Earthquake Resistant

Designed for areas of seismic activity. TR-XTREME®

The solution against extreme earthquakes: ductile iron pipes with TR-XTREME® locking system.

As far as piping installation in areas of high seismic activity is concerned, the biggest problem is the high risk of joint disconnection or pipe breakage because they are so rigid and unable to absorb the energy transmitted by the earthquake. Investigation has been going on for years to determine what sort of piping system might provide a solution that would prevent pipelines from disconnecting and keep the pipelines in service after an earthquake.

U.S. PIPE presents TR-XTREME®: A robust, highly resistant and flexible solution which makes it an ideal and innovative solution to solve the problem of pipeline resistance in the event of earthquakes in urban areas.

U.S. PIPE’s patent, based on a development of the traditional TR FLEX® solution, is designed in such a way that the spigot of the pipe can extend freely within the sleeve by up to 2.9″ (7.5 cm) when an earthquake hits. The piping is able to adapt to the expansion and compression of the soil with a deflection capacity of up to 4º at each one of its joints for diameters of 6” to 12”, and 3º in the case of diameters of up to 16”.

US PIPE is currently waiting for the patent for the TR-XTREME® locking system to be approved. It incorporates 40 years’ experience in the design of restrained joints in the water industry and in the earthquake industry market.
