316 Welded Seamless Tubing

Stainless steel pipe classification: The pipe is divided into seamless steel pipe and welded steel pipe (welded pipe) two categories. According to the section shape can be divided into square and rectangular pipe, widely used is round steel pipe, but there are also some semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel pipe.
For the stainless steel pipe under fluid pressure to carry out hydraulic tests to test its pressure resistance and quality, under the specified pressure does not leak, wet or expansion qualified, some steel pipe also according to the standard or the requirements of the demander flange test, flaring test, flattening test and so on.

Product Introduction

Stainless steel welded pipe, referred to as welded pipe, commonly used steel or steel strip after the unit and mold crimped forming welded steel pipe. Welded steel pipe production process is simple, high production efficiency, variety specifications, less equipment investment, but the general strength is lower than seamless steel pipe.
Since the 1930s, with the rapid development of high-quality strip continuous rolling production and the progress of welding and inspection technology, the quality of welds continues to improve, and the variety specifications of welded steel pipes are increasing, and in more and more fields, especially in the heat exchange equipment with pipes, decorative pipes, medium and low pressure fluid pipes and other aspects of the replacement of seamless steel pipes.
