Kutheni i-Stainless Steel U-Tube Heat Exchanger kunye neFlange Connections zisengozini yokubola

Izitshintshi zobushushu zizinto ezibalulekileyo kumashishini amaninzi, ukusuka kwizityalo zamandla kunye nezibonelelo zepetrochemical ukuya ekulungisweni kokutya kunye nemveliso yamayeza. Phakathi koyilo olwahlukeneyo, izitshintshi zobushushu ze-U-tube zisetyenziswa kakhulu ngenxa yokukwazi kwazo ukujongana nokwandiswa kobushushu, uyilo oluncinci, kunye nokudluliselwa kobushushu ngokufanelekileyo. Nangona kunjalo, ingxaki enye eqhelekileyo abajongene nayo abaqhubi kukugqwala kweetyhubhu zesitshintshi sobushushu se-U-tube sentsimbi engagqwaliyo kwindawo yoqhagamshelo lweflange.

Eli nqaku liphonononga isizathu sokuba kubekho ezi ngxaki zokugqwala, iindlela ezibandakanyekayo, kunye nendlela iinjineli kunye nabaqhubi bezityalo abanokunciphisa ngayo iingozi. Ngokuqonda izizathu, kuba lula ukukhetha izixhobo ezifanelekileyo, izinto eziqwalaselwayo kuyilo, kunye neendlela zokulungisa ukuze kwandiswe ubomi benkonzo yezixhobo.

Ulwakhiwo lwe-U-Tube Heat Exchanger

Isixhobo sokutshintsha ubushushu se-U-tube siquka oku kulandelayo:

  • Iphakheji yeThubhu:Iityhubhu zentsimbi engatyiwayo ezigobileyo zibe yi-U ukuze zibe yilwe kancinci.

  • Iphepha leTube kunye neeFlanges:Iityhubhu zifakwa kwishiti yetyhubhu zize zitywinwe ngeeflange ukuze ziqhagamshelwe kwipayipi yangaphandle.

  • Icala leShell:Iqokobhe elikhulu elijikeleze ityhubhu, apho ulwelo olunye luphuma khona.

  • Icala letyhubhu:Ulwelo luhamba ngaphakathi kwiityhubhu ze-U zentsimbi engatyiwayo.

Indawo yeflange yindawo ebalulekileyo apho ukuthintela ukuvuza, ukutywina, kunye nokumelana nokugqwala kufuneka kulawulwe ngononophelo.

Isizathu Sokuba Kwenzeka Ukugqwala KwiiFlange Connections

1. Ukonakala kweCrevice

Uqhagamshelo lweflange ludala izithuba ezincinci kunye neengxunya phakathi kweegasket, iibholiti, kunye nomphezulu weflange. Ezi ngxunya zihlala zibamba ulwelo olungashukumiyo, zivumela ukuba kubekho uxinzelelo lweoksijini olwahlukileyo. Le meko ikhawulezisa ukugqwala kwendawo ethile, nokuba kwintsimbi engatyiwayo.

2. Ukubola kweGalvanic

Ukuba kusetyenziswa iintsimbi ezahlukeneyo kwindibano yeflange, ezifana neeflange zentsimbi yekhabhoni ezidityaniswe neetyhubhu ze-U zentsimbi engatyiwayo, ukubola kwe-galvanic kunokwenzeka. Umahluko we-electrochemical potential phakathi kweentsimbi ukhokelela ekuboleni okukhawulezileyo kwindawo yokudibana.

3. Ukuphotha Okubangelwa yiChloride

Iintsimbi ezingenasici ezifana ne-304 okanye i-316 zinokuba neengxaki zokutsalwa yi-chloride xa zichatshazelwe ngamanzi olwandle, i-brine, okanye ulwelo olune-chloride. Indawo yeflange, kuba kunzima ukuyicoca nokuyihlola, iba yindawo eshushu yokuhlaselwa yi-chloride.

4. Ukubola kweGasket

Izinto ze-gasket ezinganeleyo zinokonakala phantsi kobushushu obuphezulu okanye iikhemikhali ezirhabaxa, zishiya izithuba ukuze ulwelo olurhabaxa lungene luze luhlasele umphezulu wentsimbi engagqwaliyo.

5. Ukuqhekeka koxinzelelo (SCC)

Iindawo zeFlange ziphantsi koxinzelelo olukhulu ngenxa yokuqiniswa kweebholithi kunye nokwandiswa kobushushu. Xa zidityaniswe neekloride okanye ubushushu obuphezulu, le meko yoxinzelelo inokubangela ukuqhekeka kwentsimbi engagqwaliyo.

6. Uxinzelelo lweZingcolisi

I-flange joint idla ngokuqokelela ukungcola, inkunkuma, kunye neentsalela zeekhemikhali. Olu xinzelelo lwendawo lwezingcolisi lukhawulezisa ngakumbi ukugqwala xa kuthelekiswa nezinye iindawo ze-exchanger.

Amanqanaba eNtsimbi Engagqwaliyo aqhelekileyo kwi-U-Tube Heat Exchangers

  • 304 Intsimbi Engagqwaliyo:Ukumelana nokugqwala ngokubanzi, kodwa ukumelana neekloridi kuncinci.

  • Intsimbi Engagqwaliyo engama-316 / 316L:Ukumelana ngcono ne-chloride pitting, esetyenziswa kakhulu kwimizi-mveliso yaselwandle neyeekhemikhali.

  • 321 Intsimbi Engagqwaliyo:Izinzile nge-titanium, ilungele ukusetyenziswa kubushushu obuphezulu.

  • Iintsimbi Ezingenasici Ezimbini (2205, 2507):Ukumelana okugqwesileyo nokuqhekeka koxinzelelo kunye namandla aphezulu.

