Amapayipi ensimbi afika ngezindlela eziningi nobukhulu. Ipayipi elingenamthungo liyindlela engashiselwe, eyenziwe nge-billet yensimbi egobile. Uma kukhulunywa ngamapayipi ensimbi ashiselwe, kunezinketho ezintathu: i-ERW, i-LSAW kanye ne-SSAW.
Amapayipi e-ERW enziwe ngamapuleti ensimbi ahlanganisiwe anokumelana. Ipayipi le-LSAW lenziwe ngepuleti lensimbi elihlanganisiwe elinomugqa oqondile. Ipayipi le-SSAW lenziwe ngepuleti lensimbi elihlanganisiwe elinomugqa oqondile.
Ake sibheke kabanzi uhlobo ngalunye lwepayipi, siqhathanise umehluko walo, nokuthi singayisebenzisa kanjani incazelo efanele ukuze ilandelwe.
Ishubhu yensimbi engenamthungo
Ipayipi elingenamthungo lenziwe nge-billet yensimbi engagqwali, efudunyezwa futhi imbozwe ukuze yakhe ingxenye eyindilinga engenalutho. Ngenxa yokuthi ipayipi elingenamthungo alinandawo yokushisela, libhekwa njengeliqinile kunepayipi elihlanganisiwe futhi alithambekeli kakhulu ekugqwaleni, ekugugulekeni nasekuhlulekeni okuvamile.
Kodwa-ke, izindleko ngethani lepayipi elingenamthungo ziphakeme ngo-25-40% kunelepayipi le-ERW. Ubukhulu bamapayipi ensimbi angenamthungo busukela ku-1/8 intshi kuya ku-36 intshi.
Ipayipi lokushisela elimelana nokumelana (ERW)
Ipayipi lensimbi le-ERW (ukushisela ukumelana) lakhiwa ngokugoqa insimbi ibe yipayipi bese kuxhuma iziphetho ezimbili ngama-electrode amabili ethusi. Lawa ma-electrode anomumo wediski futhi ajikeleza njengoba izinto zidlula phakathi kwawo. Lokhu kuvumela i-electrode ukuthi igcine ukuxhumana okuqhubekayo nezinto isikhathi eside sokushisela okuqhubekayo. Intuthuko yobuchwepheshe bokushisela iyaqhubeka nokuthuthukisa le nqubo.
Ipayipi le-ERW liyindlela engabizi futhi ephumelelayo yokufaka esikhundleni sepayipi lensimbi elingenamthungo, elihlala isikhathi eside kunepayipi le-SAW. Uma kuqhathaniswa nenqubo yokuxazulula esetshenziswa epayipini elihlanganisiwe le-arc elingaphansi komhlaba, amaphutha nawo awavamile ukwenzeka, futhi amaphutha okushintshwa okuqondile angatholakala kalula ngokuboniswa kwe-ultrasonic noma umbono.
Ububanzi bepayipi le-ERW busukela kumasentimitha angu-15 (15 mm) kuya kumasentimitha angu-21.34 (21.34 mm).
Ipayipi elihlanganisiwe le-arc elicwiliswe emanzini
I-LSAW (ukushisela umthungo oqondile) kanye ne-SSAW (ukushisela umthungo ojikelezayo) kuyizinhlobo zamapayipi ashiselwe nge-arc angaphansi komhlaba. Inqubo yokushisela nge-arc engaphansi komhlaba ikhiqiza ukuminyana kwamanje okuphezulu ukuvimbela ukushabalaliswa kokushisa okusheshayo kwengqimba yokugeleza nokugxila endaweni yokushisela.
Umehluko omkhulu phakathi kwamapayipi e-LSAW kanye ne-SSAW yindlela okuqondiswa ngayo i-weld, ezothinta amandla okuthwala ingcindezi kanye nokulula kokukhiqizwa. I-LSAW isetshenziselwa ukusetshenziswa kwe-voltage ephakathi kuya kwe-high-voltage, kanti i-SSAW isetshenziselwa ukusetshenziswa kwe-voltage ephansi. Amapayipi e-LSAW abiza kakhulu kunamapayipi e-SSAW.
