Stainless steel pipe cap manufacturer's guara

Stainless steel pipe cap manufacturer's guarantee of material  

Stainless steel pipe cap manufacturers mainly produce various types of pipe cap complete.  Pipe cap is a product mainly used for pipe installation.  

Stainless steel pipe cap is also known as stainless steel head, stainless steel pipe cap structure stress size cooling speed, shape materials and chemical composition and other factors.  

The material of stainless steel tube cap is mainly divided into:  304L, 321, 316, 316L, 310S, 00Cr18Ni5Mo3Si2 (UNS S31500) (3RE60), 630, 00Cr22Ni5Mo3N (UNS S31803/S32205) (SAF2205)  00Cr25Ni7Mo4N (UNS S32750) (SAF2507)304, 1Cr13, 2Cr13, 3Cr13, 1Cr17Ni2, duplex steel and other materials.  

The main use of stainless steel pipe cap: welded on the pipe end or installed on the pipe end of the external thread to cover the pipe fittings, used to close the pipeline.  The effect is the same as pipe blocking.  Stainless steel pipe caps are removable plugs, while welded pipe caps are not.  The tube cap is the part of the container. According to the different geometry, it can be divided into spherical, flat cap and other shapes.  

Stainless steel pipe cap mainly includes: hemispherical pipe cap, butterfly pipe cap and ball crown pipe cap, from the point of view of force convex pipe cap from the hemispherical pipe cap gradually bad, but from the manufacturing difficulty, gradually good manufacturing.  

Stainless steel pipe cap widely introduced: pipe cap welding residual stress, stable pipe cap structure shape and size, reduce distortion;  Improve the performance of pipe cap base material and welding area.  Including improving the plasticity of weld metal;  Reduce the hardness of heat affected zone; Increase fracture toughness;  Improving labor intensity;  Improve creep characteristics;  Restore or improve the yield strength reduced in cold forming;  Improve the ability of pipe cap stress corrosion resistance, further release the harmful gas in the pipe cap weld metal, especially hydrogen, prevent the occurrence of delayed crack.
