what is the difference between np2, np3 & np4 rcc pipes

Answer Posted / deep kotadiya

Basically on field terms the difference to understand its usage is
NP stands for non pressure
And NP 2, NP 3, NP 4 are categories of pipe to be layed according to the demand, factors including depth, load and volume or flow in the pipe.
NP 2 for shallow depth and least flow
NP 3 has more steel than NP 2 and can be layed in more depth
NP 4 more steel than NP 3 in order to resist in deeper depth and max. Load
All pipes works economically under the gravitational force, still pump house are there in order to tackle difficulties.
