Re: [MW:15089] RE: 15076] API 580 (Nov 2009) - RBI: Para 14.9(d)

Gents, In simple words: go for liquid phase technology as a substitute for gas one ! Sometimes, simple meaning gets complicated because of confusing framing of words. Boniface, thanks for your good explanation.

What it means is that liquid phase imposes lesser consequences than gas phase. In molecular theory, gas molecules travel faster, occupy more space, and exert more pressure than liquid molecules. Therefore, gas leaks are more explosive than liquid leaks.   Hope this help.     "Quality is the Bone, Be the Dog Always"   Boniface Obidike QA/QC Engineer Speciality Connectors & Pipes Drilling and Production Systems GE Oil & Gas Business Mail: Boniface.Obidike@ge.com Office: +234(1)4629400 Mobile: +2348163479738 Home: +2348039409934     From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of M.

I collect that gas leaks lead to explosions while liquid leaks are still leaks. For example during pressure tests we take more precautions when using air than with water.   Please pour in some logic to this topic.     Regards,   Muhammad Ali   -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/ http://www.linkedin.com/groups/MaterialsWelding-122787?home=&gid=122787&trk=anet_ug_hm   The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.     -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/ http://www.linkedin.com/groups/MaterialsWelding-122787?home=&gid=122787&trk=anet_ug_hm   The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
