Izihlungi Zensimbi Engagqwali vs Hastelloy: Yini Ongayikhetha Ngokuhlunga Kwezimboni?

Isingeniso

* Uhlolojikelele lwezihlungi ze-Porous Metal

Izihlungi zensimbi ezinezimbotshanaziyingxenye ebalulekile ezinqubweni eziningi zezimboni, ezaziswa ngekhono lazo loku

hlukanisa izinhlayiya, lawula ukugeleza, futhi uphathe izindawo eziyingozi kakhulu. Yenziwe ngezimpushana zensimbi ezisikiwe

ndawonye ukuze kwakhiwe isakhiwo esinezimbotshana eziningi, lezi zihlungi zibalulekile ngenxa yokuqina kwazo, ukusebenziseka kabusha, kanye

amakhono okuhlunga aqondile. Asetshenziswa kuzo zonke izimboni ezifana nemithi, ukucubungula amakhemikhali,

ukukhiqizwa kokudla neziphuzo, uwoyela negesi, nokunye, kuqinisekisa ukusebenza okuphephile nokusebenza kahle kwemishini nezinqubo.

* Gxila ku-Hastelloy vs Stainless Steel

Phakathi kwezinto ezihlukahlukene ezisetshenziselwa ukukhiqizaizihlungi zensimbi ezinama-porous, I-Hastelloykanye ne-Stainless Steel yizinto ezimbili

izinketho ezivame kakhulu ezikhethiwe ngenxa yezakhiwo zazo ezihlukile. I-Hastelloy, ingxubevange esekwe nickel, idume ngayo

ukumelana okuvelele kokugqwala nokusebenza emazingeni okushisa aphezulu. Ngakolunye uhlangothi, iStainless Steel,

ikakhulukazi i-316L, inikeza isixazululo esingabizi kakhulu nesiguquguqukayo esinokumelana nokugqwala okuqinile,

ukuyenza ibe yizinto ezisetshenziswayo eziningi zezimboni.

* Inhloso

Le bhulogi ihlose ukusiza amaklayenti anqume ukuthi iyiphi impahla—i-Hastelloy noma i-Stainless Steel—ezifanelekela kangcono izidingo zawo zokuhlunga.

Ngokuqonda izakhiwo zento ngayinye kanye nezimo aphumelela ngaphansi kwazo, amaklayenti azohlonyiswa kangcono

ukwenza isinqumo esinolwazi esiqinisekisa ukusebenza kwesikhathi eside kanye nokuphumelela kwezindleko ezicelweni zabo ezithile.

2. Ukuqonda Impahla

1. I-Hastelloy

I-Hastelloy iwumndeni wama-alloys asekelwe ku-nickel aziwa ngokumelana nokugqwala okukhethekile nokusebenza kwezinga lokushisa eliphezulu.

Zivame ukusetshenziswa ezindaweni ezinzima lapho ezinye izinto zingahluleka.

Ukwakheka nezici:

*Ngokuyinhloko yakhiwe nge-nickel, i-molybdenum, nensimbi.

*Iqukethe amanani ahlukahlukene ezinye izici ezifana ne-chromium, i-tungsten, ne-cobalt ukuze ihlanganise izici ezithile.

*Zaziwa ngokumelana kwazo okuhle kakhulu ne-oxidation, i-pitting, nokugqwala kwemifantu.

Izici ezibalulekile:

*Imboni ye-Petrochemical:

Isetshenziswa ezinqubweni zokucwenga ngenxa yokumelana kwayo nezinhlanganisela ezinesulfure.

2. Insimbi Engagqwali

Insimbi engagqwali iwumndeni wama-alloys asekelwe ku-iron aziwa ngokumelana nokugqwala kanye nezakhiwo ezinhle zokukhanda.

Zisetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yokuguquguquka kwazo nokuqina.

Ukwakheka nezici:

*Ngokuyinhloko yakhiwe ngensimbi ne-chromium.

*Ukwengezwa kwezinye izakhi ezifana ne-nickel, i-molybdenum, ne-carbon kungashintsha izici zayo.

*Insimbi engagqwali engu-316L iyibanga elijwayelekile elaziwa ngokumelana kahle nokugqwala kwemigodi nokugqwala, ikakhulukazi ezindaweni ezine-chloride.

Izici ezibalulekile:

*Ukumelana nokugqwala:

Imelana nokugqwala nokugqwala, iyenze ifanelekele ukusetshenziswa kwangaphandle.

*Amandla omshini:

Inikeza amandla okuhle okuqina, i-ductility, nobulukhuni.

*Kulula ukuhlanza nokunakekela:

Inobuso obushelelezi obumelana namabala nokushintsha kombala.

Izinhlelo zokusebenza ezidumile:

*Imboni yokudla neziphuzo:

Isetshenziswa ezintweni ezithinta ukudla neziphuzo, njengamasinki, ama-countertops, nezitsha.

*Imboni yezemithi:

Iqashwe emishinini yokukhiqiza kanye namathangi okugcina ngenxa yezindawo zayo zokuhlanzeka.

*Izinhlelo zokusebenza ze-Architectural:

Isetshenziselwa izinto zokwakha, njenge-cladding, ama-railing, nezingxenye zesakhiwo.

*Amadivayisi ezokwelapha:

Isetshenziswa kumathuluzi okuhlinza, izimila, nezinye izisetshenziswa zezokwelapha.

