ABSTRACT:
A split sleeve assembly or clamp includes a longitudinally extending body having upper and lower half sections and a cylindrically shaped chamber having two pair of C-shaped flanges that divide the chamber into three sections including two end chambers with two open ends. A pair of glands with one gland disposed at each end of the body abutting the end chambers after being filled with packing materials on each side of a leak. The assembly also includes a pair of split gland elements each of which are held together by a sealing ring for sealing the ends of the assembly. The gland elements also include an integrally formed boss for fitting into an end chamber and compressing the packing material therein. A plurality of swivable bolts disposed at each end of the assembly on the upper and lower half sections are used to tightly seal the ends of the assembly. The assembly also includes a drainage valve centrally located on the lower half section and an injection valve for injecting additional packing material into the upper half section of the assembly.
