Emkhakheni wezinhlelo zikawoyela negesi, amapayipi ensimbi angenamthungo adlala indima ebalulekile.Njengepayipi lensimbi elinembayo eliphezulu, elinamandla amakhulu, lingakwazi ukumelana nezindawo ezinokhahlo ezihlukahlukene njengokucindezela okuphezulu, izinga lokushisa eliphezulu, ukugqwala, njll., ngakho-ke lisetshenziswa kabanzi kumapayipi okuthutha kanye nemikhumbi yokucindezela emikhakheni yamandla amasha njengamafutha kanye igesi yemvelo.
1. Izici
Amapayipi ensimbi angenamthungo asetshenziswa endaweni kawoyela negesi anezici ezilandelayo:
1. Ukunemba okuphezulu: Ipayipi yensimbi engenamthungo inodonga olufanayo nokunemba okuphezulu, okungaqinisekisa ukushelela nokuvala ipayipi.
2. Amandla aphezulu: Njengoba amapayipi ensimbi angenamthungo engenawo ama-welds, anamandla aphakeme nokuqina futhi angakwazi ukumelana nezindawo ezinokhahlo njengokucindezela okuphezulu kanye nezinga lokushisa eliphezulu.
3. Ukumelana nokugqwala: Izingxenye ze-asidi ne-alkali kuwoyela negesi yemvelo zizobangela ukugqwala kwamapayipi ensimbi, kodwa isisekelo esisetshenziswa kumapayipi ensimbi angenamthungo siphezulu, ngakho sinokumelana nokugqwala okungcono futhi kungaqinisekisa ukusebenza kahle kwepayipi.
4. Impilo ende: Ngenxa yenqubo eqinile yokukhiqiza yamapayipi ensimbi angenamthungo, impilo yawo yesevisi ingaqinisekiswa ukuthi izohlala amashumi eminyaka, ngaleyo ndlela kuncishiswe imvamisa yokushintshwa nezindleko ezihambisanayo.
2. Inqubo yokukhiqiza
Inqubo yokukhiqiza amapayipi ensimbi angenamthungo endaweni kawoyela negesi ikakhulukazi ihlanganisa lezi zinyathelo ezilandelayo:
1. Ukuncibilika: Faka insimbi encibilikisiwe esithandweni ukuze incibilikiswe ukuze kukhishwe ukungcola namagesi ukuze uqinisekise ubumsulwa bepayipi lensimbi.
2. Ukubunjwa okuqhubekayo: Insimbi encibilikisiwe ithululelwa emshinini wokuphonsa oqhubekayo ukuze iqine ukuze yakhe i-billet yensimbi.
3. Ukugingqika: I-billet yensimbi ingaphansi kwezinqubo eziningi zokugingqa ukuze ikhubaze futhi yakhe isakhiwo se-tubular esidingekayo.
4. Ukubhoboza: Ipayipi lensimbi eligoqiwe libhobozwa ngomshini wokubhoboza ukuze lenze udonga lwepayipi lensimbi engenamthungo.
5. Ukwelashwa kokushisa: Ukwelashwa kokushisa kwenziwa epayipini lensimbi engenamthungo elinezimbobo ukuze kuqedwe ukucindezeleka kwangaphakathi futhi kuthuthukiswe izici zayo zemishini.
6. Ukuqeda: Ukuqedwa kobuso kanye nokucutshungulwa kwe-dimensional kwamapayipi ensimbi engenamthungo afakwe ukushisa ukuze kuhlangatshezwane nezidingo zamakhasimende.
7. Ukuhlola: Ukuhlolwa okuqinile kwenziwa kumapayipi ensimbi angenamthungo aqediwe, okuhlanganisa ukunemba kobukhulu, ukufana kodonga, ikhwalithi yangaphakathi nengaphandle, njll., ukuqinisekisa ikhwalithi yomkhiqizo.
Ngamafuphi, amapayipi ensimbi angenamthungo asetshenziswa ensimini kawoyela negesi, njengempahla yepayipi yensimbi enembayo ephezulu, enamandla amakhulu, adlala indima ebalulekile kumapayipi okudlulisela kanye nemikhumbi yokucindezela emkhakheni wamandla.
Imikhiqizo esemqoka yenkampani yethu embonini ye-petroleum yile:

I-API 5Linsimbi yepayipi, amamaki ensimbi afaka i-GR.B, X42, X46, 52, X56, X60, X65,
Imingcele yomkhiqizo
Ipayipi lensimbi le-API 5L likawoyela:

(6) Ukupakisha: isifutho sokupenda, i-beveling, izikepisi zamapayipi, ibhande lensimbi, izintambo zokuphakamisa eziphuzi, kanye nokupakishwa kwezikhwama ezilukiwe.
(7) API 5LGR.B ipayipi lensimbi engenamthungo ipayipi.
I-API 5CTisikhwama sikawoyela sisetshenziselwa kakhulu ukuthutha uketshezi namagesi afana nowoyela, igesi yemvelo, igesi yamalahle, amanzi, njll. i-api5ct oil casing ingahlukaniswa ibe izici ezintathu: R-1, R-2 kanye R-3 ngokobude obuhlukene.Izinto eziyinhloko B, X42, X46, X56, X65, X70, njll.
