System Cleanliness Part 3
Copyright REDOX 2002
SAE J 1227 Section 5.1 states the system and its components must be as clean as the most
demanding component in the system. Using REDOX pipe that meets these cleanliness demands plus
scale resistant welding gives you the opportunity to save tremendous upfront costs associated with
flushing. Flushing times with REDOXpipe is measured in minutes not days or weeks.

There was 1000' of 3" SCH XXS REDOX built into seven different spools. Each of these spools
were subjected to cutting, bending, welding and other fabrication processes. The overall contaminant
level after fabrication remained low do to good handling practices and the use of REDOX pipe
which meets SAE J 1227 Section 5.1. Total cumulative time necessary to flush all spools was
89 minutes. Please note that the highlighted starting ISO number on the tapes below. Even
though ISO numbers are after all fabrication operations are complete, they are still 1000
times cleaner than the average pickled pipe before fabrication.
