Description / Abstract:
1. Scope
1.1 The procedures and guidelines detailed in this SAE Information
Report provide various techniques and processes to properly clean fluid
power piping prior to assembly and operation.
1.1.1 There are two recommended processes, pickling and flushing. Each
procedure will remove particulate contaminates if properly applied.
1.2 Field of Application
1.2.1 The process of conductor cleaning is applicable to hydraulic,
lubrication, and pneumatic fluid power systems.
1.2.2 The conductor fabrication process of welding, brazing, heating,
machining, and washing of tubing and pipes, causes contaminates to
collect on the inside diameter of the conductor.
1.2.3 If these contaminants are not properly removed and anticorrosive
measures taken, permanent conductor damage may result.
1.2.4 Conductor cleaning and inspection must be done prior to system
installation and assembly to remove any contaminants.
1.2.5 Proper conductor cleaning after assembly also assures that the
system contamination level meets or exceeds acceptable operating
parameters prior to system start up.
1.2.6 Hydraulic and lubrication systems require a cleanliness level
which should meet cleanliness levels established by ANSI/(NFPA/JIC)
T2.24.1.
1.2.7 This document should parallel O.E.M. and manufacturer procedures
and standards to remove conductor associated contaminants prior to
equipment assembly.
