Brief description

This DVGW Code of Practice applies to the planning, manufacture, installation, testing, commissioning and operation of natural gas preheating systems that are installed for process engineering reasons to compensate for the cooling effect that occurs when the natural gas pressure is reduced. These systems are used to preheat gases of the 2nd gas family in accordance with DVGW Code of Practice G 260. If natural gas preheating is required, the natural gas preheating systems required for this are part of the gas pressure regulating system in accordance with DVGW Code of Practice G 491 or the gas expansion system in accordance with DVGW Code of Practice G 487.
