Pipelines and pipeline parts

LLC «Interenergo» is one of the largest engineering companies in Russia, specialized in packaged supply of the pipeline systems for various facilities, including design and development of working construction documentation for the manufactured products. We have many years’ experience in supply of the pipelines for nuclear and thermal power plants, gas, chemical and petrochemical enterprises.As of today we supplied over 12,500 tons of the pipelines, 85% of which were installed at thermal and nuclear power plants in Russia, Belarus, Ukraine, Bulgaria, India, Iran, Turkmenistan and Kazakhstan. Our products are used at more than 50 large facilities, including eleven nuclear power plants.

The strategic partner in manufacture of the pipelines is LLC «TMM-Energostroy Management», which has its own manufacturing complex for production of the pipelines and their parts with a capacity of up to 4,200 tons per year.

All main process operations are automated and are performed using the advanced European equipment, which ensures high productivity and product quality. The existing equipment, accessories and measurement instruments provide in full the manufacturing process and monitoring of the pipeline parts.We have own design office. Individuality of each project and the non-serial production require special attitude and professionalism of the designers, which makes their work an important integral part of the manufacturing process.

The high, medium and low pressure pipelines are manufactured in compliance with the Russian and Western standards from weldless and welded pipes, sheet steel and steel forgings. Both conventional carbon, low-alloy and stainless steel grades in compliance with Russian National Standards ГОСТ (GOST), Engineering Specification ТУ (TU), Industrial Standard OCT (OST), State Standards of Ukraine ДСТУ (DSTU), EN, DIN, ASTM and ASME standards, and specialized heat-resistant steels P91, P92 and their analogues are used as materials.Manufacturing and welding equipment, processes, operators, and testing laboratory are certified by the third party inspection agency for compliance with the requirements of national and international standards and regulations, including the European Directive PED2014 / 68 / EU and German standards AD2000, technical regulations TP TC 032/2013, standards EN10253-2, EN10253-4, ISO3834-2, SNT-TC-1A and ISO 9712, ISO 17025, ASME BPVC Section IX, standards of the Indian Boiler Code (IBR) as well as Safety Rule ПБ 03-273-99, Construction Regulation РДС 03-495-02, Nuclear Power Industry Codes And Standard ПНАЭ Г-7-003-87, РД 03-615-03, Nuclear Power Industry Codes And Standard ПНАЭ Г-7-010-89 и Ruling Document РД 03-614-03. We have the permits issued by the Federal Service for Ecological, Technological and Atomic Supervision for construction and operation of the nuclear power plant packages

In our work we are committed to the principles of occupational health and safety as well as environmental policy. The quality management system complies with the requirements of ISO9001, ISO14001 and OHSAS 18001 standards.

Our advantages:

  • advanced European equipment with eight-year economic life, which makes it possible to manufacture pipelines for critical parameters (high pressure, temperatures, corrosive environments);
  • unique X-ray chambers for quality control of welded joints;
  • package supply of the pipelines, which allows to reduce the cost of their operation;
  • Russia’s unique experience in manufacture and supply of the pipelines made from heat-resistant steels P-91 (10CrMoVNb9-1) and P-92 (10CrMoVNb9-2);
  • Quality system, production processes and personnel certified in compliance with the national and international standards.
