FAQS

* What’s the main difference between uPVC pipe fittings & PVC pipe fittings?
A: There is only one difference between PVC and uPVC and that is that PVC contains BPA and phthalates, which are two plasticizers that make it more flexible. The "u" in uPVC stands for "unplasticized," and because it doesn't have these extra materials, uPVC is often called rigid plastic.
Because of its rigidity, uPVC is a better construction material than PVC. The plasticizing materials in PVC toxic, although it is very low, so PVC pipes & fittings are undesirable for transporting residential water for drinking. uPVC pipes & fittings don’t include any toxic plasticizers, so they are suitable for drinking water transportation.
* What’s the max. Working pressure of uPVC gasketed fittings? How about the max. Working temperature?
A: SUNPLAST uPVC gasketed fittings are designed and manufactured to GB/T10002.2-2003, ISO 4422-3:1996, ISO 1542-3:2009 standards and rated for a maximum internal pressure of PN10 bars at 20℃.
The uPVC pipe fittings are suitable for COLD water only, the maximum recommended operating temperature is 60℃.
* Are uPVC pipe fittings UV-resistant?
A: uPVC is an extremely versatile product that has uses ranging from drinking water to highly corrosive chemical applications. The product contains UV stabilising additives and thermal properties which ensure that it is suitable for both interior and exterior environments.
* For the buried PVC waster pipe, should I use solvent weld joint fittings? Or rubber ring gasket fittings?
A: Typically, uPVC rubber ring fittings are used for larger diameter pipes (4 inch and larger) where the runs consist of longer distances with a low density of fittings. Examples would be outside of the building civil work and inside (below grade) storm drainage.
When you have smaller diameter pipes and a high density of fittings, such as a bathroom group, uPVC solvent joint fittings would be used.
