THERMAL EXPANSION & CONTRACTION:
The stress developed in CPVC pipes is generally much lesser than developed in a metal pipe for the same temperature, primarily because of the difference in elastic modulus.
CPVC expands when heated and contracts when cooled, like all piping material. CPVC, regardless of the pipe diameter will expand around 25mm per 15m length (1 inch per 50 feet) in length. Necessary provisions should be made to accommodate when it is put into a 23°C temperature increase. Laboratory testing and installation experience have also demonstrated that the practical issues are much smaller than the coefficient of thermal expansion would suggest.
Thermal Expansion is mainly a concern in hot water lines. A long straight run may require an offset or loop. Only one expansion loop, properly sized is required in a single straight run, regardless of its total length. If more convenient, two or more smaller expansion loops, properly sized, can be utilised in a single run of the pipe to accommodate the thermal movement. Also, make sure to hang the pipe with smooth straps that will not restrict the same.
Thermal Expansion Formula:
∆ L = LP C ∆T
Where in,
∆L = Change in length due to change in temperature (in.), Lp = Length of pipe (in.)
C = Coefficient of Thermal Expansion (in./in./ °F) = 3.4 x 10⁻⁵ in./in./ °F for
CPVC Expansion Loop Formula:
L =
Where in,
L = Loop in Length (in.), E = Modulus of Elasticity at maximum temperature (psi),
S = Working Stress at Maximum Temperature (psi), D = Outside Diameter of pipe (in.),
∆L = Change in length due to change in temperature (in.).
PRECAUTIONS:
- The Brush should be clean and dry before commencing the solvent welding process.
- When the system is to be concealed, it should be pressure tested before the concealment.
- Do not attempt cementing in the rain or in the presence of moisture.
- The cement should be used within the expiry period mentioned on the container.
- Keep cement away from all the sources of ignition, heat, sparks and open flame.
- Close the cement container tightly after use.
- Store the solvent cement and piping components in a cool area.
ADDITIONAL INFORMATION
- Use pipes, fittings and solvent cements manufactured by Bandhan Pipes for optimum results.
- Installation process should be carried as per instructions and safe practices must be followed.
- Clean the pipe and fittings with a clean dry cloth to remove any dirt.
- Cut the pipe as square or perpendicular as possible before making a joint.
- Ensure no sharp edges are in contact with the fittings surface while inserting the pipe.
- Ensure proper alignment of pipe and fittings to avoid stress on the joints.
- Ensure installation is done in such a way that there are no chances of air entrapment.
- Always conduct hydraulic pressure testing after installation to detect any leaks and faults.
- Wait for the appropriate cure time before pressure testing. Fill lines slowly and allow air to escape from the system prior to pressure testing.
- Paint pipes exposed to sunlight with a water-based paint.
- Provide additional support to the brass side of CPVC/brass transition or other for keeping any heavy object to support the weight of the metal system.
