BS EN 1765:2016EN 1765:2016 (E) 5 Introduction This document specifies minimum requirement
24、s 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 liquid petroleum products, other than liquefied petroleum gas and natural gas
25、, 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 improved methods of construction. The hose assemblies have been classified and
26、 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 defined as the maximum working pressure (see Table 1). It is the respons
27、ibility 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 essential that the purchaser provides certain information about the hose assembly and its intend
28、ed 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 kilograms per metre of free length, are given in Annex C (informative). BS EN 1
29、765:2016EN 1765:2016 (E) 6 1 Scope This European Standard 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 i
30、s 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. Hoses for use with petroleum
31、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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this docume

40、ly 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
41、and one 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 u
42、sed 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
43、 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
44、 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
45、 where flexibility and lightness are important. Type S hose assemblies may be electrically continuous or electrically discontinuous (see Warning in 4.1); BS EN 1765:2016EN 1765:2016 (E) 8 Hoses and hose assemblies for this application shall be divided into two grades: Grade M: electrically bonded; G
46、rade : electrically conductive; see EN ISO 8031:2009, Annex A for new recommended marking to indicate conductive lining, conductive cover or conductive lining and cover; Type L, hose assemblies for dock service where greater flexibility, lower weight and ease of handling are of primary consideration
47、. Type L hose assemblies may be electrically continuous or electrically discontinuous. They are only suitable for discharge applications (see Warning in 4.1); Hoses and hose assemblies for this application shall be divided into two grades: Grade M: electrically bonded; Grade : electrically conductiv
48、e; see EN ISO 8031:2009, Annex A for new recommended marking to indicate conductive lining, conductive cover or conductive lining and cover. 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 workin
49、g 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.
