Subsea Mechanical Pipe Connectors
STATS range of subsea mechanical Connectors are used for the tie-in or repair of pipelines and risers. The slipover design and mechanical locking assembly provides a flanged connection without the need for hyperbaric welding, available from 2” up to 48”.
The connector features a dual seal design with independent activation of seals and taper locks for efficient installation and seal testing. STATS Connectors have an extensive track record spanning over 15 years, with 100% leak-free service. Designed in accordance with recognised industry standards and guidelines, the Connector components are compatible with a wide range of fluid types and flow conditions. All Connector components are coated to provide protection for use in hostile operating environments.
Connector Configurations
- Flanged outlet for connecting plain-end pipe to a pre-flanged termination, mis-alignment flange interface available
- Coupling for connecting plain-end pipe to plain-end pipe
- End Cap for capping plain-end redundant pipework
Connector Applications
- Subsea pipeline section repairs
