ABSTRACT:
A pipeline is fabricated by forcing the end portions of joints of pipe telescopingly into a coupling member and into fluid tight relationship respective to one another. The coupling member is in the form of a sleeve having opposed cavities which receive adjacent marginal ends of the pipe joints therewith. Each marginal end of the pipe joint is forced into the cavity of the sleeve with great force such that the sleeve cavity holds the pipe ends together with a strong friction fit. Each cavity of a sleeve has a first maginal length with blades formed about the circumference thereof, and another marginal length with a resilient sealing member formed about the circumference thereof, so that both the blades and the seal member are deformed as one of the marginal pipe ends is forced thereinto, whereby the metal bladed part of the sleeve engages and rigidly holds the pipe respective to the sleeve, while the seal part of the sleeve prevents leakage of fluids therethrough.
