API 5L ERW pipe is resistance welded pipe that meets American Petroleum Institute (API) standards. This kind of pipe is usually used in the oil and gas industry to transport natural gas, oil and other fluid media. API 5L is an API standard used to regulate line pipe, while ERW indicates that the pipe is manufactured through a resistance welding process.
Â
The manufacturing process of API 5L ERW pipe (resistance welded pipe) involves rolling steel plates into a pipe shape and then welding them using resistance heating to create a weld that runs along the length of the pipe. The chemical composition of API erw pipe mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. API 5L is a standard used to regulate pipeline pipes in the oil and gas industry . It stipulates the chemical composition, mechanical properties, manufacturing process and other requirements of pipeline steel. API 5L ERW steel pipe must comply with these relevant regulations to meet the standard.
Â
API 5L ERW welded pipe is mainly used to transport oil and gas products, including natural gas and petroleum. This kind of pipeline is usually used for long-distance transportation, so it needs to be able to withstand high pressure and corrosion resistance. In addition, it can be used to transport other gases and liquids.
