PIP VESBI002

This Practice describes the materials, design, fabrication, inspection, testing, and documentation requirements for the construction of atmospheric and low-pressure, welded, shop- and field-fabricated dry bulk solids bins, hoppers, silos, and gravity blenders for various chemical facilities. These bulk solids bins, hoppers, silos, and blenders generally meet the philosophy and requirements of Section VIII, Division 1, of the ASME Boiler and Pressure Vessel Code, henceforth referred to as the Code; however, Code inspection and stamping are not required.

This Practice designates requirements for the design and construction of welded, cylindrical shell, single-wall vessels having internal design pressures not exceeding 15 psig and/or full vacuum external pressure at the top of the vessel in its normal operating position. Data sheet PIP VEDBI003 is required to define options covered herein and other specific requirements applicable to the particular vessel under consideration for service (startup, normal operation, upset, shutdown), location, maintenance, etc.
