Phakathi "kwezimoto" ezidingekayo ukuhambisa impahla ethile, enye yezinto ezivame kakhulu amapayipi.Ipayipi lihlinzeka ngokuthuthwa kwegesi noketshezi okunezindleko eziphansi nokuqhubekayo.Namuhla, kunezinhlobo eziningi zamapayipi.Imiklamo iyahlukahluka ngesilinganiso, ububanzi, ingcindezi, nezinga lokushisa lokusebenza.
Amapayipi amakhulu, enethiwekhi yosizo, ezobuchwepheshe, emikhumbi (umshini) ayahluka ngesilinganiso.Ake sibhekisise kabanzi inhloso nezigaba zamapayipi ahamba phambili kanye nezobuchwepheshe.
Isiquamapayipi.Ukuqokwa kanye nesigaba
Amapayipi e-trunk ayisakhiwo sobuchwepheshe esiyinkimbinkimbi, esihlanganisa i-fila yepayipi elingamakhilomitha amaningi, iziteshi zokumpompa igesi noma uwoyela, ukuwela imifula noma imigwaqo.Amapayipi amakhulu athutha uwoyela nemikhiqizo kaphethiloli, igesi ye-hydrocarbon ewuketshezi, igesi yamafutha, igesi yokuqala, njll.
Wonke amapayipi amakhulu enziwa kuphela ngobuchwepheshe be-welding.Okusho ukuthi, ebusweni banoma yiliphi ipayipi elikhulu ungabona i-spiral noma i-seam eqondile.Njengempahla yokwenziwa kwamapayipi anjalo, insimbi isetshenziswa, njengoba iyinto eyongayo, ehlala njalo, ephekwe kahle futhi enokwethenjelwa.Ngaphezu kwalokho, kungaba insimbi yesakhiwo "yakudala" enezakhiwo ezikhethiwe zemishini, insimbi enekhabhoni ephansi noma ikhabhoni ukuze ibe sezingeni elijwayelekile.
Ukuhlukaniswa kwamapayipi alayini omkhulu
Ngokuya ngengcindezi yokusebenza epayipini, amapayipi amakhulu egesi ahlukaniswe amakilasi amabili:
I - ekucindezelekeni kokusebenza okungaphezu kuka-2.5 kuya ku-10.0 MPA (ngaphezu kuka-25 kuya ku-100 kgs/cm2) kuhlanganisiwe;
II - ekucindezelweni kokusebenza okungaphezu kuka-1.2 kuya ku-2.5 MP (ngaphezu kuka-12 kuya ku-25 kgs/cm2) kuhlanganisiwe.
Ngokuya ngobubanzi bepayipi labelwe amakilasi amane, mm:
I - nge-diameter evamile engaphezu kuka-1000 kuya ku-1200 ehlanganisiwe;
II - okufanayo, ngaphezu kwe-500 kuya ku-1000 ifakiwe;
III kuyefana.
IV - 300 noma ngaphansi.
Amapayipi ezobuchwepheshe.Ukuqokwa kanye nesigaba
Amapayipi ezobuchwepheshe amathuluzi okuhlinzeka ngophethiloli, amanzi, izinto zokusetshenziswa, imikhiqizo ecishe iqedwe kanye nemikhiqizo ehlukahlukene esetshenziswa ekukhiqizeni embonini yezimboni.Amapayipi anjalo athutha izinto ezingavuthiwe kanye nemfucuza ehlukahlukene.
Ukuhlukaniswa kwamapayipi ezobuchwepheshe kwenzeka ezicini ezifana nalezi:
Indawo:inter-purpose, intra-branch.
Indlela yokubeka:ngaphezulu komhlaba, phansi, ngaphansi komhlaba.
Ingcindezi yangaphakathi:ingcindezi (self-ute), vacuum, low pressure, medium pressure, high pressure.
Izinga lokushisa lezinto eziphathekayo:cryogenic, kubanda, evamile, efudumele, kushisa, overheated.
Ulaka lwento ethuthayo:abangenalo ulaka, abanolaka (abancane-abanolaka), abanolaka olumaphakathi, abanolaka.
Izinto eziphathekayo:amapayipi omusi,amapayipi amanzi, amapayipi,amapayipi egesi, amapayipi omoya-mpilo, amapayipi kawoyela, izintambo ze-acetyleno, amapayipi kawoyela, amapayipi egesi, amapayipi e-asidi, amapayipi e-alkaline, amapayipi e-ammonia, njll.
Okubalulekile:insimbi, insimbi enenamathela yangaphakathi noma yangaphandle, evela ezinsimbi ezingenayo insimbi, insimbi ecijile, evela ezintweni ezingezona ezensimbi.
Uxhumano:engahlukaniseki, isixhumi.
