Welded steel pipes

HOT CLOSED SECTIONS MADE OF NON-ALLOY AND FINE-GRAINED STRUCTURAL STEEL WITH SEAM (STANDARD PN-EN 10210-1,2)

Manufacturing and purpose
Made of welded sections with additional normalization or hot reduction. Made of unalloyed and fine-grained structural steels, they are suitable for the construction of various types of steel structures, houses, and various types of machinery and equipment.
Due to their durability and simple structure, they can be used to make durable structures at relatively low costs. Examples of applications include, but are not limited to, frame structures for buildings, machines or vehicles. They are also used in the construction of bridges, masts and other structures.

Steel grades used
for unalloyed steels: S235JRH, S275JOH, S275J2H, S355JOH, S355J2H
for fine grain steels: S275NH, S275NLH, S355NH, S355NLH, S460NH, S460NLH

Dimensions
Outside diameter: 21.3mm to 1210mm
Wall thickness up to: 50 mm
Length: 6 - 15 m, special lengths up to 24 m
Research and requirements
Straightness: 0.2%: full length for round tubes and 0.4% full length and locally.
For these pipes, leakage tests are not required, however, several other required tests should be carried out, including: a smelting test, a tensile test, an impact test for pipes with a wall thickness above 6mm and several others.
