Is phosphating necessary for tubes which have continuous oil flow
(-----) February 8, 2008
I work for an organisation which manufactures Dumpers. We use lot of steel tubes for the flow of hyd oil - medium to high pressures and at elevated temperatures say 70 - 80 deg C. Since there is a continuous flow of oil in the pipes, I would like to know if Phosphating of the inside of the tubes can be eliminated so some savings both in time as well as money can result.

Well yes you could save a few bucks in the near term. If you don't mind the few random pieces that rust a little on the inside. It is hard to control everything. You might not realize what a little rust inside a hydraulic system can do. Your customers will find out though.
