What is the standard pressure for testing a new line?

The standard pressure for testing a new line is 150 psi. This value is commonly used in various industry standards and guidelines to ensure the integrity of new piping systems before they are put into service. Testing at this pressure level helps to identify any potential leaks or weaknesses in the materials and joint fittings.

In testing scenarios, 150 psi is typically sufficient to simulate operational conditions and assess the performance of the line under pressure without excessively compromising the design and material limits. This pressure level strikes a balance between safety and the ability to detect faults, ensuring that systems can handle typical working pressures while also being tested for resistance to bursts and leaks.
