Faule In conjunction with VdT? When used at the temperatures indicated and with a working period of h, no intergranular corrosion occurs when tested according to this AD Merkblatt. If above-normal loadings are to be expected during the operation of the pressure vessel, this shall be taken into account by meeting special requirements. Regardless, i think you can figure it out. As long as uniformity and meeting the set requirements over the length of the strip have been proven to the relevant third party with an adequate mrekblatt of reliability, the test for strip is carried out on one test section per coil. Regardless, ax lot of engineers continue merkblaft follow legecy practices merkblatt though the rules have changed.

In cases of doubt or dispute, the latest edition of the German text only is valid. Bars and forgings made of austenitic or austenitc-ferritic steels as specified in DIN EN and DIN EN may be used with the applicable cross-sectional area given in these standards up to a maximum of mm for bars and mm for forgings.
In this case, consideration shall be given, as appropriate, to long-term elevated temperature values if no intergranular corrosion can occur and their suitability1 for the specified application temperature has been verified.
This also applies to the filler metal of welded tubes. For welded tubes3 , the procedures and personnel for manufacture and testing by the relevant third party shall be confirmed. An approval procedure e. V-Merkblatt Part 2 aligned with the manufacturing method shall exist that also contains the type and scope of the non-destructive testing.
The need for and the type of heat treatment shall also be specified. If the verification of suitability has led to a VdT?
V-Werkstoffblatt, see the Index of VdT? Welded tubes are those manufactured by qualified, mechanized welding procedures in continuous production from strip or in series production as a single length from lengths of strip. If not specified in the order, the manufacturer specifies the welding procedure.
Tubes or nozzles manufactured individually do not come within this definition. Steels conforming to SEW are tested according to the above standards depending on the product form.
Steels complying with other material specifications are governed by the stipulations of the suitability verification1. As long as uniformity and meeting the set requirements over the length of the strip have been proven to the relevant third party with an adequate degree of reliability, the test for strip is carried out on one test section per coil.
A reference shall be made in the inspection certificate to the verification of the uniformity over the strip length and the approval by the relevant third party. If agreed with the user, this test may be dispensed with. If agreed with the user, this test may be dispensed with the test shall be carried out according to DIN EN , option In addition, the following tests shall be carried out: 4.
If imperfections are found in the tubes tested in this way, all the tubes shall be tested in a non-destructive manner over their whole length. Testing of tubes made of steels covered by SEW is carried out in the same way. For tubes within a pressure vessel internal tubes 4 , the ultrasonic examination may be dispensed with.
This is generally the case also if the pressure in the tubes is greater than that in the pressure vessel.
