Abstract
A repair coupling is herein disclosed which is particularly suited for use with fiber-reinforced thermosetting resin pipe. The coupling comprises a pair of inner and outer sleeves to be secured on respective end portions of a pair of pipe sections to be coupled, a tubular seal carrier, and a clamp. Each inner sleeve is axially slit and has a tapered external thread. Each outer sleeve has a complementary internal thread. The inner sleeves have internal teeth so that threading of the outer sleeves onto the inner sleeves causes the teeth to grip the respective pipe end to secure the inner and outer sleeves thereto. The seal carrier has opposed seal-carrying sections which fit into the respective pipe ends and form internal fluid seals, and a flange between the seal-carrying sections forming a spacer between the adjacent pipe ends. The outer sleeves each have an external groove and the clamp, which comprises a pair of bolt-together semi-cylindrical clamp portions, has internal ribs spaced apart so as to fit in the respective grooves when the adjacent ends of the outer sleeves engage opposite surfaces of the flange. The coupling is readily applied in situ without the need for special equipment.
