Swagelok Tube Fittings

HP air systems have often utilized connections that employ elastomeric ‘o’ ring sealing technology. Due to the effects of compression set of the elastomeric, the HP air system has been susceptible to leakage and system performance has been compromised as a result.

The Swagelok twin ferrule fitting is a mechanical seal, with no soft parts. The immediate benefit is that the systems can be flattened and maintained within operational Fleet Time without risk of leakage. This has resulted in less operational defects, more system and equipment up time – ‘Fit and Forget!’

Swagelok VB03 and VB04 Double Block and Bleed Valves

Traditionally equipment and systems were susceptible to unscheduled down time due to poor performance and reliability of the valves employing elastomeric sealing technology.

Swagelok VB03 and VB04 Double Block and Bleed provide reliable two valve isolation (a safety requirement) allowing maintenance of systems and equipment. This has improved operational up time. Ships operators and maintenance personnel are experiencing improved system efficiency due to tighter zoning and more reliable safety shut off.

Tube Fittings and W60 Series Valves

Piping was used extensively in the vessels. This posed a number of problems. The pipe leaked, required rework and was difficult and time-consuming to install.

Swagelok converted the vessels from pipe to tubing. This helped the US Navy achieve savings over welded pipe and performance improvements over competitive tube fittings.

The tube assembly does not leak, requires less rework and is easier to install. Also, the tubing is 4 X faster to install than the previously used pipe! This means greater efficiency and reduced labour costs.
