Improve the performance of stainless steel butt welding elbow
Stainless steel butt welding elbow everyone is not strange, for people familiar with pipe fittings is to understand
Next we talk about the characteristics of stainless steel butt welding elbow
Stainless steel butt welding elbows are usually manufactured according to actual engineering regulations or actual design drawings.In addition to the additional attention to pipe diameter requirements, you also need to pay attention to the pipeline transport pressure, hydromechanical viscosity, damage, erosion, hydromechanical transport temperature and other specific conditions. stainless steel butt welding elbow manufacturers will tell you in detail when installing stainless steel butt welding elbow to pay attention to things.
Common precautions for stainless steel butt welding elbows
Electrode installation and application should be dry, titanium type should be dried at 150℃ 1h, low hydrogen type should be dried at 200~250℃, in order to avoid sticking oil and other dirt caused by the increase of carbon content of the weld, harm the quality of welding parts, in order to avoid heating caused by corrosion, welding process current can not be too large, than carbon steel electrical rarely 20% up and down, arc need not be too long, Rapid cooling between layers, narrow weld.
In order to improve the corrosion resistance and weldability of stainless steel butt welding elbow, stable elements such as Ti, Nb and Mo are properly added. The welding process performance of large stainless steel butt welding elbow is better than that of elbow. When selecting better kinds of chromium stainless steel electrode, preheating above 200℃ should be carried out, and tempering about 800℃ after welding process. Chrome-nickel stainless steel electrode should be used.
The above is to improve the characteristics of stainless steel butt welding elbow explain knowledge, I believe if you are interested in stainless steel butt welding elbow, see this article to have a good read, because this is our professional experience, want to know more about stainless steel butt welding elbow knowledge, please pay attention to the website.
