Kuyipayipi lensimbi elingenamthungo okufanele lihlangabezane nezidingo zezakhiwo zamakhemikhali nemishini yeBanga B le-API 5L, i-ASTM A106, ne-ASTM A53 ngesikhathi esifanayo.
Lolu hlobo lwepayipi lungasetshenziswa ngokuguquguqukayo kumaphrojekthi ahlukene ngaphandle kokukhathazeka ngezinkinga zokuhambisana okujwayelekile.Iphinde yenze lula ukuphathwa kwempahla ngokunciphisa isidingo sokuthenga amashubhu amazinga amaningi ahlukene.
Qaphela: Kubalulekile ukuqaphela ukuthi i-API 5L GR.B lapha ibhekisela ku-API 5L PSL1 grade B.
Insimbi ye-Botopingumkhiqizi ohamba phambili wamapayipi ensimbi kanye nesitoko e-China, onguchwepheshe ekukhiqizeni nasekunikezeni ipayipi lensimbi elingenamthungo le-carbon steel for liquid and oil application.Kusukela sasungulwa ngo-2014, imikhiqizo yethu ithunyelwe emazweni amaningi nasezifundeni ezifana ne-Australia, Canada, India, Saudi Arabia, njalonjalo, futhi siqongelele ulwazi olucebile kwezohwebo lwamazwe ngamazwe.
Senza amapayipi ensimbi ngokuhambisana ngokuqinile nezindinganiso zamazwe ngamazwe njenge-API 5L, ASTM A106, ne-ASTM A53 ukuze siqinisekise imikhiqizo esezingeni eliphezulu nesezingeni.Uhlu lomkhiqizo luhlanganisa amapayipi ensimbi angenamthungo anamadayamitha angaphandle asuka ku-10.3 - 660 mm nogqinsi olusuka ku-2 - 100 mm.
Ngamathani angaphezu kuka-8,000 amapayipi ensimbi angenamthungo esitokweni, siyakwazi ukuqinisekisa ukulethwa okusheshayo kosayizi abajwayelekile.Ngezinhlobo ezikhethekile nosayizi, siphinde sinikeze ngezinsizakalo zokukhiqiza ezingokwezifiso ukuze sihlangabezane nezidingo ezithile zamakhasimende.
Amashubhu ensimbi angenamthungoakhiqizwa ngezinqubo ezimbili eziyinhloko: ukuqedela okushisayo nokudweba okubandayo.
I-DN ≤ 40 ingenza ukushisa kuphele noma kubanda kudonswe, ikakhulukazi kubanda.
I-DN ≥ 50 izobe isiphelile.Amashubhu ensimbi adonswa ngokubanda angenamthungo nawo ayatholakala uma uwacela.
| Ububanzi Okuzisholo | I-DN 6- 650 [NPS 1/8 - 26] |
| I-Diameter Yangaphandle Ecacisiwe | 10.3 - 660 mm [0.405 - 26 in.] |
| Ikilasi lesisindo | I-STD (Ejwayelekile), i-XS (Inamandla Kakhudlwana), XXS (I-Double Extra Strong) |
| Ishejuli No. | Isheduli 10, iSheduli 20, iSheduli 30, iSheduli 40, iSheduli 60, iSheduli 80, iSheduli 100, iSheduli 120, 140, 160, |
Ukuze kuqinisekiswe ukuthi ipayipi lihlangabezana nezidingo zokwakheka kwamakhemikhali zeBanga B zawo wonke amazinga amathathu, i-API 5L, i-ASTM A106, ne-ASTM A53, ukwakheka kwamakhemikhali kokokusebenza kufanele kulawulwe ngokuqinile phakathi nenqubo yokukhiqiza.Okulandelayo yizidingo eziqondile zokwakheka kwamakhemikhali kulawa mazinga amathathu:
I-API 5L Ibanga B I-Chemical Composition
I-ASTM A106 Ibanga B Ukubunjwa Kwamakhemikhali
I-ASTM A53 Ibanga B Ukubunjwa Kwamakhemikhali
| Hlola | I-API 5L PSL1 Ibanga B | I-ASTM A106 Ibanga B | I-ASTM A53 Ibanga B | |
| Amandla okukhiqiza, imiz | MPa [psi] | 245 [35,500] | 240 [35,000] | 240 [35,000] |
| Amandla aqinile, imiz | MPa [psi] | 415 [60,200] | 415 [60,000] | 415 [60,000] |
Ukuqhathaniswa kwezidingo zemishini zeBanga B ku-API 5L, i-ASTM A106, ne-ASTM A53 kukhombisa ukuthi zinezidingo ezifanayo zokuqina namandla esivuno.Lokhu kuvumelana kuyisisekelo sokushintshwa kwalezi zindinganiso futhi kuqinisekisa ukuthi imikhiqizo ye-tubular ingasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ngaphandle kokukhathazeka ngezakhiwo ezingafani.
Ukuhlolwa Kwezakhiwo Zemishini
Ukuhlolwa Kwezakhiwo Zemishini
Ngaphezu kokuhlinzeka ngamashubhu ensimbi angenamthungo aphezulu,Insimbi ye-Botopinikeza izinsiza eziningi zokumboza indawo ukuze kuhlangatshezwane nezidingo ezahlukene zokuvikela ukugqwala kanye nezimo zemvelo.
Izindwangu zamapayipi ensimbi ngokuvamile zihlukaniswa zibe ukuvikela kwesikhashana kanye nokuvimbela ukugqwala kwesikhathi eside.Sivame ukubona ipayipi lensimbi engenamthungo elimbozwe ngengubo emnyama, esetshenziselwa ukunikeza isivikelo sesikhashana ukuze kuncishiswe ukugqwala ngesikhathi sokuthutha olwandle nokugcinwa kwepayipi.
Izinhlobo ezivamile zezingubo zokuvikela ukugqwala zihlanganisaupende, idiphu elishisayo livuza, I-3LPE, I-FBE, nabanye.Ukukhetha ukugqoka okulungile akusizi nje ukwandisa impilo yesevisi yepayipi yensimbi kodwa futhi kunciphisa ngokuphumelelayo izindleko zokusebenza jikelele.
I-API 5L, ASTM A106, kanye ne-ASTM A53 yeBanga B ipayipi lensimbi elingenamthungo livame ukusetshenziswa ezinhlelweni zamapayipi okuthutha isitimu, amanzi, igesi, nomoya.Lawa mashubhu abuye alungele ukwenza ukugoba, ama-flange, nokunye ukwenza imisebenzi.
I-Botop Steel ibilokhu igcizelela ikhwalithi njengempande yebhizinisi, esikholelwa ukuthi iwukhiye wokuwina ukwethenjwa kwamakhasimende nokuqashelwa kwemakethe.Emsebenzini wesikhathi eside wemboni, siqongelele ulwazi olucebile kanye namacala amaningi ayimpumelelo.
