| Aluminized Type 2 |
|
The aluminized type 2 (ALT2) coating develops an oxide barrier layer on the interior pipe surface and thus performs well in areas where the presence of soft water would require a coating other than galvanized CSP. In addition to performing well in soft water conditions, CSP with an ALT2 coating performs in wider ranges of pH and resistivity. When installed in the established environmental conditions, field evaluations of CSP with the ALT2 coating have proven this material will achieve a 100+ year service life. |
