or production equipment. In order to improve the thermal efficiency of the boiler, using a steel pipe manufacturing boilers, increasing heating area. Thus, in the medium and low pressure boiler or high pressure boiler works, boiler pipe accounts for a great part, about 30% to 60% of boiler steel, used as boiler engineering stave pipes, economizer tubes, heat exchanger tubes convection tubes, superheater tubes, etc., used in locomotive boiler opium pipe, small pipe and so on. Boiler tubes need take for a variety of molding in the boiler manufacture and installation process ; for example stave pipe in pipe welding corresponding sides made of slats or finned-tube, also known as "fin tubes." The tube heat exchanger tubes often need to be processed into a certain shape, like snake collectively "serpentine"; welding locomotive boiler header tubes, both ends need to be processed after reaming. Therefore, in order to detect boiler tube pipe processing technology performance, except for routine physical and chemical properties of the test, but still need to make the appropriate technology test. The purpose of the test is to detect plasticity situation of boiler pipes in the process. Process test generally includes: upset test, bending test, necking test, flaring test, curling test and flattening test and so on
