Hauj lwm lawm
Gnee Steel (Tianjin) Co., Ltd. yog ib qho ntawm feem kev manufacturers thiab lwm tus neeg ntawm astm a312 tp304l stainless hlau seamless yeeb nkab nyob rau hauv Suav teb. Nrog kev paub ntau, peb sov siab txais tos koj rau cov lag luam wholesale customized astm a312 tp304l stainless hlau seamless yeeb nkab los ntawm peb lub hoobkas. Rau nqe kev sab laj, tiv tauj peb.
Raws li kev ntseeg siab thoob ntiaj teb cov khoom lag luam, GNEE tau xa tawm TP304L stainless hlau welded kav mus rau ntau tshaj 80 lub teb chaws thoob ntiaj teb, nrog cov khoom xa tuaj txhua xyoo ntau tshaj 2,000 tons. Peb cov ntaub ntawv raw yog tsim los ntawm cov khoom tsim nyog steel mills nruab nrog cov txheej txheem traceability, kom ntseeg tau tias txhua pawg ntawm cov khoom tuaj yeem taug qab mus rau tus lej tshwj xeeb thiab tau ua pov thawj los ntawm PMI (Positive Material Identification) kuaj.
Peb cov ASTM A312 TP304L seamless kav yog tsim tshwj xeeb rau kev siv siab - siab heev. Los ntawm kev siv Qib A VOD / AOD refined billets, peb nruj me ntsis tswj cov ntsiab lus carbon kom tsawg dua lossis sib npaug li 0.030% thiab cov ntsiab lus sulfur kom qis dua 0.005%. Tsis tas li ntawd, tag nrho cov SS 304L cov kav dej tau txais kev daws teeb meem ntawm qhov kub thiab txias (Ntau dua lossis sib npaug rau 1040 degree) ua raws li ceev ceev quenching; Cov txheej txheem no ua kom muaj kev tsim cov austenitic microstructure tag nrho nrog cov qauv zoo li qub, tiv thaiv carbide nag lossis daus thiab txhim kho cov khoom tiv thaiv rau intergranular corrosion.
Hais txog phab ntsa thickness uniformity thiab eccentricity, phab ntsa thickness kam rau ua rau peb ASTM A312 TP304L round kav dej yog feem ntau tswj nyob rau hauv ± 10%, nrog ib tug eccentricity ntawm tsawg tshaj li los yog sib npaug rau 10%. Qhov no ua kom muaj kev ntxhov siab tsis sib xws thoob plaws hauv cov yeeb nkab thaum ua haujlwm, yog li tshem tawm cov ntsiab lus tsis muaj zog.
Rau peb cov ASTM A312 TP304L kub- dov seamless kav, peb siv cov txheej txheem pickling thiab passivation los xyuas kom meej tias ob qho tib si sab hauv thiab sab nrauv yog huv si ntxuav ntawm zeb nplai, roj residues, thiab ntau yam kab mob. Qhov saum npoo roughness feem ntau tswj tau rau Ra Tsawg dua lossis sib npaug li 0.8 μm, zoo txo qhov kev pheej hmoo ntawm kev ntsuas thiab pib ntawm corrosion. Los ntawm cov kev ntsuas no, peb tau ua tiav daws teeb meem ntau yam teeb meem los ntawm peb cov neeg siv khoom xws li corrosion ntxov ntxov, tsis sib xws ntawm phab ntsa tuab, thiab kev hloov pauv zoo.

FAQ
Q: Dab tsi yog cov txheej txheem tsim khoom rau ASTM A312 TP304L seamless kav?
Kub Tiav: Cov kav dej yog tsim los ntawm qhov kub thiab txias uas siv cov txheej txheem extrusion los yog tho.
Cold Finished (piv txwv li, Cold Drawn / Cold Rolled): Cov kav dej tau ua tiav ntawm qhov kub thiab txias.
Q2: Vim li cas TP304L nyiam dua TP304 hauv siab -siab seamless piping systems?
Qhov "L" nyob rau hauv qib kev xaiv sawv cev rau "Low Carbon," qhia txog cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.035%. Qhov no zoo tiv thaiv "sensitization" (piv txwv li, nag lossis daus ntawm carbides ntawm cov ciam teb nplej) thaum lub sij hawm vuam, yog li xyuas kom meej tias cov yeeb nkab tuav tau zoo heev tiv thaiv intergranular corrosion nyob rau hauv lub tshav kub-Tshwj xeeb cheeb tsam (HAZ).
Q3: Dab tsi yog "Dual Certification" (304/304L) rau seamless kav xa mus rau?
Gnee nquag muab cov kav dej seamless featuring "Dual Certification." Cov khoom no muaj cov yam ntxwv qis - carbon cov yam ntxwv ntawm qib 304L (ua kom zoo weldability) thaum tib lub sij hawm ua tau raws li cov kev xav tau ntawm lub zog siab dua -xws li lub zog tensile thiab lub zog tawm los- qhia rau qib 304 tus qauv. Qhov kev sib xyaw ua ke ntawm cov khoom no tso cai rau cov engineers siv cov kev tsim qauv siab dua yam tsis muaj kev cuam tshuam corrosion.
