Longitudinally Welded Steel Pipes

Longitudinally welded steel pipes are used in various industrial projects, such as the construction of drinking water transport networks, heating installations and technological installations.

To ensure their quality, they are subject to non-destructive test processes. Upon request, the longitudinally welded steel pipes can be provided with protection, using polyethylene insulation or epoxy paint.

Diameter: 33,7 - 1625,6 mm
Thickness: 2,5 - 17,5 mm
Length: 6,0 - 12 m
