UPVC Plumbing Pipes ASTMD 1785
UPVC Plumbing Pipes conforming to ASTM D 1785 are rigid, non-toxic, and lightweight pipes made from Unplasticized Polyvinyl Chloride (UPVC). These pipes are specifically designed for cold water plumbing systems, particularly for residential, commercial, and industrial applications. The ASTM D 1785 standard specifies the dimensions, pressure ratings, and material quality for Schedule 40, 80, and 120 pipes used in water distribution systems.
Made from high-quality Unplasticized PVC compound as per ASTM D 1785.
Available in Schedule 40, 80, and 120 pressure ratings.
Suitable for potable water distribution and plumbing.
Resistant to chemical corrosion, scaling, and biological attack.
Lightweight and easy to handle and install.
Smooth inner surface reduces frictional losses.
Excellent mechanical strength and impact resistance.
Classifications:-
UPVC Pipes under ASTM D 1785 are primarily classified based on their wall thickness and pressure-bearing capability, which are divided into Schedules. These schedules are used to standardize the performance of pipes in varying pressure conditions.
Schedule 40: Medium wall thickness – commonly used in household plumbing systems.
Schedule 80: Thick wall – preferred for industrial and commercial applications with higher pressure.
Schedule 120: Extra thick wall – used where very high pressure is involved.
