316 Stainless Simbi Pipe
Inenge 316L pombi yesimbi isina tsvina
316L igiredhi resimbi isina tsvina, AISI 316L inoenderana zita rekuAmerica, uye sus 316L ndiro rinoenderana zita rechiJapan.kodhi yenyika yangu yakabatana yedhijitari iS31603, iyo yakajairwa giredhi 022Cr17Ni12Mo2 (itsva chiyero), uye giredhi rekare 00Cr17Ni14Mo2, zvinoreva kuti inonyanya kuve neCr, Ni, uye Mo, uye nhamba yacho inomiririra inenge muzana.
Iyo yakanyanya kabhoni yemukati ye316 Stainless simbi pombi ndeye 0.03, iyo inogona kushandiswa mumashandisirwo apo annealing mushure mewelding haigone kuitwa uye yakanyanya kuomarara kuramba inodiwa.
316 uye 317 Stainless simbi (ona pazasi kune zvimiro zve 317 Stainless simbi) ane molybdenum-ine Stainless simbi.
Kuitwa kwese kwegiredhi resimbi iri kuri nani pane kwe310 uye 304 simbi isina tsvina.Pasi pemamiriro ekupisa kwepamusoro, apo sulfuric acid yakaderera pane 15% uye yakakwirira kudarika 85%, 316 simbi isina tsvina ine zvakawanda zvekushandisa.
316 Stainless simbi ndiro, inozivikanwawo se 00Cr17Ni14Mo2 corrosion resistance:
Kupokana necorrosion kuri nani pane 304 simbi isina tsvina, uye ine yakanaka yekurasa kuramba mukugadzirwa kwe pulp nebepa.
Iyo carbide precipitation resistance ye316 Stainless simbi iri nani pane iya ye304 Stainless simbi, uye tembiricha iri pamusoro inogona kushandiswa.
316l Stainless simbi pombi yenyika chiyero
316L igiredhi resimbi isina tsvina, AISI 316L inoenderana zita rekuAmerica, uye sus 316L ndiro rinoenderana zita rechiJapan.kodhi yenyika yangu yakabatana yedhijitari iS31603, iyo yakajairwa giredhi 022Cr17Ni12Mo2 (itsva chiyero), uye giredhi rekare 00Cr17Ni14Mo2, zvinoreva kuti inonyanya kuve neCr, Ni, uye Mo, uye nhamba yacho inomiririra inenge muzana.Iyo yenyika chiyero ndeye GB/T 20878-2007 (yazvino vhezheni).
316L ine huwandu hwakawanda hwemashandisirwo muindasitiri yemakemikari nekuda kweiyo yakanakisa corrosion kuramba.316L zvakare inotorwa kubva ku18-8 mhando austenitic simbi isina tsvina, ine 2 kusvika 3% yeMo yakawedzera.Pahwaro hwe316L, mamakisi mazhinji esimbi anotorwawo.Semuenzaniso, 316Ti inotorwa mushure mekuwedzera zvishoma zveTi, 316N inotorwa mushure mekuwedzera zvishoma zveN, uye 317L inotorwa nekuwedzera zvinyorwa zveNi neMo.
Mazhinji eiyo 316L aripo pamusika anogadzirwa zvinoenderana neAmerican Standard.Nekuda kwezvikonzero zvekudhura, zvigayo zvesimbi zvinowanzoedza kudzikisa zvirimo zveNi zvezvigadzirwa zvavo kusvika pamuganho wakaderera.Chiyero cheAmerica chinoti Ni content ye316L i10-14%, ukuwo Japanese standard ichiti Ni content ye316L i12-15%.Zvinoenderana neiyo diki mwero, pane 2% mutsauko muNi yemukati pakati peAmerican standard neJapan standard, iyo yakakura kwazvo maererano nemutengo.Naizvozvo, vatengi vachiri kuda kuona zvakajeka kana vachitenga zvigadzirwa zve316L, ingave zvigadzirwa zvichireva ASTM kana JIS zviyero.
Iyo Mo yemukati ye316L inogadzira iyi simbi ine yakanakisa kuramba kugomba ngura uye inogona kushandiswa zvakachengeteka munzvimbo dzine Cl- uye mamwe ma halogen ions.Sezvo 316L ichinyanya kushandiswa kune ayo emakemikari zvimiro, zvigayo zvesimbi zvine zvishoma zvakaderera zvinodiwa kuti zviongororwe pamusoro pe316L (zvichienzaniswa ne304), uye vatengi vane yepamusoro yepamusoro zvinodiwa vanofanirwa kusimbisa kutarisisa kwepasi.
Kugadzirisa uye kucheneswa kwesimbi isina tsvina
Kana simbi isina tsvina yakafumurwa kumhepo kwenguva yakareba, inozosvibiswawo sechinhu chero chipi zvacho.Zvidzidzo zvakaratidza kuti nzira mbiri dzakasiyana dzekuwacha kwemvura uye kugeza nemawoko dzine hukama hwakati nenzvimbo yakasviba yesimbi isina tsvina.Kutanga, isa imwe simbi isina tsvina mumhepo uye imwe mucanopy kuti uone kushanda kwekunaya kwemvura.Kushanda kwechiponji chekugadzira chakanyikwa mumvura ine sipo kuti chigaro gadzirisa nzvimbo yemachira, uye nguva yacho imwedzi mitanhatu yekukwesha.Nekuda kweizvozvo, iwo maslats akange asina kunyungudutswa mushedhi aive aine guruva shoma pamusoro peiyo yakanyungudutswa slats pane iyo yakanyungudutswa munzira mbiri.Nokudaro, nguva yekuchenesa yesimbi isina tsvina inogonawo kukanganiswa nezvinhu zvakawanda.Muhupenyu, tinogona kungochenesa simbi isina tsvina patinochenesa girazi, asi kana simbi isina tsvina iri kunze, inokurudzirwa kuishambidza kaviri pagore.
