Mechanical Connector

Efficient. Reliable. No welding.

STATS 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.

Connector Configurations

  • 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.

OPERATOR BENEFIT

  • 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
