The current positive seal coupling - mechanical connector system design, patented in 1998, is the result of extensive mechanical and metallurgical re-engineering, finite element analysis, and laboratory testing.

This Coupling System is a high strength, cost-effective alternative to welding for joining NPS 2” through 12” line pipe. Originally developed for use joining internally coated pipe-it eliminates the need for internal girth weld coating.

Since 1979, PSC’s for high-pressure water-injection have been installed in Saudi Arabia, the United States, Libya, the United Arab Emirates, and Oman.



As the water-cut in oil flow-lines starts to increase - so does corrosion. PSC’s combined with internal-coating are an excellent option to mitigate this problem.



Barge rental rates for a conventional set-up can exceed $250K per day. Since the PSC System utilizes a smaller barge and lay-rates are much faster – cost-savings offshore can be significant.
