21、 1765:2004 (E) 4 Introduction This document specifies minimum requirements for the satisfactory performance of wire or textile reinforced rubber hose assemblies of both smooth and rough bore types for oil suction and discharge services. The hoses are commonly used for transferring crude oil and liqu

22、id petroleum products, other than liquefied petroleum gas and natural gas, to and from tanker and bunkering vessels or for similar duties ashore. Specific details of the construction of hoses are not rigidly defined in this document since it is felt that this could restrict the introduction of impro

23、ved methods of construction. The hose assemblies have been classified and designated in terms of service pressure, which includes an allowance for surge pressure and which equates to the factory test pressure. To keep this specification in line with other documents this factory test pressure is also

24、 defined as the maximum working pressure (see Table 1). It is the responsibility of the user to determine the appropriate working pressure, which will depend on the severity of the users operating conditions and on the service life that is expected of the hose assembly. It is necessary for the purch

25、aser to provide certain information about the hose assembly and its intended use at the time of enquiry and/or order; this information is listed in Annex A (informative). Recommendations concerning packaging and transportation are given in Annex B (informative) and expected masses of hoses, in kilog

26、rams per metre of free length, are given in Annex C (informative). Licensed Copy: Wang Bin, ISO/Exchange China Standards Information Centre, 25 January 2005, Uncontrolled Copy, (c) BSIEN 1765:2004 (E) 5 1 Scope This document specifies the characteristics of four types of oil suction and discharge ho

27、se 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

28、 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

29、used as a basis for such hoses on request to the manufacturer. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、initions For the purposes of this European Standard, the terms and definitions given in EN ISO 8330:2000 and the following apply. 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

37、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 di

38、scontinuous 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 hos

39、e 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 f

40、abric 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

41、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 discontinuou

42、s (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).

43、 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

44、the normal operating pressure.
