Current Positive Seal Coupling Applications


  • Onshore & shallow offshore liquid or liquid rich phase flow / non –sour service for 2-12” NPS API 5L pipes.
  • High-pressure water injection lines with ID FBE coatings
  • Bare or internally coated oil pipelines
  • Shallow water offshore flow lines
  • CRA lined pipes

The Positive Seal Coupling (mechanical connector) is used extensively in highly corrosive pipeline applications including C02 injection, water injection, brine water disposal wells, plus the produced fluids of oil, saltwater, and natural gas containing H2S and CO2. Jetair International is the Patent owner and supplier of a mechanical pipeline connector called the Positive Seal Coupling (PSC).  This system was developed 31-years ago and has been used to construct over 3000KM of pipelines without welding. The PSC system is widely used by Saudi Aramco, Abu Dhabi National Oil (ADNOC) and Petroleum Development Oman(PDO).
