692 Coupling pressure testing and hose testing with prt

Product catalog summary

Introduction
The document outlines the specifications and procedures for a Coupling & Hose Pressure Testing Unit designed for aircraft refueling systems. It ensures compliance with pressure limits to prevent system failures.

Specifications
Aircraft systems must not exceed a refueling pressure of 50 psi and a shock pressure of 120 psi. Hose end pressure control valves (HEPCV) and in-line pressure control valves (ILPCV) are used to maintain these limits. Routine hydrostatic pressure testing is recommended for hoses where fuel pressure may exceed 5.5 bar.

Recommended Testing Pressures

20 bar for commissioning and after coupling attachment.
15 bar for routine testing of fueller delivery hoses and hydrant servicer hoses.
10 bar for hoses less than 2” in diameter.

Components of the Testing Unit

3” L port selection valve.
2 x FC107 couplings with dust caps.
1 x 2” nipple with blanking cap.
1 x 3” wafer style butterfly valve with ratchet lever.
1 x 3” ball valve.
Calibrated pressure gauge (0 – 20 bar) with trace pointer.
Capped ½” stainless steel ball valve for pressure relief.
Spare ¼” BSP socket for diagnostics.
“A” frame removable legs with fork lifting points.
Stainless steel product recovery tank (PRT) / hose pressure testing reservoir.
PRT low-point drain with cam lock protection.
Hydraulic hand pump for hose pressure testing.
Assorted fittings for various hose end sizes.

Conclusion
The Coupling & Hose Pressure Testing Unit is essential for maintaining the integrity of aircraft refueling systems by ensuring pressure limits are adhered to through regular testing.

CUSTOMER: Greystar SPECIFICATION NO: 692 SUBJECT: Coupling & Hose Pressure Testing Unit Coupling / Hose Pressure Testing Unit Aircraft systems are designed to withstand a maximum refuelling pressure of 50 psi and a maximum shock pressure of 120 psi. To ensure these limits are not exceeded hose end pressure control valves (HEPCV) are used as a primary controller and in-line pressure control valves (ILPCV) are used as secondary controllers. All refuelling vehicles pressure control system should be tested to a scheduled procedure. Routine hydrostatic pressure testing of hoses is recommended were...
