Composite weld-neck and composite slip-on flanges are made up from two components, an inner Flange(welding collar) in Al-Brass, Cu-Ni 90/10, Cu-Ni 70/30 and an outer flange in carbon steel.Composite blind flanges are made up from a carbon steel blind flange with a welded-on, and machined disc in Al-Brass, Cu-Ni 90/10 or Cu-Ni 70/30.
Solid Flanges
Solid flanges in Al-brass, Leaded yellow brass, Cu-Ni 90/10 or Cu-Ni 70/30 are produced from bar by hot forging and machining, solid flanges in bronze are produced by casting and machining.
Solid Silver-Brazing Flanges
Solid silver brazing flanges incorporate integral silver-brazing alloy rings and under normal circumstances there is generally no need to socket feed with additional brazing alloy. The silver brazing alloy to AWS A5, 8-BAG1, BAG7, JIS E3261 BAG1, BAG7 or BS1845 AG1, AG7.
Product Range
Composite and solid flanges are available in standard sizes machining those of the relevant pipe and butt welding fittings.Non-standard size flanges are produced to certain minimum quantity limitations
