§ 2-55. Piping.

Latest version.

A.
Standard full weight wrought iron, steel or brass pipe or copper tubing with substantial fittings shall be used, and shall be carefully protected against mechanical injury. In all piping systems, proper allowance shall be made for expansion and contraction, jarring and vibration. Flexible metallic tubing may be used to reduce the effect of jarring and vibration.

B.
All threaded joints shall be tight and shall be made up with litharge and glycerin or equivalent pipe joint compound.

C.
All piping shall be secured rigidly and protected from injury in a manner which is consistent with good practice.
