uPVC
uPVC pipes and fittings used in sewage treatment plants should be made from unplasticized
polyvinyl chloride (uPVC) material, as specified in the European standard.
The design of uPVC pipes and fittings should be in accordance with the requirements outlined
in the standard, ensuring proper functionality and compatibility with sewage treatment plant
systems.
pipes and fittings are commonly used in sewage treatment plants due to their durability,
corrosion resistance, and long service life. They are also lightweight, making them easy to
handle and install in various sewage treatment plant systems. Additionally, uPVC pipes and
fittings have smooth internal surfaces, which reduce friction and allow for efficient flow of
wastewater, contributing to the overall effectiveness of the sewage treatment process.
UPVC (Unplasticized Polyvinyl Chloride) material is recommended to be used in various low
and medium pressure applications such as drain systems, chemical systems, and waste air
systems. In Compliance to relevant standards such as ASTM D1785, ISO 4422, and IS 4985.
UPVC pipes are available in a range of sizes and schedules to accommodate different flow rates
and pressure requirements in sewage treatment systems. The pipe size and schedule should
be selected based on the design flow rates, pressure conditions, and system layout. And the
nominal pipe wall thicknesses according to BS EN ISO 1452-2.
Pipes shall have a standard dimension ratio (SDR) of SDR11 for PN16 and SDR17 for PN10
HDPE pipes, and available in various sizes.
Solvent cement jointing is used for UPVC piping systems in sewage treatment plants due to its
ease of installation and leak-free performance.
