CNC manufacturing
Turned, milled, welded: we manufacture complex single parts and small batches from heat-resistant and stainless steels – exactly to your specification.
Pipe connections
Weld neck flanges in all common nominal sizes and pressure ratings – from stock or custom-made with individual drilling.
Piping
Forged fittings with threaded or socket-weld ends – caps, couplings and reducers for high-pressure lines, from stock or to drawing.
Welding fittings
Equal and reducing tees for branch connections in high-pressure piping – with socket-weld, threaded or butt-weld ends to standard or drawing.
H+G Stahl
We supply heat-resistant and special steels for power plants, refineries, chemical works and special piping. In our own plant we machine the material, build custom parts and valves, and deliver the goods to you ourselves.
