316L/TP316L Stainless Simbi Pipe

Giredhi 316L inoreva S31603 UNS desination 1.4404, ine giredhi iri nani yekuramba pane TP316 nekuda kweiyo Carbon yepasi.316L yakanyanya kabhoni yemukati 0.03% iyo 316 inokwana 0.08%, yakakwira kabhoni inowedzera intergranular corrosion.Naizvozvo, 316L inokodzera maapplication uko kabhoni kunaya kunoda kudzivirirwa.Iyi simbi isina tsvina inoshandiswa zvakanyanya kugadzira zvinhu, iyo yakakosha kabhoni yemukati yakasanganiswa newelding inovimbisa yakanyanya kupikisa kune general corrosion, kunyanya inoshanda kune inorema basa zvinhu.

316L inoonekwa seyakashingirira kune oxidation kupfuura Type 316, kunyanya munzvimbo dzinodziya dzemugungwa.Zvekare, yakaderera kabhoni yemukati inoidzivirira kubva kune kabhoni kunaya.Iyo simbi inoratidzawo kuramba pane yakanyanya kuderera tembiricha, kunyangwe pasi kusvika kumazinga ecryogenic.Panyaya yekudzivirira kupisa, 316L inoratidza zvirinani kunyura, kutsemuka kusagadzikana kuramba uye simba rose kupfuura mamwe mamakisi esimbi asina tsvina.

Mazhinji emaitiro akafanana ekushanda ayo anoshanda kune Type 316 anogona zvakare kushandiswa kune 316L, kusanganisira weldability uye kutonhora kuomesa basa.Pamusoro pezvo, 316 haidi post-service annealing kuti iwedzere kusatana kwayo nekuora, asi annealing inogona kushandiswa mune dzimwe nguva.

316H/TP316H Stainless Simbi

Giredhi 316H inoreva S31609, kabhoni yemukati 0.04% kusvika 0.10%, inopa yakakwirira tembiricha kuramba kupfuura 316L.

316Ti/TP316Ti

Simbi isina simbi 316Ti inozivikanwa segiredhi yakagadzikana yemhando ye316 uye zvakare iri imwe yeaviri 316 simbi isina tsvina inokurudzirwa kune yakakwira tembiricha yekushandisa.Giredhi iri rine kashoma (kazhinji 0.5%) yetitanium.Kunyange ichiri kugovera akawanda ezvivakwa zvemamwe 316 mamakisi, kuwedzera kwetitanium kunodzivirira 316Ti kubva mukunaya pakunaya kwepamusoro, kunyangwe nekuratidzwa kwenguva refu.

Molybdenum inowedzerwawo kune kuumbwa kwe316Ti.Kufanana nemamwe mamakisi 316, molybdenum inopa yakawedzera dziviriro kubva mukuora, chloride solution pitting uye simba kana yaiswa munzvimbo dzekushisa kwepamusoro.Nekudaro, iyo yakanyanya kupisa tembiricha inosanganiswa neiyo titanium yemukati, iyo inoita kuti 316Ti isadzivirirwe kune kunaya pane idzi tembiricha.Mukuwedzera, iyo simbi inopikisa kune acids yakadai sesulfuric acid, hydrochloric acid, uye acid sulfates.
316Ti inowanzo shandiswa mukutsinhana kupisa, midziyo yekugadzira mapepa uye zvinhu zvekuvaka munzvimbo dzemugungwa.

TP316LN/316N

316N: Nitrogen (N) inowedzerwa kune 316 simbi isina tsvina kuti iwedzere simba pasina kuderedza plastiki, kuitira kuti kukora kwezvinhu zvideredzwe.Zvekusimba kwepamusoro zvikamu zvine nani corrosion resistance.

316LN yakafananawo 316L ine N yakawedzerwa, ine zvirinani corrosion resistance pane 316N.

TP316/316L/316H/316Ti Stainless Steel Pipe Applications

TP316 / 316L isina musono pombi inoshandiswa kune mvura kana gasi kudzvanywa kwekufambisa mukurapwa kwemvura, marara emvura kurapwa, petrochemical, makemikari, mishonga uye mamwe maindasitiri.Uye zvimiro zvekushandisa zvinosanganisira handrails, mapango uye pombi yekutsigira yemvura yemunyu uye nharaunda dzinoparadza.Kana ichienzaniswa neTP304 simbi isina tsvina, TP316 simbi isina simbi pombi ine yakaderera weldability, saka haishandiswe kakawanda sepombi yakashongedzerwa kunze kwekunge yakakwira corrosion resistance inodarika weldability.
