DIN EN 1765:2016-12EN 1765:2016 (E) 5 Introduction This document spe
30、cifies 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 liquid petroleum products, other than liquefied pet
31、roleum 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 improved methods of construction. The hose assemblie
32、s 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 defined as the maximum working pressure (see T
33、able 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 essential that the purchaser provides certain information about the ho
34、se 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 kilograms per metre of free length, are given in Anne
35、x C (informative). DIN EN 1765:2016-12EN 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 aromati
36、cs 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.
37、 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. 2 Normative references The following documents, in whole or in part, are normati

In no circumstances should more than one length of el
