347 Stainless Hlau Round Yeeb Nkab

Thaum lub sij hawm tsim cov txheej txheem ntawm 347 Stainless Hlau Round Pipe, cov txheej txheem tseem ceeb hauv qab no yuav tsum tau tswj xyuas kom cov yeeb nkab ua tau zoo:

Tshuaj muaj pes tsawg leeg: Cov khoom siv yuav tsum muaj qhov sib npaug ntawm cov ntsiab lus xws li chromium ({{0}}%), nickel ({1}}%), thiab carbon (max 0}{{6} }8%), nrog rau qhov sib ntxiv ntawm niobium (0.8-1.0%) uas muab stabilization tiv thaiv intergranular corrosion. Qhov no yog ib qho tseem ceeb rau kev tswj cov alloy qhov corrosion kuj thiab mechanical zog.

Annealing: Kev kho cua sov kom zoo, xws li annealing, yog qhov tseem ceeb rau kev daws kev ntxhov siab thiab ua tiav cov khoom xav tau. Cov txheej txheem no yuav pab rov qab ductility thiab seem stability tom qab txias ua hauj lwm los yog vuam .

Vuam: Vim yog cov khoom siv siab chromium thiab npib tsib xee cov ntsiab lus, yuav tsum tau saib xyuas tshwj xeeb thaum lub sij hawm vuam kom tsis txhob cuam tshuam intergranular corrosion thiab tswj cov yeeb nkab corrosion kuj. Kev kho cua sov ua ntej thiab tom qab vuam yuav tsim nyog, tshwj xeeb tshaj yog rau cov ntu hnyav lossis thaum vuam cov khoom sib txawv.

Mechanical Properties: Saib xyuas lub zog tensile, yield zog, thiab elongation kom paub tseeb tias lawv ua tau raws li qhov tsawg kawg nkaus tus nqi teev rau 347 stainless hlau, xws li lub zog tensile yam tsawg kawg nkaus ntawm 90-120 ksi (620-830 MPa).

Nto tiav: Qhov saum npoo ntawm cov yeeb nkab tuaj yeem cuam tshuam nws qhov kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive. Xyuas kom lub ntsej muag tsis muaj nplai, tawg, thiab lwm yam tsis xws luag.

Kev kuaj tsis yog kev puas tsuaj (NDT): NDT txoj kev xws li kev kuaj ultrasonic, radiography, lossis eddy tam sim no kuaj yog siv los xyuas kom meej tias tsis muaj kev puas tsuaj sab hauv lossis tsis zoo hauv cov yeeb nkab.

Lub tuam txhab kom zoo dua

gnee yog ib lub tuam txhab kev lag luam thiab kev ncaj ncees steel thoob ntiaj teb kev lag luam, uas yog tsim los ntawm ib pab pawg ntawm cov neeg ua haujlwm paub txog thiab txaus siab rau, ua raws li lub tswv yim ntawm "zoo thiab kom muaj nuj nqis lav". Peb ntseeg hais tias los ntawm peb txoj kev cog lus muaj zog, peb yuav yog koj qhov kev xaiv zoo tshaj plaws los muab kev daws teeb meem thiab daws teeb meem hauv kev lag luam steel.
