Earthquake Resistant

Anti-seismic ductile iron pipes

The latest in anti-seismic technology. Lok & Play®

Construtec’s extreme earthquake solution is the high-resistance joint Lok&Play® for ductile iron pipes.

The biggest problem with the pipes which are installed in areas of high seismic activity is the high risk of disconnection of the joint, or breakage of the pipes due to their high rigidity and not being able to absorb the energy transmitted by the earthquake. For years, researchers have been carried out on how the piping system should be to provide a solution that ensures that the pipes are not disconnected, keeping them in service once the earthquake has passed.

Construtec provides a robust, highly resistant and flexible solution that makes it an innovative and ideal solution to solve the pipeline resistance problem during an earthquake in urban areas.

Lok & Play® locking patent, based on a development of the traditional restrained joint, is designed so that the spigot of the tube moves freely in extension within the cup in a length of 2.9 ”(about 7.5 cm) during the earthquake.

The pipe is capable of accommodating expansions and compressions of the soil with a deflection capacity of up to 4º in the entire circumference of the pipe and in each of its joints for diameters from 6 to 12 “, and from 3º to 16°.

The Lok & Play® locking joint is under patent approval by the manufacturer and incorporates 40 years of experience in the design of restrained or latched joints for the water industry and earthquake industry market.
