Stainless and carbon
steel pipe fittings

Butt weld, forged socket weld and screwed, and low-pressure BSP fittings, stocked in the grades and schedules that match our pipe and flanges.

A UK pipe fittings stockist for every joint in the line

Midsteel stocks a comprehensive range of steel pipe fittings: butt weld elbows, tees, reducers and caps to ASME B16.9; forged socket weld and screwed fittings in Class 3000 and 6000 to ASME B16.11 and BS 3799; and 316 stainless BSP fittings for low-pressure threaded work.

All are available in stainless steel, and butt weld and forged fittings are also stocked in carbon steel. They match the schedules and grades of our pipe and flanges, so a complete system can be supplied on one order with one set of certificates.

Butt weld, socket weld or screwed?

Butt weld fittings are welded directly to the pipe end and give a smooth bore and full-strength joint. They are the standard choice for process lines from about 2" upwards and for any service that needs to be radiographed. Forged socket weld fittings are used on small-bore, higher-pressure lines where the pipe slips into a socket and is fillet welded. Screwed fittings allow assembly without welding.

Low-pressure BSP fittings are cast rather than forged, and are rated for 150lb service. They are ideal for instrument, water, air and utility lines where a threaded joint is quicker and cheaper.

A long radius elbow has a centreline radius of 1.5 times the nominal pipe size and gives a smoother flow with less pressure drop. A short radius elbow has a radius equal to the nominal size and is used where space is tight.
It is the pressure class of forged fittings to ASME B16.11. The class is matched to the pipe schedule the fitting will be welded or screwed to: Class 3000 is typically paired with Schedule 80 pipe and Class 6000 with Schedule 160.
Yes. Our forged screwed fittings are available with NPT or BSPT threads. Our low-pressure BSP fittings have BSPP female and BSPT male threads.
