Assembly

  • a. Dry fitment – check joint of pipe to fitting without solvent cement should fit up to 60 – 70%

  • b. Cold fusion joint (cold welded joint)

  • c. For diameters ½” to 2”, single step solvent cement.

  • d. For diameters 2½” to 4”, 2 step solvent cement (Primer + Solvent Cement)

  • e. Primer helps to clean the surface of pipe & fitting and softens the material.

  • f. Set time – After application of solvent cement, it takes some time for the joint to set, subject to atmospheric conditions and pipe diameter

Average initial set schedule for CPVC solvent cement

Temperature Range Pipe size ½” – 1¼” (20mm – 40mm)
16⁰ – 38⁰C 2 minutes
5⁰ – 16⁰C 5 minutes
– 18⁰ – -5⁰C 10 minutes

  • g. Cure time – Curing time is longer time than the set time. Curing means the joint has completely matured.  

    Average joint cure schedule for uPVC solvent cement
    Relative Humidity 60% or less Pipe size ½” – 1¼”  (20mm – 40mm)
    Temperature ranges during assembly & cure periods Bar
    up to 11 11 to 26)
    16⁰ – 38⁰C 15 minutes 6 hours
    5⁰ – 16⁰C 20 minutes 12 hours
    – 18⁰ – -5⁰C 30 minutes 48 hours

  • h. The pressure test can only be performed after the joint is completely cured.

  • i. Compressed air cannot be used for leakage test.

  • j. In case of using paint on UPVC piping system, only Latex based paints which are water based paints wherein the paint concentrate is diluted with water to make it workable and brush able. NO OIL / Solvent based paints are to be used as these paints can drastically reduce the life of the systems.
