- I. Ukufakwa Okubalulekile: Ukulawula Imininingwane Ebalulekile Kuzinhlelo Ezingaphansi
1. Ukufakwa Komzimba Oyinhloko: Qinisekisa Ukuzinza kanye Nokulayisha Okufanayo
Ukulinganisa: Sebenzisa izinga lomoya ukuze uhlole isisekelo sesithando somlilo ukuze uqinisekise ukuthi ukuchezuka okuqondile nokuvundlile kungu-≤1‰. Lokhu kuvimbela ukutsheka okungase kubangele umthwalo ongalingani kumashubhu esithandweni kanye nokugeleza okungekuhle kukawoyela oshisayo.
Indlela Yokuvikela: Sebenzisa amabhawodi okusetshenzwa kulengwa kuwo (imininingwane yebhawodi kumele ihambisane nebhukwana lemishini). Qinisa ngokulinganayo ukuvimbela ukuguqulwa kwesisekelo. Okokusebenza okugibele i-skid, qinisekisa ukuthi i-skid inamathele ngokuqinile phansi futhi ayinyakazi.
Ukuhlola Izinsiza: Ngaphambi kokufaka, linganisa i-valve yokuphepha (ingcindezi yokusetha ihlangabezana nezidingo zokuklama, njengezikhathi ezingu-1.05 zokucindezela kokusebenza) kanye negeji yokucindezela (ububanzi obuyi-1.5-3 izikhathi zokucindezela kokusebenza, ukunemba ≥1.6), futhi ubonise ilebula eqinisekisiwe. Ama-thermometers kufanele afakwe ku-oyili oshisayo kanye namapayipi okukhipha ukuze kuqinisekiswe ukuqapha okunembile.
2. Ukufakwa Kwesistimu Yepayipi: Vimbela Ukuvuza, Ukuvinjelwa Kwegesi, kanye Ne-Coking
Material kanye Welding:Amapayipi amafutha ashisayokumele yakhiwe ngepayipi lensimbi elingenamthungo elingamelana nezinga lokushisa eliphezulu (njengensimbi engu-20# noma i-12Cr1MoV). Amapayipi ama-galvanized avunyelwe (ungqimba lwe-zinc luphuka kalula emazingeni okushisa aphezulu, okuholela ekuphekeni). Ukushisela kufanele kwenziwe kusetshenziswa i-argon arc welding yesisekelo kanye ne-arc welding yekhava. Amajoyinti okushisela kufanele ahlolwe nge-radiographic (RT) okungu-100% ngezinga lokuphasa elingu-≥ II ukuvimbela ukuvuza.
Isakhiwo Sepayipi:
I-Pipeline Slope: Theipayipi lokubuyisela uwoyela oshisayokumele ibe nomthambeka ongu-≥ 3‰, owehlela ethangini likawoyela noma indawo yokukhipha uwoyela ukuze kuvinjelwe ukunqwabelana kwamafutha endaweni kanye nokuphekwa. Umthambeka wepayipi lokukhipha uwoyela ungancishiswa ube ≥ 1‰ ukuze kuqinisekiswe ukugeleza kukawoyela okushelelayo.
I-Exhaust kanye ne-Draining: Faka ivalvu yokukhipha umoya endaweni ephakeme kakhulu yepayipi (njengenhla kwesithando somlilo noma ejikeni) ukuze uvimbele ukunqwabelana kwegesi ohlelweni, okungabangela "ukuvinjwa kwegesi" (ukushisa okweqile kwasendaweni). Faka i-valve yokukhipha amanzi endaweni ephansi kakhulu ukuze kube lula ukuhlanzwa okuvamile kokungcola nokupheka. Gwema ukugoba okubukhali nezinguquko zobubanzi: Sebenzisa ukugoba okugobile (i-radius of curvature ≥ izikhathi ezi-3 ubukhulu bepayipi) ekujikeni kwamapayipi; gwema ukugoba kwe-engeli yesokudla. Sebenzisa izinciphisi ezigxilile lapho ushintsha amadayimitha ukuze ugweme izinguquko ezingase ziphazamise ukuhamba kukawoyela futhi zibangele ukushisa okweqile kwendawo.
Ukuhlolwa kokuvala uphawu: Ngemuva kokufakwa kwepayipi, yenza ukuhlolwa kokucindezela kwamanzi (ingcindezi yokuhlola izikhathi ezingu-1.5 ingcindezi yokusebenza, gcina ingcindezi imizuzu engu-30, akukho ukuvuza) noma ukuhlolwa kwengcindezi ye-pneumatic (ingcindezi yokuhlola izikhathi ezingu-1.15 ingcindezi yokusebenza, gcina ingcindezi amahora angu-24, ingcindezi yehla ≤ 1%). Ngemuva kokuqinisekisa ukuthi akukho ukuvuza, qhubeka ne-insulation.
