B2F double flange type limit expansion joint is suitable for connecting both sides with flange. AF type flange loose end expansion joint is a loose joint connecting pipe consisting of body, seal ring and pressing member. Mainly used for compensating joints that absorb displacement and cannot withstand pressure thrust.
Working principle: After the loose sleeve expansion joint is installed on the pipeline, tighten the elastic sealing ring of the nut, and under the action of the nut gland, rely on the mutual inclination to press and seal the outer ring of the pipe. When the temperature changes, the pipe can freely expand and contract in the middle of the joint, the local base sinks, the pipe can be deflected, and the seal is ensured without leakage, thus automatically compensating.
The CF type single flange type force transmission joint is composed of a body, a sealing ring, a gland, and a short pipe flange member. It is suitable for one side to be connected to the flange and welded to the pipe. The installation is to adjust the installation length of the two ends of the product and the pipe or flange. After the installation and welding, the gland bolts are evenly tightened once at a diagonal angle, and they become one, and have a certain amount of displacement, which is convenient for installation and maintenance, according to the site size. Make adjustments. The axial thrust can be transmitted to the entire pipe during operation.
