Problems with post-weld heat treatment of carbon steel pipes
Thread Content
Are there any thickness requirements for carbon steel pipes during post-weld heat treatment? What thickness of tube will prevent deformation during heat treatment? Thank you
Thin-walled steel pipes should not require heat treatment after welding, right?
There are thickness requirements, which must be met in accordance with the corresponding manufacturing standards and technical specifications
Only carbon steel pipes that reach a certain wall thickness or are under certain operating conditions require heat treatment
There are no specific thickness requirements; it is subject to the relevant manufacturing standards and drawing specifications, with heat treatment being carried out together with the equipment.
It is generally heat-treated together with the equipment; rarely are the fittings required to be heat-treated separately. Deformation generally does not occur
For the pipes in the pipeline where the medium contains hydrogen sulfide, is heat treatment necessary?
No special mention is made of the need for separate heat treatment for steel pipes; usually, they are heat-treated along with the equipment (if the equipment requires heat treatment)
