Introduction: After the loose sleeve expansion joint is installed on the pipeline, the nut elastic sealing ring is tightened, and with the help of mutual slope under the effect of nut gland, it is pressed on the outside of water pipe for sealing and connection. When the temperature changes, the water pipe can freely expand and expand in the middle of the connector. When the foundation sinks, the water pipe can

Loose sleeve Expansion joint After being installed on the pipe, the nut elastic sealing ring is tightened, and with the help of mutual slope under the effect of nut gland, it is pressed on the outside of water pipe for sealing and connection. When the temperature changes, the water pipe can freely expand and expand in the middle of the connector. When the foundation sinks, the water pipe can tilt and ensure no leakage of the seal, so it has the purpose of automatic compensation.
AF type flange loose sleeve expansion joint is a kind of equipment which is composed of body, sealing ring and clamping prefabricated components. While the pressure of the joint can be compensated without absorbing the thrust. Working principle: the loose sleeve expansion joint is installed after the pipe, and the nut elastic sealing ring is tightened. Under the effect of the nut gland, with the help of mutual inclination, it is pressed on the outer ring of the water pipe for sealing and connection. When the temperature changes, the water pipe can freely expand and expand in the middle of the connector. When the foundation sinks, the water pipe can tilt and ensure the sealing without leakage, which has the purpose of automatic compensation.
CF type single flange type Force transfer joint It is composed of itself, sealing ring, gland, short pipe flange component. It is suitable to be connected with flange and welded with pipe at the same time. Installation is to adjust the installation length between the two sides of the product and the pipeline or flange. After installation and welding, the top corner is uniformly tightened with gland bolts at one time, and it is combined into one with a certain displacement, which is convenient for installation and maintenance, and can be adjusted according to the on-site specifications. The radial resistance can be transmitted to the whole pipe during operation.
AF type flange loose sleeve expansion joint is suitable for conveying sea water, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and particulate matter powder with temperature not higher than 250 ℃. Expansion joint series products are metal products, which have high tensile and compressive strength, superior soft sealing performance and convenient loading and unloading. They are widely used in power engineering, metallurgical industry, chemical plant, water supply and drainage and sewage treatment and other manufacturing industries. They are mainly used for the connection between water pump and gate valve and pipeline. The connection of the pipe is simple and quick. It is suitable for one side of flange connection and the other side of pipe insertion.
