UPI manufactures solid wall Polyethylene and Polypropylene Pressure pipes using the most up-to-date extrusion machinery supported by technologically advanced automation systems and ultrasound thickness controls.

The production range is from 10mm to 2000mm outside diameter (OD) with a pressure range from 3.2 bar (45 psi) to 25 bar (360 psi), and higher for special circumstances.

The standard lengths of the pipes are 12, 18 and 24 meters. However, we can supply any length on customer request. Small diameter pipes from 16mm to 110mm can be supplied in coils from 100 to 500 meters.

Pipes with special diameters and thickness can be manufactured for different uses such as re-lining of oil pipes and industrial application.

Our pipe production is according to the international standards ISO 4427 and ISO 4437.
