From Pipelines to Home Heating: The Digital Transformation of Natural Gas Distribution
From Pipelines to Home Heating: The Digital Transformation of Natural Gas Distribution
The distribution of natural gas through Istanbul's pipelines requires the control of temperature, pressure, draft, consumption, and composition to securely reach 16 million people. The digitalization journey begins at the gas takeover points and extends to the combi boilers of residents. SCADA is integrated into all regional and central metering...

How to select the right Leak Detection Methods to cover Legal and Operational Requirements

How to select the right Leak Detection Methods to cover Legal and Operational Requirements
How to select the right Leak Detection Methods to cover Legal and Operational Requirements
Leak detection systems are a crucial part in pipeline safety. Unfortunately, general knowledge about these systems is still limited. Due to advantages and limitations of single leak detection technologies the selection process can be difficult – especially when regulation and different operating scenarios have to be considered. Single methods might...
