The short version

  1. 1The standards that govern silo, bin & hopper designSilo, Bin & Hopper Design is governed by ASME Sec VIII Div 1/2, EN 13445, PD 5500, API 650, TEMA, API 660.
  2. 2How code compliance is demonstratedCompliance is shown through documentation, not assertion. Your package should include:
  3. 3Common compliance mistakesThe most frequent compliance failures we see in silo, bin & hopper design are edition drift (working to a superseded code edition), mixing code systems mid-package, and missing project-specific overlays.
  4. 4Working across multiple jurisdictionsGlobal projects often need one package that satisfies several jurisdictions.
  5. 5The bottom lineName the edition, not just the code family — ASME Sec VIII Div 1/2 compliance is demonstrated through a documented design basis, calculations and a checker's sign-off.

Quick answer

In short, silo, bin & hopper design means engineering silos, bins and hoppers for bulk solids storage and discharge. The work is governed by ASME Sec VIII Div 1/2 and EN 13445, executed on licensed PV-Elite and checked against a documented QA checklist before issue.

The standards that govern silo, bin & hopper design

Silo, Bin & Hopper Design is governed by ASME Sec VIII Div 1/2, EN 13445, PD 5500, API 650, TEMA, API 660. Which one leads depends on the project location and the owner's specification — a US refinery package and a European commercial building may need the same discipline executed to entirely different rules.

Beyond the headline code, most projects layer client specifications on top: operator standards (Shell DEPs, Saudi Aramco SAES, ADNOC), fabricator preferences and local authority requirements. A good silo, bin & hopper design partner maps all of them into a compliance matrix at kick-off.

How code compliance is demonstrated

Compliance is shown through documentation, not assertion. Your package should include:

  • Design basis / basis-of-design note referencing the governing code and edition.
  • Calculation reports with load combinations and acceptance criteria.
  • Drawings flagged with the applicable code and material grades.
  • A documented checker's review with sign-off.
  • Revision-controlled transmittals so the latest code-compliant issue is unambiguous.

Common compliance mistakes

The most frequent compliance failures we see in silo, bin & hopper design are edition drift (working to a superseded code edition), mixing code systems mid-package, and missing project-specific overlays. Each is avoidable with a kick-off compliance matrix and a senior review gate.

Working across multiple jurisdictions

Global projects often need one package that satisfies several jurisdictions. We deliver silo, bin & hopper design to ASME Sec VIII Div 1/2 and EN 13445 routinely and maintain checklists for each, so multi-code packages are reviewed against every governing standard, not just the primary one.

Code by code

The standards behind a silo, bin & hopper design package

Each standard below governs a different slice of the scope. A compliant package names the edition of every one that applies and carries the evidence in the transmittal.

Multi-jurisdiction projects need the package reviewed against every governing standard — not only the primary one named in the contract.

  1. ASME Sec VIII Div 1/2Global

    Governs pressure vessel design by rule (Div 1) or by analysis with higher allowable stresses (Div 2).

    Evidence: a design report stating the division used, MAWP, MDMT and the nozzle load envelope.

  2. EN 13445Europe & UK

    Governs unfired pressure vessels placed on the market under the Pressure Equipment Directive.

    Evidence: a design dossier referencing the PED category, fluid group and conformity route.

  3. PD 5500United Kingdom

    Governs unfired fusion-welded pressure vessels under the UK specification.

    Evidence: calculations naming the construction category and the inspection regime it implies.

  4. API 650Global

    Governs welded above-ground storage tanks — shell courses, roof, annular plate and seismic design.

    Evidence: shell thickness calculations by the one-foot or variable-design-point method plus a seismic check.

  5. TEMAGlobal

    Governs mechanical standards for shell-and-tube exchangers — class R, C or B tolerances and details.

    Evidence: a TEMA-class statement on the datasheet with matching tube layout and baffle details.

  6. API 660Global

    Governs shell-and-tube heat exchangers for refinery and petrochemical service.

    Evidence: a datasheet and mechanical design report covering the purchaser's supplementary requirements.

About this guide

How we know this

Written from delivered work
The guidance here comes from live silo, bin & hopper design packages produced on licensed PV-Elite, Codeware COMPRESS, Autodesk Inventor — not from a content brief.
Checked against the governing codes
Every technical statement is cross-read against ASME Sec VIII Div 1/2, EN 13445, PD 5500, API 650, TEMA, API 660 and the operator specifications our teams work to daily.
Reviewed through the same checker gate
A senior engineer who signs off silo, bin & hopper design deliverables reviewed this article, using the independent-check process every client package passes through.
Revised when the standards move
Articles are re-read and re-stamped whenever a governing code edition, software release or client specification changes materially.
