DIN 1626 Spiral steel pipe,DIN 1628 welded pipe, DIN 1615 spiral welded steel pipes
Using of Sprial steel pipes
DIN 1626 Spiral welded steel pipelines, containers and apparatuses for the highest operational temperatures of 330°C and also the highest operational stress of 6.four MPa (based on diameter and wall thickness).
DIN 1628 Spiral welded steel pipelines, containers and apparatuses for the highest operational temperatures of 320°C and the highest permitted operational stress limitless.
DIN 1615 Spiral welded steel without any particular needs.
Input material for sprial steel pipes production is wide, hot rolled steel strip produced under thermally controlled rolling and cooling conditions with assured weldability.
