Elbows, tees, reducers and caps: The rff stock programme covers all normal types in different material grades. However, if required we can also supply you with specially processed parts at short notice.

When it comes to pipes, flanges, elbows and butt weld fittings as well as pipe equipment, we ensure strong connections. Welcome to the world of rff.
