ABSTRACT:
An axially tensioned pipe joint for joining two pipes is disclosed. The pipe joint comprises a first PVC pipe having an outer surface. The pipe joint also comprises a second PVC pipe having a bell end which fits onto the spigot end. The bell end has a plurality of angularly-spaced-apart holes extending radially through the bell end. A set of radial fasteners can be inserted into the holes so as to engage the outer surface of the spigot end to prevent relative axial movement of the first pipe with respect to the second pipe. The radial fasteners have a surface containing a hard material which is harder than the material of the second pipe and roughen the holes during insertion thereby creating a friction fit resisting removal of the radial fasteners. The pipe joint can be used for horizontal direction drilling.
