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.

If you wish to succeed, you should use persistence as your good friend, experience as your reference, prudence as your brother and hope as your sentry.

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
