In oil and mining operations, equipment is constantly exposed to harsh environments including high pressure, high humidity, corrosive chemicals, dust, vibration, and extreme temperatures (-40℃ to +125℃ and above). Failure to seal any electrical or instrumentation interface can lead to short circuits, explosions, production shutdowns, or even safety accidents. Therefore, TST SEAL waterproof sealing modules (such as cable entry devices, junction box seals, and through-hole seals) are a critical barrier to ensure the safe operation of the system.

1. 1. Typical Application Scenarios and Challenges of TST SEAL Waterproof Sealing Modules

Application Scenarios | Environmental Challenges

Offshore Platforms/Drilling Vessels | Salt spray corrosion, surge impact, continuous high humidity (IP68+), explosion-proof requirements (ATEX/IECEx Zone 1/2)

Onshore Oilfield Wellhead Equipment | Oil and gas leakage risk, sand and dust intrusion, large diurnal temperature differences, H₂S/CO₂ corrosion

Underground Mine Power Distribution and Control Cabinets | High humidity (nearly 100% RH), methane/coal dust explosion risk, mechanical vibration, frequent movement

Pipeline Valve Assemblies and Instrument Boxes | Exposed to sunlight and rain, contact with chemical cleaning agents, thermal expansion and contraction leading to seal aging

1. 1. Core Performance Requirements of TST SEAL Waterproof Sealing Modules

Protection Level

Minimum IP66 (resistant to strong water jets), recommended IP68/IP69K (can withstand long-term immersion or high-pressure flushing); Mining equipment must comply with GB 3836.1/2 (Chinese explosion-proof) or ATEX/IECEx certification.

Material Resistance

Main Body Material: 316L stainless steel (salt spray resistant), nickel-plated brass (cost-effective), engineering plastics (e.g., PBT+GF, lightweight);

Sealing Ring: Fluororubber (FKM, oil and high temperature resistant), silicone (low temperature resistant), EPDM (moisture resistant);

Prohibited Materials: Ordinary NBR rubber (swells in oil), un-corrosion-resistant carbon steel (prone to rust).

Mechanical Reliability

Vibration Resistance: Passes IEC 60068-2-6 sinusoidal vibration test;

Tensile Strength: Axial tensile force ≥100 N after cable clamping and sealing (prevents cable pull-out);

Pressure Resistance: Some deep-sea applications require withstanding >10 bar hydrostatic pressure.

TST SEAL Waterproof Sealing Module Installation and Maintenance

Supports multi-core cable group sealing (e.g., gland head with separator core); Tool-free quick-installation design reduces downhole operation time; Reusable opening and closing for easy maintenance.

III. TST SEAL Waterproof Sealing Module: Common Types and Selection Recommendations

Type | Applicable Scenarios | Recommended Features

Explosion-proof Cable Gland | Explosive gas environments (Zone 1) | Stainless steel body + FKM sealing ring + ATEX certification

Multi-core Separated Sealing Connector | Multiple signal/power lines for control cabinets | Modular core, supports mixed wiring of 0.2–25 mm² wire diameters

Quick-connect Waterproof Connector | Mobile equipment, temporary power supply | IP68, with locking anti-dislodgement, withstands 5,000 mating cycles

Bulkhead Sealing Plate | Instrument box/junction box wall wiring | Integral vulcanization seal, no single-point failure risk

Intrinsically Safe Sealing Module for Mining | Sensor wiring in coal mines | Complies with GB 3836.4, surface resistance <1 GΩ

1. 1. TST SEAL Waterproof Sealing Module Installation and Maintenance Points

Cable Outer Diameter Matching: The tolerance between the inner diameter of the sealing ring and the outer diameter of the cable should be ≤±0.2 mm;

Torque Control: Tighten to the manufacturer’s specified torque. Overtightening will damage the sealing ring, while undertightening will lead to leakage;

Regular Inspection: Check the sealing ring for aging, cracking, and hardening every 6 months;

Replacement Principle: Once disassembled, it is recommended to replace with a new sealing ring (elasticity is irreversibly diminished).

In the oil and mining industry, the intrusion of a single drop of water can trigger a disaster.

Although small, the waterproof sealing module is the “last line of defense” protecting essential safety. TST SEAL waterproof sealing modules utilize aerospace-grade sealing concepts to build a reliable barrier for every interface—because they deeply understand that in deserts, deep seas, or thousands of meters underground, reliability is the lifeline.
