The cured in place pipe MN belongs to several trench less and rehabilitation methods which are put into usage when repairing the existing pipelines. It is seamless, lacks joints, and it is tiny tube in between a tube. It contains capacity to rehabilitate many vessels which constitute minute diameter. It is one among the common and wide used technique of rehabilitation in the water application of sewer, pipelines of chemical and gas.
As usual technology keeps advancing, they do not need excavation to rehabilitate pipeline that could leak or remain structurally unsound. According to the design consideration, all excavation should be created although liner is usually installed by man hole. In the case of sewer lines, lateral linkage is restored with no excavation by remote controlled device that drill holes in the liner at the point of the connection.
The other benefit is has smooth surface to the inside and lacks joints. It also has capacity to repair those with many bends. Therefore, special type of consideration of the design is essential in preventing the stretching and also wrinkling. It also decreases level of infiltration leak in pipeline without digging it.
There are several other disadvantages. To begin with, apart from common size, liner is not stocked and it has to be made with specificity for each project. It deserves by pass of motion in the system while other liners gets installed. The protocol of cured in place pipe MN takes five to even thirty hours depending on diameter. Therefore, cautious monitoring is wise for p inspection and testing processes.
Then, obstructions within existing system such as protruding laterals must be removed prior to installation. Therefore, cost should be associated with the similar methods like the spiral wounding and also therm forming. Reason is that, the methods offer same design and solution to same or less costing in given situation.
Therefore, careful monitoring for the release of chemicals agent that are utilized in the process of reaction for the contamination in the downstream part of the rehabilitated ones. Liner materials used for the common sizes are normally felted fabric. It does not rotate around the bends well with no wrinkling as well as going out of the round on the existing corners.
Woven fabric permit them whirl around the bends with limited wrinkling. The more flexible the liners are, the more care needed to be taken during inversion in order to keep it in place on the correct alignment. However, testing installation is constructive in confirming materials put into usage comply with the specified site and also rhyming with the engineering requirements.
To finalize with, cured in place pipe MN samples used must act as representative created by simulating the environment in ground. Wet sandbag is used around the mold where tested samples are obtained from. After retrieving the sample, the size of the specimen are actually scooped from of sample through mechanism of the water cooled equipments. This is important not to produce change in the material property in the preparation process. Specimen is conditioned and tested in universal testing machine for extramural and also the tensile properties in all dimensions.
