Description

DIN 2394-81 ST44-2 As-Welded and Sized Precision Carbon Steel Tubes

Carbon Steel ST 44-2 DIN 2394 Piping are predominantly used in the construction of the chemical plant, pressure vessels, pipework and for general mechanical engineering purposes.

This Standard applies to welded and sized precision steel tubes; and, in compliance with ISO/DIS 3306, those tube dimensions have been selected from the range of manufacture dimensions which are mainly used as design elements

If tubes with the tolerances and in accordance with the technical conditions of delivery of this Standard ard to be user as pipelines, the dimensions of DIN 2458 may, if necessary, be used. These tubes must e ordered according to quality grade C.
