You deal with the people who make it. No trader margin, no lost information between you and the shop floor.
Traceable to the heat
Every piece is marked and linked to its mill certificate. EN 10204 3.1 as standard, 3.2 when witnessed.
Every grade on one order
Carbon steel, alloy, stainless, duplex, nickel alloys and titanium, so a mixed BOQ goes to one supplier.
Inspection your way
Your QAP, your third-party agency, PMI and NDT as specified. Since 1971, ISO 9001:2015 certified and IBR approved.
Send your GA drawing for a fabrication quote
We review drawings, QAP and quantities and reply with price and schedule.
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.

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.
