Process Pipe & Tubes

Our range of austenitic duplex stainless and Nickel alloys provides material solutions across a diverse size range, supported by global production sites to offer our Customers both the economies of volume production or the flexibility to service breakdown requirements.

Piping

Our Nuclear pipes are manufactured for Class 1,2 & 3 Piping for Nuclear steam supply systems and non-nuclear island applications such as Nuclear fuel reprocessing.  We manufacture pipes with close dimensional tolerances, tight UT control, controlled surface finishes and a high degree of cleanliness.  

We work in close partnership with fabricators and designers. 

We collaborate closely with fittings manufacturers to supply them with raw material for their fittings manufacture.
