Carbon steel head manufacturer to ensure that the

Carbon steel head manufacturer to ensure that the production of wasteCarbon steel head (pipe cap), also known as plug, cover, pipe cover, head, used to close the pipeline, the same function and pipe plug, but the pipe cap can be directly screwed on the pipe, do not need other pipe fittings.  Carbon steel is an iron carbon alloy with carbon content ranging from 0.0218% to 2.11%.  Also called carbon steel.  Generally also contains a small amount of silicon, manganese, sulfur, phosphorus.  The higher the carbon content of general carbon steel is the greater the hardness, the higher the strength, but the plasticity is low.

The head includes convex pipe cap, conical shell, reduced diameter section, flat cover and tight mouth design.  Convex pipe cap includes: hemispherical pipe cap, oval pipe cap, disc pipe cap and dome pipe cap.  From the point of view of force, convex pipe cap is gradually bad from the hemispherical pipe cap, but from the point of view of manufacturing difficulty, gradually good manufacturing.  Weld direction is only allowed to be radial and circumferential.  This requirement may be removed for larger caps in the future.  The splicing distance should be greater than 3δ and not less than 100mm (the weld heat affected zone is a high stress zone, and there will be burning loss of chemical composition in this zone.  So avoid areas of high stress, which are related to thickness.  According to practical experience, the stress attenuation length is greater than 3δ and not less than 100mm).  But refrigeration equipment is difficult to meet this requirement, has its particularity.  Large diameter spinning carbon steel pipe cap, diameter 1520*16 spinning carbon steel pipe cap cold forming.  Tube cap production: welding before forming: guarantee welding quality (surface inspection, pay attention to welding current, welding method of carbon steel tube cap, etc.), ray inspection.  Internal grinding is flush with base metal before stamping.  X-ray detection after molding.  Partial welding after forming: guarantee welding quality (surface inspection, pay attention to welding current, welding method, etc.), ray inspection.

In order to make the spinning head in the process of welding, the weld seam should be far away from the corner transition zone with large tensile deformation in the head stamping, so as to avoid the splicing weld being damaged at large deformation.  For this purpose, DN600 caliber carbon steel pipe cap is used for storage tanks. There are certain restrictions on the weld position of head splicing, but after practice, it was found that this is easy to cause waste of materials, and can not ensure the quality of weld deformation.

Our company in the production of pipe cap products, the company uses customer specified requirements to make forming, to ensure that the production of pipe cap products will not waste material, time and labor.