Ipayipi elihlanganisiwe le-arc elingaphansi kwamanzi eliyi-longitudinal
Ipayipi le-LSAW lenziwa ngokwenza isikhunta sensimbi esigoqekile esishisayo sibe yi-cylinder bese sixhumanisa iziphetho ezimbili ndawonye ngokushisela okuqondile. Lokhu kudala ipayipi eligoqekile elinobude obude. Lawa mapayipi asetshenziswa kakhulu kumapayipi okudlulisa amafutha, igesi yemvelo, amalahle angoketshezi, ama-hydrocarbon, njll.
Kunezinhlobo ezimbili zamapayipi e-LSAW: umthungo owodwa we-longitudinal kanye nomthungo ophindwe kabili (i-DSAW). Ipayipi lensimbi le-LSAW lincintisana nepayipi lensimbi elingenamthungo kanye nepayipi lensimbi le-ERW elingamasentimitha angu-16 kuya kwangu-24. Embonini kawoyela negesi yemvelo, amapayipi e-LSAW e-API 5L anobubanzi obukhulu asetshenziselwa ukuthuthwa kwama-hydrocarbon amabanga amade futhi asebenza kahle.
Ububanzi bepayipi le-LAW buvame ukuba phakathi kwamasentimitha angu-16 namasentimitha angu-60 (406 mm kanye no-1500 mm).
Okungenamthungo - izinsalela zempi eziqhumayo - ukushisela i-arc engaphansi komhlaba okude - ukushisela i-arc engaphansi komhlaba okujikelezayo - ipayipi - ukushisela i-arc engaphansi komhlaba okujikelezayo
Ipayipi le-SSAW
Ipayipi lensimbi le-SSAW lakhiwa ngokugoqa nokushisela umucu wensimbi ngendlela ejikelezayo noma ejikelezayo ukuze kwenziwe ukushisela kube yi-spiral. Inqubo yokushisela ejikelezayo yenza kube nokwenzeka ukukhiqiza imikhiqizo enobubanzi obukhulu. Amapayipi ensimbi ejikelezayo asetshenziswa kakhulu ekudluliseni uketshezi olunomfutho ophansi, njengepayipi ezisekelweni zasogwini, izitshalo zikaphethiloli noma izindawo zokuthutha imikhumbi, kanye nezakhiwo zomphakathi kanye nokufaka inqwaba.
Ububanzi bombhobho we-SSAW ngokuvamile bungamasentimitha angu-20 kuya kwangu-100 (406 mm kuya ku-25040 mm).
Indlela yoku-oda amapayipi ensimbi ephrojekthi yakho
Uma u-oda amapayipi ensimbi, kunezindlela ezimbili ezibalulekile: usayizi wepayipi elijwayelekile (i-NPS) kanye nobukhulu bodonga (ishejuli). Kumapayipi angaphansi kwamasentimitha angu-4, ubude bepayipi bungaba yi-single random (SRL) amamitha angu-5-7, noma kumapayipi angaphezu kwamasentimitha angu-4, ubude bepayipi bungaba yi-double random (DRL) amamitha angu-11-13. Ubude obungokwezifiso buyatholakala kumapayipi amade. Iziphetho zamapayipi zingaba yi-bevel (be), i-plane (pe), intambo (THD) kanye ne-coupling (T&C) noma i-groove.
Isifinyezo semininingwane ejwayelekile ye-oda:
Uhlobo (olungenamthungo noma oluhlanganisiwe)
Usayizi wepayipi ojwayelekile
Ishejuli
Uhlobo lokuphela
Ibanga lezinto ezibonakalayo
Ubuningi ngamamitha noma ngamafidi noma ngamathani.
Uma ucabanga ngokuthenga ipayipi elingenamthungo, ipayipi le-ERW, ipayipi le-SSAW noma ipayipi le-LSAW, bheka izinketho i-JINDALAI enazo kuwe bese ucabanga ukuxhumana nethimba lethu ukuze uthole ulwazi olwengeziwe. Sizokunikeza ikhambi elingcono kakhulu lephrojekthi yakho.
Xhumana nathi manje!
