Offshore oil and gas platform pipework

Sectors

Flanges, fittings and pipe
for oil and gas

Pressure-rated carbon, low-temperature and stainless material for upstream, midstream and downstream pipework, fully certified and traceable.

Built on North Sea experience

Midsteel's experience dates back to the earliest North Sea oil discoveries, and oil and gas remains at the core of what we do. We understand the specifications, inspection requirements and deadlines that come with hydrocarbon projects, from new-build fabrication to shutdown maintenance.

We stock ASME B16.5 flanges up to Class 2500, SA350 LF2 low-temperature forgings, SA234 WPB and stainless butt weld fittings, and SA106 Grade B and stainless pipe. When a line needs isolating, we machine spectacle blinds, spades and spacers in-house.
