Double Wall Pertol Pipe Production Line

Multilayer Petrol Pipe Making Machine

Below pipe extrusion machine is used to produce double wall petrol pipe system, primary pipe and secondary containment pipe.

Firstly one pipe production line is to extrude that primary pipe, with a three layer sturcture (EVOH-ADHESIVE+HDPE). Three extruders and one three layer coextrusion die head are equipped.

The second pipe production line is to extruder that secondary containment pipe.

TECHNICAL DATA

Features of Pipe Production Line

1) 3 layer HDPE/EVOH pipe machine and 2 layer PE co-extrusion machine are combined together for this speical oil pipe making, based on the technology accumulation of thousand of multi-layer pipe extrusion technology. It have achieve the sync control and stable reliable performance.

2) High efficiency extruder with special designed five section screw & barrel ensures the rapid material dispersion and stable extrusion at high speed.

3) Unique three layer/two layer co-extrusion technology makes melt material maintain a stable flow to obtain good quality; and more innovative technology is adopted to reduce mold cavity pressure, to reduce that machine energy consumption.

4) Primary pipe extruder, secondary containment pipe extruder and haul-off machine are sync controlled by PLC system, achieving that zero-erro communcation between machines. One touch type speed changing function eliminate many operating obstacles, which has greatly reduced that unqualified pipe rate compared with other similar products.

4) SIEMENS PLC system to realize many intelligent operations, such as multi-machine linkage, separate machine control, fault diagnosis, remote control etc. At same time, advanced on line monitoring and control technologies, such as servo tracking technology, static digital filter technology, etc., are used to ensure plasticizing quality and produced pipe accuracy under high speed extrusion.
