One of the activities of the firm 'Eco-RTI-Holding "is the development and manufacture of inflatable sealing, rubber plugs designed to overlap the cavity gas pipelines, water and sewer pipes from 100 to 1400 mm during the emergency and repair work on the pipelines. Rubber plugs are made of durable materials – rubberized fabric, rubber, with high mechanical durability, reliability, resistance to corrosion. Plugs pipelines can operate in temperatures from minus 40 to plus 60 degrees, are lightweight, easy to use when installing and transportation. Stub pipes are flexible, inflatable cylindrical shells, which are introduced into the pipe through the hole process, and filling them with air cover the inner cavity of the pipe. Through the use of seals is achieved reliable sealing of severed cavity.
The design of the plugs Patent RF 2240467, products are certified. Pneumatic plugs available in the following varieties: Inflatable Plugs for gas ZNG; Inflatable Plugs for water and ZNGV ZNGV Y; Plugs Pneumatic BSA; Pneumatic devices vodozapornye SSP Plugs Inflatable ZNG available for gas with a diameter of 100 to 1,400 mm in length from 500 to 1500 mm, working pressure of 10 to 60 kPa (0.10 to 0.6 kg / cm) depending on diameter. Inflatable Plugs for water and ZNGV ZNGV-U (reinforced) Available diameter of 100 to 1,400 mm in length from 500 to 1500 mm, working pressure of 10 to 100 kPa (0.10 to 1.0 kg / cm) depending on diameter. On demand manufacturing of pneumatic plugs for any other size. Heavy-duty construction stubs ZNGV-U is an inflatable double envelope consisting of a sealed chamber made of rubberized fabric and rubber exterior protective surface coating that protects the cover from being damaged by operation in the pipeline, the inner surface of which corroded with sharp edges, protrusions and irregularities.
