Yechokwadi 316L Stainless simbi pombi ine yakavimbiswa zvinhu
316 Stainless simbi mutopota imhando mhango refu raundi simbi, izvo zvinowanzoshandiswa maindasitiri kutapurirana mapaipi uye michina structural zvikamu zvakadai peturu, makemikari indasitiri, kurapwa, zvokudya, chiedza indasitiri, michina uye zviridzwa, etc. Uyezve, kana kukotama uye simba rekurovera kwakafanana, huremu hwakareruka, saka hunoshandiswawo zvakanyanya mukugadzirwa kwemechini zvikamu uye zvimiro zveinjiniya. Inoshandiswawo inowanzoshandiswa mukugadzirwa kwemhando dzakasiyana-siyana dzezvombo, mbiya, mabhomba, etc. Kusiyana-siyana: 316 simbi isina tsvina pombi, 316 simbi isina tsvina inopenya pombi, 316 simbi isina tsvina yekushongedza pombi, 316 simbi isina tsvina capillary, 316 simbi isina tsvina welded pombi, 304 pombi yesimbi isina tsvina.
Iyo yakanyanya kabhoni yemukati ye1316l Stainless simbi pombi ndeye 0.03, iyo inogona kushandiswa mumashandisirwo apo annealing haigone kuitwa mushure mewelding uye yakanyanya corrosion resistance inodiwa. 316 Stainless simbi pombi ine yakanyanya kabhoni yemukati ye0.03 uye inogona kushandiswa mumashandisirwo apo annealing haigone kuitwa mushure mewelding uye yakanyanya corrosion kuramba inodiwa.
316 uye 317 Stainless steels (ona zvinotevera kune zvivakwa zve 317 Stainless simbi) ari molybdenum ine Stainless simbi.
Kuita kwese kwesimbi iyi kuri nani pane 310 uye 304 simbi isina tsvina. Pasi pemamiriro ekushisa kwepamusoro, apo sulfuric acid yakaderera pane 15% uye yakakwirira kudarika 85%, 316 simbi isina tsvina ine zvakasiyana-siyana zvekushandisa.
316 Stainless simbi ndiro, inozivikanwawo se 00Cr17Ni14Mo2, corrosion resistance:
Kudzivirirwa kwecorrosion kuri nani pane 304 simbi isina tsvina uye ine yakanaka corrosion resistance mukugadzira pulp nebepa.
Iyo carbide precipitation resistance ye316 Stainless simbi iri nani pane iya ye304 Stainless simbi, uye tembiricha iri pamusoro inogona kushandiswa.
Stainless simbi pombi imhando yegomba refu kutenderera simbi, iyo inoshandiswa zvakanyanya mumaindasitiri ekutapurirana mapaipi akadai sepetroleum, indasitiri yemakemikari, kurapwa, chikafu, indasitiri yemwenje, michina zviridzwa uye michina yezvimiro zvikamu. Pamusoro pezvo, kana kupeta uye simba rekurovera kwakafanana, huremu hwakareruka, saka hunoshandiswawo zvakanyanya mukugadzira zvikamu zvemakanika uye zvimiro zveinjiniya. Iyo inowanzoshandiswa mukugadzirwa kwezvombo zvakasiyana-siyana, mbiru, mabhomba, nezvimwewo. Rudzi urwu rwepombi yesimbi inogona kukamurwa kuita simbi isina musono pombi uye simbi isina tsvina yakashongedzwa nenyere (slotted pombi). Zvinoenderana neakasiyana maitirwo ekugadzira, inogona kukamurwa kuita akati wandei emhando mhando: inopisa rolling, extrusion, inotonhora kudhirowa uye kutonhora kutenderera. Zvinoenderana nechimiro chechikamu, inogona kukamurwa kuita denderedzwa pombi uye yakakosha-yakaumbwa pombi. Circular simbi pombi inoshandiswa zvakanyanya, asi kune zvakare mamwe masikweya, rectangular, semicircular, hexagonal, equilateral triangle Octagonal uye mamwe akakosha-akaumbwa-stainless simbi pombi.
Muedzo weHydraulic uchaitirwa iyo pombi yesimbi inotakura mvura yekumanikidza kuyedza kuramba kwayo uye kunaka. Inokodzera kana pasina kuvuza, kunyorova kana kuwedzera pasi pekumanikidzwa kwakataurwa. Mamwe mapombi esimbi anozovewo pasi pekuyedzwa kwecrimping, kuyedza kuyedza uye kuyedza kufefetera zvinoenderana nechiyero kana zvinodiwa zveanoda.
304L Stainless simbi pombi ndeyepasi rose Stainless simbi yekumaka nzira. 304L simbi isina tsvina pombi -- s30403 (AISI, ASTM)
Iyo Chinese brand inoenderana ne304L ndeye 00Cr19Ni10
Hunhu uye kushandiswa: simbi ine yakaderera kabhoni yemukati pane 0Cr19Ni9 ine yepamusoro intergranular corrosion kuramba. Icho chikamu pasina kupisa kurapwa mushure mekuputika.
Kuverenga uye kumiririra kwesimbi
① International makemikari element zviratidzo uye zviratidzo zvenyika zvinoshandiswa kumiririra chimiro chemakemikari, uye mavara echiArabic anoshandiswa kumiririra chikamu chemukati:
Somuenzaniso: China, Russia 12CrNi3A
②International Stainless steel marking method: shandisa manhamba akagadzika kumiririra simbi dzakatevedzana kana manhamba; Somuenzaniso, United States, Japan, 300 dzakatevedzana, 400 dzakatevedzana uye 200 dzakatevedzana; IAmerican Iron uye Steel Institute inoshandisa manhamba matatu kuona akasiyana magiredhi esimbi isingagadzirike. Pakati pavo, austenitic simbi isina tsvina inoratidzwa nenhamba dze200 uye 300 dzakatevedzana, uye ferritic uye martensitic simbi isina tsvina inoratidzwa nenhamba dze400 dzakatevedzana. Simbi isina tsvina, kunaya kwemvura inoomesa simbi isina tsvina uye alloy yakakwira ine simbi isingasviki 50% kazhinji inotora zita repatent kana zita rekutengesa.
③ Iyo serial nhamba inoumbwa nemavara echiLatin uye kurongeka, izvo zvinongoratidza chinangwa.
Uyezve, 316 simbi isina tsvina zvakare inopokana nemakungwa uye ane hukasha maindasitiri mamiriro. 316 simbi isina tsvina ine yakanaka oxidation kuramba mukushandiswa kwepakati nekupisa kupikisa pazasi 1600 ℃ uye kushandiswa kunoramba kuripo pazasi 700 ℃.
Mukati me800-1575 madhigirii, zviri nani kuti usarambe uchiita 316 simbi isina tsvina, asi kana 316 simbi isina tsvina ichiramba ichishandiswa kunze kweiyi tembiricha renji, simbi isina tsvina ine yakanaka yekupisa. Iyo carbide precipitation resistance ye316L simbi isina tsvina iri nani pane iya ye316 Stainless simbi, uye tembiricha iri pamusoro inogona kushandiswa.
