Move Axially Double Flange Transmission Joint

Double flange limit expansion joint

 

The double flange limit expansion joint is composed of body, sealing ring, gland, expansion short pipe and other main components. On the basis of the original performance of the loose expansion joint, a limit device is added, and the maximum expansion is locked with double nuts. The pipeline can expand freely in the allowable expansion amount. Once it exceeds its maximum expansion amount, it will play a limit to ensure the safe operation of the pipeline. It is especially suitable for the connection in the pipeline with vibration or certain inclination and turning.

 

Performance of double flange limit expansion joint

 

1. It has high compression capacity to ensure the operation of the pipeline during crustal movement. High corrosion resistance, expansion joints are buried underground all year round, and high corrosion resistance is required.

2. It can move axially to eliminate the thermal expansion and cold contraction stress caused by seasonal changes or different media. The steel expansion joint is made of steel, and the rubber joint has strong corrosion resistance and flange connection.

3. Easy installation and maintenance, avoiding unnecessary trouble in the welding process. Special design process is adopted to strengthen the limit bolt to make the pipeline operation more reliable.

Note:Double flange limit expansion joint is suitable for connecting both sides with flange. During installation, adjust the connecting length of both ends of the product, tighten the gland bolts in turn and adjust the limit nuts. In this way, the pipeline can expand freely, lock the expansion, and ensure the safe operation of the pipeline.

Double flange limit expansion joint advantage

 

1. The product price is the ex factory price.

2. 18 years of manufacturing experience and 5 years of export experience.

3. Strict quality inspection, the quality far exceeds the industry standard.

4. The mold has a variety of specifications and supports customization and OEM.

5. Provide samples free of charge

6. There is a large amount of inventory.

 

Double flange limit expansion joint application

 

In the installation process of double flange limit expansion joint, when the temperature changes or the pipeline vibrates, it can play the role of expansion compensation. In case of leakage, the displacement of the seal can not be compensated. Secondly, the installation and disassembly of the product is very convenient, making it connected with the water supply and drainage pipeline and water tower, which provides great convenience for the installation and disassembly of the water pump and water meter.
