ERW carbon steel yeeb nkabvs kauv cev:

Ua ntej, qhov sib txawv ntawm cov txheej txheem ntau lawm
ERW carbon steel yeeb nkab yog kub dov coil los ntawm kev nruam yob txoj kev, siv high-frequency tam sim no ntawm daim tawv nqaij nyhuv thiab zoo sib xws, thiaj li hais tias tus ntug ntawm lub coil tshav kub fusion, siab nyob rau hauv lub nyem cov menyuam nyob rau hauv lub siab welding kom ua tiav ntau lawm.Yog li ntawd, erw carbon steel yeeb nkab residual kev nyuaj siab yog me me, los ntawm kev kho cua sov vuam, sizing, straightening, dej siab thiab lwm yam txheej txheem, cov residual kev nyuaj siab rau ntxiv tso tawm thiab txo.Kev xyaum tau ua pov thawj tias erw carbon steel yeeb nkab hauv kev khaws cia thiab siv cov kev ntxhov siab ntawm cov yeeb nkab steel tsis cuam tshuam.Yog tsis muaj vuam hlau, qhov vuam nyob rau hauv lub cev muaj zog thiab tshuaj muaj pes tsawg leeg nrog lub phaj raws nraim tib yam.Qhov zoo ntawm erw carbon steel yeeb nkab nyob ntawm qhov zoo ntawm daim ntawv.

Kauv steel yeeb nkab los ntawm chav tsev kauv rotary vuam hlau welding ua ke, cov hlau phaj los ntawm cov kauv kev sib hloov, thiaj li hais tias cov geometric kev nyuaj siab yog complex, thiab ib txhia txawm mus txog lub yield txwv ntawm cov hlau phaj, kauv raj tom qab tsim ntawm ib tug. loj residual stress, residual stress yog tensile stress.Thiab cov yeeb nkab steel los ntawm lub siab sab hauv, phab ntsa kuj tsim lub nplhaib tensile kev nyuaj siab, ob qho tib si superimposed, kom lub peev xwm tsis muaj zog ntawm cov yeeb nkab steel.Kev siv cov txheej txheem tsis muaj kev nyab xeeb dua.Cov hlau phaj yog welded ua ke los ntawm ib tug hlau uas muaj tshuaj muaj pes tsawg leeg, thiab npuas thiab weld hlaws tawg yuav tshwm sim thaum lub sij hawm vuam txheej txheem.Yog li ntawd cov weld thiab lub hauv paus hlau nyob rau hauv lub cev muaj zog thiab tshuaj muaj pes tsawg leeg yog kom meej meej sib txawv.Nws yog ib qho yooj yim los tsim kom muaj kev ntxhov siab loj hauv kev sib koom tes nrog lub hauv paus hlau.Nyob rau hauv cov txheej txheem vuam, cov nyhuv tshav kub yog loj, thiab hardness yog siab.

Qhov thib ob, qhov sib txawv ntawm cov khoom siv raw
ERW carbon steel yeeb nkab siv nyob rau hauv cov ntaub ntawv raw yog tsim los ntawm cov kub-kuav los tiag kauj, tshuaj muaj pes tsawg leeg thiab lub cev muaj zog muaj zog dua.

Feem ntau ntawm cov kauv yeeb nkab cog siv rau qib qis kub-kuav los tiag sawb, tshuaj lom neeg muaj pes tsawg leeg thiab lub cev muaj zog thiab tsis ruaj khov, muaj kev puas tsuaj sab hauv thiab impurities ntau dua.Tsuas yog nyob rau hauv cov roj thiab petrochemical system nyob rau hauv lub loj kauv yeeb nkab manufacturers siv li niaj zaus kub dov kauj los tsim steel yeeb nkab thiaj li yuav ua tau zoo thiab kev nyab xeeb.

Thib peb, cov nqi yuav khoom thiab kev yuav khoom nyuaj
Roj thiab petrochemical system ntawm cov yeeb nkab steel loj ntau lawm ntawm kauv steel yeeb nkab, nws qhov zoo yog feem ntau yog concentrated nyob rau hauv loj txoj kab uas hla steel yeeb nkab raug, raug nqi kuj tsawg.Txawm li cas los xij, rau me me thiab nruab nrab txoj kab uas hla (Φ114mm ~ Φ355.6mm) ntawm cov yeeb nkab steel, cov nqi tsim khoom yog siab dua, qhov nruab nrab siab tshaj ERW steel yeeb nkab 8% mus rau 15%.

Loj kauv steel yeeb nkab cog feem ntau tsis tsim cov kab me me kauv steel yeeb nkab, kev yuav khoom nyuaj dua.Me thiab nruab nrab txoj kab uas hla erw carbon steel yeeb nkab, vim muaj coob tus manufacturers, heev yooj yim mus yuav.

Plaub, steel yeeb nkab geometric loj
1, ERW carbon steel yeeb nkab geometric loj ntawm qhov raug siab dua;thiab kauv welded yeeb nkab geometry qhov tseeb yog qhov tsawg, uas ua rau ntawm qhov chaw tsim kho ntawm qhov chaw weld weld docking nyuaj.
2, ERW carbon steel yeeb nkab weld coefficient yog 100%;kauv welded yeeb nkab weld coefficient ntawm 130% -200%.Qhov ntev ntawm cov kauv yeeb nkab yog ntev npaum li cas ntawm ERW steel yeeb nkab, thiab qhov tsis xws luag kuj nce ntxiv.
3, ERW carbon steel yeeb nkab nyob rau hauv lub vuam yog ze ze rau xoom, qhov muag liab qab tsis pom;kauv steel yeeb nkab sab hauv thiab sab nrauv yuav tsum sab laug txog 0.3 hli siab (uas yog txiav txim los ntawm cov txheej txheem ntau lawm).Lub vuam yog siab heev uas muaj qhov sib txawv ntawm cov txheej (3PE) thiab cov yeeb nkab, uas ua rau corrosion kuj ntawm cov yeeb nkab steel heev txo.

4, Vim muaj qhov sib txawv ntawm kauv steel yeeb nkab, kev sib kis ntawm cov kua dej kub ceev yuav muaj kev cuam tshuam loj, ua kom cov dej ntws tawm, txo cov kev thauj mus los ntawm cov kav dej.ERW carbon steel yeeb nkab phab ntsa yog du, tsis muaj teeb meem zoo li no.
