2. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   In older installations, the threaded brass pipe was similarly used and was considered superior to steel for drinking water because it was more resistant to corrosion and shed much fewer residues into the flowing water. Assembling threaded pipe is labor-intensive, and requires skill and planning to allow lengths of pipe to be screwed together in ...

3. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   The most common process pipe joint is the butt weld. The ends of pipe to be welded must have a certain weld preparation called an End Weld Prep (EWP) which is typically at an angle of 37.5 degrees to accommodate the filler weld metal. The most common pipe thread in North America is the National Pipe Thread (NPT) or the Dryseal (NPTF

4. Heat fusion - Wikipedia

   en.wikipedia.org/wiki/Heat_fusion

   Socket fusion joins pipe and fittings together, rather than simply joining pipe to pipe. It requires less pressure than butt-welding and is more commonly used on smaller sizes of pipe (4" or less). Socket welding has additional advantages of requiring less machinery and is more portable than the heavier equipment required for butt fusion. [7]

5. Electrofusion - Wikipedia

   en.wikipedia.org/wiki/Electrofusion

   Electrofusion is a method of joining MDPE, HDPE and other plastic pipes using special fittings that have built-in electric heating elements which are used to weld the joint together. The pipes to be joined are cleaned, inserted into the electrofusion fitting and then alignment clamps and a voltage (typically 40V) is applied for a fixed time ...

6. Oxy-fuel welding and cutting - Wikipedia

   In jewelry production for "water welding" using a water torch (an oxyhydrogen torch whose gas supply is generated immediately by electrolysis of water). In automotive repair, removing a seized bolt. Formerly, to heat lumps of quicklime to obtain a bright white light called limelight, in theatres or optical ("magic") lanterns.

7. 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
