DN900 RF Large Diameter Rubber Lined Expansion Joint

Product Introduction

Size：DN900

Sealing surface：RF

The large-sized rubber expansion joint with protruding surfaces has some unique characteristics and is widely used in various industrial pipeline systems. Here are some of their characteristics, application scope, and advantages and disadvantages:

Features

1. Large size design: suitable for large pipeline systems, capable of handling larger displacements and absorbing more thermal expansion and contraction.

2. Rubber material: Using rubber as the main material, it has excellent elasticity and can effectively absorb vibration and noise.

3. Raised face design: Raised face flange design enables it to connect pipeline systems more flexibly and adapt to displacement in different directions.

4. High temperature and low temperature resistance: able to adapt to a wide range of temperatures, including high and low temperature environments.

5. Waterproof and dustproof: The sealing performance is good, preventing impurities such as moisture and dust from entering the pipeline system.

Application scope

Large size rubber expansion joints with protruding surfaces are widely used in the following fields:

1. Industrial pipeline system: In large-scale pipeline systems in industries such as chemical, petroleum, natural gas, and power, it is used to compensate for pipeline displacement caused by temperature changes and vibration.

2. Water supply and drainage system: In urban water supply and drainage systems, to adapt to the deformation of pipelines under different working conditions.

3. HVAC system: used in large buildings, factories, and other systems to handle thermal expansion and contraction during system operation.

Advantages and disadvantages

Advantages:

1. Good elasticity: The elasticity of rubber materials can effectively absorb vibration and reduce noise.

2. Strong adaptability: The convex surface design allows it to adapt to multi-directional displacement, improving its adaptability in complex environments.

3. High and low temperature resistance: able to operate normally over a wide temperature range, ensuring the stability of the system.

Disadvantages:

1. Restricted to large systems: Due to its large-sized design, it may not be suitable for small pipeline systems.

2. High cost: Compared to other types of expansion joints, the manufacturing cost of large-sized rubber expansion joints with protruding surfaces may be higher.

When choosing to use large-sized rubber expansion joints with protruding surfaces, it is necessary to comprehensively consider their characteristics and advantages and disadvantages based on specific pipeline system requirements, working environment, and expected displacement situation.
