What is API 5L X42 Pipe is?
API 5L X42 pipe also called L290 pipe (by ISO 3183), named by minimum yield strength 42100 Psi or 290 Mpa. It’s a higher grade than Grade B where API 5L has various grades up to X100, so x42 pipe is an low-medium level, and it requires large quantities in most of pipelines for oil and gas transmissions.Standard package of API 5L X42 Seamless and ERW Pipe is available in bundles or loose. It comes tightened with special packing, iron strips, pallets, metal or wooden, etc.
C&N offers API 5L X42/L290 steel pipe in welded ERW and HFW, LSAW, SAWH and seamless. Product specifications are PSL1 and PSL2 in sizes from the usual 4”, 6”, 8”, 10”, 12”, 16”, 20” to 60”
Ranges by Manufacturing Types Seamless: Includes hot rolled seamless and cold drawn seamless, diameters up to 24 inch normally.
ERW: Electric Resistance Welded, OD up to 24 inch.
DSAW/SAW: Double Sub-merged Arck Welding, substitute welding methods than ERW for larger diameter welded pipes.
LSAW: Longitudinal Sub-merged Arc Welding, also called JCOE pipe, OD up to 56 inch. JCOE is named by manufacturing processes with J Shape, C shape, O shape and cold expanding process to release the pipe strength during transformations.
SSAW / HSAW: Spiral Sub-merged Arc Welding, or Helical SAW, diameters up to 100 inch.
Applications
Oil and gas transmission pipe;
Petroleum and natural gas industries;
Low and medium pressure pipeline systems;
Sour services (Low Carbon, CEQ, and S) Nace pipe anti-corrosion for H2S environment;
On shore and off shore pipelines;

About Coating Type
FBE+3LPE
The anti corrosion coating can be used for ERW/LSAW/SSAW pipe,straight seam pipe,seamless steel pipe,etc. And the coated pipes are widely used in pipeline projects in the field of petroleum,chemical, natural gas,heating,sewage treatment,water, bridges,steel structures,piling and other marine water.
FBE anticorrosive epoxy powder:
FBE epoxy powder preservative structure:electrostatic spraying epoxy powder coating on the pipe surface,a film. The coating has a coating operation is simple,clean,good impact resistance and flexural properties of the coating, temperature resistance advantages.
2LPE/3LPE corrosion coating:
2PE/3PE corrosion structure: the steel surface electrostatic spraying epoxy powder and binder twine lateral lateral wound polyethylene coating,combined with three excellent performance,thereby significantly improving the overall quality of corrosion of the pipe. Resistant to chemical corrosion, cathodic stripping, resistance to mechanical damage performance. Three-layer polyethylene anti-corrosion (3LPE/3PE coating pipe)is currently at home and abroad buried pipe outside the main technicall system of anti-corrosion. Its anti-corrosion performance is good, low water absorption, high mechanical strength, in recent years in the domestic buried water, gas, oil pipeline on the access to a wider range of applications.
