PIP VESBI002

This Practice provides requirements for the construction of cylindrical atmospheric and low-pressure, welded, shop- and field-fabricated dry bulk solids containers (e.g., bins, hoppers, silos, and gravity blenders).

This Practice describes requirements for design, materials, fabrication, examination, testing, and shipping for cylindrical shell, single-wall containers for dry bulk solids (i.e., bins, hoppers, silos, and gravity blenders) having internal design pressures not exceeding 15 psig (103 kPa) and/or full vacuum external pressure at the top of the container in its normal operating position. Containers may be welded, shop- and field-fabricated, and shall generally be designed in accordance with the philosophy and requirements of the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, henceforth referred to as the Code. Code inspections and stamping are not required for these containers.
