02

Pan-India Crews — Erect · Pipe · Maintain

Site Execution & Services

Certified field crews for process & utility piping, heavy fabrication, equipment erection, insulation, protective coatings and rapid shutdown turnarounds — executed under a zero-accident permit culture.

  • ASME B31.3 / IBR piping with TIG & orbital welding
  • Rigging, erection & laser alignment of machinery
  • Hot/cold insulation, blasting & SA 2.5 coatings
  • 24/7 maintenance & turnaround mobilization

03Services Matrix

Certified crews for every site discipline

Six field-service lines mobilized from Ankleshwar to plants across India — each executed under permit-to-work discipline with documented QA at every work front.

Complete piping distribution networks for steam (IBR), chilled water, compressed air, nitrogen, raw solvent transfer, and product discharge lines. Fully compliant with ASME B31.3 standards with 100% radiographic or hydrotest QA.

  • P&ID line routing & isometric drawing generation
  • ASME Section IX qualified welders (TIG/SMAW)
  • High-pressure hydrostatic testing up to 1.5x design pressure
  • Sanitary hygienic orbital welding for pharma/food applications

In-house plate cutting, CNC shearing, pyramid plate rolling, fit-up, and welding of mild steel, stainless steel, and specialty alloy assemblies. We fabricate process skids, reactor jackets, hopper cones, and custom heavy structural steel.

  • Multi-tier equipment access platforms & mezzanine floors
  • Structural columns, pipe racks, and bridge gantries
  • Custom skid bases with vibration damping isolators
  • Comprehensive weld inspection, DPT (Dye Penetrant), and ultrasonic tests

Safe erection of reactors, storage tanks, tall distillation columns, centrifuge units, ball mills, heavy silos, and rotary equipment. Rigorously planned with certified cranes, custom lifting tackle, and zero-incident rigging plans.

  • Engineered lift plans & rigging safety risk assessments
  • Anchor bolt grouting and vibration isolation mounting
  • Dial indicator & precision optical/laser shaft alignment
  • Torque-verified flange bolting & mechanical completion certificates

Minimizes process thermal losses, protects operators from burn hazards, and prevents condensation on chilled lines. Finished with precision-formed aluminum or stainless steel sheet metal cladding with weather-sealed joints.

  • High-density Rockwool mattresses for high-temperature steam lines
  • Preformed PUF / Nitrile foam insulation for chilled water and brine lines
  • CNC-swaged aluminum & SS304 weather-tight cladding jackets
  • Removable insulated thermal jackets for valves, flanges, and pump casings

Guards heavy steel structures, storage tanks, and process vessels against corrosive industrial atmospheres, chemical fumes, and weather degradation. Executed using high-pressure abrasive blasting and airless spray systems.

  • Abrasive grit / copper slag blasting to Swedish Standard SA 2.5
  • High-build epoxy zinc phosphate primers for corrosion resistance
  • Aliphatic polyurethane topcoats for UV resistance and gloss retention
  • Dry film thickness (DFT) gauge audits & holiday spark testing

We specialize in high-pressure plant shutdowns where every hour of downtime counts. Our Ankleshwar-based rapid deployment teams mobilize certified welders, fitters, riggers, and safety supervisors to execute planned revamps safely.

  • 24/7 dedicated round-the-clock shift execution
  • Brownfield hot/cold tie-in spools and valve replacements
  • Internal vessel cleaning, agitator seal replacements, and nozzle repairs
  • Formal pre-startup safety review (PSSR) and leak testing handover
