PMI-MASTER Pro2 analyser helps Douson Valve control the quality of steel alloys

“PMI-MASTER Pro2 provides us good on-site reliability, high precision, and results within 20 seconds, which is very fast. That’s why when we needed to purchase further analysers, we turned to Hitachi.”

Suzhou Douson Valve Co., Ltd is a specialist manufacturer of industrial pipeline valves. Top priority for the quality department is how to best ensure quality control and assurance in the production process. They do this by analysing the composition of the nickel and iron in the steel alloys that are incoming but also ensuring consistent quality throughout the production process. 

 

STRICT QUALITY CONTROL ENSURES SUCCESS WITH CUSTOMERS

Douson Valves has implemented strict technical standards for quality control as part of their design, manufacturing and sales processes. According to Li Yun, Laboratory Director in the Quality Department, “We carry out quality control against the API 6D standard which means inspecting the chemical composition of the incoming material samples.”
