Materials are selected for process equipment based on the specific needs and service requirements of the item of equipment concerned, and the need for them to operable for that service. It is not just a question of applying a corrosion allowance. For example you may need to apply clad or corrosion resistant materials in that item of equipment. It sounds as if you may be writing a scope of work and you want to set a minimum standard for the work. In that case you could refer to an internationally recognised document/guide which lays down the basis for material selection for your industry and is used in your region of the world.   From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of Himan Nikdin Sent: 30 April 2015 07:44 To: materials-welding@googlegroups.com Subject: [MW:23191] Corrosion Allowance for equipment   Dear experts   Good day!!   In all corrosion prediction models for process units in oil and gas the predicti...

Dear experts   Good day!!   In all corrosion prediction models for process units in oil and gas the prediction model calculate the corrosion rate for piping system and whereas the process condition in equipment such as the vessels, towers and exchangers is totally different with piping system the evaluation model is not applicable to predict the corrosion rate and calculate the corrosion allowance. So I want to know this phrase is correct or not; "The corrosion allowance for equipment is at least equal to the worst corrosion allowance of pipes which connected to equipment" . If yes is there any specific code to verify the above phrase? Thanks Himan Nikdin

Sorry for the error..what I intended to suggest  was the dissimilar combination of PIG1 and P1G2 can be achieved if both pipes are used..

Hi, What you have mentioned is one of the option. or you can directly weld pipe to flange and carryout the procedure qualification for which you may have to procure additional flanges. Regards, L.

In that case first  PQR on 10mm plate without PWHT which will qualify from 1.5 mm to 20mm . Second PQR on say 30mm with PWHT which will qualify from above 20 mm to 60 mm considering PWHT requirements for CS as per B 31.3. And in WPS , in QW 407 section  need to mention that PWHT is applicable for only above 20mm.

There is no reason for 2 pqrs. If the design and construction code does not have any impact test requirements you can do your pqr using only pno1/gropu no 1 material. Pqrs are usually done with plates since in Asme code diameter is neither essential nor supplementary essential variable Sent from my BlackBerry 10 smartphone.
