Quality Assurance Plan

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 incomeing 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 froming forging and heat treatment, process control system outlines inprocess checks and controls to be followed during heat treatment and testing. Forging and interim heat treatments 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, supplimentary test like radiography, ultrasonic, corrosion testing etc., is done as per releavant standards.

MACHINING & DIMENSIONAL CONTROL : Suitable fixtures and templates are used to maintain dimensional accuracy - Necessary guages and callipers are calibrated periodically to maintain their accuracy.

FINISHING PAINTING & MARKING : Carbon and Alloy steel fitting are shot blasted or picled 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 er quality plans.

CERTIFICATION AND SUPPLIMENTARY TEST : Fitting supplied to the QAP are supplied with test certificate. Test certificate incorporated, Chemicals, Mechanical and hardness properties. Also it gives details of Heat treatment, Hydro test pressure, supplimentary test and stamping details.

Additional information and test data is furnished as per customer requirement.
