5 Things to Consider Before Ordering a Tank

Apache is a custom manufacturer of tanks and vessels. Due to our customized offering, we want to provide the exact vessel you need; and that might lead to many questions and back and forth responses.  If you don't have a specification list, here are 5 recommendations for you to determine when ordering a tank.

1. Determine pressures and temperatures.  The design criteria, pressures and temperature requirements will impact material grades, thicknesses, compatibility of fittings and components, and elastomer selection.  The following items may help to determine pressures and temperatures.

  • Minimum temperature
  • Maximum allowable temperature
  • Maximum allowable pressure
  • Hydrostatic test pressure
  • Design Vacuum
  • Corrosion Allowance
     

2. Determine type of certification required.  It is advantageous to  identify the types of certification and documentation (turn-over packets) that will be required for planning purposes.  The following are common requested certificates.

 

  • As-built drawings
  • ASME data report
  • Weld traveler (Tracks material identification numbers and welders)
  • Material certificates or material test reports (MTR's, Material Test Reports to certify the chemistry of the materials)
  • Weld procedure (WPS)
  • Weld procedure qualification (PQR)
  • Weld map
  • Electropolish certificate (ASTM B912)
  • Pickle passivation cert (ASTM A380)
  • Surface finish certificates
  • Hydrostatic test certificates
  • Drainability certification
  • Sprayball test certificate
  • Tank checklist
  • Radiography certificates
  • Copy of name plate
     
3. Provide Dimensions:  In addition to the diameter and size requirements of the vessel, we also want to discover portable height and production floor restrictions.
 
4. List Finishes:  Determine the compliance requirement for finishing both inside and outside of the vessel.
 
5. Indicate use of vessel:  Even a general knowledge of the use of the vessel will help to determine design and compliance criteria.
