TWI’s experts have designed and commissioned a high-pressure flow loop that allows a range of tests to be undertaken in an environment that is representative of real-world conditions.
The facility, which has previously been used in exposure testing of polymer lined pipe, allows the circulation of ISO 23936-1:2009 sour fluids containing heptane, cyclohexane, toluene, carbon dioxide, hydrogen sulphide, methane and water at pressures up to 89barg and temperatures up to 130°C. Alteration in the internal bore of the pipes allows for tests to be conducted under realistic conditions related to flow and mass transport.
The flow loop accepts a variety of pipe geometries constructed from different materials and so is ideal for testing rigid or spoolable composite pipes with connectors. It is possible to measure the vapour concentration of these fluid components that permeate through the composite wall using gas chromatography.
TWI Members can use the facility for projects such as conditioning sections of fibre-reinforced composites, sealing assemblies and exposure testing of electronic components.
Members will also be able to take advantage of TWI’s established permeation monitoring of gas and liquid phases facility, along with our rapid gas decompression and fluid sampling facilities in order to add further enhancements to any experiments.
