316l Stainless Simbi Seamless Simbi Pipe
304 simbi isina tsvina chinhu chakajairika musimbi isina tsvina, ine density ye7.93 g/cm³;iyo inonziwo 18/8 simbi isina tsvina muindastiri, zvinoreva kuti ine zvinopfuura 18% chromium uye kupfuura 8% nickel;yakakwirira tembiricha kuramba ye800 ℃, yakanaka kugadzirisa kuita, Kuomarara kwakanyanya, kunoshandiswa zvakanyanya muindasitiri uye fenicha yekushongedza indasitiri uye chikafu neindasitiri yekurapa.Nekudaro, zvinofanirwa kucherechedzwa kuti kana zvichienzaniswa neyakajairwa 304 simbi isina tsvina, chikafu-giredhi 304 Stainless simbi ine yakasimba yemukati index.Semuyenzaniso, dudziro yepasi rose ye304 simbi isina simbi inongonzi 18% -20% chromium, 8% -10% nickel, asi chikafu-giredhi 304 simbi isina tsvina ine 18% chromium uye 8% nickel, inobvumira kushanduka mukati meimwe siyana, uye Deredza zviri mukati memhando dzakasiyana-siyana dzinorema.Mune mamwe mazwi, 304 simbi isina tsvina haisati iri chikafu giredhi 304 simbi isina tsvina.
Simbi isina musono pombi mapaipi esimbi anoshingirira kune zvisina kusimba zvinoodza media zvakaita semhepo, chiutsi, uye mvura, uye zvinosvibisa makemikari media seasidhi, alkali, uye munyu.Iyo inozivikanwawo sestainless acid-resistant simbi pombi.
Kupokana kwekuora kwesimbi isina musono pombi kunoenderana nealloying zvinhu zviri musimbi.Chromium ndicho chinhu chakakosha chekupokana nekuora kwesimbi isina tsvina.Kana chromium iri musimbi inosvika 12%, chromium inodyidzana neokisijeni mumhepo inoodza kuita firimu rakatetepa reoxide (self-passivation film) pamusoro pesimbi., Inogona kudzivirira kuwedzera kuparara kwesimbi matrix.Kuwedzera kune chromium, iyo inowanzo shandiswa alloying zvinhu zvesimbi isina musono pombi dzinosanganisira nickel, molybdenum, titanium, niobium, mhangura, nitrogen, zvichingodaro, kuzadzisa zvinodiwa zvekushandisa kwakasiyana-siyana kwechimiro uye kuita kwesimbi isina tsvina.
Stainless simbi isina musono pombi igomba refu raundi simbi, rinoshandiswa zvakanyanya mupetroleum, makemikari, zvekurapa, chikafu, chiedza indasitiri, mechanical instrumentation uye mamwe mapaipi maindasitiri uye mechanicha zvimiro zvikamu.Pamusoro pezvo, kana kupeta uye simba rekurovera kwakafanana, huremu hureruke, saka hunoshandiswawo zvakanyanya mukugadzira zvikamu zvemakanika uye zvimiro zveinjiniya.Inowanzoshandiswa kugadzira zvombo zvakasiyana-siyana, mbiya, mabhomba, nezvimwe.
Iine matanho ekugadzira anotevera:
a.Round simbi kugadzirira;b.Kupisa;c.Kuboorwa kunopisa;d.Cheka musoro;e.Pickling;f.Kugaya;g.Lubrication;h.Cold rolling processing;i.Degreasing;j.Solution kupisa kurapwa;k.Straightening;l.Cheka chubhu;m.Pickling;n.Kuongororwa kwechigadzirwa.
