Procurement Stage
Stagewise inspection of tubes/forgings at the Tube/Forger’s manufacturing place is carried out, with witness of physical test and hand picking of tube/forging samples for chemical composition analysis by TPI at approved laboratory.

Check-Analysis and Destructive testing of the Raw Material is carried out at Government approved Laboratories in presence of third party inspector/client's inspector (if desired).
In Process Stage
After approval of the forgings/plates/tubes duly identified vis a vis the Heat Marks, they are processed for machining/fabrication and drilling operations. Various Stages are offered to TPI as per the approved QAP.

We have complete range of precision measuring instruments duly calibrated to enable third party inspector/client's inspector to carry our inspection such as
  • Calibrated Micrometers (Range upto 300 m.m.)
  • Calibrated Vernier Calipers (Range upto 1000 m.m)
  • Inside Dial Calipers for measuring Grooves & Bores (Range 10-35 m.m)
  • Dial Bore Gauge (Range 10 to 150 m.m.) and many more gauges.
  • Pole D Apparatus for measuring the Hardness of the Material.
  • Ultrasonic Thickness Measuring Instrument.
  • Machining Surface Comparator.

Stagewise & Final Inspection is carried out on every components by our internal inspection engineer, (not associated with the production). All the equipment & components are thoroughly checked and rechecked & recorded before being offered to the third party inspector/client's inspector.

Necessary QAP/WPS etc are in place and welding carried out using calibrated welding rectifiers. Calibrated Ovens for preheating of electrodes are used.
Post Weld Stage
After carrying out the welding, visual check and Dye Penetrate check is carried out by us. Radiography is carried out by competent agencies hired by us.

For Non-Destructive testing such as Ultrasonic testing/Radiography of Weld Joints/Hardness survey/Magnetic Particle Test, competent agencies are hired to carry out the job in presence of third party inspector/client's inspector (if desired).

Cases where Post-Weld Heat Treatment is required, the material is sent to outside agency for carrying out Heat Treatment.
Final Dimensional & Visual Check
Entire Equipment is checked visually for any weld splatters, surface finishing etc. The equipment is checked dimensionally to confirm that all the dimensions within the allowable tolerances of the applicable code.
Final Hydro-test
Final Hydro-test is carried out, after all the above stages are cleared. For carrying out the hydro-test we have
  • Hydraulic Test Pumps - Pressure upto 150 Kgs/Cm2
  • Calibrated Pressure Gauges upto 150 Kgs/Cm2
Acid Cleaning/Sand Blasting/Painting is carried out after the client’s inspection wing/third party inspector has cleared the equipment.
Documentation
Heat Chart, along-with material test certificates, Release Note & Internal Inspection Report along-with the Hydro-test and Guarantee Certificate are prepared for the every equipment. Soft Copies of the above are also available.

External Inspection Agencies.

The jobs executed by us can be under Stagewise or Final Inspection by our client or by Inspection Agency appointed by them.

It may be noted that apart from client's own inspection wing, we have carried out jobs under inspection at different stages by following agencies at our shop or at our client’s premises.
