Product Description 1.Mechanical Properity and Chemical Composition
2.Anti-Corrosion Processing About Pipe Line 3PE/PP 2.1 Standard 2.1.1 External coating Refer to:NF A49-710,DIN30670,CAN CSA20,SY/T0413,SY/T0315 and other country's external anti-xorrosion standards. 2.1.2 Inernal coating Refer to :NF A49-709,API RP 5L2,SY/T0457 and other country's internal anti-corrosion standards. 2.2 Application The external coating is mainly used for anti-corrosion protection for liquid pipes before burying,and internal drag-reducing coating is mainly used to reduce the investment and maintenance costs. 2.3 Outer Corrosion Protection of Steel Pipes: 2.3.1 (FBE) Single-layer FBE Coating Characterized by excellent corrosion-proof performance,insulatibity and relatively long service life,epoxy powder coating is one of the most advanced outer anticorrosive coating of pipeline.There are normal type and strengthened type.Thickness:normal type:300-400 μm;strengthened type:400-500 μm. 2.3.2 (2FBE) Two-layer FBE Coating: Two-layer epoxy powder coating is a compound coating structure composed of anticorrosive epoxy powder of floor layer and mechanical damage resistant epoxy powder surface layer.There are normal type and strengthened type. Thickness:Total Thickness of Normal Type ≥620μm;Total Thickness of Strengthened type: ≥800μm. 2.3.3(2PE/2PP) Two-layer PE/PP Coating: Two-layer PE/PP coating is charecterized by excellent corrosion-poof performance,insulability,relatively long service life and mechanical damage resistance. There are normal type and strengthened type. The thickness varies with the specification shift of Steel Pipe
:Thickness Min of Normal Type:1.8mm;Thickness Min of Strengthened type:2.5mm. 2.3.4 (3PE/3PP) Three-layer PE/3PP Coating: Three-layer PE/PP coating is characterized by excellent corrosion-proof performance,insulatibity,relatively long service life and mechanical damage resistance.It is widely used in coating for all kinds of major pipeline engineering. Ther are normal type abd strengthened type.The thickness varies with the specification shift of steel pipe:Thickness Min.of Normal Type:1.8mm; Thickness Min of Strengthened type:2.5mm. 2.4 Inner Corrosion Protection of Steel Pipe: We offer inside corrosion protection for DN100-700MM steel pipes.We coat inner wall of treated steel pipe with red oxide anticorrosive paint,bicomponent liquid epoxy paint or other paint designated by means of Centrifugal coating. 3.Product Show

A:The near standard of API 5L PSL1 in China is GB/T9711.1 Q: What's the difference between psl1 and psl2? A: PSL is "Product Specification Level".In case of PSL-1 impact testing is not mandatory and in case of PSL2 impact testing at 0 deg C is mandatory.There is a difference in Chemical composition requirements between PSL1 and PSL2.In case of PSL1 Yield Stress and UTS demands "min" value whereas in case of PSL2 there is a range of "min" and "max" for YS and UTS. 7.
