We have tested 3/4" 800 globe valve upto 225 kg/cm2. (The purpose was to make testing assembly that can test upto 140 kg/cm2. As we have no availibility of 1500 rating valves). There was no leakage through glands and bonnet flange. The valve was tested in open and close conditions. The question...
We have a spare BLIND FLANGE of SA-182 F51 UNS NO. S-31803 (DUPLEX). Material of tubes of E-2002/E-3002 and E-3801 is A-789 UNS No. S-31803 that seem compatible with BLIND FLANGE material. Can we use Blind Flange material to prepare plugs for our exchangers?
CAN WE USE SS316L PLUGS TO WELD ON A-789 S31803? FOR WELDING WHAT FILLER WIRE TO BE USED? CAN WE USE ER-2209?
INFORMATION WOULD BE APPRECIATED.
