PRECISE STEEL PIPES, SEAMLESSLY DRAWN (PN-EN 10305-1)

Manufacturing and purpose
Cold drawn seamless pipes are made with diameters from 4 - 120 mm and wall thicknesses up to 12.5 mm. They can also be produced with heat treatment - normalizing or annealing.
The advantage is high accuracy of workmanship, good surface quality and they are widely used in the engineering and automotive industries.

Steel grades used
non-alloy quality steels E215, E235, E355, E255, E410, 26Mn5, 10S10, 15S10, 18S10, 37S10,
special non-alloy steels C35E and C45E, special alloy steels 26Mo2, 25CrMo4 and 42CrMo4

Dimensions
Outside diameter: 4 to 120 mm
Wall thickness up to: 12.5 mm
Length: 3 to 7 m

Research and requirements
Tests: chemical analysis, tensile test, dimension check, visual check.

Straightness: <0.0015 pipe length (less than 3mm per meter of pipe).
Tightness: pipes should be subjected to a water test (7Mpa) or electromagnetic testing.
