Trunnion Ball Valves Comply With API 6D And ASME B16.34 Standards

I. Dual-standard Compliance and Diversified Applications of Trunnion Ball Valves

TRUNNION BALL VALVESstrictly adhere to the international standards of API 6D and ASME B16.34, combining professionalism and universality. The API 6D standard is applicable to long-distance oil and gas pipelines and high-pressure process systems, ensuring safe operation under extreme working conditions. The ASME B16.34 standard is suitable for multiple industries such as the chemical and power industries, supporting various connection methods (flange, threaded, welded) and material selections (from carbon steel to high-performance alloys) to cope with different media and environments.

II. Structural Design: Balancing Safety and Efficiency

• High-pressure Bearing Capacity:TRUNNION BALL VALVESin accordance with both standards adopt a reinforced valve body structure. Under the API 6D standard, the pressure rating covers from 150LB to 2500LB, focusing on high-pressure long-distance transmission scenarios and meeting the high-pressure transmission requirements of long-distance pipelines. The ASME B16.34 standard ensures stable pressure bearing under different working conditions with the help of accurate pressure-temperature rating tables.

• Bidirectional Sealing and Fire Safety:The sphere and valve seat adopt a metal-soft seal composite design. The API 6D standard mandatorily requires a fireproof function, while the ASME B16.34 standard allows it to be configured as needed. Its bidirectional sealing characteristic can prevent fluid leakage in both directions and is suitable for complex systems with reverse flow.

• Automatic Pressure Relief Protection:The API 6D standard comes with a standard automatic cavity pressure relief device to prevent internal pressure build-up caused by temperature changes. The ASME B16.34 standard can integrate this function as required to enhance system safety.

III. Stringent Tests and Quality Assurance

• API 6D Standard:It is required to pass strict inspections such as hydrostatic tests, full-flow sealing tests, and fire simulation tests to ensure reliable operation under extreme conditions such as high pressure and fire, meeting the requirements of oil and gas pipelines that have zero tolerance for leakage.

• ASME B16.34 Standard:It requires non-destructive testing such as radiographic testing and ultrasonic testing to verify the integrity of the internal structure of the valve body. Meanwhile, it provides detailed pressure-temperature performance parameters for precise valve selection.

IV. Core Advantages: Efficient Control and Durability

TRUNNION BALL VALVESreduce the operating torque by virtue of the fixed sphere design, enabling quick opening and closing within 90°, thus improving the efficiency of fluid control. Coupled with anti-corrosion materials and precision machining processes, they can withstand the erosion of sand-containing and corrosive media for a long time and reduce the maintenance frequency. Under the framework of the API 6D and ASME B16.34 standards, they provide industrial fluid systems with solutions that combine both safety and economy.
