Rubber hose assemblies for oil suction and discharge services - Specification for the assemblies
This document specifies the characteristics of four types of oil suction and discharge hose assemblies used for the conveyance of petroleum, including crude oils and other liquid petroleum products containing a maximum aromatics content of 50 % (v/v). It is not suitable for liquefied petroleum gas and natural gas.
Hose assemblies to this document can be used in the temperature range -20 °C to 82 °C.
The hoses specified are in the size range of nominal bore 50 to 500 and may be smooth bore, rough bore or armoured rough bore.
NOTE Hoses for use with petroleum products having an aromatic content greater than 50 % (v/v) are outside the scope of this document but the requirements may be used as a basis for such hoses on request to the manufacturer.
Gummischlauchleitungen für das Ansaugen und Fördern von Öl - Anforderungen an die Schlauchleitungen
Diese Europäische Norm legt die Anforderungen an vier Typen von Schlauchleitungen zum Ansaugen und Fördern von Öl fest. Diese werden zum Transport von Erdöl einschließlich Rohöl und anderen flüssigen Erdölerzeugnissen mit einem maximalen Volumenanteil an Aromaten von 50 % verwendet. Sie sind nicht einsetzbar für verflüssigtes Gas und Erdgas.
Schlauchleitungen entsprechend dieser Europäischen Norm können in einem Temperatur-bereich von -20 °C bis +82 °C eingesetzt werden.
Die festgelegten Schläuche sind in einem Größenbereich vom Nenndurchmesser 50 bis 500 und können eine glatte, eine raue oder eine verstärkte raue Innenschicht haben.
ANMERKUNG Schläuche zur Verwendung mit Erdölerzeugnissen, die einen Volumenanteil an Aromaten von mehr als 50 % haben, liegen außerhalb des Geltungsbereichs dieser Europäischen Norm. Die Anforderungen können aber als Grundlage für solche Schläuche bei Anfragen an den Hersteller verwendet werden.

Les flexibles faisant l'objet de la présente norme ne conviennent pas pour le gaz de pétrole liquéfié et le gaz naturel.
Les flexibles concernés par la présente Norme européenne peuvent être utilisés à des températures comprises entre - 20 °C et 82 °C.
La dimension du diamètre nominal des flexibles spécifiés est comprise entre 50 et 500. Le revêtement peut être lisse, rugueux ou rugueux armé.
NOTE Les tuyaux utilisés pour les produits pétroliers ayant une teneur en aromatique supérieure à 50 % (v/v) n'entrent pas dans le domaine d'application de la présente Norme européenne. Cependant, sur demande auprès du fabricant, les exigences de la présente norme peuvent servir de base pour ces tuyaux.

3.1 Electrically bonded hose assembly hose assembly that uses a metallic wire connection to create a low-resistance electrical connection between the end connections 3.2 Electrically discontinuous hose assembly hose assembly that incorporates an electrical insulation between the end of the helical wire or/and wire cord reinforcement and on or both couplings 4 Classification 4.1 General WARNING — Careful consideration needs to be given before the use of electrically discontinuous hoses for transferring liquids known to generate static charges. In no circumstances should more than one length of electrically discontinuous hose be used in an individual transfer pipeline and effective electrical continuity to earth from both ends of the electrically discontinuous hose should be maintained. 4.2 End – use Hose assemblies for this application are classified according to end-use as follows: - Type R, rough bore hose assemblies for dock operation and intended for situations where a relatively stiff, heavy and robust assembly can be used. The lining of the rubberized fabric is supported and reinforced by an internal (hot-dipped) zinc coated steel wire helix. Type R assemblies are electrically continuous; - Type A, armoured rough bore hose assemblies for dock operation. In addition to an internal zinc coated steel wire helix there shall be external helical armour of a similar material. Type A hoses are electrically continuous and may be lighter and more flexible than type R; - Type S, smooth bore hose assemblies for dock operation where flexibility and lightness are important. Type S hose assemblies may be electrically continuous or electrically discontinuous (see Warning); - Type L, hose assemblies for dock service where greater flexibility, lower weight and ease of handling are of primary consideration. Type L hose assemblies may be electrically continuous or electrically discontinuous. They are only suitable for discharge applications (see Warning). 4.3 Pressure ratings and designations Each type of hose assembly shall be designated according to the type letters R, A, S, or L followed by the maximum working pressure given in Table 1. For the purposes of this document the maximum working pressure includes an allowance for surge pressures above the normal operating pressure. SIST EN 1765:2005
