FLANGES TYPE BARREL- full or heavy 1

[IQIeduardo]

Hello

I was requested about flanges type barrel, sincerly i never have heard about these type of flanges.
1) Do you know How are they like? What other name are called?

Searching a little i found that there is two types:
full barrel & heavy barrel
2) What´s the difference between them?

This is the origin of my trouble: The full request was come to me in spanish,(i live in México) as next:
BRIDA TIPO BARRIL DE 16" DE DIAMETRO Y 12" DE PROYECCION, CLASE150, MATERIAL SA-266CL2

My translation is next:
16" FLANGE LONG WELDING NECK TYPE BARREL, clas150 SA-266 CL2
What do you think?
3) But i don´t know how to say "12plg DE PROYECCIÓN". what is it? Is it correct to say 12" projection??? Is it about lenght of neck?

If you speak no spanish, you haven´t to try translation, so answer question 1 please (a picture, a general infomation, a brochure o data sheet) and i will be able to deduce what PROYECCION means

I know that is more than one question, but i think that all are connected

Thanks and regards
