Introduction：
Carbon steel pipes are widely used in the oil and gas industry, shipbuilding, energy industry, automobile and machinery industries due to their high strength, durability and high pressure resistance.
The main components of carbon steel pipes are iron, carbon and other small amounts of elements such as manganese, silicon and copper. The production standards are usually ANSI, ASTM and API. The sizes range from 1/2 inch to 24 inches.
