The pipeline repair using smart sleeve
The pipeline repair using a smart sleeve.
The pipeline repair using smart sleeve is a reconstruction of piping systems trenchless method. It provides a lifetime extension of the old pipe in 50 years, cost savings up to 10 times, high speed of installation and maintenance (3 days), high mechanical strength, durability, resistance to aggressive environments, heat resistance (operating temperature range (From -60 to +135) , resistance to high pressure of the repaired pipe, and the absence in these sediments.
The pipeline repair using smart sleeve is a reconstruction of piping systems trenchless method. This decision is very important in the modern world, because the pipelines in Russia are in a derelict state and in urgent need of repair:
– in the housing sector — more than 65%
– oil and gas pipelines — more than 45%.
The principle of the technology consists in the following. In the pre-treated worn-out pipe placed smart sleeve – the plastic tube of smaller diameter. With the help of steam-generating installations the design is heated to a plasticizing temperature (about 150). Due to relaxation properties of molecular bonds deformirovannykh intelligent sleeve under the influence of temperature expands against the wall of the recovered tubing and creates a new wear-resistant interior coating of the pipeline.
Smart sleeve more durable and abrasion resistant than regular plastic. He will not lose qualities, even when processing aggressive chemicals. The irradiation increases the temperature of the polymer up to 135 degrees, which allows its use in hot water systems.
Smart sleeve is designed:
– for pipeline rehabilitation coating internal surfaces of pipes with a layer of temperature – and chemical-resistant, high-strength difficult-modified polymer,
– for lining of pipes technological purposes difficult – modified polymer.
– resource conservation (extension of service life of the old pipe in 50 years)
– low cost of using the technology (in comparison with replacement or overhaul), saving up to 10 times for up to 50 years
– high speed of installation and maintenance (3 days)
– high mechanical strength and durability,
– high resistance to aggressive media,
– temperature resistance, large temperature range (From -60 to +135),
– resistance to high pressure,
– absence of deposits (material of pipes contributes to the formation on its surface of solid residues),
– absence of toxic and physiologically harmful substances and properties.
– the enterprises engaged in the supply (allocation) water (hot and cold) and gas to consumers in settlements
– enterprises that have to operate the network of pipelines for various purposes, including for use in aggressive environments (oil, oil products, chemical products,etc.)
– for enterprises engaged in the repair of pipelines for various purposes,
– enterprises engaged in oil and gas production and transfer of oil products.
