For CS pipe ( 4â€) we take ERW but for killed CS we take seamless one . Other conditions being the same.
Service is atmospheric vent.
Pl. tell about discrepancy.
Thanks

In one spec descrip is :
Cl 150 RF , CS , 0.063" corrosion allowance
-20 to 750 F @ 285 to 95 psig
Pipe Moc : A 53 /A 106/ 5L / seamless/A 53 - B- ERW
Large Fit MOC ; CS A 234-WPB
Small Fit MOC : CS A 105 ( 1.5" & < )
Pipe ( 4" ) : A 53 - B-E , ERW , Std Wt , BBE
In other :
Cl 150 RF , Killed CS , 0.063" corrosion allowance
-20 to 750 F @ 285 to 95 psig
Pipe Moc : Killed CS A 106-B seamless
Large Fit MOC ; CS A 234-WPB
Small Fit MOC : CS A 105 ( 1.5" & < )
Pipe ( 4" ) : A 53 /A 106/5L- B , seamless , Std Wt , BBE
Manufacturing method of pipe differs in two cases. Why ?

I had asked this question sometime ago to a material engineer and this was what I was told:
A-106 B seamless pipe deoxidixed with addition at least 0.10%Silicon & A-53 B (seamless or welded pipe); deoxidized, partially deoxidized or nondeoxidized - since the strong deoxidizing elements, silicon and/or aluminum, are not controlled. The term "killed" originally referred to the appearance of the molten steel. Non deoxidized molten steels appear to boil and bubble (or act lively) as oxygen chemically reacts with the molten steel while the highly deoxidized steels appear still and quiet or "killed".
