Answer 2

Explanation:

Reinforced concrete pipes used in water supplies are classified as P1, P2. and P3 with a test pressure of 2.0, 4.0, and 6.0 Kg/cm2 respectively. For use on gravity mains, the working pressure should not exceed 2/3 of the test pressure.

How do you measure the strength of a pipe?

1. Testing methods: Strength and resistance
2. Creep rupture strength - Internal pressure test. Constant internal pressure at a constant temperature.
3. Stress crack resistance - Pipe notch test. Slow crack growth testing.
4. Resistance to Rapid Crack Propagation - S4 Test.
5. Creep rupture strength - Internal pressure test.
