** 1. Peb hom hlau kav hlau yog dab tsi? **
Peb hom kev sib tw ntawm cov hlau hlau yog cov yeeb nkab carbon hlau, cov yeeb nkab steel, thiab tooj liab yeeb nkab.
** 2. Dab tsi yog qhov muaj zog tshaj hom hlau? **
Hom muaj zog tshaj plaws ntawm cov yeeb nkab hlau feem ntau yog tsim los ntawm cov hlau hlau lossis cov alloys tshwj xeeb zoo li chromoly (chromium- molybdenum hlau). Lawv lub zog, tshwj xeeb tshaj tawm thiab tensile lub zog, tshwj xeeb heev, tshwj xeeb tshaj yog thaum piv rau tsis- ferrous kav li tooj liab lossis txhuas. Lub zog tag nrho tuaj yeem sib txawv tau ntau raws li cov qib ntawm cov hlau thiab nws cov txheej txheem tsim khoom (piv txwv li, seamless vs. welded).
** 3. Dab tsi yog cov yeeb nkab steel? **
Ib cov yeeb nkab steel yog ib lub raj kheej cylindrical ua los ntawm cov hlau, ib co hlau ntawm hlau thiab carbon. Nws yog feem ntau siv los thauj cov kua, gases, slurries, thiab hmoov tshuaj. Vim nws lub zog thiab lub zog, nws tseem muaj dav siv raws li cov txheej txheem sib xyaw ua kev tsim kho thiab tsim khoom.
** 4. Dab tsi yog qhov sib txawv ntawm cov kav hlau steel? **
Cov khoom lag luam hlau mas tsuas yog coolerorized los ntawm lawv cov khoom tsim tsim khoom: ** Seamless kav dej ntawm cov hlau, ua rau lawv muaj zog thiab siv rau kev siv siab thiab siv rau kev siv siab. ** WELDED PIPES ** yog ua los ntawm dov hlau mus rau hauv coil thiab vuam sab sauv; Lawv muaj ntau dua thiab raug nqi -} Siv tau txiaj ntsig zoo rau nruab nrab siab siv siab. Lawv kuj tau muab cais los ntawm cov khoom, xws li ** cov hlau roj carless thiab kub {{{{4 4 {{4 4 {4 4 {4 4 {
** 5. Vim li cas nws hu ua yeeb nkab? **
Lo lus "yeeb" pib los ntawm Latin lo lus "* Lub ntsiab lus" rau chirp lossis peep, "uas hloov mus rau tub sab suab paj nruag (zoo li lub raj nplaim). Lub koom haum no nrog lub tog raj kheej hollow rau cov suab nrov tom qab ncua ntev rau ib qho ntev, hollow raj siv siv rau kev siv cov tshuaj uas siv rau kev sib txuas. Hauv kev tsim khoom, "yeeb nkab" feem ntau yog hais txog cov raj siv rau kev thauj cov roj, thaum "raj" feem ntau yog hais txog nws cov txheej txheem sab nraud.
