High-Pressure Resistant Large-Diameter BF Single Flange Loose Sleeve Limit Expansion Joint
Product Introduction
The single flange expansion joint is composed of loose sleeve expansion joints and limit stub pipes. It can prevent the leakage or damage of the compensating joint caused by excessive displacement of the pipeline, and is mainly used for the loose pipe connection that absorbs axial displacement and bears pressure thrust within the allowable displacement range.
Product Advantages
1. Compensate for pipeline displacement
2. Withstand pressure thrust
3. Prevent excessive displacement
4. Absorb vibration and reduce noise
5. Adapt to a variety of media transportation
6. Easy to install
7. Abrasion resistance and corrosion resistance
The medium for which the product is suitable
1. Seawater, freshwater
2. Hot and cold water, drinking water, domestic sewage
3. Crude oil, fuel oil, lubricating oil, refined oil
4. Air, gas and steam and granular powder and other media with a temperature not higher than 250 degrees
