Goodwin Steel Castings specialises in producing high integrity, pressure vessel castings from a few kilos to 18,000 kg in weight in carbon and low alloy steels, stainless steels, duplex stainless steels and super nickel alloys such as Hastelloy and Alloy 625.
To be globally competitive, Goodwin International buys its materials on a global basis from a small number of foundries and forges with which it has long term association. Goodwin has full-time in-country employees in the countries from which it sources to continually audit the quality of material sourced.
Goodwin International has a fully equipped machine shop covering some 14,100 m2 with 36 modern CNC machine tools.
Test & Inspection
The test facilities include six hydraulic hydrostatic test rigs, the largest of which has a 2500 tonne hydraulic ram, and two high pressure pneumatic test rigs capable of testing to 20000 psig (1,380 barg).
At Goodwin International's cryogenic test facility, cryogenic (-196°C) and low temperature (-50°C) testing is conducted in accordance with Shell's MESC SPE 77/200 specification or like procedure. Goodwin can accommodate most clients' testing regimes.
High Pressure Gas Testing
Goodwin has its own high pressure gas test facility where it can test valves in-house as large as 72” to pressures of 20000 psig / 1380barg.
With in-house grit blasting (ferrous and non-ferrous) and humidity controlled ovens, Goodwin has the in-house painting capability to meet a wide spectrum of customer specifications ranging from single coat systems to typical multi-coat epoxy and polyurethane systems for offshore environments.
