Liquid Transmission 457.2MM High Frequency Welded Pipe

Liquid Transmission 457.2MM High Frequency Welded Pipe

We use 3LPE coated steel pipe in transferring natural gas, crude oil and refined oil product over long distances. It also can be used in the urban fuel gas piping system, storage tanks, and groove piping system. 3PE’s main purpose is protecting pipes which used in electricity and communication industries and water piping systems.

Layers of 3PE coated steel pipe

Just as its name implies, 3PE coating including 3 Layers.

The first layer of 3PE coating:

Fusion bonded epoxy, which thickness is larger than 100μm. ( Thickness of FBE coated ＞100μm )

The second layer of 3PE coating:

Adhesive layer. It is binding epoxy and PE layers. ( Thickness of second layer: 170~250μm)

The third layer of 3PE coating:

PE layers. Thickness is from 2.5 mm to 3.7 mm. It is polyethylene which has advantages to anti-water, electrical resistance, and anti mechanical damage. It is a very important layer.

From the layers of 3PE, you will find that 3PE coated steel pipe integrated with the advantages of FBE and PE. It is more and more widely used in the buried pipeline’s transporting of water, gas, and oil. And it also means if one factory has 3PE coated steel pipe manufacturing equipment, they can do FBE coating pipes as well.
