Torque Determination, Method of, for Tube or Hose End Fitting Connections, Flared, Flareless or Miscellaneous Screw Thread Style
Torques to be determined for tube or hose end connections shall be specific for a material combination; however, may vary upon consideration of variables for a given tube size. These variables include tube material, fitting material, testing medium, required proof pressure and lubricant used. Resultant torques from substitution of listed variables will vary for a given tube size. Therefore, a developed torque is satisfactory only for the specific combination used in its formulation. These valves are to be used for connecting tubing and hose assemblies to each other and/or to related equipment.
