This Practice provides requirements for the construction of cylindrical, atmospheric and low-pressure, welded, shop-fabricated or field-erected dry bulk solids 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 having internal design pressures not exceeding 103 kPa (15 psig) and/or full vacuum external pressure at the top of the container in its normal operating position. Containers may be welded, shop-fabricated or field-erected, and shall generally be designed in accordance with the philosophy and requirements of the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, although inspections and marking are not required for these containers.
