Swagelok tube pressure Rating based on repeated pressure testing of the Swagelok tube fitting with a 4:1 design factor based upon hydraulic fluid leakage. Aug 7, 2018 · Swagelok tube fittings are designed to work properly with the tubing that is suggested in the ordering instructions. Not recommended for use with Swagelok tube fittings in gas service. The fittings are vibration-resistant and offer a leak-tight gas seal for applications up to 20 000 psig (1378 bar). 1. See full list on products. Tubing nominal length is 20 ft. 3 and ASME B31. Swagelok stainless steel tube fittings have been repeatedly tested successfully with tubing with hardness up to 200 HV and 90 HRB. The accompanying tables show working pressure ratings of tubing in a wide range of wall thicknesses. Swagelok ® FK series medium-pressure fittings install up to five times faster than cone and thread fittings, reducing installation time, assembly, and maintenance costs. com The pressure rating of a Swagelok tube fitting depends on the lowest rated component in the system in which it is installed. 8 MPa) for ASTM A269 tubing at –20 to 100°F (–28 to 37°C), as listed in ASME B31. Sometimes the lowest pressure rated component is a pipe thread, a pressure gauge, or a valve. swagelok. 3, Process Piping. The tables show working pressure ratings of tubing in a wide range of tube wall thicknesses and outside diameters. . For higher pressures, see the Swagelok Medium- and High-Pressure Fittings, Tubing, Valves, and Accessories catalog, MS-02-472. Allowable working pressures are calculated from an S value of 20 000 psi (137. Except as noted, allowable pressure ratings are calculated from S values as specified by ASME B31. pivyc bca vvldz fih mywh oefju yiugc ctgybo otifvcs gwdx
