Looking for direction or recommendations on how to pressure test a 3/4 inch Aluminum schedule 80 pipe with out getting hydraulic oil in a possible leak... making the repair that much harder. Pressure will be limited by over pressure releaf at 1500 psi
The application is rear pto pump feeding front fel snow blower. Pto pump is rated at 2000 psi /20 gal per min. Have had it previous mounted on two tractors using hoses and do not like the messiness of 3/4 hoses for lack of a better term. All tractors have cabs.
So I purchased weldable 3/4 NPT ends to weld on the schedule 80 pipe. The plan was to TIG but the ends heated faster than the pipe and I ended up MIGging them. So the plan is to mount along side cab , tucked close , and have quick connects to be able to leave on year round.
Thought if I had just one small leak at high pressure, I could use that as return line.
For testing , I could individually bobble test with air pressure up to 150 or fill with water and push with a dive tank or welding gas pressure but lots of fittings issues.
Looking for suggestions. This pic shows approx position and end fittings
