Standard for spiral welded steel pipes:
GB/T？ 9711-20165438+grade b steel pipe), API-5L (api gravity, also known as pipeline steel pipe; Including PSL 1 and PSL2) and SY/T5040-92 (spiral seam submerged arc welded steel pipe for piles).
Classification of spiral welded steel pipes;
According to different welding methods, it can be divided into arc welded pipe, high-frequency or low-frequency resistance welded pipe, gas welded pipe, furnace welded pipe and Bundy pipe. According to the weld shape, it can be divided into straight welded pipe and spiral welded pipe. Welded steel pipes are used in oil drilling and machinery manufacturing. Furnace welded pipes can be used as water pipes and gas pipes, and large-diameter straight welded pipes can be used for high-pressure oil and gas transportation. Spiral welded pipe is used for oil and gas transportation, pipe piles, piers, etc. Welded steel pipe has lower cost and higher production efficiency than seamless steel pipe.
The production process of straight welded pipe is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. Welded pipes with larger diameters can be produced from narrow blanks, and welded pipes with different diameters can also be produced from blanks with the same width. However, compared with the straight seam pipe with the same length, the weld length increases by 30~ 100%, and the production speed is lower. Therefore, straight seam welding is mostly used for welded pipes with smaller diameter, and spiral welding is mostly used for welded pipes with larger diameter.
