1.Material Production Monitoring
All raw materials are manufactured under strict ladle analysis supervision at certified foundries.
2.Incoming Material Verification
Upon arrival at our facility, all materials undergo precise compositional analysis using advanced spectroanalysis equipment.
-
Key quality controls:
Real-time molten metal monitoring during casting
Full chemical composition verification
Traceability maintained throughout production chain
Compliance with ASTM material specifications
Cryogenic Treatment System (-196°C)
A standard conditioning process essential for LNG service valves and comparable cryogenic applications.
Film thickness inspection on each layer guarantees the good protection on the valves, a good paint provides longer service life of the valves.
Our 1200°C electric furnace facilitates multiple heat treatment cycles.
Hydraulic leakage test
All mechanical properties test will act before we use the materials to secure the performance and safety.
