End face fully sealed rubber flexible joint

Description :

1. Fully sealed with zero leakage

• Flange and rubber end face100% adhesive fitNo exposed bolts or reliance on gaskets, completely solving the leakage hazards caused by aging of traditional joint gaskets and bolt corrosion.
• The sealing surface can withstand a deviation of 0.5 ° angle and maintain reliable sealing under dynamic working conditions.

2. High strength, pressure resistance, and anti pull off

• built-inGalvanized steel wire/aramid fiber reinforcement layerThe pressure rating can reach up to 16 bar, effectively resisting high-pressure impacts and preventing the ball from detaching.
• The overall vulcanization process seamlessly combines rubber and flanges, increasing tensile strength by 40%, making it suitable for pipeline systems with large pressure fluctuations.

3. Strong shock absorption and noise reduction effect

• Spherical ripple design, absorbableAxial, transverse, and angular directionsThree dimensional displacement, compensation amount ± 10mm, suitable for pipeline thermal expansion and contraction and installation deviation.
• The vibration isolation efficiency exceeds 80%, reducing system noise by 12-18 decibels, protecting equipment such as pumps and valves, and extending pipeline life.

4. Easy to install and maintenance free

• No welding or sealant is required. Simply tighten the bolts on the flange, reducing installation time by 50% and making it suitable for construction in narrow spaces.
• Full lifecycle maintenance free, no need to replace gaskets, reducing maintenance costs by 60% and minimizing downtime losses.

• Water supply and drainage/HVACMunicipal water supply, sewage treatment, air conditioning circulating water, pump room shock absorption, non-toxic and environmentally friendly, suitable for drinking water systems.
• Chemical/PetroleumAcid alkali solution, crude oil, fuel transportation, corrosion-resistant material, resistant to chemical erosion.
• Ship/Offshore PlatformSeawater pipelines, LNG transportation, salt spray corrosion environment, anti pull off design adapted to dynamic loads.
• Industrial GeneralPipelines with high vibration and frequent changes in temperature at the inlet and outlet of pumps, fans, and compressors.

Installation Instructions

1. Before installation, check that the sphere is not damaged and the flange surface is free of impurities to avoid scratching the sealing surface.
2. The pipeline should be aligned naturally, and twisting installation is prohibited. The bolts should be evenly tightened diagonally to avoid unilateral force.
3. Use an elastic bracket for overhead use, and add limit bolts to prevent detachment when the pressure is too high.
4. Stay away from sharp metal, avoid piercing the sphere, and do not require additional maintenance after installation.
