U.S. Pipe Telescoping Sleeves are Ductile Iron restrained joint fittings which can be utilized to provide expansion and contraction capability in a pipeline. Telescoping sleeves are available with TR FLEX ends for 4″ through 24″ sizes and with HP LOK ends for 30″ through 64″ sizes. The restrained joints of the telescoping sleeves are suitable for 350psi operating pressure in all sizes. Standard lining and coating is an asphaltic material.

The Telescoping Sleeves are capable of extending or contracting from approximately 10″ to 24″, depending upon the nominal diameter.

A special section of Ductile Iron pipe is used in each end of the telescoping sleeve to make up a telescoping sleeve unit. Each pipe spigot end socketing in the sleeve has a weld bead located at a greater distance away from the end of the pipe than the conventional weld bead of TR FLEX / HP LOK pipe. The ends of  the telescoping sleeve unit are provided with either TR FLEX / HP LOK socket(s) or with TR FLEX / HP LOK plain end(s) with weld beads as required.
