A team of inspectors from the American Society of Mechanical Engineers (ASME) paid a visit to the Sichuan Bluestar Machinery Co, on March 12, to examine its U and U2 certificates and steel seals. This was the seventh inspection of its kind. The company first got its ASME certificate, in 1992.The recent inspection will help the company with adjusting its product mix and expanding its overseas markets. The ASME certification and U and U2 steel seals are the most itative of their kind in the world for pressure containers and are a veritable passport for Bluestar in getting its pressure containers to go global.
