BS EN 14420-5 specifies the fitting combinations, design, materials and dimensions for hose fittings with couplings for tank trucks (TW couplings).
Couplings for tank trucks in accordance with this document are intended to link hoses with connections for the transport of liquids, solid matters and gases with the exception of liquid gas and steam. They can be employed in a working pressure range of –0,8 bar1) up to 16 bar at working temperatures of –20 °C up to +65 °C. Couplings for tank trucks for other operating conditions are subject to agreement.
BS EN 14420-5 on Hose fittings with clamp units is useful for:
TW Couplings or Tank truck couplings are asymmetric couplings to connect hoses mainly for loading and unloading tank trucks.
Using BS EN 14420-5 you can determine the mechanical characteristics of TW tank truck couplings.
The dimensions mentioned in BS EN 14420-5 is useful in designing these hoses. Specifications and requirements specified are useful in identifying the materials which are resistant to the fluids.
By using BS EN 14420-5 you can ensure the sustainability of these TW tank truck couplings in different conditions and can improve the quality of these couplings used in fitting the hoses.
