SHEFFIELD, UK -- Subsea Riser Products (SRP) has attached flanges for a Venture Production drilling riser using a new shrink-fit process. The flange was heated to over 400° C (752° F) using induction coil, causing it to expand over the end of the 19.25-in. (49-cm) ID riser pipe section. The flange and the pipe were brought together using a purpose-built jig to ensure precise alignment. The assembly cooled to create a high-quality structural connection and a gas-tight seal, the company says.
