In the oil and gas industry, having reliable valves in pipelines is critical to prevent leaks and reduce maintenance. One of the best valve solutions for this is the fully welded ball valve. In this guide, we'll explain what a fully welded ball valve is, highlight its features, and discuss its advantages and uses. We’ll also explore why they are popular with fully welded ball valve manufacturers and suppliers.
What is a Fully Welded Ball Valve?
Fully welded ball valves have a completely welded body, which means they don't require bolts or gaskets for fastening. This welded design reduces the chances of leaks and makes the valve stronger and more durable. Ideal for high-pressure systems and applications requiring a long-lasting solution.
In their construction and how they operate，these valves come in two main types: trunnion-mounted and floating ball designs. Both types can have either soft seats for low-temperature applications or metal seats for high-temperature and high-pressure uses. Cameron T31 ball valve design, is well-known for their fully welded ball valves, which meet international standards like API 6D and ISO 14313.
While based on their design and application features, main types of fully welded ball valves : Cylinder Type, Gas Direct Buried, T Series Extended Rod , PE Series Direct Buried, G Series Ball Type, etc.
Key Features of Fully Welded Ball Valves
- Welded Body Design: No external bolts or flanges, which eliminates potential leak paths.
- Trunnion or Floating Ball: Designed as either trunnion-mounted or floating, depending on the application and pressure requirements.
- Soft and Metal Seats: Different seating options to suit various environments. Soft seats provide better sealing in lower temperature, while metal seats are suitable for high-temperature and abrasive environments.
- Fire Safe: Meets strict fire safety standards, making it safe for hazardous environments.
- Long Service Life: Robust design and durable materials extend the valve's lifespan and reduce the need for repairs
- Leak Prevention: With fewer joints and no gaskets, there's less risk of leaks and fugitive emissions.
Specifications of Fully Welded Ball Valves
- Material: Made from carbon steel, stainless steel, or specialized alloys.
- Seat Options: Available with soft seats for lower temperatures or metal seats for higher temperatures and pressures.
- Pressure: Can handle exceeding 2500 psi high pressure.
- Size: Available in sizes ranging from 2 inches to over 48 inches.
- Standards: Complies with API 6D and ISO 14313 standards.
- Leak Class: Soft seats provide Class VI leakage, while metal seats have stricter leakage controls.
Advantages of Fully Welded Ball Valves
- Fewer Leak Points: The fully welded design means there are no bolts or flanges, so fewer places for leaks to occur.
- Lower Maintenance Costs: Without external fasteners, the valve is more durable and requires less upkeep, which lowers maintenance expenses.
- Improved Safety: Designed to be fire safe and withstand extreme conditions, ensuring these valves safe operation
- Longer Life: With fewer parts that can wear out, fully welded ball valves tend to last longer than other valve types.
Common Applications of Fully Welded Ball Valves
- Oil and Gas Pipelines: Ideal for high-pressure pipelines, providing reliable and safe flow control.
- Natural Gas Distribution: Used to ensure safe transport and control of natural gas.
- Petrochemical Plants: Well-suited for environments handling hazardous chemicals and gases.
- Water Systems: Their resistance to corrosion makes them a good fit for water distribution and wastewater management.
- Power Plants: Used for controlling steam, gas, and other fluids under high pressure.
