What is API Standards For Line Pipe

Exactly what is API?

 

API standard

The American Petroleum Institute( API), established in 1919, is the biggest petroleum and natural gas industry association in the United States. The primary contribution of API is to establish a series of requirements for oil and gas industry in accordance with ecological and legislative requirements. Far, API is one of the most successful and popular documents.

API requirement for pipeline

 

API 5L pipe production is presently using micro alloy heating treatment process. The production costs of seamless stainless-steel pipe are significantly higher than the welding pipe and with the boost of steel grade, the limitation of carbon content is a growing number of stringent. At present, all the significant makers perform research study work in order to improve the rust resistance of the pipeline and ensure the steady performance in low and high temperature level.

 

API requirement for pipeline

PSL is referred to as the level of product specification. The product specification of the pipeline is divided into PSL1 and PSL2, there is a difference of only a single word, but the content of these 2 standards are totally different. The quality level of PSL2 is greater than that of PSL1, these 2 standards are not only different from the inspection requirements, but likewise the chemical structure and mechanical homes are different.
