Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Type-57P size range | 50-315mm (2"-12") | Asahi/America — Advanced PE Industrial Piping Systems (Chem Proline / Chem Prolok / Poly-Flo) |
| Chem Proline system pressure rating | 150 psi @ 68°F | Asahi/America — Advanced PE Industrial Piping Systems (Chem Proline / Chem Prolok / Poly-Flo) |
| Stress-crack resistance (FNCT, ISO 16770) | 14,648-hour average test result vs the 8,760-hour (1-year) Advanced PE minimum standard | Asahi/America — Advanced PE Industrial Piping Systems (Chem Proline / Chem Prolok / Poly-Flo) |
| Real field installation | City of Vallejo, CA water treatment plant (2013) — Chem Proline/Chem Prolok system replaced leaking CPVC sodium hypochlorite (bleach) piping | Asahi/America — Advanced PE Industrial Piping Systems (Chem Proline / Chem Prolok / Poly-Flo) |
Asahi's own installed-project list is dominated by plants that had leaking PVC or CPVC piping before switching — at least 9 of 26 documented installations explicitly replaced failed PVC/CPVC, the same failure mode a wrong-material choice creates on a new water-treatment butterfly valve line.
Every one of these municipal case studies is a plant that already tried PVC or CPVC and watched it fail in service — the Type-57P earns its spot on a water treatment plant BOM by outliving the material it's usually asked to replace, not by being cheaper on day one.
