Seamless raj yog cov raj tsis muaj seams lossis welds. Seamless steel raj raug suav hais tias muaj peev xwm tiv taus siab dua, kub siab dua, siab dua txhua yam kev ntxhov siab thiab corrosive cua.

1. Kev tsim khoom

Seamless steel raj yog tsim los ntawm ntau txoj kev sib txawv. Txoj kev siv nyob ntawm qhov xav tau txoj kab uas hla, lossis qhov sib piv ntawm txoj kab uas hla mus rau phab ntsa tuab, xav tau rau daim ntawv thov xav tau.

Feem ntau, seamless steel raj yog tsim los ntawm thawj casting raw steel rau hauv ib daim ntawv ua hauj lwm ntau dua - ib tug kub khoom billet. Nws yog ces "stretched" thiab thawb los yog rub mus rau lub forming tuag. Qhov no ua rau cov hlab ntsha hollow. Lub raj hollow yog tom qab ntawd "extruded" thiab yuam los ntawm qhov tuag thiab mandrel kom tau qhov xav tau sab hauv thiab sab nrauv phab ntsa diameters.

Txhawm rau kom ntseeg tau tias cov yeeb nkab steel seamless ua tau raws li qee cov qauv, nws yuav tsum raug kho kom sov tshwj xeeb kom ntseeg tau tias nws cov khoom siv hlau ua tau raws li qhov tsim nyog. Thaum xav tau, cov ntaub ntawv tshwj xeeb tsuas yog muaj los ntawm duplex thiab super duplex seamless kav los ntawm NORSOK M650 pom zoo manufacturers. Qhov no ua kom zoo heev thiab kav ntev rau peb cov neeg siv khoom.

2. Daim ntawv thov

Seamless steel raj muaj ntau yam thiab yog li tuaj yeem pom nyob rau hauv ntau qhov chaw. Qhov no suav nrog cov roj thiab roj, refinery, petrochemical, tshuaj, chiv, fais fab thiab tsheb lag luam.
Seamless steel raj feem ntau yog siv los thauj cov kua dej xws li dej, nkev roj, pov tseg thiab huab cua. Nws kuj yog ib txwm xav tau nyob rau hauv ntau lub siab, siab corrosive ib puag ncig nrog rau bearing, mechanical thiab structural puag ncig.

3. Qhov zoo
Lub zog: Seamless steel raj tsis muaj seams. Qhov no txhais tau hais tias qhov ua tau ntawm "tsis muaj zog" seams raug tshem tawm, yog li seamless steel raj feem ntau tuaj yeem tiv taus 20% kev ua haujlwm siab dua li cov welded yeeb nkab ntawm tib cov khoom qib thiab qhov loj me. Lub zog yog tej zaum qhov txiaj ntsig loj tshaj ntawm kev siv seamless steel raj.
Resistance: Lub peev xwm tiv taus siab dua yog lwm qhov txiaj ntsig ntawm kev ua seamless. Qhov no yog vim qhov tsis muaj seams txhais tau hais tias impurities thiab tsis xws luag yuav tsis tshua tshwm sim raws li lawv tshwm sim nyob rau hauv weld.

Kev sim tsawg dua: Qhov tsis muaj welds txhais tau hais tias seamless steel raj tsis tas yuav tsum tau ua tib yam kev ntsuam xyuas nruj zoo li cov yeeb nkab welded. Kev ua haujlwm tsawg dua: Qee qhov seamless steel raj tsis tas yuav tsum tau kho cua sov tom qab fabrication vim lawv harden thaum lub sij hawm ua.
