The specification range of API 5L Class B pipe is usually ∮60-508×4-30.
API 5L Class B pipeline is a kind of pipe for oil and natural gas industry transportation, and its execution standard is API SPEC 5L. This kind of pipeline is mainly used to transport gas, water, oil and other media, and has a wide range of applications. The ∮ in the specification range represents the outer diameter of the pipe, 60-508 represents the outer diameter ranging from 60 mm to 508 mm; 4-30 represents the wall thickness of the pipe ranging from 4 mm to 30 mm.
