BSI as a member of CEN is obliged to publish EN 10217-2:2019 as a British Standard. However attention is drawn to the fact that during the its approval. development of this European Standard the UK mittee voted against
The UK mittee draws users' attention to the fact that BS EN 10217Parts 1 to 7 are product standards and are therefore intended to assistspecifiers designers and other users of the documents by setting out a series of tube and pipe grades intended for use in pressure applications.The non-alloy and low-alloy grades in Parts 1 to 6 are parable (interchangeable) with seamless grades of the same designationsin BS EN 10216 Parts 1 to 4. Similarly the stainless grades in Part 7are parable to seamless grades of the same designations in BS EN 10216 Part 5.
It should be noted that guidance onmaterial suitability for specificapplications is not provided in product standards. It is thereforeimportant that specifiers designers and other users of the documents understand the differences between the types and characteristicsof the welded pressure pipes covered in the standards so that the appropriate type and grade can be specified or selected for theapplication concerned.
In particular it should be noted that althoughBSEN13480supportsessential requirements of EU Directive 2014/68/EU (the Pressure Equipment Directive or PED) the TR1 grades in BS EN 10217-1 areStandard). This is because in particular they do not meet the essential not suitable for use under the PED (as indicated in Table 4 of therequirements of the Directive in respect of ageing (determined by therequirements). In addition most HFW TR1 grades imported into the UK chemical position) or ductility (specified as minimum Charpy impactare cold-formed and hence the weld seam will not have been heat-treatedlead to cracking if the tube is subjected to additional processing The which means that the weld area is likely to be highly stressed which canUK mittee therefore remends that users do not use any HFW products certified or sold as being of BS EN 10217-1 TR1 grade. Instead to ensure PED pliance the UK mittee remends that hot-most pressure applications although BS EN 10217-1 TR2 grades may be finished HFW tubes in accordance with BS EN 10217-2 should be used forconsidered in some cases.
As BS EN 10217 stee tubes and pipes can be used for a whole range of applications from building services to critical requirements involvinggas or chemicals it is important that the specifier designer or userselects themost suitable tubeorpipetypeand gradefromthe seven parts of the standard provided.
