ASTM A53 yog tus qauv specification rau seamless thiab welded dub thiab kub-dipped galvanized steel yeeb nkab uas yog npaj rau siv nyob rau hauv mechanical thiab siab daim ntaub ntawv. ERW (hluav taws xob tsis kam vuam) yog cov txheej txheem tsim khoom rau cov yeeb nkab uas cuam tshuam nrog kev tsim cov hlau txuas txuas ntxiv mus rau hauv cov duab cylindrical thiab tom qab ntawd vuam cov seams ua ke siv hluav taws xob tiv thaiv.
ASTM A53 ERW welded steel kav yog tsim los ntawm cov hlau zoo thiab feem ntau siv rau ntau yam kev lag luam xws likev tsim kho, kav dej, thiab kev thauj mus los roj & roj. ERW welded steel kav yog nyiam dua cov kav dej seamless rau qee qhov kev siv vim lawv cov nqi qis thiab yooj yim ntawm kev tsim khoom.
ASTM A53 ERW welded steel kav muaj ntau yamqib A, B, thiab Cuas txawv raws li lawv cov tshuaj muaj pes tsawg leeg thiab mechanical zog. Qib A yog qib qis tshaj thiab qis tshaj thaum qib C yog qib siab tshaj thiab muaj zog tshaj plaws. Cov qib feem ntau siv hauv kev lag luam yog qib B.
ASTM A53 ERW welded steel kav muaj nyob rau hauv ntau qhov sib txawv thiab phab ntsa thicknesses. Lawv tuaj yeem raug kho kom haum raws li cov kev thov tshwj xeeb. Cov kav dej no feem ntau yog muab rau hauv cov xim dub lossis kub-dipped galvanized tiav, nrog rau lwm cov tiav tiav thaum thov.
Zuag qhia tag nrho, ASTM A53 ERW welded steel kav muaj kev txhim khu kev qha thiab raug nqi zoo rau ntau yam kev siv hauv kev lag luam.
