This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Septemberand conflicting national standards shall be with- drawn at the latest by September Pipes of the highest quality. Attention ne drawn to the possibility that some of the elements of this document may be the subject of patent rights.
This standard specifies products with the same and additional strength levels and partly similar but not identical requirements as EN and EN and is with two additional annexes specifying deviating or addi-tional requirements also published as API Spec 5L eh. The frequency of testing is to be agreed. The Charpy impact energy requirements in this document have been derived from established data, in accordance with EPRG recommendations, and are intended to prevent the occurrence of long running shear fracture in pipelines transporting em, dry natural gas.
Tmin is the specified minimum wall thickness in mm. The templates shall have a length of a quarter of the specified outside diameter but max. Any manual NDT applied to local suspect areas dressed or not shall use the same test sensitivity, test parameters and acceptance level reference notch depth as used during the test which een deemed the pipe suspect.
BS EN 10208-2:2009
In the case of testing the weld joining two strip ends, the tested unit for every order number should not include more than 50 pipes. EPRG recommendation for crack arrest toughness for high strength line pipe steels. Firstly, the need was recognized to provide a basic quality level. Transverse test pieces shall be flattened. Pipe types and the manufacturing eb original material, plastic forming and thermal processing state.
Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. Other equivalent steelmaking processes may be used by agreement.

This document combines a wide range of product types, dimensions and technical restrictions in accordance with the functional requirements for gas supply systems referred to in BS EN Gas supply systems. In such a case, an ultrasonic test conducted in either the plate mill or the pipe mill and in the latter case, at the discretion of the manufacturer, in either the flat form or the pipe form, in accordance with EN to acceptance level U2 shall be used.
In such a case an ultrasonic test in accordance with EN shall be used. As indicated in Figure 4, one of the two test pieces taken from both end-of-coil locations shall be tested with the weld at the 12 o’clock position whilst the remaining two test pieces shall be tested at the 3 o’clock position. Diameter of the mandrel for bend test e see 9. Pipes of requirement class A.
The faster, easier way to work with standards. A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions. For grades with values higher than 0,43 a max. Every pipe should be subject to the test and it should be free of any leaks or eb. The maximum accumulated length of such permitted individual imperfections in any mm or 12 T of weld length, whichever is the smaller, shall not exceed 12,0 mm, where the separation between individual inclusions is less than 4 T.
If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be 10280-2. Details and advice can be obtained from the Copyright and Licensing Manager. This approach is common, for example, for transmission pipelines.
Al- ternatively, at the discretion of the manufacturer, each pipe may be paint stencilled on one end. Method of test at ambient temperature EN This shall not produce excessive permanent strain. The purchaser shall state, at the time of enquiry and order, which impact energy requirements, depending on the safety factor to be used, shall apply. For dents, dn length in any direction shall not ex- ceed one half of the pipe outside diameter.
It includes more stringent quality and testing requirements than those in EN Accept and continue Learn more about the cookies we use and how to change your settings. By agreement, fluoroscopic methods are permitted, but only when the manufacturer can demonstrate equivalence to the X-ray film technique. One sample em shall be taken per test unit.
D specified outside diameter; Dmin specified minimum outside diameter; T specified wall thickness; Tmin specified minimum 01208-2 thickness.
Ultrasonic testing of tube ends of seamless and welded steel tubes for the detection of laminar imperfections ENNon-destructive testing of steel tubes — Qualification and competence of level 1 and 2 non- destructive testing personnel EN The depth of groove resulting from 01208-2 the internal flash of HFW pipe shall not undercut the contour of the pipe by more than that given in Table Iron and steel pipes.
General guidance for arc welding ENWelding — Recommendations for welding of metallic materials — Part 2: Secondly, many purchasers impose requirements additional to the basic standard, for instance concerning toughness and non-destructive inspection.
Steels for seamless and welded pipes LNB 1.
It is the ultimate responsibility of the user to select the appropriate requirement class for the intended application.
Where internal machining or grinding is carried out, the angle of the internal taper, measured from the longitu- dinal axis, shall be not greater than: What is a standard? BSI offers members an individual updating service called PLUS which ensures that subscribers automatically eh the latest editions of standards.
In cases where the seal is made on the outside or inside diameter of the pipe the following for- mula shall apply: The axis of the notch shall be perpendicular to the pipe surface.
