BEPeterson supplied a custom turnkey hydrostatic testing system to SAIC who is a prime contractor to the United States Navy. BEP engineering team worked extensively with SAIC and subcontractors technical staffs from initial concept and all the way through on-site installation and commissioning.

The test chamber skid with the loading / unloading skid is roughly 6’ W x 30’ OAL while the attached water supply skid is roughly 8’ x 8’.

Test vessel Operating Pressure: 2500 PSIG at 100°F MAWP: 3000 PSIG     MDMT: 32°F

The test chamber shall has an extendable rail system with provisions to load and secure the units under test. The system was fully integrated with operator friendly controls and all electrical and electro-pneumatic controls were mounted in an IP64/NEMA 4 enclosure and met the requirements of NFPA 70 (NEC)

A Factory Acceptance Test (FAT) was performed at BEPeterson’s facility prior to acceptance and shipment.  BEPeterson was responsible for field installation and training at the jobsite.
