Subsea Mechanical Pipe Connectors
STATS subsea mechanical Connectors are used for the tie-in, repair or end-capping of pipelines and risers. The slipover design and mechanical locking assembly provides a flanged connection without the need for hyperbaric welding.

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.