I-insulation: Amapayipi kanye nemizimba yezithando zomlilo kufanele ifakwe insulation (kusetshenziswa izinto zokugqumisa ezimelana nezinga lokushisa eliphezulu njengoboya bedwala ne-aluminium silicate, enogqinsi olungu-≥ 50mm). Mboza ngongqimba oluvikelayo lwensimbi ukuze uvimbele ukulahlekelwa ukushisa nokusha. I-insulation layer kufanele ivalwe ngokuqinile ukuze kuvinjwe amanzi emvula ukuthi angangeni futhi abangele ukwehluleka kokushisa. 3. Ukufakwa Kwesistimu Kagesi: Ukulawula Ukuphepha Nokunemba
Imininingwane Yezintambo: Ikhabhinethi kagesi kufanele ibe kude nemithombo yokushisa neyomthombo wamanzi. Izintambo zamandla nokulawula kufanele zibekwe ngokuhlukana (sebenzisa ikhebula elivimba amalangabi kumakhebuli kagesi). Amatheminali kufanele aboshwe ngokuvikelekile ukuze kuvinjelwe ukuxhumana okuxekethile okungaholela ekushiseni ngokweqile. Uhlelo lokubeka phansi kufanele luthembeke, ngokumelana komhlabathi okungu-≤4Ω (kuhlanganise nokubeka phansi kwemishini ngokwayo kanye nekhabhinethi kagesi).
Izidingo Zobufakazi Bokuqhuma: Okokushiswa uwoyela/okushiswa ngegesiama-boilers wamafutha ashisayo,izingxenye zikagesi eduze kwesishisi (njengamafeni namavalvu e-solenoid) kufanele zikwazi ukuqhuma (isb., Ex dⅡBT4) ukuze kuvinjelwe izinhlansi ukuthi zingabangeli ukuqhuma kwegesi.
Ukuhlola Ukunengqondo Kokulawula: Ngaphambi kokusebenza, qinisekisa izinhlelo zikagesi ukuze uqinisekise ukuthi ukulawulwa kwezinga lokushisa, ukuvikelwa kokucindezela, nama-alamu eleveli yoketshezi ephezulu naphansi asebenza kahle (isb., ukucisha okuzenzakalelayo kukawoyela oshisayo uma izinga lokushisa liphezulu kanye nokuqaliswa kokushisa kunqatshelwe uma ileveli yoketshezi iphansi).
II. Ukugunyazwa Kwesistimu: Qinisekisa Ukuphepha Ngezigaba
1. I-Cold Commissioning (Akukho Ukushisisa)
Hlola Ukuqina Kwepayipi: Gcwalisa uhlelo ngamafutha ashisayo (vula i-valve yokukhipha ukukhipha wonke umoya ngesikhathi sokugcwalisa) kuze kube yilapho izinga likawoyela lifinyelela ku-1 / 2-2 / 3 ye-tank. Yiyeke ihlale amahora angu-24 bese uhlola amapayipi namashisela ukuthi akavuzi yini.
Hlola Uhlelo Lokuzungeza: Qala iphampu futhi uhlole izinga lokusebenza lamanje nomsindo (inani elilinganiselwe ≤ lamanje, umsindo ≤ 85dB). Qinisekisa ukuthi uwoyela oshisayo uzungeza kahle ngaphakathi kwesistimu (thinta amapayipi ukuze uqinisekise ukuthi awekho amabala abandayo ukugwema ukuvaleka komoya).
Qinisekisa Imisebenzi Yokulawula: Lingisa amaphutha afana nokushisa ngokweqile, ukucindezela ngokweqile, nezinga eliphansi loketshezi ukuze uqinisekise ukuthi ama-alamu nemisebenzi yokuvalwa kwesimo esiphuthumayo isebenza kahle.
2. Ukukhishwa Kwamafutha Ashisayo (Ukwenyuka Kwezinga Lokushisa Kancane)
Ukulawula Izinga Lokushisa: Ukwenyuka kwezinga lokushisa kokuqala kufanele kuhambe kancane ukuze kugwenywe ukushisa okweqile kwendawo kanye nokupheka uwoyela oshisayo. Izimfuneko ezithile:
Ukushisa kwekamelo kuya ku-100 ° C: Izinga lokushisa ≤ 20 ° C / h (ukususa umswakama emafutheni ashisayo);
I-100 ° C kuya ku-200 ° C: Izinga lokushisa ≤ 10 ° C / h (ukususa izingxenye zokukhanya);
I-200 ° C kuya ekushiseni okusebenzayo: Izinga lokushisa ≤ 5 ° C / h (ukuzinzisa uhlelo).
Ukuqapha Inqubo: Phakathi nenqubo yokushisisa, qapha eduze igeji yokucindezela (ngokungaguquguquki noma ukwanda okungazelelwe) kanye nethermometer (ngamazinga okushisa afanayo kuwo wonke amaphuzu). Uma kutholakala noma yikuphi ukudlidliza kwamapayipi noma izinga lokushisa elingavamile (isb., ukushisa okweqile kwendawo okungaphezu kuka-10°C) kutholwa, vala masinyane isithando somlilo ukuze sihlolwe ukuze kuqedwe noma yikuphi ukuvaleka komoya noma ukuvimba.
I-Nitrogen Gas Protection (Okokuzithandela): Uma uwoyela oshisayo usetshenziswa ekushiseni ≥ 300 ° C, kunconywa ukwethula i-nitrogen (ukucindezela okuncane okuhle, 0.02-0.05 MPa) ku-tank yamafutha ukuvimbela i-oxidation ukuthi ingathintani nomoya futhi yandise impilo yayo yesevisi.
Uma ufuna ukwazi okwengeziwe ngomkhiqizo wethu, sicelaXhumana nathi!
