Weldless Pipe Connection | Mechanical Coupling

STATS’ Couplings provide a mechanical pipe joint for the modification or repair of piping and pipelines throughout the oil, gas and petrochemical industry. These maintenance-free Couplings eliminate the need for time consuming, costly and potentially hazardous hot work activities.

DNV GL Type Approval
The DNV GL Type Approved cold-work solution significantly reduces maintenance costs and duration by eliminating the need for welding equipment, personnel, habitat and specialist skills. These mechanical Couplings provide a permanent and verified mechanical connection and have been fitted to a variety of piping systems with a 100% leak-free service history.

External Grip Assembly
The slipover design and mechanical locking assembly does not require specialist equipment for installation and does not introduce localised stress or yield to the host pipe material to provide leak-tight mechanical integrity.

The Couplings are configured with a dual seal assembly allowing the integrity to be verified via seal verification ports. The verification ports provide an external pressure test facility allowing the seal between the pipe and the Coupling to be tested upon activation, prior to re-commissioning the line. Double block and bleed valves can be fitted to the seal verification ports to allow periodic monitoring of integrity once installed.

STATS range of Couplings conform to the ISO 21329 Standard and are compliant with DNV-OS-F101:2012, Submarine Pipeline Repair and DNV-RP-F113:2007, Pipeline Subsea Repair.
