Following are the few important points covered in our Quality Control Procedure.
The castings are inspected at the foundries for the following:
1. Blow holes
2. Sand hold-up
3. Rib position
4. Heat numbers
5. Surface finishing
6. Riser cutting
7. Painting line
8. Verification of certificates, etc.
Castings are again inspected at the shop floor visually. Properties mentioned in certificates are verified with applicable standards. Procurement of casting is done from reliable foundries only.
On all the castings, heat numbers are cast/punched by the foundries. The castings are shot blasted and heat treated as per the required heat treatment procedure. Foundries provide us with the certificates for chemical and physical properties of castings from their own/independent laboratories. The test bars of each heat are available with the foundries for verification of physical and chemical properties.
As a system of quality control procedure and cross verification we check the chemical and physical properties of castings at our end of at least 10% of the quantity received by us. The material for checking chemical and physical properties is sent to a reputable laboratory of the customer’s choice.
The foundries from where we procure castings or forgings are approved by various inspection agencies such as Engineers India Limited, Lloyds, Bureau Veritas, PDIL, S.G.S., Bax Counsel, TUV, D&V, IRS, IBR, etc.
Since we accept only sound casting, we do not adopt any welding process on pressure withstanding areas. The castings are sent back to the foundries for any welding, if required, and the same is duly stress relieved after welding.
