There is a lot to consider for an effective hydraulic system maintenance program. Though hydraulics can be complex systems, it is best to keep the program simple, have a plan and follow it. Remember that hydraulic fluid and systems are dependent on each other, so it’s critical to ensure procedures are put into place for both.
Today we are sharing with you the results of some recent hydrostatic burst testing performed at our Cleveland manufacturing facility. The takeaway from this test is that the Brennan fittings held strong well beyond the burst pressure of the tubing, in fact, 4 times higher than the burst pressure up to a remarkable 20,000 PSI when the tubing iteself failed (at about 1:40 in the video).
Hydraulic fluids are formulated with additives developed for the specific application. These additives are typically made by companies who specialize in petroleum based materials. Additive manufactures develop specialized additives made specifically for hydraulic oil for construction equipment. The additives consist of chemical compounds that protect the base stock of natural mineral oil-based fluids.
