    Ipayipi yensimbi engagqwali yokuhlobisa

    Ipayipi lokuhlobisa lensimbi engagqwali libizwa nangokuthi ipayipi lensimbi engagqwali elishiselwe, elibizwa ngepayipi elishiselwe ngamafuphi.Ngokuvamile, insimbi noma i-steel strip ishiselwa ibe yipayipi lensimbi ngemva kokucwiliswa futhi yenziwe iyunithi kanye nesikhunta.Inqubo yokukhiqiza ipayipi yensimbi eshiselwe ilula, ukusebenza kahle kokukhiqiza kuphezulu, kunezinhlobonhlobo eziningi kanye nokucaciswa, futhi izindleko zemishini zincane, kodwa amandla ajwayelekile aphansi kunepayipi lensimbi engenamthungo.

     

    Kunezinhlobo eziningi zamapayipi ensimbi engagqwali, kodwa asetshenziselwa lezi zinhloso ezilandelayo:

    1,Ukuhlukaniswa kwamapayipi ensimbi engagqwali

    1. Ukuhlelwa ngendlela yokukhiqiza:

    (1) Ipayipi elingenamthungo – ipayipi elidonsa abandayo, ipayipi elikhishwe ngaphandle, ipayipi eligoqiwe elibandayo.

    (2) Ipayipi elishiselwe:

    (a) Ngokwezigaba zenqubo - ipayipi lokushisela elivikelwe igesi, ipayipi lokushisela i-arc, ipayipi lokushisela ukumelana (imvamisa ephezulu, imvamisa ephansi).

    (b) Ihlukaniswe yaba ipayipi elishiselwe eliqondile kanye nepayipi elishiselwe elithandelayo ngokuya ngokushisela.

    2. Ukuhlukaniswa ngokomumo wesigaba: (1) ipayipi lensimbi eliyindilinga;(2) Ishubhu elingunxande.

    3. Ukuhlukaniswa ngokuqina kodonga - ipayipi elincane lensimbi yodonga, ipayipi lensimbi eliwugqinsi

    4. Ihlukaniswa ngokusetshenziswa: (1) Amapayipi omphakathi ahlukaniswe amapayipi ayindilinga, amapayipi angunxande namapayipi ezimbali, asetshenziselwa ukuhlobisa, ukwakha, ukwakheka, njll;

    (2) Ipayipi lezimboni: ipayipi lensimbi lamapayipi asezimbonini, ipayipi lensimbi lamapayipi ajwayelekile (ipayipi lamanzi okuphuza), isakhiwo semishini/ipayipi lokuletha uketshezi, ipayipi lokushintshanisa ukushisa kukabhayela, ipayipi lokuthuthwa kwendle, njll. Ngokuvamile lisetshenziswa emikhakheni eyahlukene yezimboni. , njenge-petrochemical, iphepha, amandla enuzi, ukudla, isiphuzo, imithi kanye nezinye izimboni ezinezidingo eziphezulu ze-fluid medium.

    2,Ipayipi lensimbi elingenamthungo

    Ipayipi lensimbi engenamthungo liwuhlobo lwensimbi ende enengxenye engenalutho futhi awekho amalunga azungezile.

    1. Inqubo yokukhiqiza nokugeleza kwepayipi lensimbi elingenamthungo:

    2. Izici zamapayipi ensimbi ashiselwe:

    Akunzima ukubona kusukela ekugelezeni kwenqubo engenhla: okokuqala, umkhiqizo ukhiqizwa ngokuqhubekayo naku-inthanethi.Ukuqina kodonga, kuyanda ukutshalwa kwezimali kuyunithi namathuluzi wokushisela, futhi ukonga nokusebenziseka kancane.Lapho udonga luba mncane, isilinganiso salo sokufaka-okukhiphayo sizoba siphansi;Okwesibili, inqubo yomkhiqizo inquma izinzuzo zayo kanye nokubi.Ngokuvamile, ipayipi lensimbi elishiselwe linokuqonda okuphezulu, ukujiya kodonga olufanayo, ukukhanya okuphezulu kwangaphakathi nangaphandle kwendawo yamapayipi ensimbi engagqwali (ukukhanya kwendawo yepayipi lensimbi enqunywa ibanga elingaphezulu lepuleti lensimbi), futhi lingalinganiswa ngokungafanele.Ngakho-ke, ihlanganisa umnotho nobuhle bayo ekusetshenzisweni kokunemba okuphezulu, uketshezi lwengcindezi ephakathi nendawo.

     

    Kukhona i-chlorine ion endaweni yokusetshenziswa.Ama-ion e-chlorine atholakala kabanzi, njengosawoti, umjuluko, amanzi olwandle, umoya ohelezayo wasolwandle, inhlabathi, njll. Insimbi engagqwali igqwala ngokushesha lapho kukhona ama-ion e-chloride, yeqa ngisho nensimbi evamile enekhabhoni ephansi.Ngakho-ke, kunezidingo zemvelo yokusetshenziswa kwensimbi engagqwali, futhi kuyadingeka ukuyisula njalo ukuze ususe uthuli futhi uyigcine ihlanzekile futhi yomile.

    316 kanye 317 insimbi engagqwali (bheka ngezansi ukuze uthole izakhiwo 317 stainless steels) kukhona molybdenum equkethe insimbi engagqwali.Okuqukethwe kwe-molybdenum ku-317 insimbi engagqwali kuphakeme kancane kunalokho okusensimbi engagqwali engu-316.Ngenxa ye-molybdenum esensimbi, ukusebenza okuphelele kwale nsimbi kungcono kune-310 ne-304 yensimbi engagqwali.Ngaphansi kwezimo zokushisa eziphakeme, lapho ukuhlushwa kwe-sulfuric acid kungaphansi kuka-15% nangaphezulu kuka-85%, insimbi engagqwali engu-316 inezinhlobonhlobo zokusetshenziswa.I-316 insimbi engagqwali futhi inokumelana nokugqwala okuhle kwe-chloride, ngakho-ke imvamisa isetshenziswa endaweni yasolwandle.Ngokuthuthuka komnotho wezenhlalo, ukusetshenziswa kwepayipi lensimbi engagqwali nakho kuye kwathandwa kakhulu.Izoletha izinguquko ezintsha kuzo zonke izinkambu.
