Pipeline Industry
Here is a vessel used in the pipeline industry that was hydro tested here at Extreme. Based on the size of the unit, we had to leave it on the car trailer to do the testing. Held about 390 gallon of water and was about 9 feet long. Did a 1250 psig test for 15 minutes on this unit.
Check Valve
20” Check Valve Hydro tested at 1300 psig for 30 minutes.
20 Inch Valve
20” Valve Hydro tested at 1300 psig for 4 hours.
Section VIII Steam Valve
Extreme Force Valve repaired this Spence Fig. 41-FPM for a St. Louis area hospital. The valve is a 4″ x 6″ Section VIII Steam Valve set at 30 psig. The valve required a complete VR repair. The disc and nozzle seating surfaces were both eroded from seat leakage. Fortunately, there was enough material left on both the disc and nozzle to rework them within OEM specifications. Being able to machine the parts instead of replacing them saved our customer some serious money. The valve was reset and operates like a new one. The cost of repairing this valve was about 20% of the cost of purchasing a new one!
