How to deal with seamless steel pipes after welding?

(1) After the seamless steel pipe is welded, the residual flux and welding penetration remaining in the welding and surrounding areas will destroy the passivation treatment film on the surface of the medium and thick plate, and sometimes continue to etch the seamless steel pipe, so it should be cleaned and clean. Welding through the surface of the seam steel pipe, etc. Seamless steel pipes with simple appearance and general regulations can be removed by simple methods such as boiling water washing or steam blowing.

(2) Post-weld heat-treated seamless steel pipes generally do not require heat treatment after welding.
Plate is one of the important rare metal types. Because of its excellent characteristics (small relative density, good plastic deformation and formability characteristics) and easy acquisition, pure medium and heavy plates have long become the key basic raw materials in household appliances. It is generally used to rebuild components such as heating parts and conductive parts of household appliances. The reuse of waste seamless steel pipes has long become an important part of the reuse of rare metals, and its energy consumption and re-incurred costs are much lower than those of the original wear-resistant steel pipes (about 10%).
