Characteristics

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

Welding characteristics

According to the welding technology, it can be divided into automatic welding and manual welding. Automatic welding generally uses submerged arc welding and plasma welding, and manual welding generally uses argon arc welding.

 

classification

According to the weld form, it is divided into straight welded pipe and spiral welded pipe.

According to the application, it is divided into general welded pipe, heat exchanger pipe, condenser pipe, galvanized pipe, oxygen-oxygen welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welding thin wall. Tube, welded profiled tube and spiral welded pipe
