I-SAWH Comprehensive Guide To Tube: A252 Grade 1 Steel Pipe For Oil And Gas Application
1. Qonda ipayipi le-SAWH:
Amapayipi e-SAWHakhiwe ngamapuleti ensimbi ahlelwe ngokuvunguza.Amashidi akhiwa abe amashubhu futhi ashiselwe kusetshenziswa inqubo ye-arc welding engaphansi kwamanzi.Le ndlela yokushisela iqinisekisa i-weld eqinile, eqhubekayo kulo lonke ubude bepayipi, okwenza imelane kakhulu nezici zokucindezeleka zangaphandle ezifana nomthelela nokucindezela.Lawa mapayipi aziwa ngamandla awo okuthwala imithwalo akhethekile kanye nobuqotho besakhiwo, okuwenza alungele ukuthutha uwoyela negesi.
2. Ipayipi lensimbi le-A252 grade 1:
I-A252 IBANGA 1 iwukucaciswa kwepayipi lensimbi lesakhiwo eliklanyelwe ukusetshenziswa kwengcindezi.Lawa mapayipi akhiwe ngensimbi ye-A252, enezakhiwo ezinhle kakhulu zemishini namandla aqinile.Ipayipi lensimbi i-A252 IBANGA 1 lisetshenziswa kabanzi ekhonweni lalo lokumelana nezingcindezi eziphakeme kanye nokumelana nokugqwala nokonakala ezindaweni ezinokhahlo zikawoyela negesi.

3. Izinzuzo zepayipi lensimbi elingu-A252 grade 1:
a) Amandla Nokuqina:A252 IBANGA LOKU-1 ipayipi lensimbiiqinile futhi ihlala isikhathi eside, ingamelana nemithwalo esindayo futhi ifaneleka kumasistimu okuhambisa uwoyela negesi.Amandla abo aphezulu okuqina aqinisekisa ukuqina kwesikhathi eside futhi anciphisa izidingo zokunakekelwa.
b) Ukumelana nokugqwala: Amapayipi kawoyela negesi athambekele ekugqwaleni ngenxa yezimo ezinzima zemvelo.Ipayipi lensimbi le-A252 GRADE 1 lihlanganisa enye enye into evikela ukugqwala, njenge-fused-bonded epoxy (FBE), ukuthuthukisa ukuqina kwayo nokwelula impilo yayo yesevisi.
c) Ukuvumelana nezimo: Amapayipi e-SAWH angenziwa ngamadayamitha nobude obuhlukahlukene ukuze ahlangabezane nezidingo ezithile zephrojekthi.Lokhu kuvumelana nezimo kusiza ukufakwa ngaphandle kwesidingo samalunga amaningi, kunciphisa ubungozi bokuvuza.
d) Okungabizi kakhulu: Ipayipi lensimbi i-A252 yeBanga loku-1 lihlinzeka ngesixazululo esingabizi kakhulu samapayipi kawoyela negesi.Impilo yabo ende yesevisi kanye nezidingo zokunakekelwa okuphansi zinciphisa izindleko zokusebenza ngokuhamba kwesikhathi.

a.Indlela ye-deoxidation ikhethwe kanje: FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al). b.Inani eliphakeme kakhulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N.Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola. |
4. Ukusetshenziswa kwepayipi lensimbi elingu-A252 grade 1:
Ipayipi lensimbi i-A252 yeBanga loku-1 linohlu olubanzi lwezinhlelo zokusebenza embonini kawoyela negesi, okuhlanganisa:
a) Amapayipi okudlulisa: asetshenziselwa ukuthutha uwoyela ongahluziwe, igesi yemvelo kanye neminye imikhiqizo kaphethiloli esuka emikhakheni yokukhiqiza iye ezikhungweni zokuhluza neyokusabalalisa.
b) I-Offshore Drilling: Amapayipi e-SAWH asetshenziswa emisebenzini yokumba uwoyela nokukhishwa kwegesi phesheya kwezilwandle.Ukumelana nokugqwala kwabo namandla okucindezela okuphezulu kubenza bafaneleke ukuhlola ulwandle olujulile.
c) Ukuhluzwa: Amapayipi ensimbi angu-A252 IBANGA 1 asetshenziswa kakhulu ezindaweni zokuhluza ukuthutha uwoyela ongahluziwe ogayiwe kanye nemikhiqizo kaphethiloli.
Ekuphetheni:
Amapayipi e-SAWH, ikakhulukazi amapayipi ensimbi angu-A252 IBANGA LOKU-1, adlala indima ebalulekileipayipi likawoyela negesiimboni.Amandla azo, ukuqina, nokumelana nokugqwala kuzenza zibe ukukhetha okuthembekile kwezinhlelo zokusebenza ezihlukahlukene.Ukuqonda izinzuzo zamapayipi e-SAWH nezici zawo ezithile kungasiza ekuqinisekiseni ukuthuthwa okuphumelelayo kukawoyela negesi kuyilapho kunciphisa izindleko zokulungisa nokwandisa ukusebenza kahle kwephrojekthi.
