Masiqale ngenyani:
Imibhobho ye-Austenitic stainless steel isetyenziswa ngokuqhelekileyo kwiindidi zeendawo ezinobungozi. Nangona kunjalo, ukuba uyaqaphela, uya kufumanisa ukuba kumaxwebhu oyilo kwezinye iiyunithi, ixesha elide njenge-DN≤40, zonke iintlobo zezixhobo zamkelwe ngokusisiseko. Kumaxwebhu oyilo lwezinye iiyunithi, imibhobho yensimbi engenasici, kungakhathaliseki ukuba incinci kangakanani i-caliber, zisebenzisa i-butt-welded pipe fittings endaweni ye-tube fittings.
Njengoko ilizwi lihamba: ukuze kuqinisekiswe umgangatho we-welding wemibhobho encinci kwaye ugweme ukungena kwe-welding ngexesha le-welding enkulu yangoku, uxhulumaniso lwe-socket luhlala lusetyenziswa endaweni yokudibanisa i-butt welding. Ke, kutheni ezinye iiyunithi zentsimbi engatyiwa yimibhobho emincinci yekalibhu zingathwali amaqhekeza angaphakathi? Oku kubandakanya ingxaki: umhlwa wokuqhekeka.
Makhe sithethe malunga nokuba yintoni i-crevice corrosion?
Xa kukho umsantsa (ngokubanzi 0.025-0.1mm) kumphezulu amacandelo metal ngenxa imizimba yangaphandle okanye izizathu zesakhiwo, kunzima ukufuduka medium corrosion kwi-gap, nto leyo ekhokelela intsimbi, ebizwa ngokuba i-gap corrosion. I-Crevice corrosion idla ngokuba yimpembelelo yomnye umhlwa (ofana ne-pitting corrosion, i-corrosion yoxinzelelo), ngoko ke iprojekthi izama ukuphepha ukwenzeka kwe-corrosion. Ubukho beentanda kufuneka buphetshwe kuyilo lwesakhiwo semibhobho yesiphakathi esithande ukubola.
Intsimbi engatyiwa 304 flange
Kungenxa yokuba kukho umsantsa kuqhagamshelwano lwesokethi, ngoko ke ezinye iiyunithi ukwenzela ukuphepha umhlwa umsantsa, kuba ubukho umhlwa imibhobho yentsimbi stainless, umbhobho encinane caliber idla ngokusetyenziswa empundu udibaniso welding, ulawulo inkqubo welding ukuqinisekisa umgangatho, ukuphepha. ukusetyenziswa kwe-intubation.
I-304 yintsimbi yendalo yonke, isetyenziswa ngokubanzi kwimveliso yezixhobo kunye neengxenye ezifuna ukusebenza kakuhle okubanzi (ukumelana nokubola kunye nokubumba).
I-304 insimbi engenasici yi-brand yensimbi engenasici eyenziwe ngokuhambelana nemigangatho ye-ASTM e-United States. I-304 ilingana ne-China 0Cr19Ni9 (0Cr18Ni9) yentsimbi engenasici. I-304 iqulethe i-19% yechromium kunye ne-9% ye-nickel.
I-304 yintsimbi esetyenziswa ngokubanzi, intsimbi ekwazi ukumelana nobushushu. Isetyenziswa kwizixhobo zokuvelisa ukutya, izixhobo zekhemikhali ze-xitong, amandla enyukliya, njl.
I-304 yentsimbi yentsimbi ye-welding flangei-chromium esetyenziswa ngokubanzi - i-nickel steel stainless, ene-corrosion resistance, ukumelana nobushushu, amandla aphantsi obushushu kunye neempawu zoomatshini. Ukumelana ne-Corrosion kwi-atmosphere, ukuba yindawo yoshishino okanye indawo engcoliseke kakhulu, kufuneka icocwe kwangethuba ukuphepha ukubola. Ilungele ukulungiswa kokutya, ukugcinwa kunye nokuthutha. Inokusebenza kakuhle kunye ne-weldability. Umtshintshi wobushushu wePlate, i-bellows, iimpahla zasekhaya, izinto zokwakha, iikhemikhali, ishishini lokutya, njl.
