TR-XTREME^® pipe is designed for areas of seismic activity. TR-XTREME is the first and only domestic earthquake resistant ductile iron pipe that provides expansion/contraction and deflection within a single restrained bell joint connection.

TR-XTREME joints provide 2.9″ of extension capability to accommodate ground settlement and soil liquefaction during earthquakes while providing joint flexibility up to 5° for 6″, 8″, 12″, and 16″ diameters. TR-XTREME is also available in 20″ and 24″ diameters, and 20″ provides up to 4° deflection, and 24″ provides up to 3° deflection respectively.

The TR-XTREME joint is a patented joint that incorporates technology U.S. Pipe has learned from over 40 years of designing restrained joints for the water works industry. The TR-XTREME joint is one of the strongest and most robustly designed restrained joints for water works and seismic market. The TR-XTREME restrained joint utilizes the time proven TYTON^® Gasket for a reliable and tight seal. The features incorporated into the TR-XTREME restrained joint design help insure that when disaster strikes, water will be available in times of emergency. TR-XTREME is available with a variety of coatings and linings, including metallic zinc coating.
