3PE /Pete Anticorrosion Steel Pipe Coating Machine

Product description

2PE,3PE and FBE Epoxy coated steel pipe is widely used in pipeline systems for the transmission of oil, gas, water and other fluids. They have high resistance to corrosive from chemicals, moisture, harmful environment, etc.
3 layer PE anti-corrosion coating consists of first FBE coating, middle adhesive layer and outer polyethylene layer.

Bend Pipe 3PE Coating Equipment is used to bend pipe 3PE coating, it consists of bend pipe transportation equipment, bend pipe blasting machine, bend pipe intermediate frequency heating, bend pipe 3PE coating, bend pipe spraying cooling

First layer is Fusion bonded epoxy layer (FBE> 100µm), the second layer is adhesive (AD) 170 ~ 250µm, and the third layer is polyethylene (PE) stripe 2.5 ~ 3.7mm.
3PE steel coating pipe has the features of high mechanical strength, excellent electrical insulation performance, Process accuracy and environmental friendliness.

Application

The three-layer HDPE stripe winding process, with epoxy powder coating as bottom layer and binding adhesive as second layer, is the widely used technique in steel pipe anti-corrosion all over the world. The anti-corrosion steel pipe are applied in oil, gas and water supply pipelines.

Three-Layer structure of 3PE anti-corrosion pipe
The three-layer PE anti-corrosion structure includes fusion bonded epoxy-powder bottom layer, polymer adhesive middle layer and polyethylene outside layer. The epoxy powder is a kind of thermosetting nontoxic coating, forming the high molecular weight cross-linking structure coating after solidifying, featuring good chemical anti-corrosion and high mechanical properties. Function of epoxy layer is to form continuous coating and to provide the steel tube surface with good chemical resistance and cathodic disbanding resistance. The function of polymer adhesive is to agglutinate the epoxy layer and the polyethylene outside layer, which unites all three layers together. The polyethylene layer protects the pipe from abrasion, bump and water.
