Hi all,

I was looking for some information in API STD 521 and found a reference for sizing tailpipes and laterals based on rated flow.

Actually, I was originally under the impression that laterals and tailpipes were one in the same (single-source piping directly downstream of relieving device).

Yet I came across a information on the other forum (http://www.eng-tips....=146511&page=65) that suggest they are different. I will quote it below,


QUOTE

"Tailpipes to me would be the piping directly downstream of the PSV. The lateral is typically a subheader that collects discharges from various PSVs and routes them into the main flare header.

It's not a hard and fast distinction in my opinion."


In my humble opinion, the above quote is kind of make sense to me, because I can't found in API STD 521 any statement that related with sizing of flare subheader. Is lateral = flare subheader? Please kindly confirm this.

Finally, if someone could offer a description of laterals & tailpipes and also a distinct difference between them , I would appreciate it.

thank you
regards,
bernath
