Ukusuka ekubunjweni kwifom, uluhlu lwezinto ezinefuthe kwimpawu zeemveliso zentsimbi ezingenasimo. Enye yezona zinto zibalulekileyo zenqanaba lensimbi lokuyisebenzisa. Oku kuyakuchaza uluhlu lweempawu kwaye, ekugqibeleni, zombini iindleko kunye nexesha lokuphila kweemveliso zensimbi ezingalunganga.
Ke wazi njani ukuba uqale phi?
Ngelixa zonke izicelo zahlukile, le mibuzo i-7 ibonisa ukuqwalaselwa okubaluleke kakhulu ekuncedeni ukuba unciphise ukhetho lwakho kwaye ufumane amabakala afanelekileyo kwiimfuno zakho okanye isicelo sakho.
1. Loluphi uhlobo lokuxhathisa ifunelwa yintsimbi?
Xa ucinga ngentsimbi engenasibala, izinto zokuqala eziza engqondweni zinokumelana nee-Acids kunye ne-chlolordes - ezinjengezo zifunyenwe kwizicelo zemveliso okanye kwiindawo zaselwandle. Nangona kunjalo, ukumelana kobushushu kuyinto ebalulekileyo.
Ukuba ufuna ukunganyangeki kwe-corosion, uyakufuna ukuphepha amachaphaza afundela amafutha kunye neMartiaticic. Amabakala anesini angenasitali angenasitali kwiindawo ezinobuchule kubandakanya i-austistitic okanye izabelo zeDulex njengamaBanga 304, 304, 3165, kunye ne-904l.
Kumaqondo aphezulu obushushu, amabakala e-austicoitic ahlala engcono. Ukufumana ibanga eline-chromium ephezulu, i-silicon, initrogen, kunye nezinto ezinqabileyo zomhlaba ziya kutshintsha amandla ensimbi yokumelana namaqondo obushushu aphezulu. Amabakala aqhelekileyo kwiindawo eziphakamileyo zobushushu zibandakanya i-310, S30815, kunye nelama-446.
Amabakala entsimbi ye-Austelitic akwalungele amaqondo obushushu aphantsi okanye indawo ye-cryogenic. Ukunganyangeki kongezwe, unokujonga kwikhabhoni esezantsi okanye amabakala aphezulu eItrogen. Amabakala aqhelekileyo kwiindawo zobushushu ezisezantsi zibandakanya i-304, 30ln, 310, 316, kunye ne-904l.
2. Ngaba intsimbi yam ifuna ukuba yenziwe?
Intsimbi enemigangatho engalunganga iya kuba yi-brittle ukuba isebenza kakhulu kwaye inike indlela esezantsi. Kwiimeko ezininzi, amayeza aMayeza akakhuthazwa. Ngaphaya koko, intsimbi enemilo ephantsi isenokungayi kubamba imilo yayo xa kusenziwa i-conricate okanye ukwenziwa kwentsusa.
Xa ukhetha ibanga lentsimbi, uya kufuna ukuqwalasela ifom othanda ukuyiswa. Nokuba ufuna iintonga, ii-slabs, imivalo okanye amashiti ayakunciphisa ukhetho lwakho. Umzekelo, amantshontsho e-Ferricwo ahlala ethengiswa emakhithini, amayeza aseMartiaticic ahlala athengiswa kwimivalo okanye ii-slabs, kunye nezitho ezi-ausments ezikhoyo kwiifom ezibanzi. Amanye amabakala ensimbi efumaneka kwiifom ezahlukeneyo zibandakanya 304, 316, 430, 2205, ne-3CR12.
3. Ngaba intsimbi yam ifuna ukuba ngoomatshini?
I-Maching ayiyongxaki. Nangona kunjalo, ukusebenza nzima kunokuvelisa iziphumo ezingalindelekanga. Ukongezwa kwe-sulfure kunokuphucula ukwenziwa koomatshini kodwa kunciphisa ukwenziwa, i-uqhelane kunye nokunganyangeki.
