The spiral reinforced PVC hose extrusion line is mainly composed of two extruders, spiral forming unit, water cooling tank, haul off, coiler etc. This hose is also called PVC suction hose, which takes the advantages of extrusion resistance, corrosion resistance, negative pressure resistance, anti-bending, good liquidity.So it is suitable to convey gas, liquid and powder, widely used in industry, agriculture, constructionn and irrigation, etc.

Features:

1. The extrusion screws adopt big L/D to ensure plasticization quality, higher transparency the finished hoses.
2、The spiral forming unit utilizes the variable frequency drive to make the winding speed consistent, easy to adjust. 
3、The unique design of the combination type die head allows for excellent coupling of spiral reinforcement to the pvc helix.
