TP347H-yakagadzika zvinhu (senge titanium kana niobium) austenitic simbi isina tsvina maindasitiri mapaipi akaiswa welded.

TP347H Stainless steel welded pombi ndeye austenitic Stainless simbi yakasarudzika, ndeyeiyo inopisa simba simbi yakatevedzana, ine yakanaka kugadzikana kwekupisa uye intercrystalline corrosion kuramba. Ichi chinyorwa chakanyanya kukodzera kushandiswa mukupisa kwakanyanya, senge mu boiler superheater machubhu, reheater machubhu, pombi dzehutsi, uye petrochemical heat exchangers. TP347H Yakanaka welding kuita kwesimbi isina simbi yakashongedzwa pombi, iyo inobvumira kuti ichengetedze kutendeseka kwezvinhu uye kusagadzikana kwekuora panguva yekugadzira.

TP347H Zvimiro zvesimbi isina tsvina yakashongedzwa pombi dzinosanganisira:

Thermal simba: inogona kuramba ichichengetedza yakanaka michina zvivakwa pakupisa kwakanyanya.

Kupokana kune intercrystalline corrosion: nekuwedzera niobium (Nb) sechigadziro, intercrystalline corrosion inodzivirirwa zvinobudirira.

Corrosion resistance: inoratidza kumira zvakanaka kwekuora mualkaline, mvura yegungwa uye dzakasiyana siyana acidic nharaunda.

Welding performance: yakakodzera kune welding process, inogona kuve nechokwadi chemhando uye kuvimbika kweiyo weld.

Panyaya yekushandiswa, TP347H simbi isina tsvina yakashongedzwa pombi inoshandiswa zvakanyanya mujenareta seti, boiler superheater chubhu, reheater chubhu, pombi yehutsi uye petrochemical heat exchanger uye imwe tembiricha yakanyanya uye yakanyanya kudzvanywa nharaunda. Pamusoro pezvo, inokodzera maantioxidant mamiriro, ine inotenderwa antioxidant tembiricha inosvika 750 ℃.

Pakusarudza nekushandisa TP347H simbi isina simbi yakashongedzwa pombi, zvinhu zvinosangana neanoenderana zviyero zvepasi rese, senge ASTM A213 uye ASTM A312, iyo inotsanangudza chimiro chemakemikari, michina zvivakwa uye zvinodiwa zvekugadzira. Pamusoro pezvo, nekuda kwehunhu hwekushandisa pakupisa kwepamusoro, zvakakoshawo kuti usarudze nzira dzakakodzera dzewelding uye zvinhu zvewelding kuti ive nechokwadi chemhando yeweld seam uye kusimba kwechimiro chese.
