DN900 RF Large Diameter Rubber Lined Expansion Joint

Product Introduction

Size: DN900

Sealing surface: RF

Large rubber expansion joints are commonly used in larger diameter pipeline systems to handle temperature changes, vibrations, expansion, and contraction in pipelines.

The design of these expansion joints aims to provide the flexible support required for the pipeline system to absorb motion and deformation in the system.

Features

1. Large diameter:

This type of expansion joint is suitable for large diameter pipeline systems above DN500, and its large size ensures that the expansion joint can handle a larger range of displacement and expansion.

2. Rubber material:

The main material for large-sized rubber expansion joints is usually rubber or similar elastic materials, such as Neoprene, Nitrile, natural rubber, etc. These materials have superior elasticity, which helps to absorb vibration and deformation.

3. Outer structure:

The outer layer of the expansion joint is usually composed of metal or other reinforcing materials, used to provide structural support, protect the inner rubber layer, and withstand certain pressure when needed.

4. Corrosion resistance:

Rubber materials themselves usually have a certain degree of resistance to corrosive media, but when dealing with applications with special corrosive requirements, more corrosion-resistant rubber types can be selected, or special protective layers can be added.

5. High temperature resistance:

For high-temperature environments, high-temperature resistant rubber materials can be selected to ensure elasticity and performance at high temperatures.

6. Sealing performance:

Rubber expansion joints with inner lining provide better sealing performance, suitable for pipeline systems that require high sealing performance.

7. Multidirectional displacement:

The large-sized rubber expansion joint is designed to be able to experience displacement in multiple directions, including axial, lateral, and angular displacement.

Applicable scope

This type of expansion joint is suitable for large industrial pipeline systems, such as water supply systems, heating systems, refrigeration systems, etc., to handle temperature changes, vibration, and other motion factors.

When selecting large-sized rubber expansion joints, it is necessary to carefully consider the working conditions, medium characteristics, temperature range, and pressure requirements of the pipeline system. Collaborate with professional pipeline engineers or manufacturers to ensure that the selected expansion joints meet the requirements of the application and provide the required performance.
