Abstract: Mechanical pipe joints formed between first and second sections of metal pipe or tubing. A pin section on the end of the first pipe section has a cylindrical pin section and a formed pin section that provides the bottom contour of a tapered annular cavity and is coated with sealant. A socket on the end of the second pipe section has a cylindrical socket section and a tapered socket section that forms the remaining contour of the tapered annular cavity. The pin is hydraulically forced into the socket until the end of the formed pin section engages the tapered socket section. The cylindrical socket section of the socket has an inside diameter less than the outside diameter of the cylindrical pin section to form an interference fit that provides the strength of the joint. Sealant is extruded longitudinally and trapped in the tapered annular cavity to prevent leaking.
