Thanks to our own stock and excellent relationships with suppliers (including forges and rolling mills) we offer maximum reliability, which translates into constant quality and very speedy delivery.

Orifice flanges
From stock we offer a wide choice of orifice flanges (ASME/ANSI B 16.36), in both carbon steel (ASTM A 105 N – ASTM A 350 LF 2) and stainless steel varieties. On request we can also deliver special types, e.g. with weld-on nipples. Measuring plates are available according to specification, in any design.

Custom design
Our specialty is manufacturing custom made products. For your every specific requirement and design we will supply the right materials, and take care of flawless processing as well. Our ample stock of certified materials allows us to quickly come up with a perfect answer to almost any question. Before delivery, products are thoroughly tested and checked in accordance with prescribed standards. For you this means the perfect assurance of quality and in-time delivery.

Our range of fittings includes every conceivable variety, such as ANSI B 16.9 – ANSI B 16.11, 3000-6000-9000 lbs, DIN and BS. Bends, T-joints, caps, couplings, unions, concentric/eccentric swage nipples and reducing connectors are almost always available from stock. Products according to different standards and with other wall thicknesses can  easily be taken into production, with the option of including magnetic and penetrant inspection.
