  2. Expansion joint - Wikipedia

    en.wikipedia.org/wiki/Expansion_joint

    A expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials. They are commonly found between sections of buildings , bridges , sidewalks , railway tracks , piping systems , ships , and other structures.

  3. Refractory lined expansion joint - Wikipedia

    en.wikipedia.org/wiki/Refractory_lined_expansion...

    A Refractory lined expansion joint is an assembly used in a pipe line to allow it to expand and contract [1] as climate conditions move from hot to cold and helps to ensure that the system remains functional. The refractory-lining can be vibra cast insulation with anchors, abrasion resistant refractory in hex mesh, gunned insulating refractory ...

    Pipe welding is often performed by specially licensed workers whose skills are retested periodically. For critical applications, every joint is tested with nondestructive methods. Because of the skills required, welded pipe joints are usually restricted to high-performance applications such as shipbuilding, and in chemical and nuclear reactors.

    en.wikipedia.org/wiki/Joint_(building)

    A building joint is a junction where building elements meet without applying a static load from one element to another. When one or more of these vertical or horizontal elements that meet are required by the local building code to have a fire-resistance rating, the resulting opening that makes up the joint must be firestopped in order to restore the required compartmentalisation.

    en.wikipedia.org/wiki/Toroidal_expansion_joint

    Toroidal Expansion Joint - U.S. Bellows, Inc. A Toroidal expansion joint is a metallic assembly that consists of a series of toroidal convolutions which are circular tubes wrapped around pipe ends or weld ends and have a gap at the inside diameter to allow for axial stroke while absorbing changes in expansion or contraction of the pipe line.
