3PE&3PP Anti-corrosion Pipe basic infomation

3PE&3PP Anti-corrosion Pipe
 
Standard:
External coating: NFA49-710, DIN30670, CAN CSA21, CAN CSA 20, SY/T 0413, SY/T 0315 and other country’s external anti-corrosion standards.
Internal coating: NFA49-709, APIRP5L2, SY/T0457 and other country’s internal anti-corrosion standards

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.
 
Outer Corrosion Protection of Steel Pipes:
1, Single-layer FBE Coating(FBE)
Characterized by excellent corrosion-proof performance, insulativity 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 of normal type: 300~400um; strengthen type: 400~500um.
2
Two-layer FBE Coating(2FBE)
Two-layer epoxy powder coating is a compound coating structure composed of anticorrosive epoxy powder floor layer and mechanical damage resistant epoxy powder surface layer. There are normal type and strengthen type. Thickness of total Thickness of Normal Type: ≥620um; Total Thickness of Strengthen Type: ≥800um.
3
Two-layer PE/PP Coating(2PE/2PP)
Two-layer PE/PP coating is characterized by excellent corrosion-proof performance, insulativity, relatively long service life and mechanical damage resistance. There are normal type and strengthen type. The thickness varies with the specification shift of steel pipe: Thickness Min. of Normal Type: 1.8mm;Thickness Min. of Strengthen Type:2.5mm.
4
Three-layer PE/3PP Coating(3PE/3PP)
Three-layer PE/PP coating is characterized by excellent corrosion-proof performance, insulativity, relatively long service life and mechanical damage resistance. It is widely used in coating for all kinds of major pipeline engineering. There are normal type and strengthen 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.
 
Inner Corrosion Protection of Steel Pipes:
We offer inside corrosion protection for DN 100~700mm steel pipes. We coat inner wall of treated steel pipe with red oxide anticorrosive paint, bicomponent liquid epoxy paint or other paint designated by clients by means of Centrifugal coating.
