Which pipe schedule is required for all piping in a CNG system?

In a CNG (Compressed Natural Gas) system, using schedule 80 pipe is essential due to its higher pressure rating and thicker wall compared to other schedules. This is crucial because CNG systems often operate at high pressures, and the use of schedule 80 pipe provides the necessary strength and safety margin to withstand these conditions.

Schedule 80 pipes are designed to handle greater internal pressure, making them suitable for the safe transport of compressed natural gas. Their increased thickness helps prevent failures, leaks, or ruptures, which can pose significant risks in terms of safety and environmental hazards.

In contrast, pipes classified under other schedules, such as schedule 40, may not provide adequate pressure resistance for the operational demands of a CNG system. Using a pipe with insufficient pressure tolerance could lead to serious safety issues, including potential system failures and leaks, highlighting the importance of using appropriate materials that can endure the specific requirements of CNG applications.
