ASTM A312 SP304L Seamless Stainless Hlau Yeeb yog qhov zoo tagnrho rau nws cov ntsiab lus carbon ntau dua (muaj txiaj ntsig kev tiv thaiv cov corrosion). Nws muaj cov kws kho tshuab zoo, kev muaj zog, thiab kev ua yeeb yam zoo, thiab ua tau zoo nyob rau hauv ob qho tib si qis {- kev siv kub. Nws lub ntsiab kom zoo rau dej kho cov lus dag nyob rau hauv nws lub peev xwm los tiv thaiv ntau yam ntawm kev tawm xov xwm thiab chaw ib puag ncig. Txawm li cas los xij, nws yuav tsum raug sau tseg tias nws yuav raug kev cuam tshuam rau pitt caterposion hauv qhov chaw sov sov.
Dab tsi yog cov specifications rau 304 stainless hlau seamless yeeb nkab?
ASTM A312 CTP304 Stainless Hlau Yeeb Nkab yog tsim nyog rau siab- qhov siab kub (txog 870 degrees Celsius) thiab lub zog. Qhov tsawg kawg los lees lub zog ntawm 304 stainless hlau yeeb nkab (unsless steel yeeb nkab (unsw) yog 205 MPa, thiab lub zog tsawg tshaj plaws yog 515 mpa.
ASTM A312 TP.34L (unc uns s30403) stainless hlau seamless hlab rau dej kho
ASTM A312 TPP3L yog qhov qis-} cov roj carbon aus roj stainless hlau. ASTM A312 TP30L stainless hlau hlab muaj ib tug zoo tshaj plaws nickel {}} cov ntsiab lus chromium, txhim kho lawv cov corrosion tsis kam thiab oxidation tsis kam. Cov hlab no tseem muaj zog dua thiab haum rau qhov siab- qhov kev siv dej kom sov.
ASTM A312 TP30L stainless hlau seamless hlab, tiv thaiv cov khoom lag luam zoo dua, thiab lub zog zoo thiab kev ua kom muaj zog ntawm cov kub tsawg.

Kev txiav txim siab tseem ceeb rau kev kho cov dej
Chloride kev sib tw: thaum tiv taus dej haus hauv ambient ib puag ncig, thiab kev nyuaj siab corrosion ib puag ncig tuaj yeem tshwm sim saum toj kwv yees li 600 degree.
Kev kuaj: Pipelines yuav tsum yauv hydrostatic kuaj kom ntseeg tau tias lawv lub zog thiab kev khi. Lwm yam kev ntsuam xyuas, xws li EDDY kev sim tam sim no, kev sim tshuaj siv, lossis ntsuas hluav taws xob, tuaj yeem ua thaum thov.
Kev kho deg: cov kav dej tiav yuav tsum muaj du, xws li cov kev kho uas tsis kam, uas muaj txiaj ntsig zoo rau kev kho cov dej.
Gnee steel tshwj xeeb hauv kev tsim cov khoom ntau ntawm cov khoom lag luam stainless hlau. Gnee Steel cov khoom ntim khoom muaj xws li: cov hlua hlau: cov kav hlau: cov kav hlau nrog cov kab yeeb yaj kiab txheej lossis tsawg dua yog cov xeb thaum hiav txwv thaum hiav txwv thaum hiav txwv, thiab tom qab ntawd ruaj ntseg nrog hlau strapping. Cov kab mob ntoo / crates: pipes feem ntau ntim rau hauv cov tsiaj ntoo lossis crates los tiv thaiv cov kav dej thaum thauj mus los, tshwj xeeb yog cov uas nyob ntev dua lossis cov kab hniav loj dua. Seaworthy export ntim: Cov chaw muag khoom siv cov txheej txheem seaworthy export export cov ntaub ntawv sau thiab cov tswv yim los tiv thaiv cov kav dej thaum lub sijhawm thauj mus los. Tarpaulin Ntim: Qhov no tiv thaiv los nag, seawater, thiab lwm yam sab nraud los ntawm kev nkag mus rau lub crates export thaum thauj mus los. GNEE steel tshwj xeeb hauv kev tsim khoom thiab muag khoom ntawm alloy cov ntaub ntawv.
