Quality Control: Exceeding Standards, Pursuing Absolute Zero Leakage

Equipped with advanced instruments — every single product undergoes the most rigorous scientific validation.

Spectrometer (Material Analysis)

Ensures 100% raw material compliance. Spectral analysis technology rapidly and accurately verifies the chemical composition of metal elements.

  • Elemental accuracy to 0.01%
  • Multi-point sampling for quality verification

Helium Leak Detector (Vacuum)

For critical and high-purity applications, helium leak testing is available upon request to meet stringent sealing and quality requirements.

Utilizing highly sensitive vacuum-based helium detection technology, even extremely small molecular leaks that are difficult to detect through conventional hydrostatic testing can be effectively identified.

  • 100% per-unit inspection

High-Pressure Test Bench

Simulates real-world operating conditions through pressure and functional testing to verify valve sealing performance and structural integrity.

  • API 598 compliant
  • Pressure integrity and sealing performance verification
