Importance of installing flange covered expansion joint in the pipeline
Due to large change in temperature of the extension tube or corrugated tube, installing flange covered expansion joint is a kind of protective measures. Expansion joint is a new product that connects pumps, valves, pipes and other equipment and pipeline, connected by the bolt, making it a whole, and has certain displacement, convenient installation. It can withstand axial stress of pipeline. So you can adjust it at the time of installation and maintenance, according to the on-site installation size, at work, not only improves work efficiency, but also plays a protective role for pump, valve, and pipeline equipment.
Flange covered expansion joint: after installing covered expansion joints on the pipeline, tighten the nut elastic sealing ring, under the action of nut gland slope, plays a role of sealing and connection press on outer ring of the pipe. When the temperature changes can be in the middle of the joint pipe free of scale, when the foundation sink, the pipe can be skewed, and ensure the sealing with no leakage, to automatically compensate the purpose. Single flange limit expansion joint is suitable for the side with the flange connection, and pipe welding, adjust product when installation ends with the installation of the pipe or flange length, diagonal evenly tighten gland bolts, adjust nut again, so you can let the pipeline within the scope of scale free expansion, locking expansion amount, to the safe operation of pipeline. Double flange limit expansion joint is suitable for both sides with the flange connection, adjust the length of connection on both ends of the product, when installation diagonally evenly tighten gland bolts, adjust limit nut again, so you can make free telescopic pipe, locking, the expansion amount to ensure the safe operation of pipeline. Gland type expansion joint is suitable for both sides and the pipe plug, there is no need to welding, reasonable structure, seal, install quickly and easily.
