Api 5l X42 Psl2 Line Pipe
API 5L X42 pipe is also known as L290 pipe (per ISO 3183), named after the minimum yield strength of 42100 Psi or 290 MPa.
Oil pipe specifications: 8-1240×1-200mm.
The outer diameter of oil pipes generally ranges from 60.3 mm to 114.3 mm.
The end processing forms of oil pipes include: non-thickened with threads and couplings, externally thickened with threads and couplings, plain end, non-thickened with threads and couplings, externally thickened with threads and couplings.
