 Stainless steel welded pipes processing is easy to cause certain changes to the inside or outside of stainless steel welded pipes. Stainless steel welded pipe welding: Before processing and welding stainless steel welded pipes, rust, oil, water, paint, etc. that are harmful to welding should be thoroughly removed, and an electrode suitable for the steel grade should be selected. The processing time interval of stainless steel welded pipe is shorter than that of carbon steel spot welding. Stainless steel welded pipe brush should be used to remove welding slag. After welding, in order to prevent local corrosion or strength reduction, the surface should be polished or cleaned. Stainless steel welded pipe processing, cutting and stamping: Because stainless steel welded pipe have higher strength than general materials, higher pressure is required for stamping and cutting. When the gap between the knife and the knife is accurate, poor shearing and work hardening will not occur. Plasma o...

 With rising international demand for for anti-corrosion pipes, Xinyue’s anti-corrosion pipes orders have shown an upward trend in recent years. Steel pipe anti-corrosion methods generally use coating anti-corrosion. Coating anti-corrosion is a uniform and dense coating on rust-removed surface, in this way, pipe is isolated from various corrosive media. It is one of basic method for steel pipe anti-corrosion. The surface treatment of steel pipes, mainly by high-power motors, drives the jet blades to spin steel grit, steel shots, wire segments, minerals and other abrasives at high speed under the action of centrifugal force. In addition, the steel tube can achieve the required uniform roughness under the action of the violent impact of abrasive and friction. So it will meet the requirements of anticorrosive coatings. Coating anticorrosion is divided into the following types?cement mortar lining protection, liquid epoxy coating, FBE fusion bond epoxy, bitumen coating, 3LPE / 3LPP, po...

 Low temperature quenching is a heat treatment process that strengthens the crystal structure of metals at temperatures below -150 ° C (-238 ° F). It is known that the low temperature treatment of certain materials can have a positive impact on three aspects: 1. Durability is more durable: low temperature quenching helps to promote the transformation of residual austenite in the heat-treated steel into harder martensite. This process will significantly reduce defects in the crystal structure of steel. 2. Improve abrasion resistance: Low-temperature quenching increases the precipitation of η-carbides. This fine carbide acts as a binder in the martensitic matrix and helps the martensitic steel resist wear and corrosion. 3.Relieve stress: All metals have residual stress. Residual stress is the force generated during the solidification of a metal from a liquid to a solid. These stresses will make the state susceptible to changes (often unfavorable). Low temperature quenching can reduce...
