BS 13766:2010 pdf download – Thermoplastic multi- layer (non-vulcanized) hoses and hose assemblies for the transfer of liquid petroleum gas and liquefied natural gas — Specification
1 Scope
This European Standard specifies requirements for two types of thermoplastic mult-layer (non-vulcanized) transferhoses and hose assemblies for carrying liquefied petroleum gas and liquefied natural gas. Each type is subdividedinto two classes, one for onshore duties, and the other for offshore.
This European Standard is applicable for hose sizes from 25 mm to 250 mm, working pressures from 10,5 bar to25 bar and operating temperatures from – 196 C to + 45 c.
NOTE Offshore LNG hose assemblies are also specified in EN 1474-2.
WARNING— Persons using this European Standard should be familiar with normal laboratory practice.
This standard does not purport to address all the safety problems, if any, associated with its use. lt is theresponsibility of the user to establish appropriate health and safety practices and to ensure compliancewith any national regulatory conditions.
