You should refer to the PED Guidelines (make a Google search on that), which is a 255 page document from the EU Commission. It does not state directly the 27J, but 27J is a common used criteria in European materials (EN materials). Also your WPS’s should be qualified to show compliance with that requirement, but that will come automatically because your WPS’s will need to address that they comply with PED 97/23/EC. There are no impact test requirements on austenitic stainless steel – se guidelines.   You will find in the guidelines, that you need to have “Particular Material Assessments” (PMAs) made for non-European Materials, these should be verified by your selected Notified Body for the CE-marking.   For information: It is rather limited what your Notified Body may guide; their role is not to guide but to verify (and basically they cannot verify that they guided correctly themselves).     Yours sincer...

3LPE is commonly used as an external pipeline coating for offshore and onshore carbon steel pipelines. Assuming your seawater contains oxygen (it normally does) then a carbon steel pipeline will be subject to internal corrosion, and notably at the welds. The alternatives are plastic lined carbon steel, GRE or polyethylene pipe. The stainless steel alternatives which are considered to be seawater resistant are 6Mo or super-duplex (PREN greater than 40).   From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of Sandeep Karnwal Sent: 27 May 2014 03:43 To: materials-welding@googlegroups.com Subject: Re: [MW:20886] Pipeline selection criteria   Low Mn contain coating On 26-May-2014 11:16 AM, "Saidur Rahman" < saidur04cuet@gmail.com > wrote: Dear Experts, Normally  Cross-coutry pipelines are 3LPE coated (except marshy land).

1                      The document you have to comply with in the UK is not the 'Pressure Equipment Directive' which is a document prepared by the European Union which has to be enacted by the national governments into their law. The document you have to comply with is the enactment of that into law in the UK which is Pressure Equipment Regulations 1999 (SI 1999/2001) (PER) PER came into force on 29 November 1999 and was amended by SI 2002 No 1267 which came into force on 30 May 2002. 2                      I attach a useful guide which tells you what the PED and PER are all about. Apart from correctly identifying the hazard categories you must also ensure that there is the correct level of third party approval, surveillance and approval of design and fabrication documentation and site sup...

If the steel is for new construction and you have material available then run the standard SSC and HIC testing for full qualification and ensure that the welding procedure is qualified to meet NACE MR 0175 / ISO 15156.  If it is already in service then review the weld procedure to confirm that it was done per NACE MR 0175 / ISO 15156 and/or measure the hardness of the weld and HAZ to ensure that is below the maximum hardness allowed per the NACE MR 0175 / ISO 15156 requirements of Table A.1 of NACE MR 0175 / ISO 15156-2 On Friday, May 23, 2014 2:00:20 AM UTC-5, Ri@z wrote: Dear All, I hav SA 516 gr 60 , Non nace material.

Thank you for the reply. If anyone have more information regarding where exactly the impact testing values are specified in PED and are these differ as per material. I know the directive PED 97/23/EC, however the requirements are very general.   Is there any BV member of our group can guide me in detail.

I was told there is equipment which can be used for stress relief, particularly helpful when coming to SS welding when PWHT is not a good option. This must be done during the welding process, not post welding like PWHT.   For welding being carried out with CS & LA materials, it can achieve approx. 90% of what a PWHT can do if it be being used correctly. For welding being carried out with SS materials, it should able to achieve the same level of stress relief like CS/LA materials.   Let me know if anyone have any interest as demonstration can be arranged.     Thanks, KL Chung KTM Taiwan.   From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of Arunachalam A Sent: Wednesday, 28 May, 2014 11:22 PM To: materials-welding@googlegroups.com Subject: Re: [MW:20924] PWHT for stainless steel weld joint   If you carry out the PWHT, then MDMT for the vessel is reduced to Minus 29 Deg C.   Regards,     On ...
