90° Rubber Joint is a flexible connector in pipeline systems, typically composed of highly elastic rubber material combined with metal flanges. Its primary function is to connect two pipe sections at a 90-degree angle, providing cushioning and sealing effects. The 90° rubber joint can reduce stress caused by temperature changes, geological activities, and other factors, while also absorbing vibrations and reducing noise. It is widely used in water treatment, chemical, petroleum, construction, and other industries.

Structural Composition

The 90° rubber joint consists of an inner rubber layer, reinforcement layer, and outer rubber layer, connected to loose metal flanges or threaded pipe flanges. Its structure includes:

• Inner Rubber Layer: Provides sealing and corrosion resistance.
• Reinforcement Layer: Offers necessary strength and stability.
• Outer Rubber Layer: Protects the inner layers and provides wear resistance.

Working Principle and Application Scenarios

The 90° rubber joint serves the following functions in pipeline systems:

• Cushioning and Sealing: Reduces stress at pipe connections and prevents leakage.
• Vibration Damping and Noise Reduction: Absorbs vibrations, reduces noise, and enhances system operational stability.
• Adaptability to Various Media and Environments: Suitable for various chemical media and complex working conditions, such as acid resistance, alkali resistance, and corrosion resistance.
