Superduplex welding
SDMS skill is the documented manufacturing of complex parts made of
special metals : superduplex, copper, glidcop, Inconel, titanium,
hastelloy, zirconium, zircalloy, aluminium alloys, nickel alloys.
Superdupex welding and alloys
SDMS regulary use all grades of stainless steel, nickel alloys, titanium,
hastelloy, duplex, superduplex and aluminium alloys.
Duplex and superduplex welding
For many years, SDMS works austenitic-ferritic stainless steels.
Strict procedures for the control of welding conditions allow to preserve
in the welded areas the properties of these steels about corrosion.
SDMS controls TIG, Electron Beams, Plasma, SMAW, MIG and SAW procedures.
The most usually thicknesses are between 4 and 30 millimeters.
SDMS manufacture various tanks, tubular exchangers, columns, separators,
etc...
The installations are usually subjected to severe inspections such
as french DRIRE, US FDA, german TÜV, swiss ASVIT, dutch STOOMWESEN.
