Full title and description

STB DVS 2205-3 1975-11 — presentation/translation record of the original DVS 2205-3 (1975) technical guideline: "Calculation / Design of tanks and apparatus made of thermoplastics — Welded joints" (German: Berechnung von Behältern und Apparaten aus Thermoplasten — Schweißverbindungen). The record appears in some reseller/catalog listings under the label "STB DVS 2205-3 1975-11" (translation/packaging variant); the authoritative original DVS publication date is 1975 (see notes below).

Abstract

This technical guideline sets out design and construction principles for welded joints in tanks, apparatus and pipelines made from thermoplastic materials. It supplements other DVS/DIN rules for thermoplastic pressure and non-pressure vessels, provides recommended joint designs, dimensional guidance and examples intended to support—but not replace—calculation-based design. The document is a short practical rule (approx. 10 pages) aimed at designers and fabricators working with welded thermoplastic assemblies.

General information

• Status: Withdrawn / archived (document withdrawn from active sale in later revision cycles; maintained in archives and national catalogs).
• Publication date: 1975 (authoritative sources list April 1975 as the original issue; some reseller entries show a 1975-11 packaging/variant).
• Publisher: DVS‑VERLAG (DVS — Verlag für Schweißen und Verwandte Verfahren).
• ICS / categories: Plastics / rubber products and related mechanical engineering (typical ICS grouping for thermoplastics tanks and fabrication rules).
• Edition / version: Original DVS guideline 1975 edition (historic technical rule).
• Number of pages: Approximately 10 pages (short technical guideline).

Scope

The guideline covers the design and construction of welded joints for tanks, apparatus and pipelines constructed from thermoplastic materials. It gives recommended welding principles, typical joint geometries, and example dimensions intended to supplement full structural calculations; it is explicitly not a substitute for project-specific design calculations or for requirements given in other applicable standards. The guidance focuses on welded connections (not flanged or mechanical joints, which are covered in other parts of the DVS 2205 series).

Key topics and requirements

• Recommended welded-joint geometries for thermoplastic tanks and apparatus.
• Basic design principles for strength and leak-tightness of thermoplastic welds under service loading.
• Dimensional guidance and examples to complement calculation procedures (wall thickness, reinforcement, attachment details).
• Notes on limitations: examples are illustrative and do not replace project-specific engineering calculations.
• Cross-references to other parts of the DVS 2205 series for flanged joints, panels and tank types.

Typical use and users

Used by mechanical designers, process engineers, fabricators and inspection/quality personnel who design or build non-metallic (thermoplastic) tanks, vessels and associated piping. Typical applications include chemical storage tanks, process vessels and transfer piping where corrosion-resistant thermoplastics are selected. Because the guideline is historic/archived, users consult it for legacy designs, historical reference, or when working from older documentation that cites DVS 2205-3.

Related standards

Part of the broader DVS/DIN rule set for thermoplastic tanks and apparatus (DVS 2205 series). Related items include DVS 2205-1 (characteristic values/calculation fundamentals), DVS 2205-4 (flanged joints and details), and other DVS/DIN technical rules on non‑destructive testing and construction of thermoplastic equipment. Note that DVS documents have been updated in later years; some parts have newer editions or draft successors.

FAQ

Q: What is this standard?

A: A DVS technical guideline from 1975 (DVS 2205-3) that gives recommendations and example details for welded joints in tanks and apparatus made of thermoplastic materials; cataloged in some reseller lists under the label "STB DVS 2205-3 1975-11" for translation/packaging variants.

Q: What does it cover?

A: It covers recommended welded‑joint geometries, illustrative dimensional guidance and construction notes for thermoplastic tanks, apparatus and pipelines—intended as a supplement to computational design methods rather than as a standalone design code.

Q: Who typically uses it?

A: Designers, engineers and fabricators working with thermoplastic storage and process equipment, as well as inspectors referencing legacy documentation that cites DVS guidance. Because the guideline is archived/withdrawn, it is mainly used for historical reference or by organizations maintaining older installations.

Q: Is it current or superseded?

A: The 1975 guideline is withdrawn/archived in modern DVS catalogs and several distributors note withdrawal or replacement activity; users should check for newer DVS/DIN rules or later editions in the DVS 2205 family before applying the 1975 text to new designs.

Q: Is it part of a series?

A: Yes — it is part of the DVS 2205 series dealing with calculation and construction of tanks and apparatus made of thermoplastics (other parts address characteristic values, flanged joints, specific tank types and testing).

Q: What are the key keywords?

A: thermoplastics, welded joints, tanks, apparatus, DVS 2205-3, plastic welding, tank design.
