Witrynahigher ambient temperatures, longer impulse lines are required. For lower ambient temperatures, shorter impulse lines are required. Also, most users add a little more pipe length for added peace of mind. If the impulse lines are too long, other problems may present themselves: • Damping of the pressure signal • Blockage of the pressure signal WitrynaCapillary tubes. Capillary tubes with a maximum bore of 0.0158 in., available in a wide range of stainless steels. Alleima capillary tubes are characterized by tight tolerances, and the inside surface of the tubes is free from oil, grease and other particles.
