Fabrication capabilities
What we do in-house, how quality is controlled and what documents you get with every job.
How a fabrication job runs
Drawing and QAP review
We check your GA drawings, QAP and specification, and raise queries before material is ordered.
Material and cutting
Plate is checked against mill certificates, then cut with heat numbers transferred to each part.
Rolling, fit-up and welding
Parts are rolled, fitted and welded to qualified procedures by qualified welders.
Testing and dispatch
NDT, any PWHT and dimensional checks are completed, then the job ships with its dossier.
Welding, NDT and documents
Welding
Procedures and welders qualified to ASME Section IX. WPS and PQR submitted for approval with the QAP.
NDT
- Radiography and ultrasonic testing
- Dye penetrant and magnetic particle testing
- Extent as per your QAP and design code
Heat treatment
Post-weld heat treatment where the code or specification requires it, with recorded charts.
Dossier
Material certificates, weld maps, NDT reports, dimensional reports and test records, compiled per item.

| Titanium and nickel alloys | ASTM B265 titanium; B443, B424, B575 nickel-alloy plate (guide) |
Complete with flanges and bolting
Flanges and bolting for every fabrication come from Teshi Fittings and Teshi Fasteners, so you do not need separate vendors for the loose items.
Questions buyers ask
Do you fabricate to client drawings?
Yes. Almost all heavy fabrication is made to the client's GA and detail drawings and QAP. We prepare shop drawings for approval where the contract requires them.
Which welding codes do you follow?
Welding procedures and welders are qualified to ASME Section IX, and fabrication follows the code named in your specification, such as ASME B31.3, ASME Section VIII or IS 2825.
What testing is done on fabrications?
Dimensional inspection plus the NDT your QAP calls for: radiography, ultrasonic, dye penetrant or magnetic particle testing, and hydrotest where applicable. PWHT is done when the code or specification requires it.
Can you supply the flanges and bolting for the fabrication?
Yes. Flanges come from Teshi Fittings and bolting from Teshi Fasteners, so nozzles and ducts arrive complete.
