2. Polyvinyl chloride - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_chloride

   Traditional product PVC has a maximum operating temperature around 60 °C (140 °F) when heat distortion begins to occur. [35] As a thermoplastic, PVC has an inherent insulation that aids in reducing condensation formation and resisting internal temperature changes for hot and cold liquids. [35]

3. Chlorinated polyvinyl chloride - Wikipedia

   en.wikipedia.org/wiki/Chlorinated_polyvinyl_chloride

   CPVC can withstand corrosive water at temperatures greater than PVC, typically greater by 40–50 °C (greater by 72–90 °F), contributing to its popularity as a material for water-piping systems in residential and commercial construction. CPVC maximal operating temperature peaks at 200 °F (93 °C).

4. Cross-linked polyethylene - Wikipedia

   en.wikipedia.org/wiki/Cross-linked_polyethylene

   A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.

5. Operating temperature - Wikipedia

   en.wikipedia.org/wiki/Operating_temperature

   An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...

6. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   For piping built to ASME B31.3, if the design temperature is greater than the test temperature, then the test pressure must be adjusted for the related allowable stress at the design temperature. This is done by multiplying 1.5 MAWP by the ratio of the allowable stress at the test temperature to allowable stress at the design temperature per ...

7. Heat-shrink tubing - Wikipedia

   en.wikipedia.org/wiki/Heat-shrink_tubing

   Its operating temperature range is -50 to 200 °C [citation needed] PTFE (fluoropolymer) tubes have a wide operating temperature range (-55 to 175 °C), a low coefficient of friction, and high resistance to chemicals and punctures. [7] Viton, another fluoropolymer with high chemical resistance, is widely used in hydraulic equipment. It is ...
