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.
