Expansion Joints are designed to withstand and adjust to extreme pressure and temperature ranges within systems that are exposed to these elements on a regular basis. You can find these in buildings, pipes, bridges and other structure types where joints are needed. They are a key factor in the longevity and security to prevent unnatural cracking and breaking providing flexibility with limited movement. These also extend the life and lower the maintenance needs for these areas allowing personnel to focus on more sensitive issues and hardware. There are a variety of  different kinds of joints  but each is specifically designed for individual purposes and tasks. As a contractor when you purchase, you need to ensure that you buy the exact type that is made for the project you are working on. Ask about pricing, their inspection process and shipping and only ever deal with companies that have a reputation for supplying quality equipment. The Hinged Expansion Joint, or  hinged bellows , is us

The installation procedures, steps and methods of   metal bellows   are as follows. 1. first measure the full length of the prepared metal expansion joint (including the connecting flange), draw the centerline of the positioning of the metal expansion joint installed on the pipeline, and draw the edge line of the bellows expansion joint according to the drawing. (The length of the bellows expansion joint (to the edge of the connecting flange)). 2. Cut the pipe according to the line, and consider the length of the flange and gasket when connecting the flange. 3. Connect the bellows expansion joint with welded interface: support the bellows expansion joint with temporary support hanger for centering. Both sides of the bellows expansion joint interfaces should be aligned and spot welded at the same time. After checking the correct position of the bellows expansion joint, carry out welding in turn. 4. connecting the bellows  expansion joint  of the flange interface: first two flange gasket

Universal Hinge Ripple Compensator Product Description TWJ universal hinge ripple compensator  is also called universal hinge corrugated expansion joint and universal hinge corrugated expansion joint. The hinge corrugated compensator is used in conjunction with two or three compensators (a single hinge compensator has no compensation capability). It can compensate the angular displacement in any plane of the pipeline. Purpose: The expansion joint  has a universal ring, and there are two pairs of mutually perpendicular hinge structures in the circumferential direction of the universal ring, so it can absorb the angular displacement of any plane. Usually when absorbing displacement, two or three combinations should be used. Model: DN100-DN3000 produced by our company Pressure level: 0.1Mpa-2.5Mpa Connection mode: 1. Flange connection type 2.