Kafushane, kuyilapho kokubili i-Hastelloy nensimbi engagqwali kunikeza ukumelana nokugqwala okuhle kakhulu, i-Hastelloy ifaneleka kangcono ezindaweni ezidlulele ngenxa yokuqukethwe kwayo okuphezulu kwe-nickel nokusebenza okuphezulu kwezinga lokushisa. Insimbi engagqwali, ikakhulukazi i-316L, iyinto eguquguqukayo enokumelana nokugqwala okuhle kanye nezakhiwo zemishini, okuyenza ifanelekele uhla olubanzi lwezinhlelo zokusebenza.

3. I-Hastelloy vs Insimbi Engagqwali

3. Ukuqhathanisa Ukusebenza

1.) Ukumelana Nokugqwala

*I-Hastelloy:

Iyaziwa ngokumelana kwayo nokugqwala okukhethekile ezindaweni eziningi ezahlukahlukene, kufaka phakathi i-acidic,

i-alkaline, nezimo eziqukethe i-chloride. Imelana ikakhulukazi nomgodi, ukugqwala kwemifantu, kanye nokuqhekeka kokugqwala kwengcindezi.

*Insimbi Engagqwali (316L):

Inikeza ukumelana nokugqwala okuhle, ikakhulukazi ezindaweni ezine-chloride. Nokho,

ukumelana kwayo kungase kukhawulwe ezimweni ezinolaka kakhulu noma lapho kuvezwe ezinhlotsheni ezithile zama-asidi.

2.) Izinhlelo zokusebenza lapho ukumelana nokugqwala kubalulekile:

*Ukucutshungulwa kwamakhemikhali:

I-Hastelloy ivame ukusetshenziswa emishinini yokuphatha amakhemikhali abolayo, njenge-sulfuric acid ne-hydrochloric acid, ngenxa yokumelana kwayo okuphezulu.

*Izindawo zasolwandle:

Ukumelana okuhle kakhulu kwe-Hastelloy emanzini olwandle kuwenza alungele izingxenye ezifana nezishintshisi zokushisa namasistimu amapayipi.

*Imboni ye-Pulp nephepha:

I-Hastelloy isetshenziswa emishinini ehlangana notshwala obudlayo.

3.)Ukumelana Nokushisa

*I-Hastelloy:

Isebenza kahle kakhulu ekusetshenzisweni kwezinga lokushisa eliphezulu, igcina izakhiwo zayo zokulungisa nokugqwala emazingeni okushisa aphakeme.

Ivamise ukusetshenziswa ezindaweni lapho insimbi engagqwali ingahluleka khona ngenxa ye-oxidation noma ukulahlekelwa amandla.

*Insimbi Engagqwali (316L):

Nakuba ikwazi ukumelana namazinga okushisa amaphakathi, ukusebenza kwayo kungase kwehle emazingeni okushisa aphakeme, ikakhulukazi ezindaweni ezine-oxidizing.

4.) Izimo lapho u-Hastelloy enza kahle khona:

*Izicelo zokushisa okukhulu:

I-Hastelloy isetshenziswa ezimbonini ezifana ne-aerospace, i-petrochemical, kanye nokukhiqiza amandla,

lapho izingxenye zichayeka emazingeni okushisa aphezulu nasezindaweni ezinokhahlo.

5.) Amandla Mechanical

*I-Hastelloy:

Inikeza izakhiwo ezinhle kakhulu zemishini, kufaka phakathi amandla aphezulu okudonsa, i-ductility, nokumelana nokukhathala.

Ilungele izinhlelo zokusebenza ezidinga kokubili ukumelana nokugqwala kanye nobuqotho besakhiwo.

*Insimbi Engagqwali (316L):

Ihlinzeka ngezakhiwo ezinhle zokusebenza, kodwa ingase ingabi namandla njenge-Hastelloy kwezinye izinhlelo zokusebenza.

Lapho kufanele ubeke phambili insimbi engagqwali:

*Ukusebenza kahle kwezindleko ezindaweni ezinesidingo esiphansi:

Ngenkathi i-Hastelloy inikeza ukusebenza okuphezulu, ingabiza kakhulu kunensimbi engagqwali.

Kuzinhlelo zokusebenza ezinezidingo zokugqwala okumaphakathi kanye namazinga okushisa aphansi okusebenza,

insimbi engagqwali ingase ibe inketho engabizi kakhulu.

Ngokufigqiwe,I-Hastelloy iyisinqumo esingcono kakhulu sezinhlelo zokusebenza ezidinga ukumelana nokugqwala okukhethekile,

ukusebenza okuphezulu kwezinga lokushisa, kanye nezakhiwo ezinhle kakhulu zemishini. Nokho, insimbi engagqwali ingaba yinto esebenzayo

inketho ezinhlelweni ezinezidingo ezingadingi kakhulu nezindleko eziphansi.

Ukukhethwa phakathi kwe-Hastelloy nensimbi engagqwali kuncike ezidingweni ezithile zohlelo lokusebenza,

kucatshangelwa izici ezifana nemvelo yokugqwala, izinga lokushisa lokusebenza, kanye nezakhiwo ezidingekayo zemishini.

Nali ithebula elifingqa amaphuzu abalulekile empendulweni edlule:
