Project Description

£2.2m Project for Supply of Flanges, Fittings, Bolting & Gaskets

W Maass (UK) Limited have recently achieved on-time completion for design and supply of Pipeline Flanges, Fittings, Bolting and Gaskets to a sub-sea gas development in the Mediterranean.

The supply included Carbon Steel ASME & API flanges in A694 F65 High Yield material, with Corrosion Resistant Inconel 625 Cladding, applied and finish machined to each flange Ring Groove. A wide variety of flange sizes and dimensional specifications covered including ASME B16.5, ASME B16.47 Series ‘A’ and API 6A.

Pre-manufacture in-house ASME VIII Design Calculations and F.E.A (Finite Element Analysis) work was carried out to verify flanges and fittings against project specific design data, and to determine maximum bending moment capacity of each joint.

Sizes ranging from 2” up to 32”, with be-spoke designed 32” 1500 lb ASME Weld Neck, Swivel and Blind flanges, and modified API 10,000 PSI Type flanges.

The fittings included standard and special Barred Tee / Tee and Elbows, some with increased body thickness for reinforcement to withstand the requirements of external loads analysed prior to manufacture by FEA. Sizes ranging from 8” up to 32”, with up to 70 mm thickness at strategic sections of the design.

To accompany the Flanges and Fittings, were additional ancillary equipment of ASTM A320 L43 & L7 Stud-bolts, along with corresponding ASTM A194 2H Nuts, sizes supplied up to 3.1/2” Diameter at 1075 mm Long, along with Inconel 625 and Soft Iron Gaskets.
