JINHU GROUP JHE 45-33 extrusion line was manufactured in 2017 in China
by Shanghai Jinhu Pipe Equipment Co., LTD. The line is currently
configured to produce innovative polyethylene (PE) pipes with a
diameter of 40 mm, designed for ground heat exchangers. The pipes
feature a star-shaped cross-section, which, compared to conventional
round pipes, provides a larger heat exchange surface area. By
replacing the extrusion head and calibrator, the JINHU GROUP extrusion
line can also produce round pipes and profiles.
The JINHU GROUP JHE 45-33 extrusion line comprises the following
components:
– JHE 45-33 single-screw extruder for polyethylene (PE)
– extrusion head for pipes with a star-shaped cross-section fi 40
– mould for converting the pipe cross-section from star-shaped fi 40
to round 3/4 inch
– PN 110 automatic circular sawing machine
– NOWATECH UHRB-315/400 butt fusion welding machine
– WChPd 110 vacuum tank
– caterpillar haul-off
– GAMART dual-drum winder
– automatic granulate feeder
The pipe manufacturing process begins with the plasticisation of PE
granulate in a single-screw extruder. The material is then fed into
the extrusion head, which gives the pipe its characteristic
star-shaped cross-section. The formed pipe then passes through a
calibrator that gives it the required dimensions, after which it is
cooled and conveyed by a caterpillar haul-off. Once the process is
complete, the pipe can be cut to specified lengths or wound into
coils, facilitating storage and transport.
