GOST 34741-2021 «Gas distribution systems. Requirements for operation of natural gas distribution networks» and GOST 34670-2020 «Gas distribution systems. Gas pressure regulating stations. Basic provisions» became the most highly demanded standards in April 2022 according to the information received from the Department of Distribution of the Documents on Standardization of the Russian Standardization Institute (FSBI «RST»).
The first document will come into force since June 2022 while the second one has become effective since June 2021. Both documents have been implemented in the Russian Federation for the first time.
GOST 34741-2021 «Gas distribution systems. Requirements for operation of natural gas distribution networks» can be applied to the operation of distribution networks transporting natural gas with the pressure up to 1,2, MPa inclusively. Current document is also applicable to the content and execution of operating documentation during the process of exploitation of natural gas distribution networks.
Standard addresses distribution gas pipelines; technological devices; anti-corrosive protection of steel underground gas pipelines; technical devices and constructions installed on gas pipelines. This document sets the notions of the pipeline and gas distribution system along with 33 another terms. Current document describes the procedure of organization of an operation of gas distribution networks, special training of the staff, procedures of execution of gas hazardous activities and an operation of the automated systems of management of technological processes.
GOST 34670-2020 «Gas distribution systems. Gas pressure regulating stations. Basic provisions» has been developed for the use during the design, construction (reconstruction) and operation of gas pressure regulating stations that are used in gas distribution networks and gas consumption networks. Procedure of conformity assessment can be conducted by the help of this document.
Current standard provides the following term of a gas pressure regulating station. It is a technological device of gas distribution network dedicated for the reduction of the gas pressure and maintaining the gas pressure within the stated limits independently of the gas flow rate.
This standard has been adopted to ensure conditions for safe operation of gas pressure regulating stations; protection of the lives and health of the citizens, property of individuals and legal entities, state and municipal property; environmental protection including the lives and health of animals and plants; energy efficiency; standardization of basic provisions for the design, construction (reconstruction) and operation of gas pressure regulating stations of gas distribution networks and gas consumption networks.
