Assurance plans are prepared in accordance with specific
requirements stated by the customer and respective ASTM
specifications, Mandatory and supplementary requirements
are translated to special instructions and audits performed
during manufacture and inspection.
stages and check hold points are decided to carry out
in process inspection and record important stages of inspection
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 activites
CONTROL : This controls the quality of all incoming material.
The incoming material specification are co-related with
Raw Materials test certificates of the material.
checks and tests are documented. The material is given
internal control No. and same is recorded for future reference.
CONTROL : During forming, forging and heat treatment,
process control system outlines in process checks and
controls to be followed during heat treatment and testing.
Forging and interim heat treatment in the process control
reduces the chances of introduction of variables in the
lot of Fittings as defined in ASTM specification are subjected
to Heat treatment and 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 code
& DIMENSIONAL CONTROL : Suitable fixtures and templates
are used to maintain dimensional accuracy - Necessary
gauges and calipers are calibrated periodically to maintain
their accuracy .
PAINTING & MARKING : Carbon and Alloy Steel Fitting
are shot ballasted or pickled and painted. Stainless Steel
Fitting are pickled and passivated. All Fittings are marked
with size schedule, specification and manufacturer stamp.
calibration and audits are done as per quality plans.
AND SUPPLEMENTARY TEST : Fittings supplied to the QAP
are supplied with test certificate. Test Certificate incorporated,
Chemical, Mechanical and Hardness properties. Also it
gives details of Heat treatment, Hydro pressure, Supplementary
test and stamping details.
information and test DATA is furnished as per customer
