Welded Stainless Steel Square Tube
A welded stainless steel square tube is a type of stainless steel tube with a square cross-section that is manufactured using a welding process.
Stainless steel welded pipe is a kind of stainless steel pipe connected by welding. The production process of stainless steel welded pipe is simple, the production efficiency is high, there are many varieties and specifications, and the equipment investment is low, but the general strength is lower than that of seamless steel pipe. According to the welding characteristics of stainless steel, the heat input should be minimized as much as possible. Generally, two methods are used: manual arc welding and tungsten arc welding. For Φ>100 mm, the argon arc welding base and arc welding filler cover are used. Pipes with Φ≦100 mm and wall thickness less than 5mm shall be fully argon arc welded. Pipes with wall thickness greater than or equal to 5mm shall be argon arc bottomed and arc welded to fill the cover.
It is mainly used to transport various liquids, gases and solid particles, such as petroleum, chemical, pharmaceutical, food and other industries that require the use of stainless steel welded pipes for transportation. Stainless steel welded pipes have the characteristics of corrosion resistance, high temperature resistance and high strength, which can ensure that there will be no leakage, corrosion and other problems during the transportation process, thereby ensuring the safety and stability of the production process.
