120ft diameter API 650 liquid storage tanks

Steel Storage Welded Tank Certification
A certificate shall be supplied for each tank. This practice is intended to simplify keeping the records of future inspection in separate files for convenience. When a group of crude oil storage tanks is being constructed on one order and in one general location some specific form of reporting other than a API 650 liquid storage tanks Manufacturer’s report may be preferred by both parties. It would seem desirable that the details on each contract be settled when the purchase order is placed; if they are not covered in the proposal, then they shall be given as information in the inquiry.
