| Applies when | hydrogen peroxide, h2o2 |
|---|---|
| Avoid | flanged or coupling connections where welded is feasible (undefined) |
| Recommend instead | Peabody Engineering () |
| Rationale | Hydrogen peroxide up to 50% concentration, 1.9 specific gravity. Peabody's guidance specifically prefers welded PE fittings over flanged/coupling connections - fewer gasket interfaces reduces catalytic-decomposition initiation points, since H2O2 decomposes into oxygen and water and off-gassing is a real design driver requiring special venting, not incidental to standard tank ventilation. |
