It has to be a non-flammable liquid, and also non-lethal, some customers ask in their specification that the water is free of salts and minerals, that you show by a documented laboratory test, but in general I would recommend that you review UG-99 of Section VIII DIV.1 of the BPVC ASME, in case this is your Construction Code.    Regards!  .  El vie., 31 ago. 2018 a las 8:03, Temburu Chiranjeevulu (< chiru.qaqc@gmail.com >) escribió: Dear Experts, What are the parameters of water sample, we have to check before hydro static test.

Dear Experts, I would like to know details of Vertical Seam Cladding on Tanks. We carried out cladding  previously which was conventional method but this method we have not done. Would like to know what is  the method to carry out and how the sheets to be fabricated.  Thanks in advance.

Hi All. I have found recently total specification of "GS EP PVV 618" that say 3mm/year(ideally 1-1.2mm/year) for acceptance of G28. Now does any body know why this amount specified in spite of other documents (that mentioned .8 or .9 mm/year ) and when ideally amount applicable for setting criteria? Regards.

Hi,      The sample preparation for clad materials is always debatable and should mostly be addressed by end user specification. It should be dictated from the fact that service fluid is in touch with the final clad layer and considering the corrosion allowance. However you may check the entire cross section corrosion rates for your reference. Thanks & Regards, Harish On Aug 29, 2018 12:10 PM, "Ali Asghari" < asgharialigl@gmail.com > wrote: Dear All. Does anybody have any experiences or instruction for preparation of sample for G28?is there any requirement to remove clad material from surface and go through it or not? this question arises from this point that IGC comes from carbide & inter metallics that mostly possible in diluted area and also accepted corrosion rate is about 0.9 mm/year for 625. Now is it reasonable to prepare sample from interface or without removing of thickness and take it from surface? Regards.   -- https://materials-welding.blog...

Dear Harish. Thank you for responding. "The intent is to test a specimen representing as nearly as possible the material as used in service. The specimens should be cut to represent the grain flow direction that will see service, for example, specimens should not contain cross-sectional areas unless it is the intent of the test to evaluate these. Only such surface finishing should be performed as is required to remove foreign material and obtain a standard, uniform finish as specified in 6.4. For very heavy sections, specimens should be maintained to represent the appropriate surface while maintaining reasonable specimen size for convenience in testing. Ordinarily, removal of more material than necessary will have little influence on the test results." this paragraph is taken from G28 and only said about the surface area but didn't talk about any thing about cross section or through thickness orientation of sample especially for weld deposited over laid that have a metallurgic...
