Iyini ipayipi?
Ipayipi liyisigaba esingenalutho esinesigaba esiyindilinga sokuthutha imikhiqizo, okuhlanganisa uketshezi, igesi, ama-pellet kanye nophuphu, njll.
Ubukhulu obubaluleke kakhulu bepayipi ububanzi bangaphandle (OD) kanye nobukhulu bodonga (WT). OD minus 2 times WT (schedule) inquma ububanzi bangaphakathi (ID) bepayipi, okunquma umthamo wepayipi.
Iyini i-Tube?
Igama elithi tube libhekisela ezingxenyeni eziyindilinga, eziyisikwele, eziyisikwele neziyindilinga ezimboziwe ezisetshenziselwa imishini yokucindezela, ukusetshenziswa kwemishini, kanye nezinhlelo zezinsimbi.Amapayipi aboniswa ngobubanzi bangaphandle kanye nobukhulu bodonga, ngamasentimitha noma ngamamilimitha.
Amapayipi anikezwa kuphela ububanzi bangaphakathi (obungaguquki) kanye "neshejuli" (okusho ukujiya kodonga). Njengoba ipayipi lisetshenziselwa ukudlulisa uketshezi noma igesi, ubukhulu bomgodi lapho uketshezi noma igesi kungadlula khona cishe bubaluleke kakhulu kunobukhulu bangaphandle bepayipi. Ukulinganiswa kwepayipi, ngakolunye uhlangothi, kunikezwa njengobubanzi bangaphandle kanye nobubanzi obubekiwe bobukhulu bodonga.
Ipayipi litholakala ngensimbi egoqwe ngokushisa kanye nensimbi egoqwe ngokushisa ebandayo. Ipayipi ngokuvamile liyinsimbi emnyama (egoqwe ngokushisa). Zombili lezi zinto zingagaywa nge-galvanized. Kunezinto eziningi zokwakha ezitholakalayo zokwenza amapayipi. Amapayipi atholakala ngensimbi yekhabhoni, i-alloy ephansi, insimbi engagqwali, kanye nama-nickel-alloys; amapayipi ensimbi okusetshenziswa kwemishini ikakhulukazi ensimbi yekhabhoni.
Usayizi
Ipayipi ngokuvamile litholakala ngobukhulu obukhulu kunepayipi. Kupayipi, i-NPS ayifani nobubanzi bangempela, iyinkomba eqondile. Kupayipi, ubukhulu buvezwa ngamasentimitha noma ngamamilimitha futhi buveza inani langempela lobukhulu bengxenye engenalutho. Ipayipi ngokuvamile lenziwa ngezindinganiso eziningana zezimboni, zomhlaba wonke noma zezwe, okunikeza ukuvumelana komhlaba wonke, okwenza ukusetshenziswa kwezinto ezifana nezindololwane, ama-tee, kanye nama-coupling kube usizo kakhulu. Ipayipi livame ukukhiqizwa ngokwezilungiselelo ezenziwe ngokwezifiso kanye nosayizi kusetshenziswa ububanzi obubanzi bobubanzi kanye nokubekezelelana futhi lihlukile emhlabeni jikelele.
