HDSS Pipe High Pressure Restrained Joint With Added Deflection
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 with between 2° and 5° of 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.
