The HDSS® pipe is the newest addition to the U.S. Pipe product line. It was designed as a high pressure restrained pipe with added deflection. HDSS Pipe and Fittings can provide a true 350psi working pressure with a flexible restrained push-on joint for 4”- 54” ductile Iron pipe and fittings. The HDSS Restrained Joint has a working pressure rating that is variable depending upon the class of pipe it is used with. HDSS provides up to 5° deflection to allow for alignment and settlement issues in buried applications. The simple robust design and added deflection make this the strongest joint on the market, and ideal for bridge piping, horizontal directional drilling (HDD) and pipe bursting applications.
To facilitate quick, easy and trouble free installation, ductile Iron locking segments are inserted through a single slot in the bell face and slid into position around the bell to provide a positive axial lock between the bell interior surface and a retainer weldment on the spigot end of the pipe. A rubber retainer installed between the locking segments completes the installation and ensures the segments stay in place while the joint is extended to engage the restraint. The HDSS joint can be easily disassembled by reversing the installation procedure with no need of special tools or shims.
