Process
The polyethylene core tube has been produced firstly. Then the pipe will go through the steel wire winding unit to the outside layer extruders. Steel wire bobbins are installed in two round plate, the plate rotate one in clockwise and the other in opposite direction. So the wire will wrap on the core tube as a steel mesh. The second extruder Steel wire (mesh) reinforced layer Core pipe layer (PE) Outer pipe layer (PE) Adhesive bonding layer coats the adhesive resin on steel for binding of steel and plastic. And then the outer
polyethylene layer will cover all steel mesh and core tube to make a finished composite pipe. Reinforcement The meshed steel wire located in the middle layer to be the reinforcement. This wire
is a kind of high sthrength steel wire which can provide the excellent pressure against
property.
Steel wire, fiberglass, polyester fiber or other kinds of high stiffness fiber could be
used as the medial reinforcement on the polyethylene pipe. With these strengthening
materials, the working pressure resistance of the composite pipe is obviously raised
compared with the same wall thickness normal PE pipe.
