Process Technology Of Welded Steel Pipe

　　The smaller diameter of the pipe are mostly straight seam welding, large diameter welded pipe is mostly used spiral welding. Added: welded pipe is welded with steel, so in its original position is not seamless high.Welded steel pipe according to the welding method can be divided into different arc welding pipe, high frequency or low frequency resistance welded steel pipe, gas pipe, furnace pipe, Bundy tube.

　　Welded steel pipe: for oil drilling and machinery manufacturing industry. Welded pipe: can be used as water and gas pipes, large diameter straight seam welded pipe for high pressure oil and gas transportation; BS 1387 Heavy Grade Black Welded Steel Pipe for oil and gas transportation, pipe piles, piers and so on.Welded Steel Pipe Welded steel pipe, also known as welded pipe, is made of steel or steel strip after crimping made of welded steel pipe. Welding steel pipe production process is simple, high production efficiency, variety specifications, equipment investment, but the general strength is lower than the seamless steel pipe. Since the 1930s, with the rapid development of high-quality strip rolling and the improvement of welding and inspection technology, the quality of welds has been increasing Welded Steel Pipecontinuously, and the specifications of welded steel pipes have been increasing and more and more fields have been replaced. Sewing steel pipe. Welded steel pipe in the form of welds are divided into straight seam welded pipe and spiral welded pipe.
