Hauv kev tsim kho kev lag luam hauv lub tebchaws, cov kav dej kub-dov seamless steel yeeb nkab yog ib qho tseem ceeb ntawm steel qhov rooj qeb. Nws kuj yog ib qho irreplaceable siab-kev nyab xeeb yooj yim raw khoom rau roj thiab roj drilling thiab khoom tsim.
Cov txheej txheem ntau lawm ntawm kub-dov seamless steel kav muaj ob yam ntxwv. Ib qho yog tias cov txheej txheem ntawm cov kav dej pore dov muaj qhov loj deformed tsis kam. Feem ntau, kev tsim cov txheej txheem yuav tsum ua kom tiav cov txheej txheem tsim ntawm qhov kub deformation ntau dua li lwm cov hlau kub-dov; Cua txias hauv huab cua, tsis muaj kev tswj kom txias txoj kev.
Kev tshuaj xyuas thiab ntxuav ntawm qhov chaw tsis xws luag ntawm lub raj khoob
Qhov chaw tsis xws luag ntawm lub raj (scarring, concave pits, grooves, cracks, thiab lwm yam) feem ntau siv cov khoom cuav ntawm lub qhov muag (yog tias muaj cov kev cai tshwj xeeb, koj yuav tsum siv txoj kev tshawb nrhiav uas tsis yog kev puas tsuaj) rau kev tshuaj xyuas, thiab tom qab ntawd ntxuav qhov tsis xws luag. . Txhawm rau tiv thaiv kev kuaj xyuas tsis tu ncua, qhov saum npoo ntawm qhov chaw tuaj yeem raug kuaj xyuas thiab ntxuav tom qab lub raj khoob tau khaws los yog txau (xuab zeb tsuag).
Cov txheej txheem ntawm kev ntxuav qhov tsis xws luag ntawm lub raj yog tsuas yog nplaim taws ntxuav, xuab zeb sib tsoo thiab ntxuav thiab tig tu. Rau cov pa roj carbon steel yeeb nkab blanks uas tsis muaj cov kab nrib pleb, ntxuav cov nplaim taws; steel hom uas muaj zog rhiab heev, xws li siab alloy steel yeeb nkab blanks, xuab zeb log sib tsoo thiab tu; qee yam tshwj xeeb steel hom, xws li stainless hlau, corrosion-resistant alloy Tube blanks, thiab lwm yam, yuav tsum tau muab ntxuav los ntawm qhov chaw tsav tsheb tev tawm.
Qhov tsis zoo yog tias lub raj khoob yog ntxuav los ntawm lub turbine lossis txoj kev sib tsoo ntawm lub log. Txoj kev nplaim hluav taws raug ntxuav, thiab kev ua haujlwm ntau lawm yog siab, tab sis qhov zoo ntawm lub raj pam tsis zoo li kev tu los ntawm kev tig los yog xuab zeb sib tsoo.
