The particularity of pipe cap in pipeline installation  

The company mainly produces a variety of different specifications and models of pipe cap products, the material of the pipe cap is divided into: carbon steel, alloy steel, stainless steel, etc., pipe cap is mainly welded in the pipe end installed on the pipe end of the outer thread to cover the pipe fittings, used to close the pipe, the effect on the pipe plug the same.  

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.  

For the head formed after splicing, splicing weld shall be tested by 99%+1% ray or ultrasonic, and the qualified level shall follow the equipment shell.  The final forming welding joint detection level, proportion and equipment shell is the same, high waste.  Example: if the equipment housing is 20% tested, III qualified.  The closed splicing weld and the final weld are also III qualified, and the welding joint coefficient is 0.85;  

If the equipment housing is 99%+1% test, II is qualified.  The bulkhead splicing weld and the final weld are also II qualified, and the welding joint coefficient is 1.  

Pipe cap is mainly used for: water, petrochemical, nuclear power, machinery, water treatment, pipeline safety and transfer.
