PERT pipe, produced by the raised temperature resistant polyethylene of raw material, transparent for all, is the moset 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 frost crack and service lif up to 50 years.

This pipe extrusion line is mainly used for the production of PERT pipe at high speed, which stable speed can reach to more than 40m/min.

Technical Data of Pipe Production Line:

Line Model	Screw Diameter	L/D	Production Speed	Nominal Power
SJ-75	Ф75mm	36:1	50m/min	155KW
SJ-60	Ф60mm	36:1	35m/min	104KW
SJ-80	Ф80mm	33:1	25m/min	112KW
SJ-65	Ф65mm	33:1	15m/min	76KW

Features of Pipe Production Line:

◆ High efficient five section type screw and barrel, to ensure fast plasticizing & dispersion effect.

◆ 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 other benefits, such as shortening start-up time, saving raw material, simplifying operation.

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

◆ Vacuum and calibrating system is further optimized based on our previous high speed pipe extrusion line technology; with better structure the pipe calibrating and cooling has become more effective.

◆ Fully automatic pipe winder; The whole process from reel changing to pipe cutting and winding is automatic. SIMENS PLC controlled separately and can be synced with line production speed.

◆ SIMENS programmable PLC control with big color touch screen. Having multi-point close-loop control and synchronous system, which ensure the easy and reliable operation of the line.
