Définition du produit et mission de sécurité :
The Welded Ball Valve serves as a permanent sealing fortress for high-pressure pipelines in the oil, gas, and chemical industries, completely eliminating leak points through a fully welded, integrated connection. This welded ball valve achieves zero leakage throughout its lifespan in harsh operating conditions ranging from Class 600 to 2500 ultra-high pressure and -196℃ to 200℃, meeting API 6D/ASME B31.3 standards. Its spherical single-weld structure offers inherent advantages such as uniform stress distribution, light weight, and high strength, combined with a double-piston effect seat, ensuring a 30-year service life.
Technologie de soudage à la bille JH Gene
- Automated penetration process: single-sided welding with double-sided forming (100% pass rate for RT/UT inspection, Level I).
- Zero-stress deformation structure: Finite element analysis optimization of weld joints (residual stress ≤30MPa)
- Intrinsically safe sealing: Double protection with metal bellows and fireproof secondary seal.
- Analyse technique du produit
- Soudage bout à bout (BW)
- Soudure à emboîtement (SW)
- Système d'actionneur
- Technologie de forgeage/moulage
The superior performance of the JH Welded Ball Valve stems from a complete welding technology system: the automated penetration process combines GTAW and FCAW processes to achieve single-sided welding with double-sided forming; the zero-stress structure optimizes the weld bevel using finite element analysis, controlling residual stress below 30MPa; the intrinsically safe seal integrates a metal bellows and a fire-resistant graphite ring, providing double protection; and the intelligent traceability system assigns a QR code identity to each weld, fully recording 20 process parameters. This system ensures that the welded ball valve maintains a permanent seal under various harsh operating conditions.

FAQ-Vanne à bille soudée
Welded Ball Valves form permanent connections with pipelines through welding, widely used in demanding applications in oil, natural gas, and chemical industries. They are particularly suitable for pipeline systems requiring zero leakage, high pressure, and corrosion resistance, as well as critical applications like long-distance transmission pipelines, power plants, and refining installations where maximum safety and sealing performance are essential.
Butt Weld (BW) and Socket Weld (SW) are two different welding connection methods:
Butt Weld Connections: Valve ends aligned and welded to pipe ends, creating high-strength, full-bore connections suitable for high-pressure, high-temperature, and large-diameter pipeline systems
Socket Weld Connections: Pipes inserted into valve socket ends for welding, offering easier and faster installation, suitable for small diameters and space-constrained applications
