Ukucaciswa okujwayelekile

I-API 5L ngokuvamile isho indinganiso yokusebenzisa yepayipi lomugqa. Ipayipi lomugqa lihlanganisa amapayipi ensimbi angenamthungo namapayipi ensimbi ashiselwe. Njengamanje, izinhlobo zamapayipi ensimbi ashiselwe ngokuvamile asetshenziswa kumapayipi kawoyela ahlanganisa ipayipi elishiselwe i-arc elishiselwe eligobile (i-SSAW), ipayipi elishiselwe i-arc elihlanganisiwe eliqondile (LSAW), kanye nepayipi elishiselwe ukumelana nogesi (ERW). Amapayipi ensimbi angenamthungo ngokuvamile akhethwa lapho ububanzi bepayipi bungaphansi kuka-152mm.

Amapayipi ensimbi ajwayelekile we-GB/T 9711-2011 wezinhlelo zokuthutha zamapayipi emboni kawoyela negesi ahlanganiswa ngokusekelwe ku-API 5L.

I-GB/T 9711-2011 icacisa izidingo zokukhiqiza amapayipi ensimbi angenamthungo namapayipi ensimbi ashiselwe emazingeni amabili okucaciswa komkhiqizo (PSL1 kanye ne-PSL2) asetshenziswa ezinhlelweni zokuthutha zamapayipi ezimboni zikawoyela negesi. Ngakho-ke, leli zinga lisebenza kuphela kumapayipi ensimbi angenamthungo namapayipi ensimbi ashiselwe ukuthutha uwoyela negesi, futhi akusebenzi kumapayipi ensimbi.

Ibanga lensimbi

Amabanga ensimbi eluhlaza weI-API 5Lamapayipi ensimbi afaka i-GR.B,X42, X46, X52, X56, X60, X70, X80, njll. Amabanga ensimbi ahlukene amapayipi ensimbi anezidingo ezihlukene zezinto zokusetshenziswa nokukhiqiza, kodwa okulingana nekhabhoni phakathi kwamabanga ensimbi ahlukene kulawulwa ngokuqinile.

Izinga Lekhwalithi

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

I-PSL1 ihlinzeka ngezimfuneko zezinga lezinga lepayipi lensimbi elijwayelekile; I-PSL2 yengeza izidingo eziyisibopho zokwakheka kwamakhemikhali, ukuqina kwenotshi, izakhiwo zamandla kanye ne-NDE eyengeziwe.

Ibanga lepayipi lensimbi lepayipi lensimbi le-PSL1 (igama elibonisa izinga lamandla epayipi lensimbi, elifana ne-L290, 290 libhekisela emandleni amancane okukhiqiza omzimba wamapayipi angama-290MPa) kanye nebanga lensimbi (noma ibanga, njenge-X42, lapho I-42 imele amandla amancane esivuno noma isiyingi esiphezulu Amandla amancane okukhiqiza wepayipi yensimbi (ku-psi) afana nalawo wepayipi yensimbi Yakhiwe ngezinhlamvu noma inombolo exubile yezinhlamvu nezinombolo ezikhomba izinga lamandla wepayipi lensimbi, futhi ibanga lensimbi lihlobene nokwakheka kwamakhemikhali ensimbi.

Amapayipi ensimbi e-PSL2 akhiwe ngezinhlamvu noma inhlanganisela yezinhlamvu nezinombolo ezisetshenziselwa ukukhomba izinga lamandla lepayipi lensimbi. Igama lensimbi (ibanga lensimbi) lihlobene nokwakheka kwamakhemikhali ensimbi. Kuhlanganisa futhi uhlamvu olulodwa (R, N, Q noma M ) lwakha isijobelelo, esibonisa isimo sokudiliva. Ku-PSL2, ngemva kwesimo sokulethwa, kukhona nohlamvu S (indawo yesevisi ye-asidi) noma u-O (indawo yesevisi yasolwandle) ebonisa isimo sesevisi.

Ukuqhathanisa Okujwayelekile Kwekhwalithi

1. Izinga lekhwalithi le-PSL2 liphezulu kunele-PSL1. Lawa mazinga wokucaciswa amabili awanayo nje kuphela izidingo ezihlukene zokuhlola, kodwa futhi anezidingo ezihlukene zokwakheka kwamakhemikhali kanye nezakhiwo zemishini. Ngakho-ke, lapho u-oda ngokusho kwe-API 5L, imigomo yenkontileka akumele ibonise imininingwane kuphela, amamaki ensimbi, njll. Ngaphezu kwezinkomba ezijwayelekile, izinga lokucaciswa komkhiqizo kufanele liboniswe, okungukuthi, i-PSL1 noma i-PSL2. I-PSL2 iqinile kune-PSL1 mayelana nokwakheka kwamakhemikhali, izakhiwo eziqinile, amandla omthelela, ukuhlola okungabhubhisi nezinye izinkomba.

2. I-PSL1 ayidingi ukusebenza komthelela. Kuwo wonke amamaki ensimbi e-PSL2 ngaphandle kwebanga lensimbi le-X80, usayizi ogcwele ongu-0℃ isilinganiso se-Akv: longitudinal ≥101J, transverse ≥68J.

3. Amapayipi kalayini kufanele ahlolelwe umfutho we-hydraulic ngalinye ngalinye, futhi izinga alisho ukuthi ukushintshwa okungabhubhisi komfutho wamanzi kuvunyelwe. Lona futhi umehluko omkhulu phakathi kwamazinga e-API namazinga aseShayina. I-PSL1 ayidingi ukuhlolwa okungacekeleki phansi, kuyilapho i-PSL2 idinga ukuhlolwa okungonakalisi ngakunye.
