First, the small diameter stainless steel pipe is a continuous online production, the thicker the wall, the greater the unit and the investment in welding equipment, it is more economical and practical. The thickness of the wall is thicker, and its input-output ratio will be correspondingly decreased. Secondly, the process of the product determines its advantages and disadvantages. Generally, the welding pipe has high precision, uniform wall thickness, high brightness inside and outside the tube Surface brightness), can be any length. Therefore, it is in the high-precision, low-pressure fluid applications reflects its economy and aesthetics.
According to the welding technology 304 stainless steel welded pipe can be divided into automatic welding, manual welding. Automatic welding commonly used submerged arc welding, plasma welding, manual welding generally use argon arc welding.
1. According to the form of seam is divided into straight seam welded pipe and spiral welded pipe.
2. 304 stainless steel welded pipe according to the purpose is divided into general welded pipe, heat exchanger tube, condenser tube, galvanized pipe, blowing oxygen pipe, wire casing, metric pipe, roller tube, deep well pump, automotive pipe, transformer tube, Tube, welded welded pipe and spiral welded pipe.
