Hom E steel yeeb nkabyog tsim nyob rau hauv raws liASTM A53thiab yog tsim los ntawm Electric-Resistance-Vuam (ERW) txheej txheem.
Cov yeeb nkab no feem ntau yog siv rau kev siv tshuab thiab kev siv siab tab sis kuj tsim nyog siv los ua cov kav dej dav dav rau kev thauj mus los ntawm chav dej, dej, roj, thiab huab cua.
Qhov luaj li cas ntawmASYM A53 yog DN 6-650.
Qhov ntau lawm ntawmHom E yog DN 20-650 DN.
Cov yeeb nkab diameters hauv qab DN 20 tsawg dhau rau Hom E. Rau cov laj thawj kev ua haujlwm tsis muaj txoj hauv kev los tsim lawv, yog li Hom S, uas yog ib qhoseamless manufacturing txheej txheem, yog feem ntau siv.
Kev tsim cov txheej txheem rau ASTM A53 Hom E
Cov txheej txheem ntau lawm suav nrog kev tsim cov hlau coils los ntawm yob, vuam npoo los ntawm cov cua kub tsis kam, deburring welds, thiab sizing thiab straightening los ua cov raj.
Cov yam ntxwv ntawm ASTM A53 Hom E Hlau Yeeb Nkab
Nws muaj ob longitudinal taub qab welds sab hauv thiab sab nraud.Cov npoo ntawm cov hlau phaj yog welded rau ob sab hauv thiab sab nraud ntawm cov yeeb nkab thaum lub sij hawm tsim cov txheej txheem los xyuas kom meej lub zog thiab sealing.
Sab hauv thiab sab nrauv welds tsis pom.Cov welds sab hauv thiab sab nraud raug ntxuav kom txog qhov siab tib yam li cov yeeb nkab nto thaum lub sij hawm tsim khoom, uas ua rau tag nrho cov tsos thiab ua tau hydrodynamic zog ntawm cov yeeb nkab.
ASTM A53 Hom E Cov Khoom Siv Tshuaj
Rau txhua qhov kev txo qis ntawm 0.01% qis dua cov pa roj carbon siab tshaj plaws, qhov nce ntawm 0.06% ntawm manganese saum toj no qhov siab tshaj plaws yuav raug tso cai mus txog qhov siab tshaj ntawm 1.65%.
Cu, Ni, Cr, Mo, thiab V, yog tsib yam ua ke tsis pub tshaj 1.00%.
