BS EN 10208-2:2009

In this case, both internal and external weld reinforcements shall be ground flush to match the parent pipe contour in sn immediate area and on both sides of the reference notches. Lengths of pipe with outside diameters D smaller than ,3 mm shall be weighed either individually or in convenient lots, at the discretion of the manufacturer. Circular test pieces machined from an unflattened sample may be used by agreement. The percentage elongation after fracture shall be reported with reference to a gauge length of 5,65 0S where S0 is the initial cross section of the gauge length.

After grinding the remaining wall thickness in the dressed area shall be checked for compliance with 8. It includes more stringent quality and testing requirements than those in EN An approval of the quality system may 01208-2 agreed. The verification of compliance with this requirement by means of an ultrasonic test conducted in the pipe mill, at the discretion of the manufacturer either prior to welding of the strip edges in accordance with EN to acceptance limit U2 or after welding on the area adjacent to the weld seam in ac- cordance with EN to acceptance limit U2 shall only be carried out by agreement.

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.

Test method ISO Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN Management Centre or to any CEN member.

For cold formed pipes every hardened place with the length of more than 50 mm should be tested in any direction. The axis of the notch shall be perpendicular to the 1020-2 surface.

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 10208–2 of level 1 and 2 non- destructive 1020-2 personnel EN By agreement, other approved measuring devices may be used. For details of these and other benefits contact Membership Administration. By agreement, fluoroscopic methods are permitted, but only when the manufacturer can demonstrate equivalence to the X-ray film technique.

For example, rich gas or two-phase fluids may require additional testing to be carried out. General guidance for arc welding ENWelding — Recommendations for welding of metallic materials — Part 2: The determi- nation of out-of-roundness of pipe ends shall be based on corresponding measurements of the inside or out- side diameters depending on the manufacturing process.

NOTE 3 Thermomechanical forming leading to the delivery condition M may include processes of increased cooling rates without or with tempering including self-tempering but excluding definitively direct quenching and quenching and tempering. Method of test at ambient temperature EN It supersedes BS EN Secondly, many purchasers impose requirements additional to the basic standard, for instance concerning toughness and non-destructive inspection. It includes more stringent quality and testing requirements than those in BS EN Where appropriate, the purchaser should contact the manufacturer for more detailed information.
