BF single flange loose sleeve limit expansion joint

Product Features

1. Convenient and quick installation: The joint adopts a composite installation method of flange connection at one end and pipeline welding at the other end. It is suitable for pipeline systems with vibration or slope changes. It is widely used in water supply and drainage pipelines, water towers, water pumps and other equipment. The temperature difference expansion problem of long-distance pipelines can be adjusted.

1. Reliable sealing: The single-flange loose sleeve limit expansion joint is composed of a loose sleeve expansion joint and a limit short tube, which can efficiently absorb axial displacement and bear pressure thrust within the allowable displacement range to prevent leakage or damage of the compensation joint due to excessive displacement of the pipeline.

2. Easy maintenance: The design of the joint makes the disassembly and assembly of the valve more convenient, which is conducive to the maintenance and maintenance of the equipment.

3. Wide range of application: suitable for transporting seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas and other media, steam and granular powder media with a temperature not higher than 250 degrees.

4. Structural features: The single-flange loose sleeve limit expansion joint realizes the convenient connection of flange connection on one side of the pipeline and inconsistency of welding on the other. During installation, adjust the installation length between the two ends of the product and the pipeline or flange, tighten the gland bolts evenly diagonally, and then adjust the limit nut, so that the pipeline can freely expand and contract within the range of expansion and contraction, lock the expansion and contraction, and ensure the safe operation of the pipeline.
