Positive arch rupture disk
Passive Security ProtectionConcave rupture disc

Positive Arch Blanking Type Bursting Disc

The rupture disc with positive arch and slotted design is suitable for gas-liquid media. Its arched structure distributes pressure evenly, and it fractures along the pre-scored lines upon bursting without generating fragments. Ideal for safety relief in chemical and pharmaceutical industries.

GB/T 567ASME Section VIIIEN 14694
Concave Grooved Bursting Disc
Passive Security ProtectionConcave rupture disc

Positive Arc Grooved Type Rupture Disk

The positive-arch grooved rupture disc uses precision grooving technology, is suitable for medium and low-pressure applications, offers high burst pressure accuracy, and is widely used in petrochemical, pharmaceutical, and other scenarios requiring precise pressure relief.

GB/T 567ASME Section VIIIEN 14694
Reverse Arch Slotted Bursting Disc
Passive Security ProtectionReverse Arch Bursting Disc

Reverse-bulge slotted rupture disc

The reverse-arch slit rupture disc features a reverse-arch design for enhanced pressure resistance, making it ideal for safety relief in high-pressure applications. It is widely used in new energy sectors such as energy storage and hydrogen energy.

GB/T 567ASME Section VIIIAPI 526
Reverse-arched grooved rupture disk
Passive Security ProtectionReverse Arch Bursting Disc

Concave Grooved Bursting Disc

Reverse-arched grooved bursting disc: Combines a reverse-arch structure with precision grooving to achieve accurate bursting under high-pressure conditions, ideal for applications requiring extremely precise safety relief.

GB/T 567ASME Section VIIIEN 14694
Flat diaphragm rupture disc
Passive Security ProtectionFlat rupture disk

Flat-blade rupture disc

The slotted flat rupture disc utilizes precision laser slotting technology, making it ideal for low-pressure, large-diameter applications. With a large burst area and high discharge efficiency, it is the optimal choice for dust explosion environments.

GB/T 567EN 14798NFPA 68
Explosion-proof board
Passive Security ProtectionExplosion-proof board

Explosion-proof panel

The explosion-proof panel is made of high-strength metal and rapidly vents pressure upon an explosion. It is designed for large-diameter equipment and piping systems to effectively protect both equipment and personnel.

GB/T 567EN 14798NFPA 68
Flameless vent
Passive Security ProtectionFlameless Venting Device

Flameless Venting Device

Flameless venting devices extinguish flames while relieving explosion pressure, making them ideal for indoor equipment installation. They effectively prevent flame propagation and protect personnel and equipment safety.

EN 16009VDI 3673NFPA 68
One-way explosion-proof valve
Passive Security ProtectionExplosion-proof valve

One-way explosion-proof valve

The unidirectional explosion-proof valve closes rapidly upon an explosion, preventing flame and pressure waves from propagating along the pipeline. It safeguards upstream equipment and personnel and is designed for unidirectional material transport pipelines.

EN 16447NFPA 652GB/T 15605
Bidirectional explosion-proof valve
Passive Security ProtectionExplosion-proof valve

Bidirectional explosion-proof valve

Bidirectional explosion isolation valves prevent explosions from propagating in both directions, making them ideal for two-way material transport or complex piping networks to provide comprehensive explosion protection.

EN 16447NFPA 652GB/T 15605
Spring-loaded safety valve
Passive Security ProtectionSafety Valve

Spring-loaded safety valve

The spring-loaded safety valve features a precision spring mechanism. It automatically opens to relieve pressure when system pressure exceeds the set point and closes automatically once pressure returns to normal, allowing for repeated use.

GB/T 12243ASME Section VIIIAPI 526
Nitrogen Blanketing and Inerting System
Active Security ProtectionNitrogen Blanketing and Inerting System

Nitrogen Blanketing and Inerting System

Nitrogen blanketing systems inject inert gases like nitrogen into protected spaces to reduce oxygen levels to safe limits, eliminating explosion risks at the source. Ideal for safeguarding sealed vessels and storage tanks.

EN 14710NFPA 69GB/T 3836
Spark detection and extinguishing system
Active Security ProtectionSpark detection and extinguishing system

Spark detection and extinguishing system

The spark detection and extinguishing system uses high-sensitivity infrared sensors to monitor sparks inside the pipeline in real time. It activates the extinguishing mechanism within milliseconds, eliminating explosion risks at the earliest stage.

NFPA 652EN 15904GB/T 15605
Explosion Suppression System
Active Security ProtectionExplosion Suppression System

Explosion Suppression System

Explosion suppression systems instantly release suppressant upon detecting an initial explosion signal, quenching the event at its onset. Designed for comprehensive protection of enclosed equipment and piping systems.

EN 14373NFPA 69GB/T 15605
