This standard establishes rules for the design and calculation of welded static, vertical, non-pressurised, cylindrical,
flat-bottom thermoplastic tanks. This standard applies to tanks fabricated in the following thermoplastics:
Polyethylene (PE)
Polypropylene (PP)
Poly (vinyl chloride) (PVC)
Poly (vinylidene fluoride) (PVDF)
This standard does not take into account wind and/or snow loading.If wind or/and snow loading has to be taken into
account additional calculations are necessary.
This standard is applicable to tanks in which the cylindrical shell is made of welded plates or a wound cylinder or an
extruded pipe.
The calculation takes into account short-term and long-term active pressures as well as the hydrostatic loading. The
following values are long-term pressures and represent the limiting values:
Overpressure: 0,0005 N/mm2 (0,005 bar)
Low pressure: 0,0003 N/mm2 (0,003 bar)
This standard is only applicable to tanks which are not intended to withstand internal pressure or vacuum, other than
that which may occur during the transfer of fluids (including gases) in their normal operation.
Die Norm legt Regeln für die Konstruktion und Berechnung von geschweißten, ortsfesten, drucklosen, runden, stehenden Flachbodentanks aus Thermoplasten fest. Wind- und/oder Schneelasten werden nicht berücksichtigt. Der zylindrische Mantel kann aus geschweißten Platten oder einem extrusionsgewickelten Zylinder oder einem extrudierten Rohr gefertigt sein. Die Berechnung berücksichtigt sowohl Drücke über kurze oder lange Zeiträume, als auch die hydrostatische Belastung.
