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.
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.
The pipe coating line meets the requirements of producing the steel pipe with coating which meets international standards DIN30670-1991,CAN/ Z245.21-2010,ISO21809-1-2009 SY/T 0413-2002, GB/T23257-2009,GOST 9.602-2016, GOST R 51164-98, GOST31448, GOST31445
The coating line mainly consists of the following units:
-steel pipe conveyor system
-shot/sand blasting system
-dust collector system
-pipe induction heating system
-epoxy powder spraying system
-PE&Adhesive coating system
-water cooling system
-pipe end cutting system
-hydraulic and pneumatic system
-testing system
-electronic control system
