Dear All,
In one of the piping specification following information is given (I have written exactly in the same manner it is written in the specs)
* Rating / Finish = CL300 RF 125 AARH (Note.1) [ Note1- AARH= Arithmetic Average Roughness Height]
* Basic Material = Carbon Steel
* NDE = 10 %
* PWHT = N
* Nominal Corrosion Allowance = 1.5mm
* Design Conditions = Max.Temp.- 380 °C / Max.Press. = 14 barg [ Extreme minimum temperature = 6°C ]
* Joint Construction = SB-SW / LB-BW
In the specs the meaning of the abbreviations are not given. I presume these would be the standard abbreviations used by piping engineers. I could understand it but I am not 100% sure. Please Help me.
1) What is NDE ? Is it about Non-destructive testing of weld joints
2) What is PWHT (Is it Pre-weld heat treatment)
3) What could be the meaning of SB-SW / LB-BW ? (Is it Short Bore - Socket Weld / Long Bore - Butt Weld )

Thanks & Regards,
VISHAL KHADKE

SB-SW - SmallBore / Socketwelded
LB-BW - LargeBore / Buttwelded
Reality is a trigger word and we're quickly losing touch...
