Complete documentation explaining the placement of combustible and toxic gas detectors.
Based on the "Design Standard for Detection and Alarm of Combustible and Toxic Gases in Petrochemical Industry" GB/T 50493, gas detectors are installed at high-risk leakage points such as pipeline flanges, valves, storage tanks, pump areas, boiler rooms, and hazardous chemical workshops for dangerous media such as combustible methane, LPG, hydrogen sulfide, carbon monoxide, and ammonia in the plant area. These detectors are paired with wall-mounted Gas Alarm Controllers to achieve real-time concentration monitoring, audible and visual early warning, and fan/solenoid valve linkage, thus constructing a comprehensive gas safety protection system.
Scenario 1: Diagram and text for a chemical storage tank area
The top and bottom inlet and outlet valves and liquid and gaseous flanges of the storage tank are high-frequency leakage points; combustible gas detectors are installed at low positions (0.3~0.6m from the ground), and toxic gases are arranged in zones according to the specific gravity of the medium; the bus signal is connected to the central control gas alarm controller, and automatic audible and visual alarms are triggered when the threshold is exceeded, which is linked to the spray and shut-off valves.

Scenario 2: Diagram and text for boiler room/gas turbine room
Methane Detectors are installed around gas pipeline bends, pressure regulating valves, and combustion units; the equipment is installed at a low position below to avoid interference from rising hot gas; it supports AC220V main unit linkage with exhaust fan and gas emergency shut-off valve, and real-time monitoring of indoor gas leaks to eliminate the risk of explosion.

Scenario 3: Illustrated Text for Hazardous Chemical Production Workshop
The detectors cover all sealing points of the reactor, transfer pump, and material pipeline; they are designed to distinguish between flammable and toxic gases, and the installation height of toxic gases (CO/H₂S/NH₃) is adjusted according to the gas density; the detectors are connected to the CA-2100A alarm controller on site and the data is uploaded to the IoT platform for remote viewing.

Scenario 4: Illustrated copywriting for underground pump room/enclosed basement
Poor ventilation in the space makes it easy for gas to accumulate, so detectors are densely arranged along the pipeline. They are installed low to the ground and equipped with 4G network-connected home/industrial detectors. When no one is on duty, they can remotely push leak alarms to prevent people from being poisoned or suffocated.

Scenario 5: Illustrated copywriting for restaurant kitchens/commercial kitchens
Install the JT-CA319N household combustible detector under the stove and at the gas pipe valve; it features anti-oil fume and anti-alcohol false alarm design, and can be linked with the gas shut-off solenoid valve and exhaust equipment to provide immediate audible and visual alerts for methane leaks in the kitchen.

Scene 6: Diagram and text for oil and gas pipeline corridors
Detectors are deployed in sections along the entire pipe gallery, with fixed installations directly below pipe welds, valves, and compensators; the RS485 bus connects to the central control multi-channel gas alarm controller, displaying real-time concentrations for each pipe section in zones, and accurately locating abnormal points.
