I-API 5Lngokuvamile kubhekisela epayipini lensimbi yepayipi (ipayipi lepayipi) lokusetshenziswa kwepayipi elijwayelekile,ipayipi lensimbikufaka phakathi ipayipi lensimbi elingenamthungo kanye nepayipi lensimbi elihlanganisiwe izigaba ezimbili. Njengamanje empayipini kawoyela sivame ukusebenzisa ipayipi lensimbi elihlanganisiwe uhlobo lwepayipi elihlanganisiwe eliyindilinga elingaphansi komhlaba elihlanganisiwe (I-SSAW), umthungo oqondile ongaphansi kwamanzi ipayipi elihlanganisiwe le-arc (I-LSAW), ipayipi lokushisela lokumelana (I-ERW), ipayipi lensimbi elingenamthungongokuvamile isetshenziswa kububanzi bepayipi bungaphansi kuka-152mm.
Ipayipi lensimbi elijwayelekile likazwelonke le-GB/T 9711-2011 lohlelo lokuthuthwa kwamapayipi embonini kawoyela negesi lihlanganiswe ngokwe-API 5L.
I-GB/T 9711-2011 icacisa izidingo zokukhiqiza zamapayipi ensimbi angenamthungo nahlanganisiwe anezinga ezimbili zokucaciswa komkhiqizo (i-PSL1 ne-PSL2) ezinhlelweni zokuthutha amapayipi embonini kawoyela negesi. Ngakho-ke, indinganiso isebenza kuphela kumapayipi ensimbi angenamthungo namapayipi ensimbi ahlanganisiwe okuthutha uwoyela negesi, futhi ayisebenzi kumapayipi ensimbi ephothiwe.
Amabanga Ensimbi
Amabanga ensimbi ezinto zokusetshenziswa zamapayipi ensimbi ale nqubo ye-API 5L yi-GR.B, X42, X46, X52, X56, X60, X70, X80, njll. Amabanga ensimbi epayipi yensimbi ahlukile, futhi izidingo zezinto zokusetshenziswa kanye nokukhiqizwa nazo zihlukile, kodwa okulingana nekhabhoni phakathi kwamabanga ensimbi ahlukene kulawulwa ngokuqinile.
Izindinganiso zekhwalithi
Ku-API 5L pipe standard, amazinga ekhwalithi (noma izidingo) zepayipi lensimbi ahlukaniswe phakathi kwe-PSL1 kanye ne-PSL2. I-PSL isifinyezo sezinga lokucaciswa komkhiqizo.
I-PSL1 inikeza izinga elijwayelekile lezidingo zekhwalithi yamapayipi; i-PSL2 yengeza izidingo ezidingekayo zokwakheka kwamakhemikhali, ukuqina okunamachashazi, izakhiwo zamandla, kanye nama-NDE engeziwe.
