It is necessary to shorten one leg of the 45° contain- <br />ment elbow and the side run of the containment tee. <br />Refer to Table IV for the maximum length that can be removed and <br />for the minimum nipple length of both product piping and contain- <br />ment piping. <br />TABLE IV <br />Containment Remove from Remove from Product' Containment <br />Pipe Size 45° Crossover Ell Side Run -Tee Nipple Size Nipple Size <br />(in.)
