2. Crevice corrosion - Wikipedia

   en.wikipedia.org/wiki/Crevice_corrosion

   Depending on the environment developed in the crevice and the nature of the metal, the crevice corrosion can take a form of: pitting (i.e., formation of pits), but note pitting and crevice corrosion are not the same phenomenon, [8] filiform corrosion (this type of crevice corrosion that may occur on a metallic surface underneath an organic ...

3. Corrosion loop - Wikipedia

   en.wikipedia.org/wiki/Corrosion_loop

   Corrosion loop(s) are systematized analysis "loops" used during Risk-based inspection analysis. Both terms “RBI Corrosion loops” or “RBI corrosion circuits” are generic terms used to indicate the systematization of piping systems into usable and understandable parts associated with corrosion.

4. Aluminium joining - Wikipedia

   en.wikipedia.org/wiki/Aluminium_joining

   Aluminium alloys are often used due to their high strength-to-weight ratio, corrosion resistance, low cost, high thermal and electrical conductivity.There are a variety of techniques to join aluminium including mechanical fasteners, welding, adhesive bonding, brazing, soldering and friction stir welding (FSW), etc. Various techniques are used based on the cost and strength required for the joint.

5. Fretting - Wikipedia

   en.wikipedia.org/wiki/Fretting

   Fretting refers to wear and sometimes corrosion damage of loaded surfaces in contact while they encounter small oscillatory movements tangential to the surface. Fretting is caused by adhesion of contact surface asperities, which are subsequently broken again by the small movement. This breaking causes wear debris to be formed.

6. Crimp (joining) - Wikipedia

   en.wikipedia.org/wiki/Crimp_(joining)

   Circular connectors using crimp contacts can be classified as rear release or front release, referring to the side of the connector where the pins are anchored: [19] Front release contacts are released from the front (contact side) of the connector, and removed from the rear. The removal tool engages with the front portion of the contact and ...

7. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   The bodies of fittings for pipe and tubing are often the same base material as the pipe or tubing connected: copper, steel, PVC, CPVC, or ABS. Any material permitted by the plumbing, health, or building code (as applicable) may be used, but it must be compatible with the other materials in the system, the fluids being transported, and the ...

8. Galvanic anode - Wikipedia

   en.wikipedia.org/wiki/Galvanic_anode

   In brief, corrosion is a chemical reaction occurring by an electrochemical mechanism (a redox reaction). [1] During corrosion of iron or steel there are two reactions, oxidation (equation 1), where electrons leave the metal (and the metal dissolves, i.e. actual loss of metal results) and reduction, where the electrons are used to convert oxygen and water to hydroxide ions (equation 2): [2]

9. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   Aluminum conduit, similar to galvanized steel conduit, is a rigid tube, generally used in commercial and industrial applications where a higher resistance to corrosion is needed. Such locations would include food processing plants, where large amounts of water and cleaning chemicals would make galvanized conduit unsuitable.
