What is the maximum working pressure of CSST piping?

The maximum working pressure of corrugated stainless steel tubing (CSST) is indeed a critical specification for ensuring safety and performance in gas piping systems. CSST is designed to handle specific pressure ratings, and it typically operates effectively at lower pressures compared to rigid piping alternatives.

The standard maximum working pressure for CSST piping is usually recognized as 5 psi. This pressure is optimal for the safe delivery of gas while minimizing the risks associated with high-pressure systems, such as leaks or ruptures. In residential and commercial applications, maintaining this lower pressure ensures that the fittings and connections are stable, reducing the likelihood of failures.

Understanding the rated pressure is essential for anyone working with CSST, as exceeding this limit could compromise the integrity of the piping system and lead to hazardous situations. It's important to refer to manufacturer specifications and relevant codes to ensure compliance and safety in gas installations.
