Engineering Reality Check: Temperature Kills Pressure Ratings!

We often see projects where engineers specify a massive flange (like Class 600) but fail to check the Maximum Allowable Working Pressure (MAWP)​ at the actualoperating temperature.

As the temperature climbs, the metal’s strength drops—dramatically.

⚠️ Always design for the worst-case scenario.​ A “standard” rating at room temperature is often dangerously misleading.
