Overhauling Valve In Vungtau

Overhauling Valve

A valve is a device that is designed to regulate the flow of gases, liquids, fluidized solids, or slurries by controlling the opening, closing, or obstruction of various passageways. Although valves are technically considered as pipe fittings, they are often categorized separately. When a valve is open, the fluid flows from high pressure to low pressure.

Valves have various applications in different fields, such as industrial, government, military, petroleum, commercial, marine, and transportation. They can be operated manually using a hand wheel, lever, or pedal, or they can be automatic and driven by changes in pressure, temperature, or flow. Safety valves fitted to hot water systems or boilers are examples of automatic valves that respond to changes in pressure.

More complex control systems that require automatic valve control based on an external input, such as regulating flow through a pipe to a changing set point, require an actuator. The actuator will stroke the valve based on its input and setup, allowing for accurate positioning and control over a wide range of requirements.

When conducting an overhaul, the scope of work typically includes a range of activities. Some examples of the scope of work involved in an overhaul might include:

1. Visual inspection of all external and internal surfaces for corrosion and damage. This includes the valve body, internal components, and any associated piping.
2. Undertaking a pressure test to determine whether the valve is lifting and operating correctly. This is important to ensure that the valve is performing its intended function and can handle the required pressure.
3. Stripping down the valve and taking measurements of the “as found setting” to identify any deviations from the expected performance. This helps to identify any wear or damage that may be affecting the valve’s operation.
4. Refurbishing internal parts to ensure that the valve operates correctly. This may include cleaning, re-machining, and reconditioning components as needed.
5. Replacing any damaged or suspect parts. This may include worn or damaged seals, springs, or other components that are critical to the valve’s operation.
6. Minimal lapping to return sealing faces and plugs to true. This involves machining or grinding the sealing surfaces to ensure that they form a tight seal.
7. Rebuilding the valve to appropriate standards, using new packing and gaskets as required. This ensures that the valve meets the required specifications and can perform its intended function.
8. Conducting pressure, bubble, and seat leakage tests to ensure that the valve operates correctly and meets the required standards for pressure, flow, and leakage.

Valves are an essential component in many industrial processes, providing safe and efficient operation and protection in emergencies. It is crucial that they operate flawlessly each time they are required. A worn, faulty, or leaking valve could result in a far greater cost than that of replacing it with a new one.

Regular valve overhauls and repairs can offer several benefits, including:

1. Economic repair of 90% of valves that are typically considered non-repairable or sent to the graveyard. This can save a considerable amount of money in replacement costs.
2. Cost savings of over 60% compared to the cost of purchasing new valves.
3. Reconditioned valves can help eliminate or significantly reduce the need for costly modifications to the existing pipe work.
4. Delivery times are often much shorter for reconditioned valves, typically within days rather than weeks.
5. Plant shutdowns and maintenance can be completed more efficiently and cost-effectively by utilizing reconditioned valves.

In summary, regular valve overhauls and repairs can save time and money, provide a safer operating environment, and extend the life of valuable equipment. It is essential to have a reliable and experienced valve repair service provider to ensure proper maintenance and repair of these critical components.
