Key Engineering Highlights

  • Located in Ahmedabad with rapid logistics access to GIDC industrial estates across Gujarat.
  • Comprehensive capabilities in both Mild Steel (heavy structural) and Stainless Steel (cleanroom & chemical grade).
  • In-house certified welders, plate rolling, dish spinning, machining, and hydro-testing infrastructure.
  • Turnkey delivery from conceptual design and GA drafting through fabrication, testing, and on-site erection support.

Industrial Fabrication Expertise in Gujarat’s Chemical Capital

Gujarat is the powerhouse of India’s chemical, petrochemical, and pharmaceutical industries. At the center of this industrial ecosystem is Vishwakarma Engineering, operating from Ahmedabad and catering to clients across Vatva GIDC, Naroda GIDC, Changodar, Sanand, Ankleshwar, Panoli, Dahej, and Vapi.

We provide specialized fabrication of SS & MS reactors, pressure vessels, storage tanks, and heavy process equipment tailored to exact process flow diagrams and plant layouts.

Our Core Heavy Engineering Infrastructure

Our modern manufacturing facility is equipped with heavy machinery to handle challenging fabrication jobs:

  • Heavy CNC Plate Bending: Multi-roller hydraulic bending machines capable of rolling up to 30mm thick steel plates.
  • Automatic Welding Booms & Positioners: Motorized rotator rollers and SAW welding columns for uniform longitudinal and circular seam welding.
  • In-House Dish End Dishing & Flanging: Hydraulic presses producing precision torispherical and ellipsoidal heads.
  • Machine Shop & Tooling: Heavy lathe machines, radial drills, and boring machines for precision nozzle flange facing and agitator shaft fabrication.

End-to-End Project Execution

From receiving the client’s process datasheet to final dispatch, every equipment follows a disciplined timeline:

  1. Engineering mechanical design calculation (ASME Section VIII / IS 2825) & GA drawing approval.
  2. Material procurement with original Mill Test Certificates (MTC).
  3. Cutting, rolling, weld edge preparation, and fit-up inspection.
  4. Automated welding with qualified WPS/PQR.
  5. 100% NDT (Radiography, Ultrasonic, DPT) and Hydrostatic Pressure Testing.
  6. Surface blasting, pickling/passivation, and custom painting.
  7. Final inspection dossier compilation and safe transport logistics.
