Full title and description

STB DVS 2205-2 E 2019-09 — Calculation of tanks and apparatus made of thermoplastics: Vertical round, non‑pressurised tanks (English-language adoption of the DVS 2205-2 series). The document provides calculation rules, dimensional requirements and design guidance for factory-fabricated vertical cylindrical thermoplastic tanks and associated collecting devices (tray collectors, flat bases, sloping bases and related beiblatt/annexes).

Primary publisher: DVS‑VERLAG (DVS – German Welding Society). STB indicates a national adoption/translation record of the original DVS document for use in certain national standards catalogs.

Abstract

This standard (DVS 2205-2, adopted as STB DVS 2205-2 E 2019-09) defines geometry, material and calculation rules for vertical, round, non‑pressurised tanks made from thermoplastics (e.g., PVC, PP, PE, PVDF). It covers structural wall and base design, minimum wall thickness, assembly/welding considerations for factory‑fabricated cylindrical tanks, and specific sub‑documents (Beiblatt/annexes) for tray collectors, sloping bases and seismic/earthquake considerations. The standard is intended to ensure safe, functional and constructible designs for storage tanks used in chemical, water and process industries.

General information

• Publication date: 2019-09 (E 2019-09 edition / draft date shown as 01 Sep 2019 in publisher records).
• Publisher: DVS‑VERLAG GmbH (Verlag für Schweißen und verwandte Verfahren).
• ICS / categories: 23.020.10 — Stationary containers and tanks (industrial tanks).
• Edition / version: E 2019-09 (English-language adoption of DVS 2205-2; several Beiblatt/annex parts exist and later revisions were issued in 2021 and beyond).
• Number of pages: Varies by part and publisher release — typical part lengths reported in catalogs range from about 16 pages (some beiblatt parts) up to ~42 pages for fuller editions/compilations.

Scope

The document specifies structural calculation procedures, dimensional requirements and minimum material characteristics for vertical round, non‑pressurised thermoplastic tanks and associated collecting/tray devices. Included topics cover: cylindrical shell and base geometry; recommended minimum wall thickness (practical minimums used in the rules); manufacturing/joining (welded panels, wound or extruded pipe construction); restrictions on openings for certain collector types; and special provisions found in Beiblatt (annex) documents for flat bases, sloping bases, tray collectors and seismic/tank‑fixing measures. The standard is targeted at factory‑fabricated tanks made from common thermoplastics (PVC, PP, PE, PVDF).

Key topics and requirements

• Calculation rules for cylindrical shell stresses and base loading for non‑pressurised vertical tanks.
• Material scope: guidance applicable to PVC, PP, PE, PVDF and similar thermoplastics.
• Manufacturing forms: welded panels, wound or extruded pipe construction and their allowable detailing.
• Minimum wall thickness recommendations (practical minimums reported in parts, e.g., 4 mm for some collector types) and dimensional limits.
• Beiblatt (annex) items covering: tray collectors, flat‑base tanks in seismic zones, sloping bases and tanks without tilt securement in earthquake areas.
• Notes on responsibilities for compliance with applicable national laws (building, water, occupational safety) in addition to the technical rules of the standard.

Typical use and users

Typical users are design and mechanical engineers, tank manufacturers and fabricators of thermoplastic storage vessels, process engineers specifying containment for chemical or water systems, inspection and certification bodies, and purchasers who require conformity to DVS technical calculation rules or national adoptions (STB entries) when procuring factory‑fabricated thermoplastic tanks.

Related standards

Related documents include other parts of the DVS 2205 series (multiple Beiblatt/annex parts addressing specific base types, seismic provisions and collector designs), national adoption records (STB listings), and complementary standards on welded plastics fabrication and tank testing. Later revisions and consolidated DVS 2205-2 releases (2021 and subsequent updates) supersede or expand some 2019 beiblatt content.

FAQ

Q: What is this standard?

A: STB DVS 2205-2 E 2019-09 is the English-language / national-adoption record of DVS 2205-2 (2019) covering calculation and design rules for vertical, round, non‑pressurised tanks made of thermoplastics. It corresponds to DVS publications and Beiblatt annexes that address specific tank and collector variants.

Q: What does it cover?

A: It covers structural calculation methods, dimensional and material guidance for factory‑fabricated cylindrical thermoplastic tanks (materials such as PVC, PP, PE, PVDF), manufacturing forms (welded panels, wound/extruded pipes), minimum thickness guidance and Beiblatt annexes for tray collectors, base types and seismic considerations.

Q: Who typically uses it?

A: Tank designers, manufacturers/fabricators of thermoplastic vessels, process and plant engineers, compliance and inspection bodies, and procurement specialists who require conformity to DVS technical rules or national‑level adoptions.

Q: Is it current or superseded?

A: The 2019-09 release is recorded in publisher catalogs as a draft/adoption and has been superseded by later revisions and updated Beiblatt releases (subsequent DVS 2205-2 editions and Beiblatt updates were published after 2019). Users should check for the most recent DVS 2205-2 edition or national adoption before relying on a 2019 copy.

Q: Is it part of a series?

A: Yes — it is part of the DVS 2205 series (calculation of tanks and apparatus made of thermoplastics) and is accompanied by multiple Beiblatt (annex) documents that address specific tank types and design situations. Several Beiblatt items were released or updated around 2019 and consolidated in later DVS releases.

Q: What are the key keywords?

A: thermoplastic tanks; DVS 2205-2; vertical round tanks; tray collectors; PVC, PP, PE, PVDF; Beiblatt; non‑pressurised tanks; tank calculation; flat base; seismic design.
