Application of stainless steel pipe cap welding

Application of stainless steel pipe cap welding  

 Stainless steel pipe caps are made in radial and circular direction according to the direction requirements of customers in the production process. Later, this requirement may be cancelled for large pipe caps.  Stainless steel pipe cap is mainly used as pipe plug during pipeline installation.  

Stainless steel cap material: 304 304L 316 316L 321 2520 310, 317, and other materials.  

Stainless steel cap size: DN15-DN1200  

Wall thickness of stainless steel pipe cap: SCH5-SCH160  

ASME DIN JIS BS GB/T JB SH HG  GB/T12459-2005, GB/T13401-2005, ASME B16.9, SH3408, SH3409, HG/T21635, DL/T695, SY/T0510, DIN2617  

The use of stainless steel pipe cap: water, beverage, beer, food, petrochemical, nuclear power, machinery, chemical fertilizer, shipbuilding, water treatment, pipeline, etc  

Stainless steel tube cap packaging: wooden case, carton service: provide technical advice, installation guidance, etc  

Avoid splicing at the pipe cap, which will reduce thin and high stress.  

The weld direction of the pipe cap 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. &a
