Introduction of stainless steel welded pipe

Date:2018/7/28 9:05:37


Welded steel pipe is simply welded pipe, usually steel or steel strip welded by the unit and die after welding. Welded steel pipe production process is simple, high production efficiency, variety specifications, equipment investment is small, but the general strength is lower than seamless steel pipe. Since the 1930s, with the rapid development of high quality strip steel continuous rolling production and the progress of welding and inspection technology, the weld quality has been improved, the variety and specification of welded steel pipe is increasing, and the seamless steel pipe has been replaced in more and more fields, especially for the spare tube, decorative pipe, medium and low pressure fluid pipe, etc. .

 


Characteristic:

Firstly, the small diameter stainless steel welded pipe is continuously produced on-line. The thicker the wall thickness is, the greater the investment of the unit and the melting equipment is, and the less economical and practical it is. The thinner the wall thickness, its input-output ratio will decrease correspondingly; secondly, the technology of the product determines its advantages and disadvantages, the high precision of the welded pipe, the uniform thickness of the wall, the high brightness of the inside and outside of the tube (the surface brightness of the steel tube determined by the surface grade of the steel plate), and the arbitrarily fixed ruler. Therefore, it manifests its economy and aesthetics in the application of high precision, medium and low pressure fluid.

 


Classification:

It is divided into longitudinal welded pipe and spiral welded pipe according to weld form.

 


It is also divided into general welding pipe, heat exchanger tube, condenser tube, galvanized pipe, oxygen blowing pipe, wire sleeve, common pipe, roller tube, deep well pump tube, automobile pipe, transformer pipe, welding thin tube, electric welding special-shaped tube and spiral welded pipe.