Oku kwenza ukuba ufumane ibhalansi phakathi koomatshini kunye nokunganyangeki kwe-corrosion uqwalaselo olubaluleke kakhulu kwiinkqubo zensimbi yensimbi engenasiseko. Kuxhomekeka kwiimfuno zakho, amaBanga angama-303, 436, 430, kunye ne-3ccc12 inikele ibhalansi elungileyo apho ukuqhubela phambili ukhetho.
4. Ngaba ndidinga ukuzimela ngentsimbi?
I-welding yensimbi inokukhokelela kwingxaki-kubandakanya ukuqhekeza okushushu, kunye nokungakhathali nokungakhathali-kuxhomekeke kwinqanaba lensimbi esetyenzisiweyo. Ukuba uceba i-Weld yentsimbi ye-Stainess, izabelo ze-Austitac zilungile.
Amabakala e-Carbon anokukunceda ngakumbi ngokuqhekeka ngelixa engongezwayo, anjenge-Niobium, anokuzinzisa isabelo sokuphepha izinto ezixhalabisayo. Inqanaba elidumileyo lensimbi engenasibala ibandakanya i-304L, 316, 347, 437, 439, 439.
5. Ngaba unyango olushushu luyafuneka?
Ukuba isicelo sakho sifuna unyango lobushushu, kufuneka uqwalasele indlela asabela ngayo amabakala entsimbi yentsimbi. Iimpawu zokugqibela zeentsimbi ezithile zihlukile kakhulu ngaphambi nasemva konyango lobushushu.
Kwiimeko ezininzi, uMartiaticic kunye nolwalamano oluninzi, onjenge-440c okanye i-17-4 pH, anikele elona ntsebenzo lihle kakhulu xa unyango. Iziqwenga ezininzi ezingenazizathu ezingenasiseko azinalutho xa i-shart inyangwa kwaye ke azilunganga ukhetho.
6. Ngawaphi amandla entsimbi ilungile kwisicelo sam?
Amandla ensimbi yinto ebalulekileyo ekufuneka uyiqwalasele ukhuselo lokhuseleko. Ukanti, ngokugqithileyo kunokukhokelela kwiindleko ezingafakwanga, ubunzima, kunye nezinye izinto ezichithakeleyo. Iimpawu zempawu zimiselwa ngokukhululekileyo kusapho lwensimbi kunye nokwahluka okuthe kratya okufumaneka kumabakala ahlukeneyo.
7. Ithini indleko yexabiso ngaphambili kunye nexabiso lokuphila lentsimbi kwindawo yam?
Zonke izinto eziqwalaselwayo zangaphambili zitya owona mbuzo ubalulekileyo ekukhetheni indleko zensimbi yensimbi. Ukutshatisa amabakala ensizi engenasimo kwindalo ekujolise kuyo, ukusetyenziswa kunye neemfuno, unokuqinisekisa ukusebenza ixesha elide kunye nexabiso elikhethekileyo.
Thatha inkathalo yokuhlalutya ukuba intsimbi iya kwenza njani kwixesha lokusetyenziswa kwaye zeziphi iindlela ezinokubandakanyeka kulondolozo okanye zokutshintshwa ngaphambi kokuthatha isigqibo. Ukuncitshiswa kweendleko kufikeleleko kunokubangela inkcitho engakumbi ngaphezulu kobomi beprojekthi yakho, imveliso, isakhiwo, okanye esinye isicelo.
Ngenani lamanqanaba ensimbi kunye neefom ezifumanekayo, ukuba nengcali yokunceda ukhetho kunye nemingxunya enokubakho yindlela ebalaseleyo yokuqinisekisa ukuba ufumane ixabiso lokutyala kwentsimbi engenasinyithi. Njengomboneleli ophambili wensimbi engaphezulu kweminyaka engama-20, iqela lensimbi kaJindalai liya kuzinyusa amava ethu ukunceda ukukukhokela kwinkqubo yokuthenga. Jonga uluhlu lwethu olubanzi lweemveliso ezingenamandla kwi-intanethi okanye umnxeba ukuze uxoxe ngeemfuno zakho nelungu leqela lethu.
