Gas systems
As a generally recognised rule-setter in public gas supply, the DVGW has formulated the technical requirements for access to gas networks.
The safety of gas installations requires special attention. The DVGW rules and regulations ensure that the generally recognised rules of technology are applied in practice and that a high level of safety is ensured.
The pipelines of the gas network must be maintained at regular intervals and, if necessary, rehabilitated. You will find DVGW codes of practice and standards on all these topics in this section.
