Efficient. Reliable. No welding
STATS DNV Type Approved mechanical pipe connectors provide a cold-work solution, removing the associated risks of welding. Quick and efficient to install, this permanent solution significantly reduces maintenance duration and provides a cost-effective solution for piping repair, tie-in or capping of redundant pipework.
Once installed the integrity of the Connector can be verified with a simple pressure test. An integrated seal verification port provides access to the annulus void between the seals allowing a leak-test to be carried out.
A double block and bleed valve can be fitted to the seal verification port to provide a means of periodically monitoring the integrity of the connection, as part of a routine maintenance or inspection programme. Mechanical connectors have been fitted to a variety of piping systems with a 100% leak-free service history.
Flanged outlet for connecting plain-end pipe to a pre-flanged termination
Coupling for connecting plain-end pipe to plain-end pipe
End Cap for capping plain-end redundant pipe work
Connectors are suitable for topside, terminal, FPSO or subsea installation and compatible with processed water, air systems and hydrocarbon applications. Available to suit a wide range of pipe materials including carbon steel, SS316, 22Cr duplex and 6Mo (titan study ongoing).
No hot-work required, significantly reducing associated risk and costs
Quick to install resulting in timely completion of maintenance activities
Easily installed and commissioned with only basic pipework preparation
Significantly reduces maintenance costs and duration by eliminating the need for welding, associated equipment and personnel
External grip assembly applies even linear and circumferential load around the host pipe, eliminating localised material deformity and localised stress fractures
External lock and seal assembly eliminates flow restriction or turbulence
Removable and reusable with no damage to existing pipework
