3LPE Pipe

Threr are three layers in 3LPE coated API 5L X46MS Pipe.

Layer 1: A corrosion proective layer. Mainly is fusion bonded expoxy, it will bonding wiht the steel surface.

Layer 2: Copolymer adhesive layer. Copolymer adhesive is a maleic anhydride grafed polyethylene compound.

Layer 3: This layer is for physical protection and consists of polyethylene.

API 5L X46MS Pipe usually provided with 3LPE coating.

Carbon Steel Welded Pipe Quality Control

Surface 

Clear  Marking and fin appearance. The marking should conver item, diameter, thickness, length, material, coating and heat No.

Dimension

Measure the diameter, thickness and lenght of API 5L X46 PSL2 pipes, make sure they are in tolerance.

Material

Test if the chemical composition and mechanical properties are qualified.

• Hydrostatic test to ensure it’s leak-proof.
• Bend test: no cracks or opening of the weld shall occur.
• Flattening test

Certificate

• CE, ISO, TEST REPORT, Stamp mill test certificate

Third Party Ispection

BV, SGS, LR, DNV, ABS
