Victrex, a global leader in high-performance PEEK and PAEK polymer solutions, announced that its Victrex CT polymers have met the stringent specifications outlined by Shell for ball valves in cryogenic services.
The latest Material and Equipment Standards and Code (MESC) SPE 77/302 (Valves-General Requirements) and SPE 77/200 (Valves in Low Temperature and Cryogenic Services) by Shell, the global group of energy and petrochemical companies, now include ‘CRYO-PEEK’ as a designated material for cryogenic ball valve applications. Victrex CT polymers have successfully met these specifications, placing them as a viable alternative to PCTFE for cryogenic ball valve applications.
The updated MESC SPE 77/302 and SPE 77/200 recognize PEEK as soft seat/insert material for ball valves used in cryogenic conditions as ‘CRYO-PEEK’. This approval expands opportunities for valve manufacturers, offering high-performance PEEK polymers as a reliable solution in cryogenic environments.
Key advantages of Victrex CT polymers include an extended temperature range from -269°C to higher than +260°C, improved mechanical and thermal properties compared to fluoropolymers such as PCTFE, and confidence of supply from Victrex, which has a regional warehouse network.
The Material and Equipment Standards and Code (MESC) set by Shell is pivotal within the oil and gas industry, serving as a benchmark for the design, construction, operation, and maintenance of processing units and facilities. Widely accepted by buyers, these standards represent a key test protocol and a prerequisite for industry acceptance.
