2. Expansion joint - Wikipedia

   en.wikipedia.org/wiki/Expansion_joint

   An expansion joint is designed to allow deflection in the axial (compressive), lateral (shear), or angular (bending) deflections. Expansion joints can be non-metallic or metallic (often called bellows type). Non-metallic can be a single ply of rubberized material or a composite made of multiple layers of heat and erosion resistant flexible ...

   EJMA: Expansion Joint Manufacturers Association; CGA: Compressed Gas Association; PCA: Plumbing Code of Australia; Pipes must conform to the dimensional requirements of: ASME B36.10M: Welded and seamless wrought-steel pipe; ASME B36.19M: Stainless-steel pipe; ASME B31.3 2008: Process piping; ASME B31.4 XXXX: Power piping

4. Slip joint - Wikipedia

   en.wikipedia.org/wiki/Slip_joint

   Slip joints are common under conditions where temperature changes can cause expansion and contraction that may overstress a structure. These are generally referred to as expansion joints . Bridges and overpasses frequently have sliding joints that allow a deck to move relative to piers or abutments.

5. Expansion Joint Manufacturers Association - Wikipedia

   The standards are a combination of a variety of expansion joint manufacturers' knowledge and experience. [2] [3] The EJMA organization performs extensive technical research on a variety of topics concerning the design and manufacturing of expansion joints. [4] This knowledge contributes to providing new versions of the EJMA book of standards.

   A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect

7. Interference fit - Wikipedia

   As an example, a 10 mm (0.394 in) shaft made of 303 stainless steel will form a tight fit with allowance of 3–10 μm (0.00012–0.00039 in). A slip fit can be formed when the bore diameter is 12–20 μm (0.00047–0.00079 in) wider than the rod; or, if the rod is made 12–20 μm under the given bore diameter.
