Full title and description

STB DIN EN 12573-2: Welded static non‑pressurised thermoplastic tanks — Part 2: Calculation of vertical cylindrical tanks. This document gives calculation rules and dimensional guidance for welded, stationary, non‑pressurised, vertical cylindrical flat‑bottom tanks made from common thermoplastics (for example PE, PP, PVC, PVDF), as adopted and published by national bodies (DIN adoption shown as DIN EN 12573-2:2000-12).

Abstract

This standard establishes rules for the design and structural calculation of welded, static, vertical, non‑pressurised cylindrical flat‑bottom tanks fabricated from thermoplastics. It covers cylinder dimensions and banding, base thickness, roof dimensions, nozzle and lifting‑lug provisions, and factors for short‑ and long‑term loading (hydrostatic and internal pressures). Wind and snow loads are not included and require separate assessment.

General information

• Status: Published / adopted as a national adoption (e.g., DIN EN 12573-2:2000-12).
• Publication date: 2000 (national adoption date shown as 01 December 2000 for the DIN version).
• Publisher: CEN (Comité Européen de Normalisation) — adopted/published by national bodies (example: DIN as DIN EN).
• ICS / categories: 23.020.10 (Stationary containers and tanks).

• Number of pages: Varies by national publication; the DIN PDF listing shows 12 pages for the DIN EN adoption.

Scope

Applies to welded, static, non‑pressurised, vertical cylindrical tanks with flat bottoms made from thermoplastics (notably polyethylene, polypropylene, PVC, PVDF). The standard gives the calculation methodology for cylinder wall and band design, base thickness, roof dimensions, openings/nozzles and lifting lug details, and addresses both short‑term and long‑term pressure actions including hydrostatic loading. It does not cover wind or snow loading; if those loads are relevant they must be assessed separately.

Key topics and requirements

• General principles and normative references governing thermoplastic tank design.
• Temperature effects and material property considerations for thermoplastics.
• Calculation methods for cylinder dimensions and banding (including lower band and other bands).
• Rules for base (flat bottom) thickness and detailing.
• Roof dimensions and nozzle opening design considerations.
• Requirements for lifting lugs and handling points.
• Consideration of short‑term and long‑term pressure actions and hydrostatic loads; wind/snow are excluded.

Typical use and users

Used by design engineers, tank manufacturers and fabricators, QA/inspection bodies, and consultants who design or assess welded thermoplastic storage tanks for chemical, water treatment, and industrial storage applications. National standards bodies and conformity assessment organizations use the document for national adoption and reference.

Related standards

Commonly referenced companion and related documents include EN 12573-1 (Part 1: General principles) and EN 1778 (Characteristic values for welded thermoplastic constructions — determination of allowable stresses and moduli). Other tank and pressure‑equipment standards or national regulations may be relevant depending on application.

FAQ

Q: What is this standard?

A: EN 12573‑2 (adopted as DIN EN 12573‑2:2000‑12 in Germany and as national adoptions elsewhere) is the European standard that sets calculation and design rules for welded, static, non‑pressurised vertical cylindrical thermoplastic tanks.

Q: What does it cover?

A: It covers design calculation rules for cylinder wall/bands, base thickness, roof dimensions, nozzles and lifting lugs, and material/temperature considerations for common thermoplastics. It addresses hydrostatic and pressure considerations but excludes wind and snow loading.

Q: Who typically uses it?

A: Mechanical and civil engineers, tank manufacturers and fabricators, conformity assessment and inspection bodies, and consultants working on storage tanks for industry and water/chemical applications. National standards bodies use it for adoption and reference.

Q: Is it current or superseded?

A: The original EN edition is dated 2000 and was adopted nationally (for example DIN EN 12573‑2:2000‑12). Some national bodies show confirmations or later adoptions; always check the current status with your national standards body for the latest confirmation, withdrawal or replacement.

Q: Is it part of a series?

A: Yes — it is Part 2 of the EN 12573 series. Part 1 (EN 12573‑1) covers general principles; Part 2 gives calculation rules for vertical cylindrical tanks.

Q: What are the key keywords?

A: Welded thermoplastic tanks; non‑pressurised; vertical cylindrical; calculation; PE; PP; PVC; PVDF; flat‑bottom; base thickness; nozzles; lifting lugs.
