UPVC foam-core pipe extrusion line

UPVC foam-core pipe extrusion line

The extrusion system of PVC foam core pipes comprises of main extruder used to produce the middle foam core/compact layer and a co-extruder to produce the inner and outer skin layers. The thickness of the inner and outer layers in relation to the central pipes layer is controlled through extruder output during operation. A combined dosing and horizontal feeding unit is used to add the foaming agent.  

The heart of the foam core pipe line is the Feed-block. The feed-block designed by our company enables the production of pipes up to max. 630 mm diameter. 

We offer PVC foam core pipe machine for production of 3-layer PVC-pipes. Cost savings in production of material savings by an foam core is the vital argument to compete with compact pipes in non-pressure applications.

The use of foam core pipes for low-pressure applications, such as sewage, drain pipes and cable ducts has seen tremendous growth over the past years. Currently pipe diameters of 32 mm to 630 mm are on the market.
