Insert material shall be at least as long as the protective shield <br /> 5. Thermal Hanger Shields: Install where indicated,with insulation of same thickness as piping. <br /> J. Locate hangers at maximum 10'-0"on center at 8"dia.and larger pipes supported from steel joints. Locate hangers <br /> at joist panel points. <br /> 3.03 INSTALLATION OF ANCHORS <br /> A. Install anchors at proper locations to prevent stresses from exceeding those permitted by ASME B31.9 and to <br /> prevent transfer of loading and stresses to connected equipment. , <br /> B. Fabricate and install anchors by welding steel shapes, pleates, and bars to piping and to structure. Comply with <br /> ASME B31.9 and with AWS Standards D 1.1. <br /> C. Where expansion compensators are indicated, install anchors in accordance with expansion unit manufacturer's ' <br /> written instructions to control movement to compensators. <br /> D. Anchor Spacings: Where not otherwise indicated, install anchors at ends of principal pipe runs, at intermediate <br /> points in pipe runs between expansion loops and bends. Make provisions for preset of anchors as required to <br /> accommodate both expansion and contraction of piping. <br /> 3.04 INSTALLATION OF PIPE ALIGNMENT GUIDES <br /> A. Install pipe alignment guides on piping that adjoins expansion joints and elsewhere as indicated. ' <br /> B. Anchor to building substrate. <br /> 3.05 EQUIPMENT SUPPORTS ' <br /> A. Fabricate structural steel stands to suspend equipment from structure above or support equipment above floor. <br /> B. Grouting: Place grout under supports for PiP•mg and equipment ' <br /> 3.06 METAL FABRICATION ' <br /> A. Cut, drill, and fit miscellaneous metal fabrications for pipe anchors and equipment supports. Install and align <br /> fabricated anchors in indicated locations. <br /> B. Fit exposed connections together to form hairline joints. Field weld connections that cannot be shop welded ' <br /> because of shipping size limitations. <br /> C. Field Welding: Comply with AWS D1.1 for procedures of manual shielded metal-arc welding, appearance and <br /> quality of welds made,methods used in correcting welding work,and the following: <br /> 1. Use materials and methods that minimize distortion and develop strength and corrosion resistance of base <br /> metals. <br /> 2. Obtain fusion without undercut or overlap. <br /> 151404 No.[COMM] ' <br />
