Repurposing of Natural Gas (NG) pipelines with MOP not exceeding 7 bar for NG/ Hydrogen blends

active, Most Current
Organization: IGEM
Publication Date: 1 December 2022
Status: active
Page Count: 26
scope:

This Supplement covers the design, construction, inspection, testing, operation and maintenance of steel and polyethylene (PE) pipelines and the repurposing of NG pipelines for NG/H blends with MOP not exceeding 7 bar for:

• NG/H blends with less than or equal to 20 mol.% Hydrogen.

The Supplement outlines the requirements for repurposing an existing NG distribution pipeline for NG/H blends operating at pressures below 7 bar which has been maintained in accordance with previous versions of IGEM/TD/3, including pipelines constructed of iron and fabricated by different methods historically. It also covers modification and connection to these existing pipeline systems.

This Supplement covers PE and steel pipelines operating at a MOP not exceeding 7 bar and at a temperature from 0ºC to 20ºC inclusive for PE and -25ºC to 40ºC inclusive for steel.
