Diamould connectors, developed and manufactured by OneSubsea, are capable of wet-mate and de-mate cycles without loss of operational integrity, and are rated to 3,000m water depth due to the excellent insulation and long-term reliability of VICTREX PEEK polymer. With proven performance in hostile environments, the high performance thermoplastic makes the connectors suitable for deepwater and high pressure, high temperature (HPHT) wellhead and downhole applications. Beyond reducing downtime due to its excellent resistance to sour gas and customer-defined critical chemicals, the high-end thermoplastic allows for additional cost savings through the optimisation of tooling and moulding equipment.
“With Victrex having 35 years of experience in developing thermoplastics that can be considered the industry standard for oil and gas components, we knew from the start of the project that we wanted to specify VICTREX PEEK polymer. Today, our connectors, depending on selection, are able to perform in temperatures up to 150°C and in pressure requirements up to 103.5MPa”, stated Gareth Eccles, moulding technologist for OneSubsea. The company´s connectors are resistant to typical oil and gas fluids including seawater, mineral and silicone oil, and hydraulic fluids. They are also suitable for hydrogen sulphide (H2S) sour gas wells.
