PERT pipe production line

PERT Pipe Production Line 1. Purpose and Scope of Application This production line is mainly used for the production of PERT (heat-resistant polyethylene) pipes. This pipe is a non crosslinked polyethylene pipe that can be used for hot water. Some people also highlight its non crosslinked characteristics and call it high-temperature resistant non crosslinked polyethylene pipe

PERTpipe production line
1. Purpose and Scope of Application
This production line is mainly used for the production of PERT (heat-resistant polyethylene) pipes, which are non crosslinked polyethylene pipes that can be used for hot water. Some people also highlight their non crosslinked characteristics and call them "high-temperature resistant non crosslinked polyethylene pipes". Mainly used in industries such as plumbing and heating systems, central air conditioning piping systems, floor radiant heating systems, solar water heater systems, etc.
2. Equipment composition and characteristics
Our company's PERT pipe production line has a unique structure, high degree of automation, easy operation, and stable and reliable continuous production.
Production process: Raw materials → Vacuum feeding → Raw material drying → Single screw extruder → Spiral mold → Low temperature cooling sizing sleeve, high water level box → Immersion vacuum shaping box → Immersion cooling water tank → Immersion cooling water tank → Spray coding machine → Belt traction machine → Double station winding machine → Finished product inspection and packaging
Main features of the equipment:
Extrusion equipment: The single screw extruder adopts a slotted barrel and a new BM screw, with high screw speed, output, and plasticizing capacity.
Extrusion mold: Adopting a spiral diversion head, it has the characteristics of uniform discharge, convenient adjustment, and reduced extrusion weld marks. Through the improvement of the head, the situation of melt fracture during extrusion is effectively avoided, ensuring high surface smoothness of PE-RT pipes. Disc type sizing sleeves are used due to their low friction with the surface of the pipe, avoiding adhesion between the pipe and the sizing sleeve.
Vacuum shaping device: The total cooling length is 17 meters, including one vacuum sizing box and three cooling water tanks. The purpose of the cooling length configuration is to meet the cooling capacity required for producing 20x2.0mm pipes at a line speed of 15/min, while also taking into account the additional cooling required for the coils.
Traction machine: Two jaw belt type high-speed traction machine, using variable frequency stepless speed regulation to meet the requirements of traction stability in pipe production.
Dual station automatic winding machine: equipped with tension control and automatic adjustment of winding speed, and equipped with cable arrangement device.
There are multiple electrical control systems to choose from (such as PLC automation control system), with fast and stable production speed, simple and easy control operation.
