Raw Material Control
The steel materials are selected from well-known domestic manufacturers as the suppliers: Shougang, Handan Iron and Steel, Tangshan Iron and Steel, and Wuhan Iron and Steel (to ensure chemical composition and mechanical properties).
Welding & Inspection
Welding is submerged arc welding, and each weld is inspected by a flaw detector (ultrasonic flaw detection). After passing the test, it will continue to the next process.
Runtest before Shipping
After each equipment is completed, it will be installed and run-test in the factory to ensure stable operation of the equipment before it is loaded and shipped.
Gears and shafts are made of forged 45#, 40 chrome, 42 chrome molybdenum, and quenched and tempered.
