Collars and backing flanges
Metric stainless systems are often joined with a pressed collar welded to the tube and a loose backing flange behind it. Only the collar is wetted, so the backing flange can be a lower-cost coated or galvanised mild steel ring. It rotates freely, which makes bolt-hole alignment on site much easier.
We stock backing flanges in stainless steel and in coated and galvanised mild steel, in PN10, PN16 and 150lb drillings, in both reduced and full thickness.
EN 10253-3 or EN 10253-4?
Both cover stainless butt welding fittings. EN 10253-4 fittings carry specific inspection and non-destructive testing requirements, so specify them where your system is covered by pressure equipment rules.
