1. Measure/determine the minimum <br />(minor) diameter of the ends to be rounded. <br />2. Place the jack and the shaped blocks <br />in line with the minor diameter as shown in <br />the attached sketch using a sound 4"x4" <br />spacer timber cut square to the required <br />length to take up the space. <br />3. Apply a load carefully with the jack <br />only until the "minimum diameter equals the <br />maximum diameter," or until the gland will <br />easily slip over the end. No more jacking should <br />be attempted or necessary - DO NOT ATTEMPT <br />TO PERMANENTLY ROUND END. <br />4. After the joint is completely assem- <br />bled and the bolts (if involved) are uniformly <br />tightened to the required torque, carefully <br />relax and remove the jack and timbers from <br />the pipe. <br />Note: Field rounding operations should be <br />conducted without backfill on any part of <br />large -diameter pipes and prior to encasing <br />any part of pipe in concrete. If the inside of <br />the pipe cannot be accessed to remove jack- <br />ing materials, pipe ends can alternatively be <br />rounded using external clamping means. <br />AMERICAN Fastite® Joint Lubricant <br />Requirement by Size of Pipe <br />.41 <br />~r <br />JV, <br />64" AMERICAN Fastite Joint pipe being <br />installed in a wastewater application. <br />Table No. 2-5 <br />Pipe Size <br />Approx.
