For what maximum duration is a Proof Pressure Method valid in years?

The Proof Pressure Method is a testing procedure used to assess the integrity of pressure vessels and piping systems. Under current guidelines, the maximum duration for which this method remains valid is seven years. This validity period ensures that equipment is regularly evaluated for safety and performance, allowing for timely maintenance or replacement as necessary to prevent failures or accidents.

Maintaining a seven-year validity reflects best practices in safety and compliance within the gas industry, ensuring that equipment operates effectively and minimizes risks associated with leaks or structural failures. Regular re-evaluation also aligns with regulatory requirements and industry standards, which emphasize ongoing vigilance in equipment safety assessments.
