Hydraulic testing of pipes. Technology of pipe procession, assembling and welding works.
2. Contents of the project
At the new built and repaired objects of public utilities the pipes made of carbonaceous steel of various standard sizes are used. The pipelines located inside houses, as a rule, have service life 7-10 years, and those located inside of water-mains and located under the ground have service life even less (4-6 years instead of fixed 25-30 years) because of corrosion processes. For repair the significant means are used. As the foreign experience shows, one of perspective directions to improve the corrosion stability of pipelines is the application of pig-iron pipes with spherical graphite, which has corrosion stability 2 - 3 times higher (according to other data the latter is 5-6 times higher) than that of steel pipes.
The project provides organisation of production for processing and preparation for installation of pipes made of spherical graphite pig-iron for needs of Nikolaev public utilities. As a result there should be achieved an increasing of service life of pipelines in 3 times, reduction of operating costs not less, than in 1,5 times, and also energy saving effect during the repair works not less, than 2 times.
