Full title and description

ASME SBS-2023 — Structures for Bulk Solids. A 2023 ASME consensus standard that establishes requirements for the design, fabrication, inspection, testing and materials for vertical stationary containers (silos, hoppers, tanks) used to store and process bulk solid materials under specified pressure and temperature limits.

Abstract

This standard provides technical requirements for vertical, stationary containers intended for bulk solids, covering limits on internal gauge and external pressures, thermal conditions, structural design principles, materials selection, fabrication and welding practices, nondestructive examination (NDE), testing, overpressure protection and attachments. It is intended to ensure safe, reliable storage and handling of bulk solid materials in industrial facilities.

Scope

This Standard covers requirements for vertical stationary containers used for the storage and processing of bulk solid materials at internal gauge pressures not exceeding 15 psig (100 kPa) and external pressures, including wind pressure, not exceeding 1 psig (6.9 kPa), at temperatures up to 212°F (100°C). It includes provisions for product-containing covers, first sealing surfaces for proprietary fittings, overpressure protection (venting/pressure relief), and limits the Standard’s applicability where piping or equipment connects beyond the first sealing/connection surface.

Key topics and requirements

• Design principles for vertical containers (silos, hoppers, bins) storing bulk solids, including load cases and pressure conditions.
• Material selection and allowable properties for container components.
• Fabrication and welding requirements specific to bulk-solid containers.
• Nondestructive examination (NDE) and acceptance criteria, plus testing and inspection requirements.
• Requirements for openings, covers, manholes and the first sealing surfaces of proprietary fittings.
• Overpressure protection provisions (free air venting and pressure relief devices) to meet safety requirements.
• Attachments, connections and where standard applicability terminates at specific joints or sealing faces.
• Documentation, marking and owner–manufacturer agreement points for items outside the Standard’s scope.

Typical use and users

Used by mechanical, structural and process engineers, fabricators, inspection and quality personnel, facility owners/operators and regulatory/compliance teams involved in the design, construction, commissioning and maintenance of silos, hoppers and other vertical storage/processing containers for bulk solids across industries such as agriculture, mining, cement, chemicals, food processing and power generation.

Related standards

Commonly used alongside other storage and pressure-equipment standards (examples include industry standards for welded tanks and pressure equipment, inspection and NDE standards, and site-specific codes). Typical complementary references include API standards for welded tanks and storage, ASME pressure/boiler codes where pressure-retaining parts overlap, and applicable local building and safety codes.

FAQ

Q: What is this standard?

A: ASME SBS-2023 is the ASME consensus standard titled "Structures for Bulk Solids" (2023 edition) that sets requirements for vertical stationary containers used to store and process bulk solid materials.

Q: What does it cover?

A: It covers structural design, material and fabrication requirements, welding, inspection and testing, NDE, provisions for openings and fittings, and overpressure protection for vertical containers operating within specified pressure and temperature limits (internal gauge pressure ≤15 psig, external pressures including wind ≤1 psig, temperatures up to 212°F / 100°C).

Q: Who typically uses it?

A: Mechanical, structural and process engineers, fabricators and welders, owners/operators of bulk solids facilities, inspection and QA/QC personnel, and authorities having jurisdiction who need a uniform technical baseline for safe container design and construction.

Q: Is it current or superseded?

A: The 2023 edition is the current ASME edition and has been placed on stabilized maintenance (it remains in effect; ASME will consider change requests through its maintenance process).

Q: Is it part of a series?

A: It is a stand-alone ASME standard focused on bulk-solid container structures; it is often used in conjunction with other ASME and industry standards that address pressure equipment, tank fabrication, inspection and relevant regional building/safety codes.
