33、ERNATIONAL STANDARD ISO 6134:2017(E)Rubber hoses and hose assemblies for saturated steam Specification1 ScopeThis document specifies requirements for two types of hoses and hose assemblies, low pressure with a maximum working pressure of 6 bar and high pressure with a maximum working pressure of 18
34、bar, made of rubber and hose fittings made of metal, designed to convey saturated steam and hot water condensate.Each type is divided into two classes having either an oil resistant or non-oil resistant cover.NOTE Information on the frequency of testing of hose assemblies in use and storage is given
35、 in Annex A and Annex B.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

43、tion of the lining.5 ClassificationThis document specifies two types of hoses/hose assemblies to convey saturated steam and hot water condensate.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
44、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) electrically bonded, marked “M” (see C
45、lause 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 defects.The reinforcement shall
46、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
47、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 Diameters, thickness of lining and cover, and bend radiiWhen determined in accordance with ISO 4671, the diameters, thickness of lining and cover,
48、 and the bend radii of the hoses shall conform to the values given in Table 1.ISO 6134:2017(E) 2 ISO 2017 All rights reservedBS EN ISO 6134:2017ISO 6134:2017(E)Table 1 Diameters, thickness and bend radiiDimensions in millimetresInternal diameter Outside diameter Thickness min.
