Gaugeable Tube Fittings and Adapter Fittings 7
Thermal Shock
The elastic, live-loaded two-ferrule design compensates for changes in temperature during system start-up and shutdown and helps eliminate leakage related to rapid thermal expansion or contraction.
Swagelok has conducted tests that demonstrated the capability of Swagelok tube fittings to withstand thermal shock and high temperature.
Contact your authorized Swagelok representative for more information about thermal shock test reports.
Compliance with Industry Standards
Swagelok Company works with standards organizations around the world to provide you with products that address your needs.
See Materials, page 8; Thread Specifications, page 8; and Pressure Ratings, page 9ection 09, for more information about the specifications to which Swagelok tube fittings are manufactured.
Contact your authorized Swagelok representative for more information about Swagelok tube fitting certifications.
Installation
The Swagelok tube fitting installation advantages: ■ Easy to install
■ No torque is transmitted to tubing during installation
■ Swagelok gap inspection gauge assures sufficient pull-up upon initial installation.
Swagelok tube fitting components provide exceptional dimensional, metallurgical, and mechanical uniformity that allow predictable, repeatable installation.
Swagelok authorized sales and service centers offer installation training seminars that provide additional information on:
■ The requirements for making safe, leak-tight connections
■ A variety of tools and accessories designed for use with Swagelok tube fittings.
Corrosion
Swagelok tube fittings are available in a variety of materials, including controlled-chemistry 316 stainless steel and many other alloys for enhanced corrosion resistance in a variety of applications, including sour gas and subsea systems.
Swagelok has conducted tests in accordance with ASTM B117-95 to evaluate the corrosion resistance of Swagelok tube fittings.
Contact your authorized Swagelok representative for more information about corrosion resistance test reports.
Intermix/Interchange
This practice can be dangerous. Leak-tight seals that will withstand high pressure, vibration, vacuum, and temperature changes depend on close tolerances and consistent, exacting quality control in conjunction with good design principles. The critical interaction of precision parts is essential for reliability and safety.
Components of other manufacturers may look like Swagelok tube fitting components—but they cannot be manufactured in accordance with Swagelok engineering standards, nor do they benefit from innovations in design and manufacture defined by 36 active Swagelok tube fitting patents issued since 1989.
