Flat Spacing Bursting Disc (PF)

Flat Perforated Bursting Disc (PF)

The slotted rupture disk consists of a slotted membrane paired with a sealing diaphragm, with the bursting pressure controlled by weakened structures between the slots. During pressure relief, it opens by tearing along the slots. Suitable for low-pressure applications such as pipelines and vessels, this rupture disk offers excellent sealing performance and a large discharge area. Application areas include: petrochemicals, coal chemical processing, pharmaceuticals, fertilizers, plastics, grain, pigments, pesticides, and tobacco industries.

Flameless vent

Flameless Venting Device

Dust Explosion Safety Protection – Flameless Venting Device. Static Opening Pressure: 0.01MPa@22℃. Shell Material: Carbon Steel / 304 Stainless Steel. We offer a variety of flameless venting devices in multiple forms and sizes to meet diverse operating conditions. Burst disk types include flat slotted and dome slotted configurations. Compliant with EN 16009. Indoor flameless venting units consist of a vent panel and a stainless steel flame arrestor layer. During an explosion, the vent panel opens to release pressure; the flame and pressure pass through the stainless steel flame arrestor, where the flame is rapidly cooled. Dust remains trapped within the device, preventing dust cloud formation and secondary explosions.

Explosion-proof Valve (Uni-directional / Bi-directional)

Explosion-proof Valve (Uni-directional / Bi-directional)

Passive flame arrestors rely on mechanical isolation, including single-way, double-way, and dual-flap valves. They support horizontal and vertical installations. Flame arrestors work with suppression or venting systems to prevent deflagration from spreading between connected process equipment. All these products use mechanical barriers to isolate explosion incidents.

Spark detection and extinguishing system

Spark detection and extinguishing system

Spark Detection and Extinguishing System: Millisecond-level response (from detection to actuation) to identify and eliminate ignition sources before an explosion or fire occurs. Divided into Prevention Systems (extinguish sparks at the source) and Protection/Suppression Systems. Applicable across chemical, pharmaceutical, grain processing, wood processing, new energy, papermaking, metal grinding, steel, coal chemical, and recycling industries. Protection systems include rapid suppression and rapid water mist systems. Key components: spark detection probes, anti-interference hub boxes, control cabinets, alarm lights, pressurized water/suppression-extinguishing systems, solenoid valves, and spray extinguishing devices.
