Description
API 5L PSL1 pipeline steel pipe
API 5L is the implementation standard of pipeline steel pipe, and PSL is short for product specification level. The product specification level of pipeline steel pipe is divided into PSL1 and PSL2. PSL1 is less strict than PSL2 in terms of inspection requirements, chemical composition, mechanical properties and other indicators. Pipeline steel pipe is used to pump oil and natural gas from the ground to the oil and gas industry. Pipeline steel pipe includes seamless steel pipe and welded steel pipe. Welded pipe is connected by capacitive electric welding. Generally speaking, the length of pipeline steel pipe is long and can be used on a large scale, but the stability is not as good as seamless steel pipe, but the length of seamless steel pipe is generally short and can not meet the long-distance use.

Application
Pipeline steel pipe has the advantages of high temperature resistance and loss reduction, and the pipe is generally very strong and durable. It is because of the strong advantage of pipeline pipe that it is widely used in the transportation of various gases and liquefied gas. In addition to being applied in the chemical industry and petroleum industry, Pipeline pipes are also widely used in heating and water supply systems in large factories. In urban construction, pipeline pipes are also used as the transport carrier of gas and natural gas to provide clean, environmentally friendly, efficient and energy saving new energy for the city.
