Product Name: Natural Gas Online Analysis Cabinet
Field of application: Online analysis and monitoring of natural gas
Application Area: Explosive atmospheres of Zone 1 or Zone 2 Class I hazardous locations, as well as non-hazardous safe areas in petroleum, natural gas, chemical and other industries.
Standards applied: GB/T 25844-2010, GB/T 29812-2013, GB/T 29814-2013, GB/T 3836.1-2021, GB/T 3836.2-2021, GB/T 3836.34-2021, GB/T 28766-2018
It meets the specific environmental requirements of complete online analytical instrumentation systems—such as temperature, humidity, dust protection and explosion protection—thereby providing a safe, stable and reliable operating and running environment for the instruments. This highly integrated analysis cabinet effectively assists natural gas enterprises in monitoring gas conditions during production under complex operating conditions, ensuring compliance with the quality specifications for commercial natural gas. At the same time, it avoids the complications and errors associated with coordination and integration between different disciplines and trades that arise in non-integrated installations, thereby enhancing the system’s reliability.
