Seamless SMLS Yeeb Nkab Txheej Txheem
Raw Material Xaiv:High-quality carbon steel yog xaiv los ua raw khoom rau seamless carbon steel kav. Cov ntsiab lus carbon hauv cov hlau yog qhov tseem ceeb hauv kev txiav txim siab nws cov khoom thiab tsim nyog rau ntau yam kev siv.
Cua sov thiab Piercing:Cov khoom siv raw yog rhuab mus rau qhov kub thiab txias thiab tom qab ntawd pierced los ua ib lub plhaub hollow. Cov txheej txheem no yog qhov tseem ceeb heev rau kev tsim cov yeeb nkab thawj zaug thiab feem ntau ua tiav los ntawm txoj hauv kev xws li kev sib tsoo, extrusion, lossis lwm yam txheej txheem tshwj xeeb.
Rolling thiab Sizing:Lub plhaub pierced undergoes dov thiab sizing txheej txheem los txo nws txoj kab uas hla thiab phab ntsa thickness rau qhov yuav tsum tau qhov ntev. Qhov no feem ntau ua tiav siv cov dov mills thiab sizing mills kom ua tiav cov duab thiab qhov ntev.
Kev kho cua sov:Seamless carbon steel yeeb nkab yog raug rau cov txheej txheem kho cua sov xws li annealing, normalizing, lossis quenching thiab tempering los txhim kho nws cov khoom siv kho tshuab thiab tshem tawm cov kev ntxhov siab uas seem. Kev kho cua sov kuj tseem pab ua kom tiav qhov xav tau microstructure thiab cov khoom ntawm cov pa roj carbon steel.
Kev kuaj thiab tshuaj xyuas:Thoob plaws hauv cov txheej txheem tsim khoom, cov yeeb nkab seamless carbon tau dhau los ua ntau yam tsis muaj kev puas tsuaj thiab kev puas tsuaj los xyuas kom nws ua tau raws li cov qauv tsim nyog. Qhov no yuav suav nrog kev kuaj ultrasonic, kuaj hydrostatic, kuaj tam sim no, thiab kuaj pom.
Finishing thiab Txheej:Thaum seamless yeeb nkab ua tau raws li qhov yuav tsum tau ua, nws ua tiav cov txheej txheem xws li kev ncaj, txiav, thiab xaus. Tsis tas li ntawd, cov yeeb nkab yuav raug coated nrog cov ntaub ntawv tiv thaiv xws li kua roj vanish, xim, los yog galvanizing los txhim kho nws cov corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm carbon hlau.
Kev tshuaj xyuas zaum kawg thiab ntim khoom:Cov yeeb nkab seamless steel tiav tiav kev tshuaj xyuas zaum kawg kom ntseeg tau tias nws ua tau raws li cov qauv zoo thiab cov neeg siv khoom xav tau. Nws yog tom qab ntawd ua tib zoo ntim thiab npaj rau kev xa mus rau cov neeg siv khoom.
API 5L Carbon Steel Seamless Yeeb Nkab Kev Ua Haujlwm Zoo thiab Kev Xeem
Hydrostatic xeem
seamless yeeb nkab yuav tsum tiv thaiv qhov kev ntsuam xyuas hydrostatic yam tsis muaj to los ntawm lub vuam seam los yog cov yeeb nkab lub cev.
