BSI 05-1999,Foreword,This Part of BS 6501 having been prepared under the direction of the Piping,Systems Components Standards Policy Committee supersedes BS 6501-2:1988,which is withdrawn. This edition introduces technical changes but it does not,reflect a full review or revision of the standard, which will be undertaken in due,course. In this revision, a new nominal pressure of hose assembly of PN 0.25 has,been added.,BS 6501-1 covers the requirements for corrugated flexible metallic hose,assemblies. This Part covers the requirements for strip-wound flexible metallic,hoses and hose assemblies. BS 669-1 contains details of construction of leak-proof,strip-wound hose assemblies for use with gas appliances.,Strip-wound metallic hose assemblies, as a part of pipework systems, are used to,convey non-searching liquids, powders and gases under various pressure and,temperature conditions in applications where, because of the need to accept,displacement during operation, the use of conventional rigid piping is precluded.,Strip-wound assemblies may also be used as temporary pipelines for connecting,fixed and movable installations during loading/discharge operations.,Strip-wound hose, compared with other types of hose, is extremely robust and it,can accept both lateral and axial displacements. It is well suited for manhandling,powder transfer, engine exhaust and armouring applications. It also has intrinsic,electrical conductivity. It is not suitable for highly penetrating liquids and,extremes of temperature or pressure.,Since the flexibility of strip-wound hose is achieved by sliding, fatigue is of lesser,importance than with corrugated hose.,Asbestos has been specified for certain of the hose constructions covered by this,Part of BS 6501 as the only packing material that can meet the duty required,although alternative materials are being investigated.,The manufacture of all asbestos based products is covered by the requirements of,the Control of Asbestos at Work Regulations 1987, introduced on 1 Marc……
