Welded steel 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, the variety specifications of welded steel pipes are increasing, and in more and more fields, especially in the heat exchange of spare pipes, decorative pipes, medium and low pressure fluid pipes and other aspects of the replacement of seamless steel pipes.
Sant has advanced on-line solution annealing, on-line eddy current testing equipment; ET-Ⅱ non-destructive testing personnel qualification; Professional airtight pressure test equipment; The annual output of stainless steel heat exchange straight pipe is more than 2000 tons.
The above contents are arranged by stainless steel heat exchanger manufacturers.
