About TN Industrial Co., Ltd. (TNI)
TN Industrial (TNI) is an engineering and fabrication contractor based in Vietnam. We deliver integrated solutions from 3D/2D plant design, tank and pressure vessel design and piping stress analysis to the fabrication of stainless steel equipment and skid packages for industrial plants.
What we do
Engineering design
Basic design, FEED and 3D modeling, detail and shop drawings, isometrics and material take-off (MTO) extracted directly from the model.
Tank & pressure vessel design
API 650 storage tanks, ASME Section VIII Div. 1 pressure vessels, hygienic tanks and FRP/PVC/PE tanks, calculated in PV Elite.
Stress analysis
Piping stress analysis in CAESAR II: support loads, nozzle loads, vibration and fatigue checks.
Skid & equipment fabrication
Stainless steel tanks, static mixers, filter housings, resin traps, venturi ejectors; pump, dosing and sampling skids.
Industries served
TNI supports petrochemical, chemical, water and wastewater treatment (UF, RO), pharmaceutical, food & beverage, energy and semiconductor facilities. Many of our projects are delivered for Japanese clients, FDI manufacturers and overseas sites in Australia, New Zealand and Japan.

How we work
- Enquiry – P&ID, datasheets, existing layout and project specifications.
- Scope clarification – technical discussion, proposed solution and quotation.
- Design – 3D model, calculations and drawings for approval; clash check in Navisworks.
- Fabrication & quality control – to approved drawings and the inspection and test plan (ITP).
- Handover – equipment, quality dossier and as-built drawings.
Why TNI
- One contact from design to fabrication: drawings prepared by engineers who know the shop floor, reducing gaps between design and build.
- Accurate MTO from the 3D model: fewer surplus or missing materials and better control of procurement cost.
- Design for fabrication: plate thickness, fitting standards and weld details selected for practical, cost-effective manufacturing.
- Clear documentation: calculation reports, drawings, material and inspection records ready for client or third-party review.
