Tips: Installation of Fixed Hydrogen Sulfide (H2S) Detector

Fixed hydrogen sulfide (H2S) detector shall be installed in the areas which are easy to release and gather the hydrogen sulfide gas, such as the drilling site, downhole operation site, gathering station, natural gas evolution field, water treatment station and refinery area.

The mounting site of fixed-type H2S detector should be determined by on-site facilities, processes, and the diffusion and gathering of hydrogen sulfide gas.

The fixed hydrogen sulfide (H2S) detector should be installed below the release source, and it shall be within 2m outside and within 1m inside. Moreover, the detector is better to be installed at 0.5-0.6m away from the gas release source. The installation height shall be 0.3-0.6m higher than the ground or floor. If the detector is installed lower, it’s easy to be affected by the rain drops, which may damage the detector.

If possible, please select the gas detectors with concentration display and acousto-optic alarm. The operators can observe the existence of hydrogen sulfide gas on site without returning to the duty room to see the alarm controller. It is finally better to protect them.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
