2. Compression fitting - Wikipedia

   en.wikipedia.org/wiki/Compression_fitting

   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

3. Erosion corrosion of copper water tubes - Wikipedia

   en.wikipedia.org/wiki/Erosion_corrosion_of...

   It is not generally realised how great an effect small obstructions can have on the flow pattern of water in a pipe-work system and the extent to which they can induce turbulence and cause corrosion-erosion. For example, it is most important, as far as possible, to ensure that copper tubes cut with a tube cutter are deburred before making the ...

4. 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 ...

5. Cured-in-place pipe - Wikipedia

   en.wikipedia.org/wiki/Cured-in-place_pipe

   The process of CIPP involves inserting and running a felt lining into a preexisting pipe that is the subject of repair. Resin within the liner is then exposed to a curing element to harden it and make it attach to the inner walls of the pipe. Once fully cured, the lining now acts as a new pipeline.

6. Cold water pitting of copper tube - Wikipedia

   en.wikipedia.org/wiki/Cold_water_pitting_of...

   Copper tubes have been used to distribute potable water within building for many years and hundreds of miles are installed throughout Europe every year. The long life of copper when exposed to natural waters is a result of its thermodynamic stability, its high resistance to reacting with the environment, and the formation of insoluble corrosion products that insulate the metal from the ...

7. CISBOT - Wikipedia

   en.wikipedia.org/wiki/CISBOT

   CISBOT is introduced into a pipeline through a 5-by-5-foot (1.5 m × 1.5 m) hole and can repair the joints with an anaerobic sealant for a distance of 1,500 feet (460 m) while the pipe is still in operation. External repair without the robot would require the arranging of temporary gas supply to customers through tanks, purging the pipeline of ...
