Some further comment is necessary on the methods of extrusion used for tube and hollow profiles. In particular seamless extrusion produces a product that does not contain any seams or weld lines in the product cross-section. On the other hand extruded products manufactured using a porthole or bridge die will contain at least one longitudinal weld or seam. The presence of such welds or seams can be a major concern on products that are to be used for e.g. pressure vessels since the weld/seam could lead to premature failure of the vessel under pressure. NOTE 2 In addition despite rigorous process control during the extrusion process, there is no definitive non-destructive test method that can provide total assurance of the integrity of the welds in the product cross-section. In view of the safety implications of using porthole products, it is necessary to provide guidelines in this standard as to the permitted product areas where porthole products may or may not be used. NOTE 3 It needs to be highlighted that, beside the limits for nominal size DN and thickness t, Tables 4 and 5 provide additional limitations regarding pressure PS, volume V and testing procedures. The equipment supplier can decide to use porthole extrusion for products exceeding the stated limits/hazard categories, but this can only be done after written agreement between supplier and purchaser, and provided that adequate quality assurance/testing procedures are agreed. 5.1.3 Quality control The manufacturer/supplier shall be responsible for the performance of all inspection and tests required by the relevant European standard and/or the particular specification prior to shipment of the product. If the purchaser wishes to carry out an inspection prior to shipment, this shall be agreed with the supplier and the request shall be stated on the original order. 5.2 Orders or tenders The order or tender documents shall define the product required and contain the following minimum information: a) the type and form of the product. In the case of tube whether extruded, cold drawn or coiled, it is also essential to state the method of extrusion to be used i.e. seamless or porthole (see also point i) below); b) reference to this particular Standard EN 12392; c) the dimensions and shape of the particular product required; SIST EN 12392:2016
