PE foam sheathing line

A new European project for the production of insulated water pipes for UNION, consisting in the production of foam sheaths for the covering of rigid copper or multilayer pipes with diameters from 16 to 32 mm and insulation wall thicknesses of 6/10/13 mm.

There is also a coating and embossing unit for the finished pipe, thus the production system includes two different processes that intersecting make the required product: twin screw extruders for the sheaths producing and single screw extruders for their coating, equipped with a series of distributors at 4 independent die heads for the extrusion of 2 or 4 sheaths a time.

The extruders are equipped also with a filtration system to allow the use of the recycled plastic materials.
