Dear Friends

 

I have a query and request you to give your opinion

 

a)      One of the  Heat exchangers, we want to use  U tubes  of Inconel 690 having  OD of 13mm and 19mm  with thk of 1.2mm

b)      Straight tubes shall be purchased and bending shall be carried  in house  or at tube manufacturer

c)       I want to know does it require any solution annealing after U bending ? and if Yes  what will be cooling media and method to avoid flattening of tube near bend

d)       What are the testing require to ensure correct metallurgical , physical and  mechanical properties

 

Warm regards
