Reverse Arched Fracture Disc (LF)

Reverse Arched Fracture Disc (LF)

A composite assembly consisting of an arched slotted metal bursting disc, a sealing membrane, and a support bracket. The bursting pressure is controlled by the weakened structure formed by slots and holes on the dome surface of the disc. When the protected system exceeds its pressure limit, the bursting disc fractures along its weakest points to relieve pressure.

GB/T 567TSG 92-2026
Concave Grooved Bursting Disc (LC)

Concave Grooved Bursting Disc (LC)

The bursting disc features a weakened groove on its convex side (typically the concave face) in the form of a "cross," "star," or "ring" pattern. When pressure reaches the burst pressure, the disc ruptures along these grooves to relieve pressure.

GB/T 567TSG 92-2026
Reverse-arched grooved rupture disk (YC)

Reverse-arched grooved rupture disk (YC)

Cross, star, or circumferential grooves are machined on the concave surface of the rupture disk. Upon bursting, the disk buckles and reverses toward the concave side while fracturing along the grooves. The convex side is in contact with the medium, and the concave side faces the relief side.

GB/T 567TSG 92-2026
Reverse-arched slotted bursting disc (YF)

Reverse-arched slotted bursting disc (YF)

Reverse-arched rupture disc: The convex side faces the high-pressure side of the pressure system. It consists of a serrated strength membrane and a sealing membrane. When the strength membrane becomes unstable, the composite disc flips, and the serrations on the strength membrane fracture the sealing membrane to open for pressure relief.

Explosion Relief Panels (Square/Circular Rupture Discs)

Explosion Relief Panels (Square/Circular Rupture Discs)

Designed for installation on the top of energy storage cabinets or in dust explosion venting applications. Features precise and stable burst pressure, starting at 0.01MPa. Other pressures are customizable. Multiple structural dimensions available upon request; fatigue resistance and negative pressure performance must be considered.

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.

Safety Valve

Safety Valve

A safety valve is a special valve that remains normally closed and automatically opens under external force to discharge media when the pressure inside equipment or pipelines exceeds a specified limit, thereby preventing overpressure. As an automatic valve, it is primarily used on boilers, pressure vessels, and pipelines to ensure pressure does not exceed safe limits, providing critical protection for personnel and equipment operations.

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.

GB/T 15605
Explosion Suppression System

Explosion Suppression System

In milliseconds, our suppression system detects early pressure changes from an explosion and releases suppressants before destructive pressures are reached, stopping the explosion. Suppressants work by interrupting the combustion reaction: they absorb heat from the flame front, lowering temperatures below the level required for material ignition. They also form barriers between unburned particles to prevent further heat transfer. Explosion suppression technology detects explosions at their earliest stage, sprays suppressants into the vessel to halt the event, and minimizes associated hazards and damage.
