Quality Assurance plans are prepared in accordance with specific requirement stated by the customer and respective specification.
Inspection stages and check hold points are decided to carry out in process inspection and record important stages of inspection and tests.
A Separate quality Assurance / Control Department functions under the control of management independent of production. The Quality Assurance Department oversees all important quality function and performs the following activities :

MATERIAL CONTROL :

This controls the quality of all incoming material. The incoming material specification are co-related with Raw Material test certificates of the material. (both physical & chemical) The check and tests are documented. The material is given internal control No. and same is recorded for future reference.

PROCESS CONTROL :

During forming forging and heat treatment, process control system outlines inprocess checks and controls to be followed during heat treatment and testing. Forging and interim heat treatment in the process control reduce the changes of introduction of variables in the process. Each lot of fittings as defined in respective Specification are subjects to heat treatment and testing. Testing is performed in accordance with specification requirements. Test data is evaluated by QA department and recorded in appropriate format, supplementary test like radiography, ultrasonic, corrosion testing etc., is done as per relevant standards.

MACHINING & DIMENSIONAL CONTROL :

Suitable fixtures and templates are used to maintain dimensional accuracy - Necessary gauges and calipers are calibrated periodically to maintain their accuracy.

FINISHING PAINTING & MARKING :

Carbon and Alloy steel fitting are shot blasted or pickled and painted. Stainless steel fitting are pickled and passivated. All fitting are marked with size schedule, specification and manufacture stamp. Equipment celebration and audits are done as per quality plans.

CERTIFICATION AND SUPPLIMENTARY TEST :
