The wear point of greatest concern in a pneumatic line is

  • A.the bends
  • B.the straight horizontal runs
  • C.the receiving filter
  • D.the blower inlet

Answer: A

Particles are thrown against the outer wall wherever the flow changes direction, so bends erode long before straight pipe does. Long radius bends and replaceable wear backs are the standard answers. Velocity is the other lever, since wear rises steeply with it.
