First, the small diameter 304 stainless steel welded pipe is continuously produced online. The thicker the wall thickness, the greater the investment in the unit and the welding equipment, the less economic and practical it is. The thinner the wall thickness, the lower its input-output ratio will be;
Second, the product's technology determines its advantages and disadvantages, generally 304 stainless steel welded pipe with high accuracy, uniform wall thickness, high brightness inside and outside the pipe (surface brightness of the steel pipe determined by the surface grade of the steel plate), can be arbitrarily determined. Therefore, it reflects its economy and aesthetics in the application of high precision, medium and low pressure fluids.
