Izinga lepayipi lensimbi engenamthungo le-API 5L liwuphawu olwakhiwe yi-American Petroleum Institute (API) futhi lisetshenziswa kakhulu ezinhlelweni zamapayipi embonini kawoyela negesi. Amapayipi ensimbi angenamthungo e-API 5L asetshenziswa kakhulu ekuthuthweni kukawoyela, igesi yemvelo, amanzi nolunye uketshezi ngenxa yamandla awo amangalisayo nokumelana nokugqwala. Okulandelayo isingeniso sezinto ezihlukahlukene ze-API 5L ejwayelekile kanye nebanga lesicelo sabo, inqubo yokukhiqiza nokuhlolwa kwefekthri.

Okubalulekile
I-API 5L Gr.B, API 5L Gr.B X42, API 5L Gr.B X52, API 5L Gr.B X60, API 5L Gr.B X65, API 5L Gr.B X70

Inqubo yokukhiqiza
Inqubo yokukhiqiza ye-API 5L ipayipi lensimbi engenamthungo ihlanganisa lezi zinyathelo ezilandelayo:

Ukukhetha impahla eluhlaza: Khetha amabhilidi ensimbi ekhwalithi ephezulu, ngokuvamile insimbi ye-carbon steel noma i-low-alloy steel.
Ukushisisa nokubhoboza: I-billet ishiselwa ezingeni lokushisa elifanele bese i-tube billet engenalutho ikhiqizwa ngomshini wokubhoboza.
Ukuginqika okushisayo: I-billet yeshubhu engenalutho iphinde icutshungulwe kumshini wokugaya oshisayo ukuze yakhe ububanzi bepayipi elidingekayo kanye nokuqina kodonga.
Ukwelashwa kokushisa: Ukwenza kube kuvamile noma ukucisha kanye nokuthambisa ipayipi lensimbi ukuze kuthuthukiswe ukusebenza kwalo.
Umdwebo obandayo noma ukugoqa okubandayo: Umdwebo obandayo noma ukugoqa okubandayo kwenziwa njengoba kudingekile ukuze kuzuzwe ukunemba okuphezulu kwe-dimensional kanye nekhwalithi ephezulu.
Ukuhlolwa kwefekthri
Amapayipi ensimbi angenamthungo e-API 5L kufanele ahlolwe ngokuqinile ngaphambi kokushiya imboni ukuze kuqinisekiswe ukuthi ahlangabezana nezidingo ezijwayelekile:

Ukuhlaziywa kokwakheka kwamakhemikhali: Thola ukwakheka kwamakhemikhali kwepayipi lensimbi ukuze uqinisekise ukuthi lihlangabezana nezindinganiso ezishiwo.
Ukuhlolwa kwempahla yemishini: Kufaka amandla aqinile, amandla esivuno kanye nokuhlolwa kobude.
Ukuhlola okungalimazi: Sebenzisa ukutholwa kwamaphutha kwe-ultrasonic kanye nokuhlolwa kwe-X-ray ukuze uhlole ukonakala kwangaphakathi kwepayipi lensimbi.
Ukutholwa kobukhulu: Qinisekisa ukuthi ububanzi bangaphandle, ukujiya kodonga nobude bepayipi lensimbi kuhlangabezana nezidingo.
Ukuhlolwa kwe-Hydrostatic: Yenza ukuhlolwa kwe-hydrostatic epayipini lensimbi ukuze uqinisekise ukuphepha nokwethembeka kwalo ngaphansi kwengcindezi yokusebenza.
Isifinyezo
Amapayipi ensimbi angenamthungo e-API 5L asetshenziswa kakhulu emkhakheni wokuthuthwa kukawoyela negesi ngenxa yamandla awo aphezulu, ukumelana nokugqwala kanye nezakhiwo ezinhle zemishini. Amapayipi ensimbi e-API 5L amamaki ahlukene ezinto ezibonakalayo afanele izingcindezi ezihlukene nezimo zemvelo, ahlangabezana nezidingo zezimo ezihlukahlukene zokusebenza eziyinkimbinkimbi. Izinqubo zokukhiqiza eziqinile kanye nokuhlolwa kwefekthri kuqinisekisa ikhwalithi nokusebenza kwamapayipi ensimbi, okunikeza isiqinisekiso sesistimu yokuthutha ephephile futhi ephumelelayo.
