QUALITY ASSURANCE
The main basis of long life and durability is not only the technology, which goes into the product but also the quality assureancesystem. Which is incorporated in the manufacture of the product. A detailed QAP has thus been established on the lines required under ISO 9000 system for the manufacture of these products. CNC equipment is used to machine all critical dimensions. Detailed inspection procedures and acceptance standards have been laid down for raw materials, intermediate process and the final testing. The welding process meets all the requirements of section IX of the boiler and pressure vessel code of ASME - II. All the welded joints undergo radiography tests. This ensures that all the joints are leak free and highest class of service over long period.
