Maxflux SAF-7S is a high speed welding acidic agglomerated flux for spiral pipe welding. The flux is suitable for single & multi-pass welding with single wire & multi-wire applications in both AC & DC polarity. Slag detachability is good and deposited weld metal is of radiographic quality.
Maxflux SAF-7S is suited for fabrication and welding of spiral pipes, smaller
diameter pipes (internal and external), penstock pipelines, wind mill towers,
pressure vessels, girder, earthmoving equipment, structures of off-shore
platforms, etc.
Re-dry the flux at 300-350°C for two hours before use.
