API 5L


Generally speaking, API 5L refers to API 5L line pipe,which is out of the ground the oil, gas, water, transported by pipeline to pipe oil and gas industry companies.

according to the manufacture process and the tube bloom used different shapes, api 5l can be divided into api 5l seamless steel pipe and api welded steel pipe, among the usage quantity of welded steel pipe is more than seamless steel pipe.

Line pipe grade and chemical components
API 5L can be divided into API 5L PSL 1 and API 5L PSL 2, including API 5L PSL 1 level and the categories are: A, B, x42, x46, x52, x56, x60, x65, x70, API 5L PSL 2 level and the category is B, x42, x46, x52, x56, x60, x65, xx70, x80. the higher the level the stronger mechanical properties.

Application: used for oil and gas industry, gas, water, oil transportation.
