NP refers to Non Pressure pipes. They do not have a pressure rating and are suitable for conveying a liquid only by gravity (ex: irrigation, culverts, water drainage etc) or telephone/TV/electrical cable protection.

Basic Difference between NP2, NP3 & NP 4 is due to quality
of product. Thichness is not main difference , NP 2 is
used for normal flow and condition, NP 3 & NP 4 is used for
heavy work for durability also prefer higher class
