HomeMy WebLinkAboutMETAL PIPE PEN - 22-00694 - U-Haul Bldg B - New Commercial1.Wall Assembly - The 1 or 2 hr fire-rated gypsum wallboard/stud wall assembly shall be constructed of the materials and in
the manner described in the individual U300, V300, U400, V400 or W400 Series Wall or Partition Design in the UL Fire
Resistance Directory and shall include the following construction features:
A.Studs - Wall framing may consist of either wood studs or steel channel studs. Wood studs to consist of nom 2 by 4 in. (51
by 102 mm) lumber spaced 16 in. (406 mm) OC. Steel studs to be min 3-1/2 in. (89 mm) wide and spaced max 24 in. (610
mm) OC. When steel studs are used and the diam of opening exceeds the width of stud cavity, the opening shall be
framed on all sides using lengths of steel stud installed between the vertical studs and screw-attached to the steel studs at
each end. The framed opening in the wall shall be 4 to 6 in. (102 to 152 mm) wider and 4 to 6 in. (102 to 152 mm) higher
than the diam of the penetrating item such that, when the penetrating item is installed in the opening, a 2 to 3 in. (51 to 76
mm) clearance is present between the penetrating item and the framing on all four sides.
B.Gypsum Board* - 5/8 in. (16 mm) thick, 4 ft (1.22 m) wide with square or tapered edges. The gypsum board type,
thickness, number of layers, fastener type and sheet orientation shall be as specified in the individual U300, V300, U400,
V400 or W400 Series Design in the UL Fire Resistance Directory. Max diam of opening is 38 in. (965 mm) for steel stud
walls. Max diam of opening is 14-1/2 in. (368 mm) for wood stud walls.
The hourly F and FH Ratings of the firestop system are equal to the hourly fire rating of the wall assembly in
which it is installed.
1A. Metallic Sleeve - (Optional, Not Shown) - Cylindrical sleeve fabricated from min 0.016 in. (0.41 mm) to max 0.105 in. (2.7
mm) thick sheet steel. Length of steel sleeve to be equal to the thickness of wall. Longitudinal seam of sleeve welded or
overlapped min 1 in. (25 mm). The ends of the steel sleeve shall be flush or recessed max 1/4 in. (6 mm) from wall surfaces.

2.Through Penetrant - One metallic pipe, conduit or tubing to be installed either concentrically or eccentrically within the
firestop system. Pipe, conduit or tubing may be installed at an angle not greater than 45 degrees from perpendicular. The
annular space between pipe, conduit or tubing and periphery of opening shall be min 0 in. (0 mm, point contact) to max 2 in.
(51 mm). 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 36 in. (914 mm) diam (or smaller) Schedule 10 (or heavier) steel pipe.
B.Iron Pipe - Nom 36 in. (914 mm) diam (or smaller) cast or ductile iron pipe.
C.Conduit - Nom 6 in. (152 mm) diam (or smaller) rigid steel conduit, nom 4 in. (102 mm) diam (or smaller) steel electrical
metallic tubing (EMT) or nom 4 in. (102 mm) diam (or smaller) flexible steel conduit.
D.Copper Tubing - Nom 6 in. (152 mm) diam (or smaller) Type L (or heavier) copper tubing.
E.Copper Pipe - Nom 6 in. (152 mm) diam (or smaller) Regular (or heavier) copper pipe.
F.Stainless Steel Pipe - Nom 36 in. (914 mm) diam (or smaller) Schedule 10 (or heavier) stainless steel pipe.
2A. Through Penetrating Product* - Flexible Metal Piping - As an alternate to Item 2, one nom 2 in. (51 mm) diam (or smaller)
