ASTM A179 / ASME SA179 Heat Exchanger Tubes - BLOG

Selelekela

ASTM A179 / ASME SA179 e hlalosa li-tubes tse se nang moroko, tse batang-tse huloang, tse tlase{3}} tsa carbon steel tse etselitsoeng ho fetisa mocheso hantle le ho sebetsa ka mokhoa o tšepahalang. Ka bonyane-kaho ea lebota le taolo e thata ea tšepe, li-tubes tsena li sebelisoa haholo ho li-heaters le li-condenser ho pholletsa le liindasteri tsa ho hloekisa, tsa petrochemical le tsa motlakase.Octal Pipe e fana ka li-tubes tsa A179/SA179 bakeng sa EPC ea lefatše lohle le baetsi ba lisebelisoa, e tšehetsang li-tubes le U{0}}likopano tsa ho kobeha.

Q1: ASTM A179 / ASME SA179 tubing e sebelisetsoa eng?

A1: Mohatsela o se nang morolo-o huloang ka tlaase-liphaephe tsa tšepe tsa k'habone bakeng sa li-heaters, li-condenser, le lisebelisoa tse tšoanang tsa ho fetisa mocheso{3}}.

Q2: Na ASME SA179 e lekana le ASTM A179?

A2: SA179 ke mofuta oa ASME oa ASTM A179; netefatsa khoutu/khatiso e hlokoang ke projeke ea hau.

Q3: ASTM A179 e koahela boholo ba mofuta ofe?

A3: Ka tloaelo 1/8" ho isa ho 3" (3.2–76.2 mm) bophara ba kantle.

Q4: Ke liteko life tse atisang ho hlokoa bakeng sa li-tubes tsa A179 / SA179?

A4: Ho thatafala hammoho le licheke tsa ductility (ho batalatsa / ho phatloha) le tlhahlobo ea hydrostatic kapa NDE, ho latela tatellano/spec.
