**1. Qhov twg zoo dua ASTM A106 B lossis ASTM A53 B?
"Zoo" nyob ntawm daim ntawv thov. Txawm li cas los xij, rau siab -kev pabcuam kub, ** ASTM A106 B feem ntau suav tias yog qhov zoo tshaj **.
* ** ASTM A106 ** yog seamless carbon steel yeeb nkab tshwj xeeb tsim los rau siab - qhov kub thiab txias. Nws muaj cov tshuaj lom neeg muaj zog ntau dua thiab cov cuab yeej siv kho tshuab, ua rau nws txhim khu kev qha rau cov ntawv thov tseem ceeb xws li cov chaw tsim hluav taws xob, refineries, thiab cov txheej txheem kab uas kub thiab siab siab.
* ** ASTM A53 B ** yog ib qho dav dav dua - cov yeeb nkab lub hom phiaj, muaj nyob rau hauv ob qho tib si seamless (Hom S) thiab welded (Hom E & Hom F). Thaum A53 Qib B muaj ntau heev thiab muaj zog, nws cov lus qhia tshwj xeeb yog me ntsis nruj dua A106 rau qhov xav tau ib puag ncig.
Rau cov qauv txheej txheem lossis qis- cov ntawv thov cov kav dej siab, A53 B feem ntau txaus thiab tus nqi- zoo. Rau qhov tseem ceeb, siab - kub, lossis siab - cov tshuab siab, A106 B yog qhov yuav tsum tau muaj thiab xaiv zoo dua.
**2. Puas yog A53 thiab A106 tib yam?
Tsis yog, ASTM A53 thiab ASTM A106 tsis zoo ib yam. Lawv yog ob qhov tshwj xeeb tshwj xeeb rau cov pa roj carbon steel yeeb nkab nrog kev siv thiab kev xav tau sib txawv.
Qhov sib txawv tseem ceeb yog lawv thawj daim ntawv thov:
* ** ASTM A53** yog npaj rau kev siv dav dav - lub hom phiaj, qis mus rau nruab nrab - cov ntawv siv siab, xws li cov kav dej, hluav taws xob tiv thaiv, thiab cov kab cua / dej. Nws tuaj yeem yog seamless lossis welded.
* ** ASTM A106 ** tshwj xeeb yog tsim los rau siab - kev pabcuam kub, xws li hauv kev tsim hluav taws xob, refineries, thiab cov txheej txheem kev lag luam. Nws yog feem ntau seamless thiab muaj kev tswj nruj dua ntawm chemistry thiab mechanical zog.
Txawm hais tias A53 Qib B seamless yeeb nkab tej zaum yuav raug siv los hloov A106 B hauv qhov tsis yog- lub luag haujlwm tseem ceeb, lawv tsis tuaj yeem hloov pauv hauv cov lus qhia tshwj xeeb.
**3. A53 yog dab tsi?
"A53" yog lub npe tsim los ntawm **ASTM International** (yav tas los hu ua American Society for Testing and Materials).
* Cov "A" sawv cev rau cov khoom siv ferrous (hlau-raws li).
* Tus "53" tsuas yog tus lej txuas ntxiv rau tus qauv tshwj xeeb no.
Yog li, "ASTM A53" yog lub npe tseem ceeb ntawm tus qauv: "Standard Specification for Pipe, Steel, Dub thiab Kub-Dipped, Zinc-Coated, Welded thiab Seamless." Nws txhais cov kev xav tau rau kev tsim khoom, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev sim rau hom yeeb nkab no.
** 4. Puas yog A106B yeeb nkab seamless?
Yog lawm, feem ntau ntawm ** ASTM A106 Qib B ** yeeb nkab yog seamless. Tus qauv npog tsuas yog seamless yeeb nkab (thiab kuj suav nrog centrifugally cam khwb cia yeeb nkab). Nws tsis npog welded yeeb nkab zoo li ASTM A53 ua. Yog li ntawd, thaum koj xaj A106 yeeb nkab, koj yuav luag ib txwm tau txais cov khoom lag luam seamless, uas yog qhov laj thawj tseem ceeb rau nws siv nyob rau hauv siab -siab thiab siab -kub tshuab.
**5. Qhov twg zoo dua, seamless lossis ERW yeeb nkab?
Tsis muaj qhov "zoo dua" kiag li; qhov kev xaiv nyob ntawm daim ntawv thov, pob nyiaj siv, thiab kev ua haujlwm xav tau.
** Seamless Yeeb Nkab (SMLS):**
** Qhov zoo: ** Tsis muaj vuam seam, ua rau nws muaj zog thiab txhim khu kev qha. Nws muaj cov qauv zoo sib xws, zoo dua tiv taus siab dua, thiab tsis tshua muaj kev ua tsis tiav. Nws yog qhov yuav tsum tau rau cov ntawv thov tseem ceeb tshaj plaws hauv cov roj & roj, cov chaw tsim hluav taws xob, thiab cov kev pabcuam siab - siab.
* ** Qhov tsis zoo:** kim dua, lub sij hawm txhuas ntev dua, thiab muaj kev txwv loj raws li kev tsim khoom.
** ERW Yeeb Nkab (Electric Resistance Welded):**
* **Qhov zoo:** Tus nqi ntau dua- ua tau zoo, muaj nyob rau hauv ntau qhov ntau thiab tsawg, thiab muaj sijhawm ntau lawm. Nws yog qhov tsim nyog rau ntau daim ntawv thov xws li cov kav dej, kev txhawb nqa cov qauv, thiab qis - cov kav dej siab.
* ** Qhov tsis zoo:** Muaj cov welded seam uas tuaj yeem ua qhov taw tes tsis muaj zog yog tias qhov vuam tsis zoo tag nrho. Nws feem ntau tsis tau teev tseg rau qhov tseem ceeb siab - siab lossis kev pabcuam cyclic qhov twg qhov vuam tuaj yeem yog qhov tsis ua haujlwm.
** Lus xaus:** Rau qhov tseem ceeb, siab - siab, lossis siab - cov kev pabcuam kub, ** seamless yeeb nkab yog qhov zoo dua **. Feem ntau, qis-rau- nruab nrab cov ntawv thov siab uas tus nqi yog qhov tseem ceeb, ** ERW yeeb nkab yog qhov kev xaiv zoo tshaj plaws thiab txhim khu kev qha **.
