PREPROCESSING

Once approval drawings are returned and cut sheets are released from Engineering to the shop, preprocessing begins. This includes:

  • Shearing material to the correct size
  • Roll and brake forming
  • Head bumping
  • Seam welding
  • Head flanging and polishing
  • Fabricating half pipe and full pipe coils.
  • Fabricating 

MACHINE SHOP

During the preprocessing phase, the machine shop is busy making the various components needed for each tank, such as:

  • Fittings, flanges, ferrules
  • Base plates, manway components, lifting lugs, reinforcing pads, vents
  • Teflon bushings, bearings, scraper blades and spacers
  • Cut to length pipe and square tubing, pipe bending
  • Waterjet machining center
  • Plasma table cutting 

When preprocessing and machine shop work is complete, the materials are staged in the production bays in preparation for tank fabrication to begin.

PRODUCTION

Tank fabrication and assembly takes place in one of four production bays.  Various factors such as tank size and current shop loading will determine which bay will build each job.  Pharmaceutical and Biopharmaceutical vessels are always built in the electropolish bay.

ELECTROPOLISH BAY

Vessels that will be electropolished are built in our separate 15,000 square foot electropolish bay.  By design, this area is isolated from the rest of the plant by an exterior wall providing the cleanest possible environment for vessel fabrication.  This production bay facilitates:

  • Welding, grinding and fabrication of vessels away from potential contaminants
  • In-house passivation and electropolishing to 10 Ra; vessels up to about 80,000 liters
  • Superior quality control and improved lead times
  • Testing, inspections, FAT and full documentation services available
  • Passivation or electropolishing services of customer furnished parts

IN-HOUSE TESTING EQUIPMENT AND METHODS

  • Radiography
  • PMI, metal and alloy analysis
  • Hydro, 1000 psig maximum
  • Shop air, 125 psig
  • Vacuum box, for API designed tanks
  • Liquid penetrant, fluorescent or color contrast methods
  • Profilometer, Ra finish thickness verification
  • Ferrite testing
  • Hardness testing

MISCELLANEOUS

  • Sandblasting, done in-house
  • Galvanizing, contracted
  • Painting, contracted

Certifications

SFI utilizes various standards to ensure your product is built to the highest quality possible.

We hold the following certificates:

  • ASME “U” certification
  • National Board “R” certification

Other standards are utilized as required, such as:

  • API 620 & 650
  • ASME BPE Guidelines
  • Canadian Registration Number (CRN) documentation
  • Ministry of Manpower-Singapore (MOM) documentation
  • PED (European Pressure Equipment Directive) “CE” Mark
  • UL-142
  • USDA
