Meaning of the abbreviations was created by vishal.khadke
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,
