Full title and description

STB DVS 2205-5 E 2020-01 — Calculation of containers and apparatus made of thermoplastics (rectangular containers). This document is the STB-designated version of the DVS guideline DVS 2205-5 (edition 2020‑01) and contains design and calculation rules for rectangular, stationary tanks and apparatus fabricated from thermoplastic materials.

Abstract

The standard sets out principles, formulae and constructive recommendations for the structural design and verification of rectangular thermoplastic tanks (examples: PE, PP, PVC, PVDF). It covers plate/plate‑theory based calculations for wall and floor panels, options for external stiffening (ribs, frames), and provisions for common loads relevant to tank engineering. The guidance is intended to produce safe, serviceable rectangular containers for chemical and storage applications.

General information

• Status: Published (STB designation of DVS 2205-5:2020-01); later editions of the DVS guideline have been released (see FAQ).
• Publication date: 2020-01 (January 2020 — edition suffix “2020-01”).
• Publisher: Original publisher DVS‑VERLAG (DVS — German Welding Society); STB indicates the national designation/adoption used for distribution.
• ICS / categories: 83.140.99 (Other rubber and plastics products / thermoplastic containers and apparatus).
• Edition / version: Edition 2020-01 (DVS 2205-5:2020-01, STB DVS 2205-5 E 2020-01).
• Number of pages: ~42 pages (published draft/standard listings record 42 pages for the 2020-01 edition).

Scope

The document gives calculation and construction rules for rectangular, cuboid tanks and apparatus intended for stationary use and made from thermoplastic materials. It addresses material types commonly used in industry (PE, PP, PVC, PVDF), typical support and stiffening options (external ribs, frames, composite or steel supports), and verification rules for hydrostatic and other relevant load cases for in‑service use. The scope is focused on engineering design rather than manufacturing process detail.

Key topics and requirements

• Design and calculation methods for rectangular thermoplastic panels and walls (plate theory / membrane approximations where applicable).
• Material considerations and typical thermoplastics covered (PE, PP, PVC, PVDF).
• Rules for external reinforcement: ribs, frames and hybrid supports (GRP or steel).
• Load cases and verification: hydrostatic pressure, and provisions for environmental loads and installation effects as applicable.
• Dimensional and constructive recommendations for floors, supports and connections relevant to long‑term serviceability.

Typical use and users

Engineers and designers of chemical storage and processing equipment, tank fabricators, plant engineers, and consultants use this guideline to size and verify rectangular thermoplastic tanks. Software vendors and calculation tool developers also implement the standard’s rules (tank‑calculation packages reference DVS 2205 parts for automated checks).

Related standards

DVS 2205 is a multi‑part rule set covering thermoplastic tanks (other parts address cylindrical tanks, welded joints, constructive details, etc.). The DVS 2205 series (parts 1–5 and supplements) should be consulted together when designing thermoplastic apparatus; national adoptions (STB, DIN or others) may be available for specific parts.

FAQ

Q: What is this standard?

A: STB DVS 2205-5 E 2020-01 is the STB‑designated edition of the DVS guideline DVS 2205-5 (edition 2020‑01) covering calculation rules for rectangular thermoplastic tanks and apparatus.

Q: What does it cover?

A: It provides calculation methods, constructive recommendations and verification rules for rectangular tanks made from thermoplastic materials (plate/wall calculations, reinforcement options, typical loads and service conditions).

Q: Who typically uses it?

A: Mechanical and chemical plant designers, tank fabricators, structural engineers, and software/tool developers who perform tank strength and serviceability calculations.

Q: Is it current or superseded?

A: The 2020-01 edition is a published edition, but DVS has issued later revisions (drafts and a 2024 revision). Users should check for the latest DVS 2205-5 release (DVS 2205-5:2024‑03 replaces earlier 2020/2023 drafts). For projects requiring the newest rules, use the most recent edition.

Q: Is it part of a series?

A: Yes — it is one part of the DVS 2205 series (design and calculation of thermoplastic tanks and apparatus). Designers typically use multiple parts of the series together (e.g., cylindrical tank rules, welded joints and constructive details).

Q: What are the key keywords?

A: Thermoplastic tanks, rectangular containers, DVS 2205-5, plate theory, ribs/frames, PE/PP/PVC/PVDF, tank calculation.