  • Intsimbi Engagqwaliyo ye-904L:Ukumelana okuphezulu kwii-asidi kunye neekloride, ezisetyenziswa rhoqo kwiindawo ezinobungozi beekhemikhali.

Nangona ziluncedo, kwanala manqanaba anokujongana nokugqwala kwendawo ukuba uyilo lweflange, ukutywinwa, kunye nokugcinwa kwazo azanelanga.

Izicelo Zemizi-mveliso apho kuvela khona iingxaki zokugqwala

  1. Ukuveliswa koMbane:Izifudumezi zamanzi kunye nezikhuseli zebhoyila zihlala zifumana ukubola kweflange ngenxa yokuguquguquka kwekhemikhali yamanzi.

  2. Izityalo zePetrochemical:Ii-process fluids ezityebileyo kwi-chloride zihlasela iindawo ze-gasket kunye nee-flanges.

  3. Izityalo zokususa ityuwa emanzini:Ukuvezwa kwamanzi olwandle kukhawulezisa ukubola kwemingxuma kunye nokuqhekeka kwamalungu.

  4. Ukutya Neziselo:Iintsalela kwiindawo ezisicaba zinokubangela ukugqwala okubangelwa ziintsholongwane ukuba azicocwanga kakuhle.

  5. Ishishini leMithi:Iinkqubo zamanzi ezicocekileyo kakhulu zifuna ukuvalwa okugqibeleleyo, kodwa ukuvuza okuncinci kukhuthaza ukugqwala kwemisele.

Iziphumo Zokugqwala KwiziXhobo Zokuqhagamshela I-Flange

  • Ukuncipha kokusebenza kokuvala, okukhokelela ekuvuzeni.

  • Ukulahleka kokusebenza kakuhle kwe-heat exchanger ngenxa yomonakalo wetyhubhu.

  • Ukunyuka kweendleko zokulungisa kunye nexesha lokungasebenzi elingalindelekanga.

Ukusebenzisa izinto zokukhusela okanye ukuvala iiplanga kumphezulu weflange kunokunyusa ukumelana nokugqwala.

4. Ukhuseleko lweCathodic

Kwezinye iinkqubo, ukhuseleko lwe-cathodic lunokusetyenziswa ukunciphisa ukugqwala kwe-galvanic.

5. Ukugcinwa Nokuhlolwa Okufanelekileyo

  • Ukuhlolwa rhoqo kweendawo zeflange ngexesha lokuvalwa.

  • Ukucoca iintsalela kunye neentsalela ukuze kuthintelwe ukuxinana kweentlobo ezidlakadlaka.

  • Ukutshintsha ii-gaskets ngamaxesha athile acwangcisiweyo.

6. Iindlela Eziphuculweyo Zokwenza Izinto

  • Kuphephe ukungcola ngexesha lokushisela nokuhlanganisa.

  • Qinisekisa ukuba iindawo ezigudileyo kwiindawo ezidityanisiweyo zithe tyaba ukuze kuncitshiswe imingxunya.

  • Sebenzisa i-torque elawulwayo kwiibholithi ukuthintela uxinzelelo olugqithisileyo.

Umzekelo woFundo lweTyala

Kwisityalo sokukhupha ityuwa, izitshintshi zobushushu zentsimbi engagqwaliyo ezingama-316L U-tube zadibaniswa neeflange zentsimbi yekhabhoni. Kwiminyaka emibini, kwabonwa ukubola okukhulu kwiiflange ngenxa yemiphumo ye-galvanic kunye nokuvezwa kwamanzi olwandle. Emva kokuphuculwa ukuya kwiiflange zentsimbi engagqwaliyo ezimbini kunye neegasket ze-PTFE, isityalo sisebenze iminyaka engaphezu kwe-10 ngaphandle kweengxaki ezinkulu zokugqwala.

Iindlela Zekamva Kwizinto Zokutshintsha Ubushushu

Njengoko amashishini efuna ukuthembeka okuphezulu kunye nobomi benkonzo ende, ukusetyenziswa kweentsimbi ezikumgangatho ophezulu ezingenasici, ii-super austenitic alloys, kunye nee-alloys ezisekelwe kwi-nickel kuya kwanda. Utshintsho kwizixhobo ze-gasket kunye nobuchwepheshe bokuvala i-flange luya kunciphisa ngakumbi umngcipheko wokugqwala kwizicelo ezibalulekileyo.

Kutheni ufuna iityhubhu zentsimbi engagqwaliyo kunye nezixhobo ezivela kwi-sakysteel

Xa uyila kwaye usebenzisa izitshintshi zobushushu, ukukhetha umthengisi ofanelekileyo kubaluleke kakhulu njengokukhetha izinto ezifanelekileyo.i-sakysteelIbonelela ngoluhlu olubanzi lweetyhubhu zentsimbi engagqwaliyo, iiflanges, kunye nezixhobo ezihambelana nemigangatho ye-ASTM, ASME, kunye ne-EN. Ngolawulo oluqinileyo lomgangatho, izixhobo zokuhlola eziphambili, kunye nokupakishwa okulungele ukuthunyelwa kwamanye amazwe,i-sakysteeliqinisekisa ukuthembeka nokusebenza kwexesha elide kwizicelo ze-exchange yobushushu kwimizi-mveliso kwihlabathi liphela.

Isiphelo

Ukugqwala kwi-flange connection ye-stainless steel U-tube heat exchangers yingxaki eqhelekileyo kodwa enokuthintelwa. Izinto ezifana nokugqwala kwe-crevice, ukugqwala kwe-galvanic, ukuhlaselwa kwe-chloride, kunye nokuwohloka kwe-gasket zonke zinegalelo kumonakalo wendawo.
