86 EUROPEAN ALUMINIUM ASSOCIATION ALUMINIUM IN COMMERCIAL VEHICLES CHAPTER VI 9. Special design issues 9.1. Tanks for the transport of dangerous goods - ADR Tanks for the transport of dangerous goods have to be built according to the rules defined in the following agreement and standards: • ADR: Agreement for the transport of Dangerous goods by Road1 • EN 13094 “Tanks for the transport of dangerous goods - Metallic tanks with a working pressure not exceeding 0.5 bar - Design and construction” • EN 14025 “Tanks for the transport of dangerous goods - Metallic pressure tanks - Design and construction” In particular, tank shell thickness (e) is determined by the following equivalence formula, where e is the minimum shell thickness 0 for mild steel and R and A, the m tensile strength and elongation of the metal chosen. e = e × 464 0 3 √(R × A) m 2 For tanks protected against damage: Furthermore, absolute minimum shell thicknesses are fixed depending on the type of tank, the shell dimension and the material used. • For shells with circular cross-section ≤ 1.80 m: e = 3 mm 0 e cannot be lower than 4,00 mm for aluminium alloys2 • For shells with circular cross-section > 1.80 m e = 4 mm 0 e cannot be lower than 5,00 mm for aluminium alloys For other tanks: e = 5 mm for shells with circular cross-section ≤ 1.80 m 0 e = 6 mm for shells with circular cross-section > 1.80 m 0 1. See ADR - Annex A – Part 6 – Chapter 6.8: http://www.unece.org/trans/danger/danger.htm 2. Whatever the result of the equivalence formula is. Aluminium road tankers (Schrader)
EUROPEAN ALUMINIUM ASSOCIATION ALUMINIUM IN COMMERCIAL VEHICLES CHAPTER VI 87 Suitable aluminium alloys for that application are listed in standard EN 14286 “Aluminium and aluminium alloys - weldable rolled products for tanks for the storage and transportation of dangerous goods”. See also Chapter V, section 6.4 in this manual. For tanks protected against damage, several alloys listed in EN 14286 allow manufacturing tank shells with e = 5.3 mm (corresponding to R x A = 6600) and m even e = 5.0 mm (for those with R x A ≥ 7152). m 9.2. Tippers 9.2.1. Construction Tipper body trailers (or “dump bodies”) are constructed in two different versions: • Combination of plates and extrusions (more frequently used version) • Extrusion intensive construction, where all sides of the trailer are made of clamped and / or welded extrusion profiles Another version which came up in the last few years is a material – mix version with a steel bottom plate and aluminium side- walls (bolted to the steel plate). Two main tipper types can be differentiated: • Rectangular trailer • Half – pipe trailer Independent from the type of tipper, all extrusion cross – sections and the thickness of the plates are calculated with respect to: Aluminium tipper bodies (Stas)
