PERT pipe, produced by the raised temperature resistant polyethylene of raw material, transparent for all, is the most common under floor heating pipe at present.

Pipe inner wall is smooth, it can reduce the blocking phenomena by the residuum in the water, has its own advantages of good flexibility, easy to install and carry, resistance to low temperature and forst crack and service life up to 50 years.

There are mainly three different speed models for PERT pipe extrusion lines. The stable production speed is up to 50m/min.

Features of Pipe Production Line

1) High efficient five section type screw and barrel, to ensure fast plasticizing & dispersion effcct.

2) Gravimetric material feeding system is to control material feeding according to pipe parameter & line production speed, to get high qualified pipe with constant weight per meter. It's also have benefits of shortening start-up time, saving raw material and simplifying operation.

3) Spiral Pressure storage die head effectively overcomes the instantaneous fluctuation of extrusion pressure, realizing high speed pipe extrusion with stable pressure.

4) vacuum and calibrating system is futher optimized based on our previous high speed pipe extrusion line technology; with better structure calibrating and cooling become more effective.

5) Servo type traversing device of winder machine, and with ultrasonic tension control device, to auto adjust widing speed matching with line speed.

6) SIEMENS programable PLC control system with big color touch creen. Having multi-point close-loop control and sysnc system. Remote control system is also applied for after sales technology support.
