Isingeniso sepayipi lensimbi le-API 5L

I-API 5Lngokuvamile ibhekisela epayipini lensimbi lensimbi (ipayipi lepayipi) lokuqaliswa kokusebenza kwezinga, ipayipiipayipi lensimbikuhlanganise ipayipi Seamless steel kanye ashiselwe steel ipayipi izigaba ezimbili. Njengamanje epayipini likawoyela sijwayele ukusebenzisa ipayipi lensimbi elishiselwe uhlobo lwepayipi elishiselwe i-arc elingaphansi kwamanzi (I-SSAW), umthungo oqondile wepayipi elishiselwe i-arc (I-LSAW), ipayipi lokushisela ukumelana (ERW), ipayipi lensimbi engenamthungoisetshenziswa ngokuvamile kububanzi bepayipi bungaphansi kuka-152mm.

Ipayipi lensimbi elisezingeni likazwelonke le-GB/T 9711-2011 lohlelo lokuthuthwa kwamapayipi embonini kawoyela negesi lihlanganiswa ngokuya nge-API 5L.

I-GB/T 9711-2011 icacisa izidingo zokukhiqiza zamapayipi ensimbi angenamthungo nashikelwe amazinga amabili okucaciswa komkhiqizo (PSL1 kanye ne-PSL2) kumasistimu okuthutha amapayipi embonini kawoyela negesi. Ngakho-ke, izinga lisebenza kuphela kumapayipi ensimbi angenamthungo namapayipi ensimbi ashiselwe ukuthutha uwoyela negesi, futhi akusebenzi kumapayipi ensimbi.

Amabanga Ensimbi

Izigaba zensimbi zezinto zokusetshenziswa zamapayipi ensimbi aleli zinga le-API 5L yi-GR.B, X42, X46, X52, X56, X60, X70, X80, njll. Amabanga ensimbi wamapayipi ensimbi ahlukile, kanye nezidingo zezinto ezingavuthiwe. futhi ukukhiqizwa nakho kuhlukile, kodwa okulingana nekhabhoni phakathi kwamamaki ensimbi ahlukene alawulwa ngokuqinile.

 

Izindinganiso zekhwalithi

Esilinganisweni sepayipi le-API 5L, izindinganiso zekhwalithi (noma izidingo) zepayipi lensimbi zihlukaniswa zibe i-PSL1 ne-PSL2. I-PSL isifinyezo sezinga lokucaciswa komkhiqizo.

I-PSL1 ihlinzeka ngezinga elijwayelekile lezidingo zekhwalithi yamapayipi; I-PSL2 yengeza izidingo eziyisibopho zokwakheka kwamakhemikhali, ukuqina okunophawu, izici zamandla, nama-NDE engeziwe.
