Autoclave 20UFX4466 Union Coupling
Medium Pressure “Slimline SF” Cone & Thread, Pressures to 20,000 psi
Principle of Operation:
Parker Autoclave Engineers Medium Pressure Cone and Thread connections were created for those applications that require higher flow rate capability. Designed for a maximum of 20,000 psi MAWP using high tensile strength cold worked 316 Stainless Steel material as standard. In addition, we offer even larger ID tubing de-rated to 15,000 psi for maximum flow rate capability. This Medium Pressure series has all the benefits of the High-Pressure version with all metal sealing, sizes ranging from 1/4″ to 1-1/2″ and temperature ranges from -423F to +1200F.
Fittings and tubing found in this section are designed using ASME B31.3 Chapter IX standards to be compatible with our 15SM & 20SM, 20DBNV, 20DV Needle Valves, and all of our various ball valve configurations including Subsea. There is a Parker Instrumentation fitting for just about any application of fluids under extreme pressure and/or temperature condition.
Medium Pressure Fittings and Tubing Features:
- Utilize “SF” style high flow Medium Pressure coned-and-threaded connections (“Slimline”)
- Available sizes are 1/4″, 3/8″, 9/16″, 3/4″, 1″ and 1-1/2″
- 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
- Operating temperatures from -423F to +1200F
- Anti-vibration connection components available
- Special materials available when corrosion, temperature, or NACE/ISO 15156 requirements demand
- All Parker Autoclave Engineers fittings are marked with manufacturers name, part number, material, heat code and maximum pressure for complete traceability
Union vs. Straight Coupling Comparison:
In much the same as with a traditional Pipe Union, the Parker Autoclave Engineers Union Coupling is used to easily disassemble tubing runs when valves or fittings need to be replaced after original installation. The Body and Insert are two different pieces in the same assembly. The body can slide down tubing leaving only the insert and the tubing tips engaged. Then with only minimal tube shift, the insert drops out allowing the tubing to be removed avoiding the need to disassemble multiple tubing sections from closest elbow.
