ASME B16.5 (LJ) loose flange

The main function of a loop flange is to connect pipelines and equipment, and it can slide freely on the pipeline, making it convenient for pipeline installation and disassembly. Loop flanges are commonly used in pipeline systems that require frequent disassembly and cleaning, such as in industries such as chemical, petroleum, and natural gas.

The advantages of loop flanges include:

Easy installation: The loop flange does not require welding and can be directly installed on the pipeline and then fixed with bolts, making installation very convenient.

Good disassemblability: The loop flange can be disassembled at any time, making it convenient for pipeline maintenance and replacement.

Strong adaptability: The loop flange can adapt to different pipeline sizes and pressure levels, so its application range is very wide.

Good sealing performance: The loop flange is sealed with a sealing gasket, which has good sealing performance and can effectively prevent leakage.

It should be noted that the thickness of the loop flange is relatively large, and it is only suitable for situations where the container or pipeline lining has brittle materials and the pressure is not high. When selecting a looping flange, it is necessary to comprehensively consider factors such as pipeline size, pressure rating, and medium to ensure the selection of a suitable flange type.
