Cutting and overlapping of pipelines during construction and overhaul.The length of Russia's main pipelines is 227,000 km, including 157,000 km of gas mains.
100% of produced gas, 99% of produced oil, and more than 50% of produced refined products are transported through the system of main transport. In the total volume of transport work (freight turnover), the share of gas is 55.4%, oil - 40.3%, oil products - 4.3%.
Export of gas, oil and oil products is mainly carried out by pipeline transport, including through sea terminals.
Russian pipeline systems developed most actively in the 1960s and 1980s. Currently, 37% of pipelines are operated for more than 20 years, which requires increased attention to their operational reliability and technical safety.
For many years of operation, numerous defects have accumulated, representing a wide range of damages in the form of corrosion, stress corrosion-resistant concentrators, dents, corrugations, through pitting, cracks, etc. All this requires special attention and repair. As the tools of the latter, the service repair services are provided with modern repair technologies. One such is the technology of tie-in and overlap without reducing pressure.
The most important advantage of "hot" tie-ins is that it allows connecting taps or isolating a section of an operating pipeline without stopping its operation.
The specialists of the INTRA Service Company, a member of the INTRATOOL group of companies, can make a cut-in on pipelines with a diameter of 12.5 mm to 1420 mm, while the pipe material can be practically anything (steel, stainless steel, cast iron, polyethylene, asbestos cement, reinforced concrete and etc.). Specialists of the company also have experience in working with a large list of transported products: natural gas, liquefied gas, gas condensate, NGL, ethane, propane, butane, oil, petroleum products, ammonia, nitrogen, water, etc.
The technology of tie-in and overlapping makes it possible to carry out the work without stopping the operation, and hence the loss of productivity is eliminated. The consumer in this case does not experience any inconvenience. Also in the case of non-stop repairs, we get no costs for discharging and collecting oil and do no harm to the environment.
While working with traditional methods of pipeline discharge, we lose the product, experience a reduction in pumping and sales, and create inconveniences for the consumer. Traditional methods lead to additional costs for the discharge of the pipeline and the collection of petroleum products from the barns, as well as causing irreparable environmental losses in the event of environmental pollution
The specialists of the INTRA Service Company have all the necessary approvals and, most importantly, the experience of carrying out the work in almost any conditions. Tapping and overlapping technology is a modern innovative method of carrying out work on various sections of the pipeline without losses, which deserves close attention and implementation at hydrocarbon production, transportation and processing enterprises, as well as in all enterprises with long non-stop production cycles.
