To make risks manageable and maintain an overview of building-related gas installations, marking gas pipes is necessary and mandatory under Dutch and European regulations.
The pipe markings must comply with established standards in terms of colour and print. In addition to the colour, the flow direction, name, chemical formula and any hazardous properties of the medium are shown on the marking.
The markings must be applied at least:
- Every 10 metres
- At every branch and at every tap point
- Before and after a wall, bulkhead or wall penetration
Combigas has standardised the most common pipe markings based on current standards.
