1. Single screw extruder especially used for polyolefine material possess effective plasticizing effect and high extrusion speed.
2. The special detached type compounding screw an die head with spiral structure & reasonable channel are applicable to produce pipes with smooth inside and outside face.
3. Unique calibration and cooling mode is capable of producing pipe with diameter from φ50 to φ200mm, production speed is up to 0.4~1.5m/min.
4. All kind of polyolefine material, multi-layers spiral strengthening pipe can be co-extruded,  recycled materials can be used in production;
5. Optimum spiral copper sizing sleeve, its entrance carrying pre -cooling and powerful vacuum device to suit for high speed extruding pipe.
Stainless steel cooling water trough is three-dimensional regulation, longitudinal moved by motor.
6. High efficient cooling comes from peculiar spraying nozzle and high efficiency water pump.
