Kev Taw Qhia Txog Khoom
ASTM A106 cov yeeb nkab hlau tsis muaj qhov (seamless steel pipe) yog cov yeeb nkab hlau tsis muaj qhov (seamless steel pipe) ua los ntawm cov hlau carbon uas yog American standard. Nws yog ib daim hlau ntev uas muaj ib txoj kab txiav uas tsis muaj qhov thiab tsis muaj qhov sib txuas nyob ib puag ncig. Cov yeeb nkab hlau muaj ib txoj kab txiav uas tsis muaj qhov thiab siv dav ua cov kav dej rau kev thauj cov kua dej, feem ntau nyob rau hauv qhov kub thiab txias thiab siab. ASTM A106 cov yeeb nkab hlau tsis muaj qhov tuaj yeem muab faib ua cov yeeb nkab kub dov, cov yeeb nkab txias dov, cov yeeb nkab kos txias, cov yeeb nkab extruded, thiab lwm yam raws li ntau txoj kev tsim khoom. Cov yeeb nkab kub dov seamless feem ntau yog tsim los ntawm cov khoom siv dov yeeb nkab tsis siv neeg. Lub raj khov kho raug tshuaj xyuas thiab tshem tawm cov qhov tsis zoo ntawm qhov chaw, txiav rau qhov ntev uas xav tau, nyob nruab nrab ntawm lub ntsej muag kawg ntawm lub raj perforation dawb paug, thiab tom qab ntawd xa mus rau lub cub tawg kom sov, thiab perforated ntawm lub tshuab perforation. Thaum lub sijhawm perforation, lub raj txuas ntxiv tig thiab nce mus, thiab nyob rau hauv kev ua haujlwm ntawm lub tshuab dov thiab sab saum toj, ib lub qhov maj mam tsim hauv lub raj puas tsuaj, uas hu ua capillary tube. Tom qab ntawd nws raug xa mus rau lub tshuab dov yeeb nkab tsis siv neeg rau kev dov ntxiv, thiab lub thickness ntawm phab ntsa raug kho kom sib npaug thoob plaws lub tshuab. Lub tshuab ntsuas qhov loj yog siv rau kev ntsuas qhov loj kom ua tau raws li cov qauv. Kev siv lub tshuab dov tas mus li los tsim cov kav dej ASTM A106 uas kub dov yog ib txoj kev siab heev. Cov kav dej ASTM A106 uas tsis muaj qhov loj muaj ntau yam kev siv, feem ntau yog siv ua cov kav dej lossis cov khoom siv rau kev thauj cov kua dej. Ob txoj kev no sib txawv ntawm qhov tseeb, qhov zoo ntawm qhov chaw, qhov loj me me, cov khoom siv kho tshuab, thiab cov qauv me me.

ASTM A106Gr.B seamless steel yeeb nkab yog cov hlau uas tsis muaj carbon ntau uas siv dav dav, uas siv dav hauv kev lag luam roj av, tshuaj lom neeg thiab boiler. Cov khoom siv muaj cov khoom siv kho tshuab zoo. A106-B steel yeeb nkab yog sib npaug rau kuv lub teb chaws 20 steel seamless steel yeeb nkab, thiab siv ASTM A106/A106M cov yeeb nkab kub siab carbon steel seamless steel, qib B. Nws tuaj yeem pom los ntawm ASME B31.3 cov nroj tsuag tshuaj lom neeg thiab cov kav dej roj refinery: A106 cov khoom siv kub ntau: -28.9 ~ 565 ℃.
Cov yeeb nkab hlau tsis muaj seamless ASTM A53, tsim nyog rau cov kav dej siab, cov kav dej thiab cov kav dej dav dav uas muaj qhov kub qis dua 350 ° C.
Cov yeeb nkab hlau tsis muaj qhov sib txuas ASTM A106 rau kev ua haujlwm kub siab, tsim nyog rau qhov kub siab. Sib raug rau lub teb chaws tus qauv No. 20 yeeb nkab hlau.
ASTM yog tus qauv ntawm American Materials Association, uas txawv ntawm txoj kev faib tawm hauv tsev, yog li tsis muaj tus qauv nruj. Muaj ntau yam kev qhia sib txawv ntawm cov khoom nyob rau hauv tib tus qauv, nyob ntawm koj qhov kev siv tshwj xeeb.
ASTM A106 cov yeeb nkab hlau tsis muaj seamless muaj ob txoj kev ua: kos duab txias thiab dov kub. Ntxiv rau cov txheej txheem tsim khoom sib txawv, ob qho tib si sib txawv hauv qhov tseeb, qhov zoo ntawm qhov chaw, qhov loj me me, cov khoom siv kho tshuab, thiab cov qauv kev teeb tsa. Nws yog siv dav hauv ntau yam lag luam xws li roj av, kev lag luam tshuaj lom neeg, boilers, chaw tsim hluav taws xob, nkoj, kev tsim tshuab, tsheb, kev tsav dav hlau, aerospace, lub zog, geology, kev tsim kho, thiab kev lag luam tub rog.
