Full title and description

DIN EN 12573-4:2000-12 — Welded static non‑pressurised thermoplastic tanks — Part 4: Design and calculation of flanged joints. (German title: "Geschweißte ortsfeste drucklose Behälter (Tanks) aus Thermoplasten - Teil 4: Konstruktion und Berechnung von Flanschverbindungen".).

Abstract

This part of EN 12573 gives principles, formulae and practical rules for the design and calculation of circular flanged joints used on welded, static, non‑pressurised thermoplastic tanks. It covers typical thermoplastic materials used for tanks (examples: PE, PP, PVC, PVDF) and provides guidance to ensure mechanical integrity and leak‑tightness of flange connections under expected loads and temperatures.

Scope

Specifies requirements for the design and calculation of circular flanged joints used on welded, static, non‑pressurised thermoplastic tanks. The part is intended for flanges and bolted connections made from or assembled to thermoplastic tank components and addresses material behaviour (typical thermoplastics: PE, PP, PVC, PVDF), temperature effects and mechanical loading relevant to above‑ground, non‑pressurised tank applications.

Key topics and requirements

• Design principles and calculation methods for circular flanged joints on thermoplastic tanks.
• Material considerations and temperature effects for common thermoplastics (PE, PP, PVC, PVDF).
• Dimensional guidance for flange faces, bolt patterns and gasket seating.
• Stress and deformation checks for flange rings, bolts/studs and mating components.
• Recommendations for achieving and verifying leak‑tightness under service conditions.
• Practical rules suitable for manufacturers and designers of welded thermoplastic tanks.

Typical use and users

Used by tank designers and manufacturers of welded thermoplastic tanks, mechanical and structural engineers involved in storage tank design, plant engineers specifying tank connections, quality and testing laboratories, and standards/approval bodies assessing flange joint designs for non‑pressurised thermoplastic storage tanks.

Related standards

EN 12573 is a multi‑part series covering welded static non‑pressurised thermoplastic tanks (other parts include general principles and calculation of vertical cylindrical tanks). National/adopted versions (e.g., DIN EN 12573 parts) and later tank‑related CEN standards (for other tank types or revised subject matter) are relevant for cross‑reference; users should check the current status of related parts and successor documents in their national catalogue.

FAQ

Q: What is this standard?

A: DIN EN 12573‑4:2000 is the German version of EN 12573‑4 (published December 2000) that provides design and calculation rules for circular flanged joints on welded, static, non‑pressurised thermoplastic tanks.

Q: What does it cover?

A: It covers calculation methods, dimensional guidance and practical design rules for flanged connections on thermoplastic tanks, including material and temperature considerations for common thermoplastics (PE, PP, PVC, PVDF).

Q: Who typically uses it?

A: Tank manufacturers, structural and mechanical designers, plant engineers, testing/inspection bodies and certification authorities involved with welded thermoplastic tank systems.

Q: Is it current or superseded?

A: Catalogue listings for the DIN edition show the document as the published 2000 edition; however, tank‑related standards and parts are periodically reviewed and other CEN standards cover related tank types. Users should verify the latest national status (confirm with DIN or the national standards body) before using the standard as the sole design authority.

Q: Is it part of a series?

A: Yes — EN 12573 is a multi‑part European standard series for welded static non‑pressurised thermoplastic tanks; Part 4 is the flanged‑joints part and other parts address general principles and specific tank geometries and calculations.

Q: What are the key keywords?

A: Thermoplastic tanks, welded tanks, flanged joints, flange calculation, PE, PP, PVC, PVDF, non‑pressurised storage tanks.
