MORGRIP® clad and lined pipe connectors enable the only DNV-GL Type Approved means to repair damaged pipelines that are clad or lined with a corrosion resistant alloy.

Following the completion in 2019 of a joint industry project with Chevron and Woodside, we have developed through analysis and testing a reliable, repeatable and predictable method of successfully end sealing onto the inner lining of a clad or lined CRA pipe by mechanical means. The technology is encapsulated in an end seal module which can be engineered into our existing topside, subsea and remote connector technology.

Technical Details:

MORGRIP® clad and lined pipe connectors are designed in full compliance with the pressure / capacity requirements of DNV GL-RP-F113 and ST-F101 where applicable.

For design purposes alternative codes, such as API-5L and  ASME B31.3, can also be used to determine the required test pressure.

All pressure retaining components can be designed in compliance with ASME BPVC VIII Div. 2 on request.
