Fabrication capabilities

Seven disciplines under one roof. VSS Enterprises designs, fabricates and installs petroleum storage tanks, pressure vessels, process tankage and piping — and takes the statutory licence through with them.

01 · Core discipline

Petroleum storage tanks

The core of the business. VSS Enterprises fabricates above-ground and underground storage tanks for high speed diesel (HSD), furnace oil (FO), light diesel oil (LDO) and solvents such as solvent 1425 — in mild steel and stainless steel, sized and detailed to the petroleum class of the product stored.

Because the Petroleum Rules classify products by flash point, the tank design, shell thickness, venting, bunding and separation distances all follow from the class. That is the engineering discipline VSS brings: a tank that is not only fabricated correctly, but designed to clear PESO inspection.

  • Class A, B and C petroleum storage tanks
  • Above-ground and underground configurations
  • MS and SS construction to drawing
  • Bunding, venting and fire-protection provisions
  • Statutory drawings for licence submission

02 · Turnkey

Turnkey fuel storage & distribution

A tank on its own is not a fuel facility. VSS Enterprises delivers the whole system on a turnkey basis: tank, containment, piping, pumps, dispensing points, instrumentation and commissioning — plus the PESO and explosive licence that makes it legal to operate.

This is what separates VSS from a plain fabrication shop. The client signs off on a working, licensed installation rather than a tank that still needs a contractor, a consultant and a licence application.

  • Tank, bund and containment construction
  • Distribution piping for HSD, FO and solvents
  • Pumps, dispensing and flow measurement
  • Fuel monitoring and auto-control systems
  • PESO licence and local NOC coordination
  • Testing, commissioning and handover

03 · Pressure equipment

Pressure vessels, air receivers & reactor columns

Fabrication of pressure vessels, air receivers, reactor columns and LPG spheres, built to drawing and code, with hydrotesting and documentation as part of the delivery.

These are the components where fabrication quality is least forgiving — a poorly welded receiver is a hazard, not an inconvenience. VSS's fabrication unit is set up for plate forming, fit-up and multi-pass welding with 400 A welding transformers.

  • Pressure vessels to drawing and code
  • Air receivers for compressed-air systems
  • Reactor columns and process vessels
  • LPG spheres and storage bullets
  • Hydrotesting and inspection records

04 · Environmental

STP, ETP & RO plant tanks

MS and SS tankage, receivers, bar screens and clarifiers for sewage treatment plants, effluent treatment plants and reverse osmosis systems.

Water and effluent treatment is one of the fastest-growing segments in Indian industry, driven by tightening pollution-control norms and zero liquid discharge requirements. Every treatment plant needs fabricated tankage and structural components — and VSS already builds them.

  • MS and SS treatment tanks
  • Bar screens and clarifier components
  • Receivers and process vessels
  • RO plant tanks and skids
  • Supporting structural steelwork

05 · Piping

MS & SS piping — process, utility & steam

Fabrication and erection of mild steel and stainless steel piping for fuel, compressed air, hydrant, utility and steam services — including compressor piping, supports and hangers.

Piping is where a fabrication job either comes together or falls apart. VSS executes it both at the fabrication unit and at site, which means the tank, the piping and the commissioning are handled by one team with one set of drawings.

  • HSD, FO and solvent distribution piping
  • Compressed-air and compressor piping
  • Steam and condensate piping
  • Hydrant and utility piping
  • Supports, hangers and structural steelwork

06 · Fabrication

Tankers, chimneys, ducting & structures

Petroleum transport tankers, water tankers, industrial chimneys, ducting and structural steel work — fabricated and erected to drawing, at the unit or on site.

Field distillation units, grills and general structural fabrication round out the capability, so clients with an unusual or one-off requirement are not turned away.

  • Petroleum and water transport tankers
  • Industrial chimneys and ducting
  • Structural steel and grill work
  • Field distillation units
  • General fabrication to client drawing

07 · Maintenance

Tank cleaning, testing & annual maintenance

Petroleum tanks need cleaning at least once every three years. Left alone, water and sludge build up and are drawn into the diesel generator when fuel is transferred from the main tank — which clogs injectors, damages the fuel system and can end in generator failure.

VSS cleans and tests tanks without stopping the plant: fuel is offloaded to a substitute tank, the master tank is cleaned and hydraulically tested for leaks, and the fuel is refilled afterwards.

  • Tank cleaning and sludge removal
  • Nitrogen purging (0.8–1 kg/cm²)
  • Hydraulic leak testing as per rule
  • Fuel offloading and refilling to avoid downtime
  • Annual maintenance contracts for fuel facilities
  • Underground pit de-watering systems

Plant & equipment

The fabrication unit

VSS Enterprises runs a fabrication unit at Subedar Palya, Jarakabande Kaval, near Yelahanka in north Bangalore. Tankage is fabricated here and shipped to site; piping, installation, licensing and structural work is executed at client locations across India.

The unit is equipped for plate forming, cutting, drilling and multi-pass welding, with experienced engineers, fitters and riggers on the team.

  • Plate bending machine — 1800 mm × 25 mm1 no.
  • Pillar drilling machine — 25 mm capacity1 no.
  • Hand drilling machine (Wolf)2 nos.
  • Bench grinders1 no.
  • Angle & straight grinders4 nos.
  • Hacksaw cutting machine — 12″ capacity2 nos.
  • Welding transformers — 400 A7 nos.
  • Gas cutting sets2 nos.
  • Erection tools — pulleys, derrick etc.1 set
  • Hand tools3 sets

Tool & tackle for erection is arranged at site as required.
