Autoclave KCGL40 Anti-Vibration Collet Gland Assembly
High Pressure Cone & Thread, Pressures to 60,000 psi
Principle of Operation:
Parker Autoclave Engineers High Pressure connection is a refinement of the original cone & thread joint. This design has been the standard connection in high pressure technology since its development over 90 years ago. This design set precedence of quality and reliability found in all Parker Autoclave Engineers products to this day.
The pressure handling capabilities of this connection design have been applied successfully to control pressures in excess of 150,000 psi. All-metal sealing allows working temperatures from -423F to +1200F. In addition, many different material options make this connection one of the most versatile ever. Fittings and tubing are designed using ASME B31.3 Chapter IX standards to be compatible with all of our High Pressure Valve and Fitting configurations.
High Pressure Fittings and Tubing Features:
- Utilize “F” style High Pressure coned-and-threaded connections
- Available sizes are 1/4″, 3/8″, 9/16″, and 1″ nominal OD tubing
- Standard fitting material is UNS S31600 with tubing manufactured using UNS S31600/S31603, 316/316L stainless steel material, cold worked to Parker Autoclave proprietary standards; UNS S30400/S30403 304 SS tubing is available
- Operating temperatures from -423F to +1200F
- Anti-vibration connection components available
- High pressure, high cycle Autofrettaged tubing available, along with many material options
- All Parker Autoclave Engineers fittings are marked with manufacturers name, part number, material, heat code and maximum pressure for complete traceability
Series KCGL:
For extreme conditions of vibration and/or shock in tubing systems, such as valves or fittings located on an unsupported line near a compressor, Parker Autoclave Engineers offers coned-and-threaded Anti-Vibration Collet Gland Assemblies. Completely interchangeable with standard Parker Autoclave Engineers high pressure connections, these assemblies provide equally effective pressure handling capability.
In standard connection systems, the bending stresses on the threaded area of the tubing imposed by excessive vibration or movement may cause premature fatigue failure of the tubing at the back of the thread. The Parker Autoclave Engineers anti-vibration collet gland assembly strengthens the entire structure by moving the stress concentration back to the unthreaded part of the tubing and providing a wedge-type gripping action. Extended vibrational fatigue life results from reduced stress concentration and overall stress level maintained well below the endurance limit of the material.
The Collet Gland Assembly utilizes the same coned-and-threaded features of Parker Autoclave Engineers high pressure connections. In Series KCGL, the gland nut is recessed to accommodate a tapered, slotted collet that grips the tubing at a point behind the threaded area of the tubing.The design provides a slight difference in angles between the collet and the corresponding taper of the gland nut. As the nut is tightened, it acts to wedge the tapered end of the collet into a gripping engagement with the tubing and at the same time forces the collar and tubing assembly into line contact with the connection seat.
