EN 1092-2 Cast Iron Carbon Steel Telescopic Concentric Reducer Rubber Joints

Concentric reducer rubber joint structure

1. Inner rubber layer: The inner rubber layer is the inner layer of concentric reducer rubber joints, which is usually made of rubber material and has good elasticity and sealing properties.
2. Fabric reinforcement layer: The reinforcement layer is composed of multiple layers of squeegee nylon cord, which is used to increase the strength and pressure resistance of the joint.
3. Intermediate rubber layer: The middle rubber layer is located between the inner rubber layer and the outer rubber layer, which plays the role of buffering and protection.
4. Cover: The coverer is the outer layer of the joint, which is also made of rubber material to provide protection and weather resistance.
5. End reinforcement metal ring or wire traveler: Used to enhance the end strength of the joint and prevent damage.
6. Loose metal flange: The joint is connected with the pipe through the loose metal flange to provide a stable connection and sealing effect.

Product performance characteristics

1. Strong pressure resistance: The internal density of the joint is high, the pressure resistance is strong, and it can withstand high working pressure, such as 0.6MPa and 1.0MPa.
2. Good elasticity: The joint has good elasticity, which can produce lateral, axial and angular displacement during installation, and adapt to the misalignment of the pipeline and the condition that the flange is not parallel.
3. Shock absorption and noise reduction: It can reduce the noise transmitted by the structure when working, has a good vibration absorption ability, and is suitable for various pipeline compensation, especially in large pipelines and long-distance transportation pipelines.
4. Small size and light weight: The joint is small in size, light in weight, easy to install and maintain, and easy to transport and construct.

Product application field

1. HVAC system: In HVAC system, reducer rubber joints can be used to connect pipes of different diameters to ensure the smooth transmission of hot and cold water, steam and other media, while reducing vibration and noise.
2. Petroleum industry: In the petroleum industry, reducing rubber joints can be used to connect pipeline systems in oil wells, refineries and other places to ensure the safe transmission of oil and other media.
3. Fire protection system: In the fire protection system, reducing rubber joints can be used to connect fire pumps, fire pipes and other equipment to ensure the normal operation of the fire protection system in an emergency.
4. Smelting furnace system: The pipes in the smelting furnace system need to withstand the effects of high temperature and vibration. Reducer rubber joints can absorb vibration and shock, protect the normal operation of pipelines and equipment, and extend the service life of equipment.

Product parameters

Product installation precautions

1. The direction of the joint: Ensure that the direction of the joint is consistent with the direction of the pipe or equipment connection during installation, so as to avoid leakage or performance degradation caused by installation errors.
2. Flange connection: Ensure that the bolts at the flange connection are tightened evenly to avoid air leakage or loosening.
3. Expansion margin: During installation, it is necessary to set aside a certain amount of rubber joint expansion margin to adapt to the vibration and thermal expansion and contraction of the pipeline during use.
4. Bending radius: Avoid overstretching or twisting the rubber joint during installation to ensure its service life and performance.
5. Ambient temperature: Pay attention to the temperature of the working environment during installation, and avoid installation under extreme temperature conditions.
