PLUMBING PIPING SYSTEMS <br />Section 15400 <br />15-1207 <br />3.07 INSTALLATION OF HANGERS AND SUPPORTS: <br />A. Fasten all piping securely to structure with hangers, supports, guides, anchors, or sway <br />braces to maintain pipe alignment, to prevent any sagging, and to prevent noise or <br />excessive strain on the piping due to uncontrolled movement under operating conditions. <br />Relocate hangers as necessary to correct unsatisfactory conditions that may become <br />evident when system is put into operation. <br />B. Follow drawing requirements and details where special pipe support requirements are <br />detailed on the Drawings. <br />C. Do not support piping by perforated tape, wire, rope, wood, nails, or other makeshift <br />devices. <br />D. Design hangers and supports to support the weight of the pipe, weight of fluid, and <br />weight of the pipe insulation with a minimum factor of safety of five based on the ultimate <br />tensile strength of the material used. <br />E. Burning or welding on any structural member under load shall not be attempted. Field <br />welding not called for on the Drawings or reviewed shop Drawings may only be done <br />with consent and advice of the Architect and after proper provisions have been made to <br />relieve the stress on the member. The boring of holes in beam flanges or narrow <br />members will not be allowed. <br />F. Install hanger on insulated piping in a manner which will not produce damage to <br />insulation. Provide steel pipe saddles as required to protect pipe covering. Install pipe <br />hangers on piping covered with insulation on the outside of the insulation and not in <br />contact with the pipe. <br />G. Fasten hanger rods to concrete structural members with concrete inserts set flush with <br />surface. Install a reinforcing rod through the opening provided in the concrete inserts. <br />Fasten hanger rods to structural members with suitable beam clamps, and provide beam <br />clips to lock clamp securely to beam. <br />H. Use of powder -actuated fasteners will not be permitted for the support of any overhead <br />piping. <br />Turnbuckles, if used, shall have a load -carrying capacity at least equal to that of the pipe <br />hanger with which they are being used. <br />All threaded parts of pipe hanger assemblies shall have full length of thread in service <br />while in use. <br />K. Hanger material shall be reviewed by the Architect before installation. <br />L. Pipe Hanger or Support Spacing: <br />1. Provide pipe hangers or supports at 6 -foot maximum spacing on steel pipe <br />3/4 -inch diameter and smaller and for copper pipe 1-1/2 inches and smaller. <br />2. Support steel piping 1" and larger and copper larger than 1-1/2 inches at 10 -foot <br />maximum spacing. <br />3. Support steel piping used for gas at the following lengths: <br />13 <br />
