What is the allowable maximum PSI for a piping system made of ASTM C-857?

The allowable maximum PSI for a piping system made of ASTM C-857 is 250 psi. ASTM C-857 refers to the standard specification for Reinforced Concrete Pressure Pipe for Water and Other Liquids. This standard establishes the specifications that ensure the structural integrity and performance of the pipeline when subjected to pressure.

In the specific case of this material, reinforced concrete pressure pipe is designed for various applications, taking into account the necessary parameters such as wall thickness, reinforcement, and the type of fluid being transported. The 250 psi rating reflects the strength and resilience of this type of piping under normal operating conditions, which includes considerations for factors like temperature, pressure fluctuations, and material fatigue.

Operating above this maximum pressure could lead to failure modes such as cracking or bursting of the pipe, potentially resulting in severe safety hazards and environmental issues. Understanding these limits is crucial for the safe and efficient design of piping systems in accordance with relevant codes and standards.
