Ipayipi lensimbi le-API 5L X42, eyaziwa nangokuthi i-L290, iqanjwe ngamandla ayo amancane okukhiqiza angu-42,100 psi (290 MPa).I-X42 inamandla amancane okudonsa angu-60,200 psi (415 MPa).
Ipayipi lensimbi ye-X42/L290 ingeyebanga eliphansi futhi isetshenziselwa ikakhulukazi izinhlelo zokusebenza ezinengcindezi ephansi.Okufana nokudluliswa kwegesi yedolobha, izinhlelo zokuhambisa amanzi, nezinye izinhlelo zamapayipi ezingadingi umthamo wokuthwala ingcindezi ephezulu.
Amazinga
Ngokuya ngezidingo zokusebenza, amashubhu e-X42 ahlukaniswe ngamaleveli amabili wokucaciswa komkhiqizo,I-PSL1 ne-PSL2.
I-PSL1ukucaciswa kwepayipi lomugqa webanga eliyisisekelo.Ngokuvamile isetshenziswa ezinhlelweni zokuthutha ezijwayelekile lapho izimo zemvelo zingeqisi kakhulu.
I-PSL2iyibanga elithuthuke kakhulu.Idizayinelwe izimo ezidinga kakhulu, njengendawo enengcindezi ephezulu, kanye nezinhlelo zokusebenza eziyinkimbinkimbi noma ezonakalisayo.
Ukukhetha ukuthi yiliphi ibanga lepayipi lensimbi elizosetshenziswa lincike ezidingweni ezithile zephrojekthi, kufaka phakathi indawo yesevisi ehlosiwe kanye nezidingo zokuqina.
Inqubo Yokukhiqiza Ipayipi Lensimbi
Ukukhiqizwa kwamashubhu ensimbi e-X42 kuhlanganisa izinhlobonhlobo zamasu okukhiqiza ukuze kuhlangatshezwane nezidingo ezahlukene zobunjiniyela nezemvelo.Ukusuka okungenamthungo kuya ezinhlotsheni ezahlukahlukene zamasu wokushisela, indlela ngayinye inikeza izinzuzo zayo eziyingqayizivele nezindawo zokusebenzisa.

I-API 5L X42 PSL1 Chemical Composition
Izidingo zokwakheka kwamakhemikhali ze-PSL1 zikhululekile uma kuqhathaniswa, ngenhloso yokuqinisekisa ukushisela kanye nokuqina kwempahla.
I-API 5L X42 PSL2 Chemical Composition
I-PSL2 inokulawula okuqinile kokwakheka kwamakhemikhali ukuze kuqinisekiswe ikhwalithi ephezulu nokusebenza kwezindawo ezifunwa kakhulu nezinhlelo zokusebenza.
Amabanga athile eshubhu ye-PSL2 aklanyelwe ngokukhethekile izinhlelo zokusebenza ezikhethekile, okufaka phakathi izijobelelo ezibalulekile "S" kanye no-"O".Isijobelelo esithi "S" sibonisa ukuthi ipayipi lakhelwe izindawo ezimuncu, kanti amapayipi anesejobelelo esithi "O" adizayinelwe izindawo zeplathifomu ezingasogwini lolwandle.
Ngenxa yokuthi lezi zindawo ziyagqwala ikakhulukazi, ukumelana nokugqwala kwepayipi lensimbi kuthuthukiswa ngokushintsha ukwakheka kwamakhemikhali.
