Extrusion line for corrugated pipes with integrated tube
Ø 16 - 125 mm, 50 - 340 kg/h | EC 50, EC 50+, EC 130
Corelco SAS
Corelco developed in 1996 a range of extrusion line for the production of pre-assembled sheathing corrugated pipes, in order to answer to a growing demand.
PROCESS
Rather than inserting the smooth pipe after extruding the corrugated pipe, the Corelco's process consists of extruding the corrugated pipe around the smooth pipe, thereby producing a ready-to-use product. We can produce the pre-assembled sheathing in two ways :
-in line process: the pre-assembled line is positioned after the smooth pipe extrusion.
-resumption process: the smooth pipe, which is produced in big coils (500m), is uncoiled and introduced in the pre-assembled sheathing line, coils are connected together with steel connectors inserted by a connection unit to work with a continuous length. At coiling time steel connector is detected and ejected of the finished product.
THE EXTRUSION AND THE TWIN PRE-ASSEMBLED SHEATING
The twin pre-assembled sheathing is principally used for the heating and sanitary network, the radiator's connection.
This twin pre-assembled sheathing permits a big saving time for the users, uncoiling only one coil instead of two before.
TWIN EXTRUSION PROCESS
The extrusion of the twin pipe requires a special die head to bond them together by means of a discontinuous longitudinal segment of material.
This makes it possible to split them, if required, and provides a ready-to-use product.
TWIN PRE-ASSEMBLED SHEATING PROCESS
Identical to single pre-assembled sheathing process, equipments are adapted to twin process.
