Oakley Steel specialises in supplying pressure vessel quality plate resistant to hydrogen induced cracking to the oil and gas industry.
Our customers are mostly fabricators building systems and subsystems for oil rigs, refineries and other installations (such as pumping stations). Many design to Section VIII of the ASME Boiler Pressure Vessel Code which means our focus on ASME grades (SA516 and SA387) makes purchasing a little bit easier for procurement engineers.
Boiler plate from Oakley Steel is used in a wide range of pressure vessel applications. Some examples include: amine strippers, splitting columns, seperators, dearators, coalescers and glycol contactors. As well as pressure vessels plate has also been used in flare stacks and heat exchanger shells. Other plates have been formed into components on process skids including – regeneration skids, fuel gas skids and reboiler skids.
There are two areas of particular importance for this market. Firstly there is the full traceability that we provide with each plate helping our customers meet their quality and safety assurance requirements.
Secondly there are various corrosive effects related to the processing of oil and gas under high pressures. Sulphide stress cracking and hydrogen induced cracking are two examples and we are able to supply steel that when combined with an appropriate design and maintenance strategy can help mitigate these types of corrosion.
Our most popular product is ASME SA516 with HIC resistance. This is according to
NACE MR0175/ISO15156 and EN10028–2:2003 (Annex D).
We also offer ASME SA516 to NACE, giving improved hardness, and various chrome molybdenum grades, for high temperature use, certified as A387, but dual certification is possible.
