    Vessel Repair with no U1 form

    I've been asked to build a new shell section for a "BEM" type exchanger & reuse the existing channels. Problem is he has no U1 data report form....is this legal ? Can I build this as the original or is it deemed new conctruction ? Thanks

    SA 516 Gr 70 HIC Plate

    Can someone tell me at what level of H2S do we have to use HIC plate. I have an exchanger with a stream containing 100ppm H2S 140F to 200F @ 60psia. Is there a table or chart that will tell me this ? Thanks KWG

    Low Temp Impact Testing

    I have to build a liquid nitrogen exchanger -350F design. I'm using SA240-304. Question : looking at (Div 1) UHA-51(g) does this exempt you from all impact testing or just base material ?
