22、ecifies requirements for two types of thermoplastic multi-layer (non-vulcanized) transfer hoses and hose assemblies for carrying liquefied petroleum gas and liquefied natural gas. Each type is subdivided into two classes, one for onshore duties, and the other for offshore. It specifies sizes from 25
23、 mm to 250 mm, working pressures from 10,51 bar to 25 bar and operating temperatures from 175 C to + 45 C. 1 1 bar = 0,1 MPa.
