TST seal MCT Perforated Sealing System Six-fold protection Strengthen the safety line of petrochemical and natural gas

TST seal MCT perforated sealing system directly addresses the core pain points of traditional perforated sealing in the oil, petrochemical, and liquefied natural gas industries, such as aging and cracking, failure to meet explosion-proof standards, poor corrosion resistance, and electromagnetic interference. It creates an inherently safe protection barrier with all-dimensional hardcore performance, solving sealing safety problems in high-risk working conditions.

Compatible with all materials, withstands extreme petrochemical conditions

The TST seal MCT perforated sealing system is comprehensively adapted to the stringent safety requirements of the petrochemical industry, from material selection to structural design. The system frame is made of 304/316L stainless steel or Q345D corrosion-resistant material, and the sealing module uses EPDM rubber with excellent weather resistance, which can easily cope with the high salt spray and acid and alkali corrosion environment at the seaside. The working temperature range is -40℃ to +80℃, which completely solves the shortcomings of traditional sealing materials such as high temperature drooling and low temperature brittleness, and maintains stable performance under various extreme working conditions.

Maximizing core parameters to build multiple security barriers

In terms of core security parameters, the TST seal MCT system has reached the top level in the industry, achieving multi-dimensional security protection:

✅ Fire resistance: Complies with GB23864 standard; some products have a fire resistance rating of up to 3 hours, effectively preventing the spread of fire across areas.

✅ Explosion-proof performance: Explosion-proof rating reaches Ex e ⅡC Gc, with peak impact overpressure > 40 bar, perfectly matching the compliance requirements of high-risk explosion-proof areas in petrochemical plants.

✅ Sealing and protection: IP68 protection rating, water tightness 0.4MPa, air tightness 0.2MPa, preventing the penetration of flammable/toxic gases and eliminating rainwater backflow.

✅ Electromagnetic protection: Built-in grounding function, shielding effectiveness reaches 42-63dB (14kHz-18GHz), resisting electromagnetic interference and ensuring stable control equipment signals.

✅ Rodent-proof: The fully sealed structure prevents rodents from entering, eliminating the risk of short circuits and leakage caused by cable chewing at the source.

A single system provides six-fold integrated protection: fireproof, explosion-proof, waterproof, corrosion-proof, electromagnetic interference-proof, and rodent-proof, effectively plugging all safety loopholes in the sealing process.

Full-process coverage, adapting to petrochemical safety and compliance requirements.

From sealing the explosion-proof walls of the control room to protecting equipment inlets, from sealing cables passing through walls to sealing oil and gas pipelines through barriers, the TST seal MCT barrier sealing system, with its globally recognized CCCF, explosion-proof, and IP68 certifications, covers the entire petrochemical production process with safety protection, comprehensively eliminating safety hazards in the sealing process, enabling petrochemical enterprises to truly achieve compliant safe production, and building a solid core defense line for inherently safe factories.
