In the safety system of industrial infrastructure, cable and pipe penetration seals are like “vascular valves”, and their product performance is directly related to the reliability of industrial power transmission, signal control, and equipment operation and maintenance. Once threatened by extreme environments such as water, fire, insect pests, and electromagnetic interference, the equipment may be shut down at the least, or even cause catastrophic accidents at the worst.

As a national high-tech enterprise in the field of industrial penetration sealing technology in China, TST seal technology provides a new generation of modular sealing system solutions for penetration sealing of key parts and facilities in various fields around the world with its military-grade technical background. Today, let us unveil the mystery of this “invisible guard”!

The core advantage of TST seal sealing system: multi-scenario adaptive engineering protection system

In the field of industrial safety, the sealing system is not a simple “leak plugging” tool, but a key component related to the reliability of the overall system. The excellence of TST seal sealing system lies in its construction of a set of “material-structure-function” trinity adaptive protection system. Through modular architecture and intelligent design, it realizes accurate matching of all scenarios from land to sea, from normal temperature to extreme.

01 Infrastructure protection: building a solid safety line in all scenarios

Medical buildings: The positive pressure environment of the operating room and the airtight requirements of the disinfection area are all achieved by TST seal’s “fireproof + high airtightness” combination, adding another insurance for the safety of doctors and patients;
Data center: What is there to fear for a server running 7×24 hours? Fire, water, rodent infestation, electromagnetic interference – TST seal can handle them all, making the “data heart” beat more steadily;
Railway transportation: high-speed rail is speeding, subways are shuttling, and the signal system cannot have any mistakes! The TST seal sealing system supports the rapid laying of cables of multiple specifications, and there is no need to open new holes for later capacity expansion, which saves money and worry;
Airport: From radar antennas to navigation systems, from underground trenches to terminal power distribution, TST seal uses EMC electromagnetic compatibility design to ensure that the aviation signal chain is foolproof.

02 Power breakthrough: Safety valves for energy arteries

Nuclear power: Safety protection requirements are relatively strict. The TST seal sealing system can simultaneously meet the triple protection of fire protection (3-hour fire resistance limit), waterproof (LOCA accident conditions), and radiation protection (10⁶Gy irradiation dose). The penetration can withstand 1.2MPa instantaneous pressure shock (in compliance with RCC-E standards). Traditional sealing structures require the demolition of concrete walls for equipment upgrades, and the manual operation time is limited in radiation environments. TST seal sealing products solve industry construction problems.
Wind power: Offshore wind turbines face salt spray, strong winds, and lightning all year round. The TST seal sealing system uses a lightweight design to reduce the tower load and withstand the bombardment of extreme weather;
Hydropower: The vibration, water pressure, and electromagnetic environment inside the dam can be called a “devil’s test”. TST seal uses a vibration reduction module + impact resistance design to protect every degree of energy in hydropower generation.

03 Industrial Intelligent Manufacturing: A Bodyguard for Precision Equipment

Rolling Stock: Meets the highest fire protection level HL3 of EN 45545-2, 120 minutes of flame retardant time + low smoke density and toxicity, creating a mobile safety cabin for high-speed rail and subway;
Mechanical Equipment: The cable pipes of cranes and robots are often faced with frequent vibration and oil erosion. The TST seal sealing system uses oil-resistant modified materials + fastening design to extend the life of the equipment by 30%;
Smart Factory: Pre-install the openable sealing module in advance, and there is no need to stop the work and transform the newly added cables in the later stage, truly realizing “layout today, upgrade tomorrow”.

04 Maritime Legend: Security Code for 10,000-ton Ships

Transport ships/cargo ships: The most feared thing when sailing at sea is watertight failure and fire spread. The TST seal sealing system has passed strict certifications such as IMO, allowing ships to remain “indestructible” in stormy waves;
Cruise ships/passenger ships: Lightweight design reduces hull weight, non-welding installation simplifies construction, and even upgrades to “green equipment” such as ballast water treatment systems can be easily adapted;
Navy ships: Anti-explosion shock, anti-electromagnetic pulse, and resistant to seawater corrosion, TST seal creates “three-proof armor” for ships to help improve their survivability in maritime operations.

TST seal has successfully passed the formal approval and factory approval of Russian Classification Society (RS) and China Classification Society (CCS). TST seal MCT products are used in modern floating power generation ships, LNG carriers and other special ships jointly built by China and Russia. “Multi-scenario cable and pipeline sealing”, no secondary transformation is required, which has laid a solid foundation for its entry into the global ship and marine engineering field.

05 Marine Engineering: A safety barrier for deep-sea secrets

Drilling platform: TST seal EMC collaborative shielding solution overcomes the triple extreme working conditions of ultra-high pressure, strong corrosion, and flammable and explosive deep-sea drilling platforms. Through innovatively developed composite shielding structure design and corrosion-resistant alloy materials, the electromagnetic interference attenuation rate is successfully increased to 98.5%, and the protection level reaches IP68 standard. With the intelligent monitoring system, 24-hour environmental safety warning is achieved, which significantly improves the safety level and operation efficiency of deep-sea oil and gas exploitation. (Passed ISO 21457 anti-corrosion certification and ATEX explosion-proof certification)
Offshore booster station: Modular standard parts are quickly installed to solve the fireproof sealing problem of offshore wind power cable penetration, which is “blue energy” Development escort.

06 Energy and Chemical Industry: Safety barrier for dangerous scenes

Petrochemical Industry: Variable diameter modules are suitable for pipelines and cables of different sizes, easily coping with complex working conditions of refineries and oil storage depots, and keeping flammable and explosive areas away from safety hazards;
Mining Industry: The risks of dust, moisture, and gas leakage in mines are resolved one by one by the TST seal sealing system, creating a safer working environment for miners.
