Quality Assurance at the tube mills and draw bench is carried out through both destructive and non-destructive tests for weld integrity. Such as coneest, flattening tests and crushing tests on-line and off-line. All safety requirements are adhered to before packing and dispatch.
Other mechanical testing for tensile strength, yield strengths and hardness are conducted as part of the process sequence in line with the customer’s specifications. These include dimensional and visuals checks for thickness, outside diameter, inside diameter, ovality, fin height, surface finish and other material defects. After certification the products are dispatched. Wherever required, work test certificate is furnished. Futher inspections by third party like Lloyds, Rites, Bureau Veritas, TPL, or customer’s own inspection are provided for, if required by the customer.
