DVS 2205-1 2020-01 PDF

Full title and description

STB DVS 2205-1 2020-01 — Calculation of tanks and apparatus made of thermoplastics — Characteristic values. This item is offered in commercial catalogs as an STB-labelled (national/adopted) copy of the DVS guidance document DVS 2205‑1 (January 2020 edition / draft). The underlying DVS guideline defines characteristic material and design values for thermoplastic tanks and apparatus used in stationary installation and industrial piping contexts.

Abstract

The document provides instructions for processors and designers of semi-finished thermoplastic products to determine characteristic values (mechanical and design-related) used as the basis for calculations of tanks, apparatus, ventilation units and industrial pipelines. It focuses primarily on predominantly static loads and supplies material group‑specific characteristic data and reduction coefficients; the guidance is intended to be used together with applicable DVS guidelines and relevant DIN/EN/ISO standards.

General information

• Status: Market listings show an STB-labelled copy for 2020-01; the original DVS 2020-01 issue was published as an Entwurf (draft) and was later replaced by subsequent DVS 2205‑1 releases (Dec 2021 and 2023 editions).
• Publication date: 2020-01 (January 2020 — draft/issue).
• Publisher: Original publisher: DVS / DVS‑VERLAG (German Welding Society / DVS rule set). The STB entry appears in reseller/catalog listings as an adopted copy.
• ICS / categories: 23.020.10 (Stationary containers and tanks); related ICS for plastics/materials may also apply.
• Edition / version: 2020-01 (STB listing of the DVS 2205‑1 January 2020 issue / draft); note that DVS 2205‑1 has later revisions (Dec 2021 and May 2023).
• Number of pages: 14 pages (2020-01 issue as listed in technical-catalog records).

Scope

The guideline establishes characteristic values and calculation bases for tanks and apparatus made from thermoplastics (for example PE, PP, PVC, PVDF and other common thermoplastic groups). It is intended to support the structural and strength calculations for stationary containers, apparatus and industrial pipeline components under predominantly static loading; where relevant, the document addresses external loads such as wind, snow and seismic actions and refers users to the applicable legal/regulatory responsibilities and to other DVS/DIN/EN/ISO rules for dimensions, fabrication and testing.

Key topics and requirements

• Characteristic mechanical property values for thermoplastic material groups (baseline values and recommended design coefficients).
• Reduction coefficients and guidance for media/environmental influence on material properties.
• Application notes for tanks, rectangular and circular vessels, and flange connections (cross‑references to other parts of the DVS 2205 series).
• Assumptions and limits: predominantly static loading scenarios; applicability statements for installations in buildings and outdoors (including wind/snow/seismic considerations).
• Instructions to use these characteristic values together with the specific DVS design rules and applicable DIN/EN/ISO standards for full design, fabrication and testing compliance.

Typical use and users

Engineers and designers of chemical/process industry equipment, fabricators and assemblers of thermoplastic tanks and vessels, quality and compliance staff, consultants preparing strength and stability calculations, and specification writers who need standardised material and design characteristic values for thermoplastic constructions. The guidance is used during the design, calculation and verification stages and as a reference for material selection and reduction-factor application.

Related standards

FAQ

Q: What is this standard?

A: It is an STB‑listed item corresponding to the DVS guideline DVS 2205‑1 (Calculation of tanks and apparatus made of thermoplastics — Characteristic values). The listing appears to reproduce or distribute the DVS 2205‑1 content issued in January 2020 (catalogued as 2020‑01).

Q: What does it cover?

A: It covers how to determine characteristic mechanical and design values for common thermoplastic material groups and explains reduction factors and application limits for use in structural/calculation work for tanks, apparatus and industrial pipeline components under mainly static loads. It is intended to be used alongside other DVS and DIN/EN/ISO standards for full design and testing procedures.

Q: Who typically uses it?

A: Design engineers, tank and vessel fabricators, process industry specifiers, testing and inspection teams, and regulatory/quality professionals who require standardised characteristic values for thermoplastic constructions.

Q: Is it current or superseded?

A: The January 2020 issue was published as an Entwurf (draft) and records show it was superseded by later DVS 2205‑1 releases (December 2021 and a May 2023 edition). Catalog listings for "STB DVS 2205‑1 2020‑01" exist, but users should prefer the latest DVS 2205‑1 edition (2021/2023) for current design practice. Verify which edition is required by project/regulatory authorities before use.

Q: Is it part of a series?

A: Yes — DVS 2205 is a multipart guidance series covering calculation rules, flange connections, rectangular tanks and material‑group supplements (Beiblätter). DVS 2205‑1 is the part addressing characteristic values and is referenced by other parts in the series.

Q: What are the key keywords?

A: Thermoplastics, tanks, apparatus, characteristic values, DVS 2205‑1, calculation, polyethylene (PE), polypropylene (PP), PVC, PVDF, reduction coefficients.
