Where the drawings indicate "fab short" or "Cab long", cold spring shall be accomplished to the total of these dimensions. Cold spring shall be accomplished according to the following procedure or according to an alternate procedure proposed by the contractor and approved by the Engineer prior to starting the erection. 1. The dimensions of all shop fabricated sections shall be checked by field measurement and any errors shall be corrected or brought to the attention of the Engineer before erection begins. 2. Erection shall start at anchor or terminal points, such as boiler connections, turbine connections, or pump connections. The first pipe section shall be supported in plumb and level position, and may be tied laterally as necessary, during welding and stress relieving. No permanent horizontal restraining devices shall be installed at this time. 3. Successive shop fabricated sections shall be erected by shifting to match the preceding, section so that the "fab short" or "f.ib long" dimensions accumulate into one "final cold spring gap". The sections shall not be rotated from final direction and shall be maintained plumb and level during welding end stress relieving as stipulated in Step 2 above. The location of the final cold spring gap shall: be subject to approval by the Field Engineer. The amount of the Isap shall be the algebraic sum of the "fab short" and "fab long" dimensions in the vertical, axial, and lateral directions. All stress relieving shall be completed before the final cold spring gap is checked and before any cold pull is started. 4. Matchmarks shall be placed at four points on the ends of each pipe at the gap corresponding to the vertical and horizontal centerlines. 5. All permanent piping suyports and restraints shall be installed according to the hanger details. Spring type vertical supports shall be unpinned and adjusted to allow the pipe to move from the erected position to the cold position without exceeding the spring travel. Solid type vertical supports shall be adjusted to final elevations. 6. The ends of the pipe shall be pulled together, applying torsional force if necessary to align matchmarks. The final position of the joint shall be determined, insofar as possible, by the relative flexibility of the two sections. Spring supports shall be checked during pulling and the rated spring travel shall not be exceeded. (DENTON, TFXAS - 4904 ) (MECHANICAL CONSTRUCTION - D-6) 040171 21F-3 The pipe ends shall be held rigidly in place and the welding and stress relieving shall be completed before removal of any of the pulling equipment, A final check shall be made after 10moval of the pulling equipment to verify that the pipe is in proper cold position, Whuin "11011iaton Joints are shown on the drawings, anchors shall be installed Ae tt+qulrao; to prevent damage from the forces generated by the fluid prtisfiura ur the line. Care must be taken in installing expansion joint Anchors to make certain that full play is allowed at all times from Imum to nitnimum temperatures. Expansion bends shall be provided In all small hot lines if required whether indicated on the drawings or soot, 21F.7 PIPE SUPPORTS. Insofar as possible, pipe supports shall be in- stalleJ so as to e vertical in the hot positions of the piping. This shall be accomplished by offsetting the structural attachment from the pipe attachment when the piping is in the cold position. The support assemblies shall not be used for the attachment of rigging to hoist the Pipe into place. The piping shall be securely held in place by other means until the pipe support is completely assembled and attached to the pipe acid building structures and the spring support set to take care of pipe away. All rigging shall be removed in such a manner as to not impose a sudden load on the pipe support. Spring supports shall not be used during hydrostatic testing of piping systems unless they are pinned or blocked to act as rigid supports. All piping having such supports not pinned or blocked shall be held securely in place by other temporary means throughout the testing. After the piping has been completely installed, insulated, and filled with its normal operating medium, the springs shall be adjusted to the "C" or cold position. If necessary the spring support _ Dusted to the "It" or hot position after the line hasbeen aplaced rind service at its normal maximum operating temperature condition. Welding of pipe supports to structural steel forming a part of the build- ing supporting structure shall only be accomplished by means of the electric metallic arc method, and the quality of welding shall be at least equivalent to that as provided by the specifications of the American Institute of Steel Construction.
