Izizathu zokuthi kungani amalunga okwandisa insimbi asetshenziswa kabanzi

Ijoyinti lokunwetshwa kwensimbi liyisinxephezelo esifakwe ngokuqondile epayipini lesigaba esisodwa noma uketshezi lwe-multiphase.Ikakhulukazi yakhiwe ngomkhono (ipayipi eliwumgogodla), igobolondo, okokuvala, njll. imbobo yokuvala ngokuvamile ivalwa nge-graphite impahla enezinga eliphezulu lokushisa, enezinzuzo, ukuthambisa, ukuvala izinga lokushisa eliphezulu, njll. esetshenziselwa ukunxephezela ukunwetshwa kwe-axial nokufinyela kwepayipi kanye nesinxephezelo se-axial kunoma iyiphi i-engeli.Amalunga okwandisa insimbi anezici zomthamo omncane kanye nesinxephezelo esikhulu.Isetshenziswa kabanzi kumapayipi okuthutha ekwakhiweni kwemikhumbi, ukushisisa amadolobha, i-metallurgy, izimayini, ukukhiqiza amandla kagesi, i-petroleum, imboni yamakhemikhali, ukwakhiwa nezinye izimboni.

Umkhono ongaphakathi wohlobo olusha lwejoyinti lokunweba lensimbi uxhunywe nepayipi, futhi wamukela isimiso nesakhiwo sokuzivala ngomfutho wegazi ozimele.Ingakwazi ukuslayida ngokukhululekile kugobolondo ngokunwetshwa nokufinyezwa kwepayipi, futhi ingahlangabezana nezimfuneko zokuvala zanoma yiliphi ipayipi.Izinto ezintsha zokwenziwa zisetshenziswa phakathi kwegobolondo nomkhono wangaphakathi ukuze kuvalwe, okungamelana nezinga lokushisa eliphezulu, kuvimbele ukugqwala nokumelana nokuguga.Izinga lokushisa elisebenzayo lingu-40 ℃ kuya ku-400 ℃, elingakwazi nje ukunquma i-axial sliding, kodwa futhi liqinisekise ukuthi i-medium epayipini ayivuzi.Ijoyinti entsha yokwandisa insimbi iklanywe ngethuluzi elivimbela ukuphulwa, elingaqinisekisa ukuthi ngeke likhishwe uma linwebeka endaweni elinganiselwe, ukuze kuthuthukiswe ukuzinza kwayo yonke inethiwekhi yamapayipi.Ijoyinti entsha yokwandisa insimbi ayinazo izidingo zokuqukethwe kwe-ion ye-chloride, futhi ifaneleka ngokukhethekile amasistimu anama-ion e-chloride eqile phakathi nendawo noma endaweni ezungezile.

Inhlanganisela yensimbi yokwandisa iyasebenza kungcindezi yobunjiniyela obuphakathi ≤ 2.5MPa, izinga lokushisa eliphakathi -40 ℃ ~ 600 ℃.Isinxephezelo semikhono sithatha indandatho entsha yokuvala eguquguqukayo yegraphite, enezici zamandla aphezulu, i-coefficient ephansi yokungqubuzana (0.04~0.10), akukho ukuguga, umphumela omuhle, ukunakekelwa okufanele, njll. impilo yesevisi yejoyinti lokunwetshwa kwensimbi inkulu. , nempilo yokukhathala ilingana neyepayipi.Ngemuva kokwelashwa okukhethekile, indawo eshelelayo inokusebenza okuhle kokugqwala emanzini anosawoti, isixazululo sikasawoti kanye nezinye izindawo, ephakeme izikhathi ezingaphezu kuka-50 kune-austenitic stainless steel.

Izizathu zokuthi kungani amalunga okunwetshwa kwensimbi asetshenziswa kabanzi:

1. Impilo yesevisi yamajoyinti okunwetshwa kwensimbi yinde, futhi impilo yokukhathala ilingana neyamapayipi.Ngemva kokwelashwa okukhethekile, indawo eshelelayo akulula ukugqwala emanzini anosawoti, isixazululo sikasawoti kanye nezinye izindawo, futhi ukusebenza kwayo kungcono kunokwensimbi engagqwali ye-austenitic izikhathi ezingaphezu kuka-50.Ngesikhathi esifanayo, lapho umphumela wokuvala uphawu ubuthakathaka ngenxa yokugqoka eminyakeni embalwa kamuva, i-flange ingaqiniswa futhi ukuze kuthuthukiswe ukusebenza kokuvala, noma ama-bolt angathukululwa, indandatho yokucindezela ingasuswa, bese eyodwa noma ezimbili. izingqimba zamasongo okuvalwa zingafakwa ukuze zicindezele indandatho yokucindezela futhi ziqhubeke nokusetshenziswa.

2. Isinxephezelo semikhono asinazo izidingo zokuqukethwe kwe-ion ye-chloride, futhi sifaneleka ngokukhethekile amasistimu anama-ion e-chloride eqile phakathi nendawo noma endaweni ezungezile.

3. Isinxephezelo semikhono sihlukaniswe saba yindlela eyodwa yesinxephezelo nesakhiwo sesinxephezelo sezindlela ezimbili.Isakhiwo sesinxephezelo esinezinhlangothi ezimbili sibonakala ngokuthi imikhono eslayidayo emikhawulweni yomibili yesinxephezelo ihlale ishelela ngokukhululekile kungakhathaliseki ukuthi okuphakathi kugeleza kuphi kusuka kusinxephezelo, ukuze kuzuzwe isinxephezelo sezindlela ezimbili nokwandisa inani lesinxephezelo.
