Stainless steel welded pipe classification and characteristics
(a) Classification by process - gas shielded welded pipe, arc welded pipe, electric resistance welded pipe (high frequency, low frequency)
(b) According to the weld seam - straight seam welded pipe, spiral welded pipe
Stainless steel welded steel pipe is referred to as stainless steel welded pipe, which is a steel pipe made by welding a stainless steel plate or a steel belt through a unit and a die.

◆Features of welded steel pipe
First of all, the product is continuously produced online. The thicker the wall thickness, the greater the investment of the unit and the welding equipment, and the less economic and practical it is. The thinner the wall thickness, the lower the input-output ratio will be;
Secondly, the process of the product determines its advantages and disadvantages. Generally, the welded steel pipe has high precision, uniform wall thickness, high brightness inside and outside the pipe (the surface brightness of the steel pipe determined by the surface grade of the steel plate), and can be arbitrarily fixed.
Therefore, it demonstrates its economy and aesthetics in high-precision, medium- and low-pressure fluid applications.
