Robust and Dependable
TUBE TURNS® UHP closures are the heavy-duty version of the TUBE TURNS® legacy line of clamp style (double bolt) closures that span more than 50 years of successful applications in a broad range of sizes and pressures.
This Ultra High Pressure design utilizes a self-energized, metal-to-metal seal that allows pressure containment up to working pressures of 15,000 psi (1,034 bar).
The clamping forces required to obtain this range of pressures is achieved by the use of two forged and machined heavy-duty clamps that are driven by dual heavy-duty, dual actuating drive screws. This combination ensures positive mating of the head and hub sections by encapsulating them in nearly 360° of clamping contact when the clamps are in the closed position.
Low Maintenance
TUBE TURNS® UHP closures include safety features to contain process fluid, protect operators and safeguard the environment. They feature a hinged cover with a pressure warning device and secondary mechanical interlock to prevent accidental opening under pressure.
The fully redundant locking mechanism complies with ASME UG-35 (b). TUBE TURNS® UHP closures are faster and easier to operate than bolted connections.
The low-maintenance design is also easier to service, with all wear parts readily accessible. All components except the main seal ring remain attached to the closure assembly, preventing loss or damage of loose parts.
