TST Seal MCT Transit Sealing System: A Core Choice for Safety in the Energy Transition

Driven by global “Dual Carbon” goals, sectors such as hydrogen energy, carbon capture, e-fuels, and biofuels are rapidly expanding. Cable and pipe penetrations in critical equipment—including hydrogen compressors, explosion-proof cabinets, and gas pipelines—serve as vital nodes for fire protection, explosion prevention, and gas-tight sealing. Seal failure in these areas can easily trigger safety incidents such as hydrogen explosions, gas leaks, and fires.

Featuring military-grade technology, all-scenario protection, and a modular design, the TST Seal MCT transit sealing system precisely meets the rigorous demands of energy transition projects. It establishes a robust safety barrier at penetration points, making it the preferred sealing solution for new energy projects.

All-Scenario Adaptability: Covering Core New Energy Equipment and Facilities

The system is fully compatible with various structures—such as modular containerized hydrogen refueling stations, carbon capture units, and cast-in-place production facilities—precisely addressing core protection needs:

✅ Hydrogen Compressors / Gas Pipelines: Superior gas-tight performance blocks hydrogen and process gas leaks, prevents explosions caused by oxygen-hydrogen mixing, and meets high-pressure gas transport requirements.

✅ Converters / Partition Walls: A-60 fire-rated sealing combined with IP68 dust and water protection; halts the spread of fire and withstands harsh environments like humidity and salt spray.

✅ PLC/DCS Control Cabinets / Explosion-Proof Cabinets: Specialized Ex-rated explosion-proof modules prevent explosions caused by electrical faults, suppress electromagnetic interference, and ensure the stability of precision control systems.

Six Core Advantages: Directly Addressing Pain Points in the New Energy Sealing Industry

1. 1. Multi-layered Protection: A One-Stop Solution for Safety Risks

Utilizing proprietary low-smoke, halogen-free EPDM material, the system integrates six key functions: fire protection, gas-tight sealing, explosion prevention, electrical safety, impact resistance, and dust/water protection. Certified by authorities such as CCCF, multiple international classification societies, and ISO standards, it replaces traditional multi-product combinations and eliminates compatibility risks.

1. 2. Flexible Adaptability: Single Opening Accommodates Multiple Penetration Specifications

Featuring innovative peelable variable-diameter technology, the system eliminates the need to replace sealing components. A single opening can accommodate dozens of pre-terminated cables or pipes, saving space and simplifying initial design. 3 Built-in expansion capability for full-lifecycle project upgrades

A redundant design reserves spare capacity, eliminating the need for new openings when adding pipelines later; this preserves fire and gas-tight integrity, allows for long-term adaptability with a one-time installation, and reduces O&M and modification costs.

4 Efficient installation, significantly shortening project timelines

A modular, “building-block” design supports single-sided installation without complex welding, enabling rapid deployment in challenging conditions; this saves over 70% of the time required for design, installation, and maintenance compared to traditional solutions.

5 Corrosion and aging resistance for harsh industrial environments

The rubber modules resist hydrogen and chemical corrosion, while metal components utilize 316L stainless steel; with a service life exceeding 10 years, the system is suited for the extreme conditions found in hydrogen energy and carbon capture projects.

6 Professional explosion protection, ensuring safety in hazardous areas

Specialized explosion-proof solutions meet the required safety ratings for hazardous zones, drastically reducing the risk of explosions caused by gas leaks or electrical faults.
