ASTM A672 Carbon Steel Electrofusion Welded Yeeb Nkab Khoom Taw Qhia
ASTM A672 yog tus qauv tshwj xeeb rau electrofusion welded steel kav rau nruab nrab - kub thiab siab - kev siv siab. Qib qhia txog hom steel phaj siv, thaum qeb qhia txog hom kev kho cua sov ua thaum lub sij hawm tsim cov yeeb nkab. Cov qeb yuav tsum tau qhia seb cov welds puas tau kuaj xyuas hluav taws xob thiab seb cov yeeb nkab puas tau raug kuaj xyuas.

Kev kho cua sov Requirement rau Electrofusion Welded (EFW) Steel Pipes (ASTM A672)
Raws li ASTM A672, tag nrho cov electrofusion welded steel kav yuav tsum tau txais kev kho cua sov tag nrho tom qab vuam thiab tsim, feem ntau siv cov txheej txheem normalizing lossis annealing. Cov txheej txheem tseem ceeb no yog txhawm rau tshem tawm cov kev ntxhov siab uas tshwm sim thaum lub sijhawm vuam thiab ua haujlwm txias, thiab ua kom homogenize cov qauv nplej thiab cov khoom siv kho tshuab ntawm cov vuam, cua sov- cuam tshuam cheeb tsam, thiab cov hlau puag. Qhov no ua kom ntseeg tau tias cov yeeb nkab steel muaj qhov ruaj khov thiab zoo ib yam khoom siv thoob plaws hauv tag nrho cov yeeb nkab lub cev, tsis yog nyob rau hauv qhov chaw vuam, kom ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb nyob rau hauv nruab nrab - kub thiab siab - cov kev mob siab.
