The working pressure of a pipe is the maximum pressure it can withstand while still maintaining its structural integrity. This calculation is crucial in ensuring the safe and efficient operation of piping systems in various industries, including oil and gas, chemical processing, and water supply.

Understanding Pipe Materials and Their Limitations

The material of the pipe plays a significant role in determining its working pressure. Different materials have different strength and durability characteristics, which affect their ability to withstand various pressures. For instance, steel pipes are generally stronger and more durable than PVC pipes. When calculating the working pressure, consider the following:
