ABSTRACT:
A friction sealed coupling assembly (10) for connecting sections of pipe (P1, P2) having a connecting sleeve (12) and a pair of opposed draw sleeves (14, 16). The connecting sleeve is formed of a hollow cylinder (24) having a uniform inner diameter (D2) and an outer diameter that decreases from a midpoint (M) toward each open end (26, 28) resulting in diverging external tapers (T1, T2). One of the draw sleeves is placed over each taper of the connecting sleeve, each draw sleeve having a uniform outer diameter and an inner diameter that decreases from the first end to the second end creating an inner taper. The inner wall of each draw sleeve is oppositely tapered to the corresponding connecting sleeve end. Each draw sleeve has a bolting flange formed at one end. Ends of the sections of pipe to be connected are first inserted in each end of the connecting sleeve. The opposed draw sleeves are drawn together by tightening connecting bolts (22) so the sleeves move toward each other. The tapered internal walls of the draw sleeves compress the oppositely tapered walls of the connecting sleeve until the connecting sleeve walls compress and adhere to the outside of the pipe sections.
