It includes more stringent quality and testing requirements than those in EN 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. NOTE 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 EN .
One sample tube shall be taken per test unit. For comparison with the requirements in Table 6 and 7, the measured energy shall be converted to the impact energy KV in J using the formula: Secondly, many purchasers impose requirements additional to the basic standard, for instance concerning toughness and non-destructive inspection. Iron and steel pipes.
These limits refer to the gap between the extreme point of the deviation and the prolongation of the normal contour of the pipe. The weld reinforcement shall be removed from both faces.
NOTE 2 The abbreviated form of this delivery condition is M included, where applicable, in the steel name. 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.

For grades with values higher than 0,43 a max. The selection of the requirement class depends on many factors: SS-EN Replaced by: 102088-2 type of pipe and the type of heat treatment as given in the steel name shall be specified by the purchaser.
In this case, both internal and external weld reinforcements shall be ground flush to match the parent pipe contour in the immediate area and on both sides of the reference notches. In such a case, an ultrasonic test conducted in the pipe mill, at the discretion of the manufacturer either in the flat form prior to welding in accordance with EN to acceptance limit U2 or in the as-welded pipe form in accordance with EN to acceptance level U2, shall be used.
When trimming, the wall thick- ness shall not be reduced below the minimum specified. To take this into account, the following formula shall apply: Please note that the selected standard is invalid. An approval of the quality system may be agreed.

Cold forming and reduction with hot tensioning at controlled temperature so as to achieve a normalized state. Pipes of requirement class B BS EN is the European standard that specifies the technical delivery conditions for seamless and welded steel pipes for the on land transport of combustible fluids primarily in gas supply systems but excluding pipeline applications in the petroleum and natural gas industries.
Steel pipes for pipelines for combustible fluids – Technical delivery conditions – Part 2: The orientation and size of the test enn shall be as follows: Where dressing is carried out, it shall be verified by any appropriate NDT method that the imperfections have been completely removed. 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.
In cases of dispute, the analysis shall be carried out by a laboratory approved by both parties. EPRG recommendation for crack arrest toughness for high strength line pipe steels.
