35、ick-release coupling shall not be used under any circumstances.The end fittings used with the hose shall be of a type that provides for tightening-up during service; for example, a clamp type to compensate for creep of the rubber compounds in the hose.NOTE 1 Where superheated steam conditions occur,

36、 the service life of the product can be reduced.NOTE 2 Vacuum caused by shutting off the hose assembly at both ends can precipitate “pop-corning” or separation of the lining.5 ClassificationThis document specifies two types of hoses/hose assemblies to convey saturated steam and hot water condensate.

37、Type 1: low-pressure steam hose, maximum working pressure 6 bar, corresponding to a temperature of 164 C.Type 2: high pressure steam hose, maximum working pressure 18 bar, corresponding to a temperature of 210 C.NOTE 1 bar = 0,1 MPa.Each type of hose is divided into either of the following: Class A:

38、 a non-oil-resistant cover; Class B: an oil-resistant cover.Both types and classes can be either of the following:a) electrically bonded, marked “M” (see Clause 11);b) electrically conductive, marked “” (see Clause 11).6 Materials and constructionHoses shall consist of a lining which is resistant to

39、 steam and hot water condensate and shall be uniform in quality, free of porosity, air holes, foreign inclusions and other defects.The reinforcement shall be textile for Type 1 and steel wire for Type 2, either braided, spiral or cord ply construction.The cover shall give protection against mechanic

40、al damage and be resistant to heat, wear and environmental effects due to weather and short-term chemical exposure. It shall be pricked equally around the periphery and along the whole length of the hose in order to relieve any pressure built-up between the plies and the cover.7 Dimensions and toler
