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.
