  • Valves are 1.5 times pressure rating tested with water.
  • Maximum hydrostatic test to 20000 psi
  • Nitrogen test to 3000 psi maximum
  • Tube fitting burst test to 20,000 psi maximum
  • Heat no. traceability available
pic 1 On-site inspection and measurement are thoroughly conducted.   pic 2 Hydrostatic test with water to 1.5 times maximum working pressure prior to shipment.
pic 3 Vision measurement to control dimensional accuracy.   pic 4 Leakage can be detected by reading the graph.
pic 5 Multi-function CNC measuring equipment to measure taper, parallel, roundness and concentricity.   pic 6 Nitrogen generator & testing bench for gas tight test.
pic 7 Measuring roughness of surface to assure a perfect seal in service.   pic 8 Life cycle test to ensure consistent quality.
