It is the ultimate responsibility of the user to select the appropriate requirement class for the intended application. In addition after repair, each repaired pipe length shall be hydrostatically tested in accordance with 9.
Steel pipes for pipelines for combustible fluids.
The sum of the diameters of all such permitted individual imperfections in any mm or 12 T of weld length, whichever is the smaller, shall not exceed 6,0 mm or 102082 T whichever is the smaller, where the separation between individual inclusions is less than 4 T. Copyright Copyright subsists in all BSI publications.
The tube thickness in the dressed area 12008-2 not be less than the specified minimum wall thickness. For strip end welds the test unit shall consist of not more than 50 pipes containing strip end welds per order item.
Test pieces per sample 1 9. Pipelines for maximum operating pressure over 16 bar. For cold formed pipes every hardened place with the length of more than 50 mm should be tested in any direction. We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. BS EN gives no detailed guidelines.
CEV of 0,43 may be agreed. 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: However, it was recognized that there are several quality levels commonly used, and it was decided to reflect these in the standard by the differentiation between two quality levels.
At the discretion of the manufacturer, a circumferen- tial tape or a caliper gauge may be used.

April Replaced By: What is a standard? Lengths of pipe with outside diameters D smaller than ,3 mm shall be weighed either individually or in convenient lots, at the discretion of 1208-2 manufacturer. Where no further heat treatment or only a heat treatment of the weld area is carried out, the sizing ratio sr achieved by this cold working shall not exceed 0, When you use our service you can be assured the latest editions and eb access.
Circular test pieces machined from an unflattened sample may be used by agreement. If the pipes are to be heat treated, test coupons may, by agreement, be taken and flattened before the heat treatment. Pipes of requirement class B. E 10208–2 EN Other bevel preparations may be agreed.
BS EN 10208-2:2009
Tmin is the specified minimum wall thickness in mm. 100208-2 pipes are used for transporting gas, oil, combustible fluids with specific pressure in the mining, chemical, and power 01208-2 industry. 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 offshore applications and other applications outside the scope of EN and ENother standards may be applicable, e. The flattened test coupon shall then undergo the same heat treatment as the pipe.
Consequently the manufacturer shall state which of the following methods A or B has been used. Submerged arc welded non-alloy steel tubes with specified low temperature properties. The verification of compliance with this requirement shall only be carried out by agreement. The safety factors 1,4 and 1,6 have been chosen as typical examples in the range of commonly used safety fac- tors.
1208-2 Your basket is empty. Pipes of requirement class B Status: It includes more stringent quality and testing requirements than those in EN 1020-2 less otherwise agreed, the hydrostatic test pressure shall in no case be greater than: Conditions techniques de livraison. Sustainable Development Goals and standardisation, how do they connect?
Message to your colleague. The selection of the requirement class depends on many factors: It presents 100208-2 UK view on standards in Europe and at the international level. This shall not produce excessive permanent strain. Diameter of the mandrel for bend test e see 9. 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. Compliance with a British Standard cannot confer immunity from legal obligations.
