Astm A106 A53 Carbon Steel Seamless Pipe
Seamless carbonsteel pipe is a capillary tube made of steel ingots or solid tube blanks through perforation, and then made by hot rolling, cold rolling or cold drawing. Seamless carbon steel pipes have an important position in my country's steel pipe industry. According to incomplete statistics, there are more than 240 seamless carbon steel pipe manufacturers in my country, and more than 250 seamless carbon steel pipe units, with an annual production capacity of about 4.5 million tons. In terms of caliber, those with <φ76 accounted for 35%, and those with <φ159-650 accounted for 25%. In terms of varieties, 1.9 million tons of general-purpose pipes, accounting for 54%; 760,000 tons of petroleum pipes, accounting for 5.7%; hydraulic props and precision pipes of 150,000 tons, accounting for 4.3%; stainless pipes, bearing pipes, and automotive pipes totaling 50,000 Tons, accounting for 1.4%.
