VPACII™ Valve Inspection Leak Detection and Quantification

About 5-10% of valves in oil and gas plants leak. Of those, about 1% of valves are responsible for 70% of total losses. Knowing which valves are costing you and creating safety hazards can reduce annual losses by millions of dollars.

Valve leaks that go undetected can have lasting consequences for asset integrity and production capacity within your entire facility. Small leaks that are left undetected can expand into larger leaks over time, which can be damaging to surrounding equipment. When dealing with hazardous or volatile materials, valve leaking presents a huge environmental risk, moving plants away from regulatory compliance and industry standards.

Effective inspection techniques allow you to identify and quantify valve leaks before more serious damage can occur. Developed in conjunction with worldwide oil & gas industry leaders, MISTRAS’ VPAC II™ valve through-valve leak detection system not only identifies the presence of through-valve leaks but also uses a proprietary algorithm to quantify leak rates to help you prioritize inspection and maintenance strategies.

MISTRAS’ VPAC II™ provides leak detection for valves in a wide range of facilities, including:

• Offshore Platforms
• Pipelines
• Process Plants
• Refineries

In-Service Through-Valve Leak Detection & Quantification with VPAC II™

Through-valve leaks that go unnoticed can accumulate into huge losses, which limit overall output and productivity. Early leak detection allows repairs to take place as soon as leaks are identified, which limits the hazard and economic cost of wasted resources.

With non-destructive testing (NDT) inspection systems like the VPAC II™, this solution effectively detects through-valve leakage while assets remain in service and limits the need for costly facility downtime.

MISTRAS’ VPAC II™ effectively estimates the amount of gas or liquid (liquid to liquid or liquid flashing to gas) leaking through a nominally closed valve, which results in a loss in dollars and cents. These results enable plant operators to quickly respond when a valve sticks or leaks, saving the losses that accumulate when leaks got unnoticed.

Benefits of Valve Leak Quantification

MISTRAS’ valve leak inspection solutions provide products and software to help facility operators determine if leaks are occurring, where they are located, and how fast materials are leaking. Leak quantification provides essential information for repair and maintenance prioritization, while MISTRAS software can record information for future tracking and trending.

Our solutions for through-valve leak inspection, detection, and quantifying provide a variety of additional benefits, including:

• Reduced gas and liquid losses
• Reduced plant shutdown time
• Better plant integrity and safety
• Efficient repair and maintenance
• Helps plants move toward zero emissions
