3 Layer PE Steel Pipe Anticorrosion Coating line

• The cladding type

Two sets of extruder are placed on live platform which can drive die go up and down. There are two guide rails which can help adjust the distance between die and pipes. Two sets of dies can move up and down according to different needs. Pipes can go directly through the die and AD & PE can wrap on the pipes uniformly.This can not only help save material, but also prevent roller from wearing.

• Side type

In this type, die is side blew pipes and the adhesive and polyethylene press rollers are directly blew pipes. The AD extruder and PE extruder are placed vertically with production line. They can move back and forward (AD extruder can move laterally) to adjust the angle between coating layer and steel pipes

• Upper type

Two sets of extruder are placed on one side of production line. The extruder is vertical to production line. The extruders are placed on live platform and die and extruder can move up and down. Pressing roller and guide roller are separately placed on a live scaffold. This can help easily adjusting the extrusion and wrapping equipment according to different pipes and also adjusting the width of coating layer. It can not only ensure the uniformity of PE, but also save raw material.

Since the space under pipes is unlimited, pipe carrier can be installed under pipes. As a result, there is no need to use pipe connecting device. In the meanwhile, the cutting of rudder at the end of pipes can be achieved.

• Co-extrusion

Steel pipe water spraying equipment

The water cooling system is used to cool heated piped rapidly to the temperature of *0℃**0℃, to protect its anticorrosion layer and protection layer.

Water cooling system consists of water cooling room, water cooling tower, self-prime pump, centrifugal pump, pipeline, etc. There is a back water pond near cooling room

Cutback machine

This device is used to remove pipe-end coating layer and then form a groove whose angle is below *0°, in order to joint easily.
