46、 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: a non-oil-resistant cover; Class B: an oil-resistant cover.Both types and classes can be either of the following:a) electrica
47、lly 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 steam and hot water condensate and shall be uniform in quality, free of porosity, air holes, foreign inclusions and other def
48、ects.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 mechanical 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 tolerances7.1 Dia
