[Gas pipelines and city gas](https://www.materialinsights.org/energy/e_gas_pipelines/) (energy) and [Steel](https://www.materialinsights.org/commodities/steel/) (commodity): 2 relationships.

## How they are linked

### 1. Material need

*Physical flow · Direct · Steel → Gas pipelines and city gas*

Building or running Gas pipelines and city gas needs steel.

### 2. Price link: pipe material

*Cost and price · Strong · Both ways*

Transmission pipelines use steel line pipe, so steel affects the cost of new lines and therefore network charges. Yearly moves correlate at 0.68, partly because both prices follow general energy and industrial inflation.

- **0.18** monthly change correlation
