Appearance contrast:

1. appearance stainless steel tube generally white and no embroidery. The surface of ordinary seamless steel pipe will have floating embroidery or reddish brown.

Stainless steel is resistant to corrosion and finish is much better than ordinary steel pipes. Wait

 

2. seamless steel pipe technology is drawn, without welding seam, material can be ordinary No. 20 steel, also can be stainless steel.

Ordinary stainless steel pipes are usually welded on technology and stainless steel.

 

Stainless steel seamless pipe is a kind of long steel with hollow section and no joints around it. The thicker the wall thickness of the product, the more economical and practical it has, the thinner the wall thickness, the more its processing cost will rise; the product's process determines its limited performance, the general seamless steel pipe is of low precision, the wall thickness is not uniform, the inside and outside surface of the tube is low, the scale is high, and the internal and external table is also pock, black spot. It is difficult to remove; its detection and reshaping must be off-line. Therefore, it manifests its superiority in high pressure, high strength and mechanical structure.

 

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. .
