How- <br />ever, it is preferable to bond only that <br />amount of pipe and fittings that can <br />be cured during the same day. <br />1. Curing pipe joints <br />a. Center the heating collar around <br />the bonding area of the joint to <br />be cured (See Figure 1.6.18). <br />Repeat this step for all joints to <br />be cured. <br />b. Plug the heating collar -into a <br />110/120 volt outlet. <br />c. Heat the joints for the length of <br />time listed in Table 1.6.3. <br />NOTE: These cure times are <br />calculated using heating col- <br />lars from Smith Fiberglass Prod- <br />ucts. These heating collars can <br />reach a maximum temperature <br />of 330°F (166°C).
