Spiral-welded A A A

Steel pipes – spiral-welded

The pipes are manufactured in line with the following standards: EN 10208-2, EN 10208-1, DIN 1626, DIN 17120, API Spec 5L i EN 10219 and PN-79/H74244.

Outer diameter of spiral-welded steel pipes manufactured by Izostal S.A. ranges from 323.9 mm to 1422 mm; the pipes are delivered with straight or bevelled end faces. Tightness test and automatic, non-destructive ultrasound and/or radiological test (the latter at the customer’s request) are carried out prior to delivery.

Upon arranging technical specification we deliver pipes of diameter and wall thickness values outside of the range specified in the abovementioned chart,  provided the desired diameter value is within the outer diameter range of 323.9 mm and 1422 mm.. Minimum length: 4 metres; maximum length: 14.2 metres.

The pipes are made of killed, unalloyed and low-alloy standard, quality or special steel, depending on the required mechanical and technical performance as well as the intended use.

The pipes are delivered in black, without the protective coating, externally coated with extrusion moulded three layer polyethylene coating, additionally coated externally with cement and internally coated with epoxy or cement coating, in line with the customer’s requirements.

Delivery of pipes with other anticorrosive protection requires earlier arrangements.
