The annular space between pipe, conduit or tubing and periphery of opening shall be min 0 in. (point contact) and max 2 in. Pipe, conduit or tubing to be rigidly supported on both sides of wall assembly. The following types and sizes of metallic pipes, conduits or tubing may be used:
      A. Steel Pipe — Nom 20 in diam (or smaller) Schedule 10 (or heavier) steel pipe.
      B. Iron Pipe — Nom 20 in diam (or smaller) cast or ductile iron pipe.
      C. Conduit — Nom 2 in. diam (or smaller) steel electrical metallic tubing or steel conduit.
      D. Copper Tubing — Nom 2 in. diam (or smaller) Type L (or heavier) copper tubing.
