Re: [MW:24521] Corrosion in CRA pipes

Ni based alloy 825 is used to mitigate certain damage mechanisms, however fabrication of these alloy shall be performed with due care (similar to duplex and super duplex)  Please avail service data,  handled stream,  I suggest hydrocarbon with produced water or water injection service  A.E Material and corrosion engineer  Sent from Yahoo Mail on Android From:"berry gamaliel" <mechberrystallion@gmail.com> Date:Sun, 13 Mar, 2016 at 5:57 am Subject:[MW:24509] Corrosion in CRA pipes Dear Experts  In our project we are using CRA pipes, API 5L Grade B, thk- 35 mm. cladded with UNS00825  thk-5mm.  Due to improper preservation of spools grinding and machining wastes deposited or setteled inside the spools and oxidation and corrosion started in a minor way.  Please suggest whether chemical cleaning is required to to remove the minor corrosion or as it is a corrosion resistance alloy pipes will it withstand the corrosion.  Another clarification too as it is a Corrosion resistance alloy why it cannot resist or prevent corrosion from grinding and machine wasted and during the service condition highly corrosive fluids will pass though it so how it will withstand that.  Please clarify experts.  -- Regards Berry Gamaliel -- Regards Berry Gamaliel -- http://www.linkedin.com/groups/MaterialsWelding-122787?home=&gid=122787&trk=anet_ug_hm The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents. --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.
