ASTM A691 Tubes

Cov no yog tag nrho cov hluav taws xob fusion welded kav. Lawv muaj cov hlau muab tub lim ntxiv thaum lub sijhawm tsim khoom thiab ua los ntawm cov phaj siab zoo. Yog li ntawd, cov kav dej tuaj yeem siv rau kev siv siab.
Cov npe qib yog CM{{0}}, 1CR, CMS-75, thiab lwm yam. Piv txwv li, A691 Cl22 kav yog nyob rau qib Cl22 thiab yog 1 ¼ CR alloy. Cov kav dej no muaj 9% chromium thiab 1% molybdenum hauv lawv qib 91 muaj pes tsawg leeg thiab hu ua A691 Gr91 EFW steel kav. Lwm qib kuj muaj lawv tus kheej specifications. A691 5cr EFW yeeb nkab muaj 5% chromium thiab 0.5% molybdenum nyob rau hauv nws muaj pes tsawg leeg.
Cov kav dej no tuaj yeem siv rau kev siv sib txawv. Cov kev qhia tshwj xeeb ntawm txhua qib ua rau qib tsim nyog rau kev siv sib txawv. Qee qhov ntawm lawv yog tsim rau kev siv kub; qee qhov tsim nyog rau kev siv siab. Ib txhia ntawm lawv yog siv nyob rau hauv heev corrosive ib puag ncig vim lawv corrosion resistant xwm.
ASTM A691 Alloy Steel EFW Cov Yeeb Nkab kuj tseem siv tau rau kev siv vaj tsev thiab kev tsim qauv. Fabrication muaj normalizing thiab tempering. Qee qib muaj zog los ntawm quenching thiab tempering. Qee qib kuj tuaj yeem tsim los ntawm kev sib xyaw ntawm cov txheej txheem no. Fais Fusion Welded Alloy Steel A691 EFW SAW Pipes muaj zog dua vim cov txheej txheem vuam. Lawv kuj tuaj yeem siv rau hauv cov ntawv thov vuam hnyav. Vim qhov sib txawv muaj pes tsawg leeg, A691 steel kav feem ntau muaj zog dua thiab muaj qhov sib txawv ntawm kev tiv thaiv corrosion.
ASME SA 691 EFW Kab Yeeb Nkab yog ib qho ntawm feem ntau siv ntawm cov hom no. Tus nqi ntawm A691 1 1/4cr Fais Fusion Welded Steel Pipes tuaj yeem sib txawv nyob ntawm seb cov khoom siv hom, txoj kab uas hla, thiab txoj kev tsim khoom.
