Temper Bead Procedure
This is one of Dynacorp’s foremost advantages – and it represents time and money savings for any asset owner with pressure vessels that need repair or modification.
Pressure vessel welding typically requires post-weld heat-treating. This costly step often makes it cost-prohibitive to salvage a used pressure vessel, especially a larger one, for re-use. That forces the asset owner to commission an even more expensive new build – then often wait months for delivery.
Dynacorp’s temper bead procedure can avoid all that. This ABSA-certified procedure comprises pre-heating the metal surrounding the area to be welded to 350° F.
