CoInafsletcatilo nA Prouinbta E nEgningeeirninege Prriancgtic Pesractices Pipe Erection and Testing 5.9.2 (*)Engineered pipe support drawings shall be made for all piping NPS 3 and larger, see EP 5–1–3. The engineered pipe supports shall be shop fabricated and shipped assembled to the maximum extent possible. All engineered pipe supports are subject to the approval of the Owner’s Engineer. In addition to the engineered pipe supports specified on detailed design drawings, field engineered pipe supports for piping NPS 2 and smaller shall also be installed to prevent undesirable vibration, sag, lateral movement, or stresses. 5.9.3 (*)In order to standardize the appearance and design of field–engineered pipe supports, the contractor shall prepare a set of standard support drawings which illustrate all types of hangers, brackets, and supports as generally required for small diameter piping, NPS 2 and smaller. These designs shall be subject to the approval of the Owner’s Engineer. The piping support contractor will, upon noting the size, location physical characteristics, and available supporting structures choose the type of support best suited for the applicable application. 5.9.4 (*)Anchors and guides shall not be added in the field without prior consultation with a qualified piping stress engineer, and the Owner’s Engineer. 5.9.5 Fabricated engineered pipe supports shall be installed at the locations indicated on the piping isometric drawings and in accordance with the erection information provided on the Pipe Support design drawings. 5.9.6 Any pipe support designed to take pressure thrust loads of expansion joints (ex. Kick Plates) shall be labeled with a stainless steel nameplate. The letters, numbers and figures shall be at least 5/32 inch high. A drawing of the nameplate shall be included in the Manufacturer’s pipe support drawings. Each nameplate shall be stamped with at least the following information: 1) Expansion joint ID number 2) Pipe support ID number 3) Maximum design pressure (psig) 4) Maximum pressure thrust capability (lbf) 5.9.7 The clearance between a kick plate and a pipe shall be inspected and verified correct per the kick plate design drawings prior to hydrotesting and/or startup of the line. 5.9.8 The piping support contractor is to provide temporary supports for hydrotest where designated and/or as required. These temporary supports shall be removed immediately after successful completion of the hydrotests and after the piping is drained. 5.9.9 The piping support Contractor shall make the adjustment to the length of the rods, support brackets and trunnion supports as necessary. 5.9.10 Base springs which rest on concrete at grade, or platform decks shall be cinch anchored or tack welded, unless anchor bolts are provided. 5.9.11 Shims under base elbows shall be stitch welded to the base of the trunnion support after all joints in piping are made up. Shims under other pipe or sliding supports shall be stitch welded to support crossarms after all joints in the piping are made up. 5.9.12 Final adjustments to supports on piping connected to tankage shall be made after hydrotesting of the tank and bolting of tank flange joints. 5.9.13 When pipe supports incorporate springs which are preset by the Manufacturer to a specified cold load setting, spring stops such as set screws, etc., shall be removed after the field hydrotest and prior to start–up, unless specified otherwise on the pipe support detail sheets.
