Pipe

Overview

Pipe in five material families

We supply seamless and welded pipe and tube across five material families, from commercially pure copper through to high nickel alloys. Marine grade aluminium is stocked for shipbuilding and offshore work.

Sizes, schedules, lengths and end finish are confirmed against each enquiry.
