Sleeve-technology steel pipe coating unit

摘要

Bandera, Italy, has completed the production of the latest version of its extrusion platform for the coating of steel pipes with sleeve technology, for shipment to a Russian coater. The system is suitable for coating pipes up to 0 21", and includes an extrusion platform supporting two extruders. One TR160 series machine will be used for PE extrusion, with the other TR85 series unit used for tie resin - meaning a total output of 1,250kg/h. The extruders are equipped with bimetallic barrels, the extrusion screws are coated with a special wear-resistant and antifriction alloy, and AC motors with 'direct torque control' vectorial inverters are used.
