Cone and Thread VS. FK Series Compression Tube Fittings?
By switching from traditional cone and thread fittings to FK series compression tube fittings for their medium-pressure applications, offshore operators have realized both labor and cost savings due to the reduced time required to assemble fittings used to connect tubing with system components. In fact, assemblers have been able to complete fitting installations approximately five times faster, all while virtually eliminating rework needs during hydrotesting and acceptance test steps. Additionally, the performance of FK series compression tube fittings is improving system reliability and reducing overall maintenance needs delivering significant savings and a reduced total cost of ownership. With dozens to hundreds of connections required on assets, the faster installation capabilities of FK series tube fittings yield significant time and cost reductions, as well as accelerated deliveries of completed assets.
