Difference between NP3 Hume Pipe and NP4 Hume pipe

Hume pipes are reinforced concrete pipes that are commonly used for various drainage applications, such as stormwater drainage, culverts, and sewage systems. The term “NP” refers to Non-Pressure type RCC Pipes which are suited for applications where the fluids are not pumped in the pipes at a pressure.

Difference between NP3 and NP4 Hume pipes

Strength: RCC NP4 pipes have a higher load-bearing capacity than NP3 hume pipes due to greater reinforcement. Concrete NP4 pipes are designed to withstand higher traffic loads and heavier loads than NP3 Spun pipes.
Durability: NP4 Hume pipes are more durable and longer-lasting than NP3 pipes. They have a higher resistance to corrosion, abrasion, and other forms of wear and tear, making them ideal for harsh environments or heavy-duty applications.
Cost: RCC Hume NP4 pipes are generally more expensive than NP3 pipes due to their higher strength and durability. However, the cost difference may be justified for applications where higher load-bearing capacity and longer service life are required. Check out RCC NP3 and RCC NP4 Pipe rates.
Application: NP3 Hume pipes are typically used for smaller drainage applications, such as residential or small commercial projects, while NP4 Class RCC pipes are commonly used for larger applications, such as highways, airports, and industrial sites, where higher load-bearing capacity is required.

In summary, NP4 Class Hume pipes are stronger, more durable, and better suited for heavy-duty applications than NP3 RCC Cement pipes. The choice between the two will depend on the specific needs of the project and the load-bearing requirements of the application.

It can be further noted that NP3 Hume pipe and NP4 Hume pipe has exact same thickness but greatly vary in amount of steel present inside.

FAQ

What is Hume Pipe?

Hume pipe is used for drainage, sewage system, irrigation and underground wire laying system. Hume pipes are made up of reinforced concrete making them durable and capable of bearing heavy load.

What is the difference between RCC pipe and Hume pipe?
