Arc Energy Resources has recently shipped a selection of stainless steel clad flanges to Belgium-based Icarus, which specialises in the manufacture of bespoke flanges, valves and pipe fittings for the oil and gas, petrochemical and nuclear industries. Arc Energy was able to offer a fast turnaround on three orders for conventional low-temperature-tested carbon steel flanges clad with 316L stainless steel using its advanced welding processes. For the most recent order, three large flanges were delivered to Arc Energy’s Gloucestershire factory and pre-machined to accept the cladding, which was then applied in two layers to ensure that the full chemical requirements of 316L were met. The flanges were then finish machined and NDT inspected. For use in the oil and gas production industry, the flanges – ranging from 16 to 36in and totalling 19 in all – form part of a piping system that is subjected to a number of corrosive elements depending on the refinement stage including C02, H2S and chlorides found in marine environments.
