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%.
