Slope impulse piping toward instrument for liquid and steam service. b. Slope impulse piping away from instrument for gas service. 3. Impulse piping shall be continuously supported with 12-gage aluminum angle and held in place with appropriate tubing clips and fasteners. Install tubing supports in such a manner to preclude fatigue failure of tubing due to vibration. B. Inslall expansion loops in impulse piping installations where movement of last block valve and instrument is not irt same plane or length of expansion varies. C. Suppod pressure gages and other instruments connected to impulse piping independently_of tubing. Provide ample expansion loops in tubing connections to instruments subject to vibrations to prevent failure due to metal fatigue. D.
