Difference between NP2 pipe and NP4 pipe

When it comes to NP2 and NP4 RCC pipes, the main difference lies in their load- bearing capacities . NP2 pipes are designed for lighter loads, while NP4 pipes are built to handle heavier loads. This means that NP4 Hume pipes are generally used in areas where there is a higher risk of heavy traffic or soil pressure. Some distinctive characteristics that set them apart are:

1) Load-Bearing Capacity:

NP2 Pipes: These pipes are designed to handle lighter loads, making them suitable for residential drainage systems and smaller infrastructure projects.

NP4 Pipes: On the other hand, NP4 pipes are built to withstand heavier loads, making them ideal for large scale projects like sewer system and stormwater management.

2) Durability:

NP2 Pipes: While NP2 pipes are durable, they are not as robust as NP4 pipes. They are still a reliable choice for areas with lower traffic and soil pressure.

NP4 Pipes: NP4 pipes are designed to be more resilient and can endure greater pressure and traffic, making them suitable for areas with heavy usage and higher soil pressure.

3) Applications:

NP2 Pipes: Common applications of NP2 pipes include residential drainage, agricultural fields, and small infrastructure projects.
