Description of distribution plants

General Description

A gas distribution plant is generally made up of:

  • one or more interconnections with the national or regional network of transmission pipelines used to supply the distribution network. At these points (M&R stations) the delivery, filtering, preheating before pressure reduction, pressure regulation, measurement and odorization of gas take place;
  • the gas distribution network operates at different pressures (generally less than or equal to 5 bar), on which intermediate pressure reduction stations and final reduction stations are installed;
  • distribution lines for the delivery of gas to end users, where the gas is measured using suitable measurement groups.

The reference standards for construction and operation are:

  • Ministerial Decree 16/04/2008 "Technical rules for the design, construction, testing, operation and monitoring of works and distribution plants and direct lines of natural gas with a density not exceeding 0.8";
  • UNI-CIG 9167 and UNI-CIG 9571 design/construction and operation/maintenance of Metering & Regulation Stations;
  • UNI-CIG 8827-10390-10619 and UNI-CIG 10702 design/construction and operation/maintenance of Pressure Reduction Stations;
  • UNI-CIG 9165 design/construction/testing of Gas Distribution Networks;
  • UNI-CIG 9860 design/construction/testing of Distribution Lines;
  • UNI-CIG 9036 installation requirements for Metering Units.
