PVC-U Screen and Casing Pipes for Bore/Tubewell – IS 12818 | BIS Procedure & Documentation
In India’s rapidly growing
infrastructure and agricultural sectors, borewells and tubewells play a crucial
role in ensuring access to groundwater. To support this, Unplasticized
Polyvinyl Chloride (PVC-U) screen and casing pipes are widely used due to their
durability, corrosion resistance, and cost-effectiveness. However, ensuring the
quality and safety of these pipes is paramount. This is where the BIS
certification for PVC-U screen and casing pipes becomes essential.
The Bureau of Indian Standards (BIS)
is the national body responsible for standardizing and quality-certifying
products in India. When a product meets the required Indian Standard, it is
granted a BIS license and allowed to bear the ISI mark, a symbol of trust,
safety, and quality.
Indian Standard IS 12818
for PVC-U Screen and Casing Pipes
The Indian Standard for PVC-U screen
and casing pipes designed for borewells and tubewells is IS 12818. This
standard includes specifications, testing methods, dimensions, and performance
criteria that these pipes must meet to ensure safety and durability in
groundwater extraction. It ensures that the pipes maintain their structural
integrity under soil pressure and varying water flow conditions.
IS 12818 classifies PVC-U casing and
screen pipes into the following categories:
- CM (Casing Medium) – suitable for
medium-depth borewells
- CS (Casing Shallow) – intended for
shallow-depth borewells
- RS (Ribbed Screen) – designed for
use as screens in tubewells
- PL (Plain Screen) – used as screens
where slots are not required
Each category must adhere to specific
requirements for material composition, mechanical properties, and physical
dimensions.
