what is difference of NP3 and NP4 pipe and what is the thickness of 1000mm dia NP4 pipe..

Answer / jaya kumar

Hume pipes are available in three grades NP2, NP3, and NP4. The major difference between NP2, NP3, and NP4 RCC pipes is the load-bearing quality and flow. NP 2 RCC pipes are used for low duty load, NP 3 RCC pipes are used for medium-duty load, and NP 4 RCC pipes are used for heavy-duty load.
