Carbon steel straight seam steel pipe is made of carbon steel. Carbon steel is also called carbon steel. It refers to iron-carbon alloy with carbon content Wc less than 2.11%. Carbon steel generally contains a small amount of silicon, manganese and sulfur in addition to carbon. phosphorus.
Generally, the higher the carbon content of carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.
According to the production process, carbon steel straight seam steel pipes can be divided into high-frequency straight seam steel pipes and submerged arc welded straight seam steel pipes. Submerged arc welded straight seam steel pipes are further divided into UOE, RBE, JCOE steel pipes according to their different molding methods.
GB/T14980-1994 (large diameter electric welded steel pipe for low pressure fluid transportation)
GB/T9711-1997 [Oil and natural gas industrial conveying steel pipe, including GB/T9771.1 (representing A grade steel) and GB/T9711.2 (representing B grade steel)]
Carbon steel straight seam steel pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. For liquid transportation: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural use: for piling pipes, for bridges; for piers, roads, building structures, etc.
