SSAW yeeb nkab ASTM A53

ASTM A53 yog cov txheej txheem rau cov yeeb nkab, cov hlau, dub thiab kub dipped, zinc coated, welded thiab seamless. Qhov kev qhia no npog seamless thiab welded dub thiab kub dipped galvanized steel yeeb nkab. Cov lus qhia no yog siv cov hom nram qab no thiab cov qib: 1 Hom F-Rauv-taub qab-pob zeb, nruam ...

ASTM A53 yog cov txheej txheem rau cov yeeb nkab, cov hlau, dub thiab kub dipped, zinc coated, welded thiab seamless. Qhov kev qhia no npog seamless thiab welded dub thiab kub dipped galvanized steel yeeb nkab.


Qhov kev qhia ua raws li cov nram qab no:
1 Hom F-Rauv-taub qab-pob tw, nruam txuas ntxiv Qib A.
2 Hom E-Electric-resistance-welded, Qib A thiab B,
3 Hom S-Seamless, Qib A thiab B.


Nco Ntsoov:
Hom F tsis yog npaj rau flanging.
Yog hais tias Hom S lossis Hom E yuav tsum tau muaj kev sib txeeb los yog txias thooj, Qib A yog qib qib dua; txawm li cas los xij, qhov no tsis yog npaj los txwv qhov txias txias ntawm Qib B kav.
Hom E yog muab los tsis yog nthuav lossis txias dua ntawm qhov kev xaiv ntawm lub khw.


ASTM A53 yeeb nkab (tseem raug xa mus rau ASME SA53 yeeb nkab) yog rau cov khoom siv dag zog thiab kev siv siab thiab tseem siv tau rau kev siv tibsi hauv cov kav dej, dej, roj thiab cua. Nws yog tsim rau kev siv welding thiab kev ua haujlwm ua haujlwm nrog coiling, bending, thiab flanging, raws li kev tsim nyog.


Kuv lub tuam txhab kev lag luam raug hloov siab tshaj plaws kev siv tshuab kev vuam voog, uas yog ob kauj ruam kev ua tiav. Cov kav dej yog xub ua rau hauv cov yeeb nkab thiab lub nrig tack-welded ntawm kev kub ceev. Hauv qhov thib ob cov kauj ruam ntawm cov kav dej ces tom qab thaum kawg tau muab khi rau cov hlua khi thiab muab cov hlua khi zoo dua qub nrog rau lwm cov qauv SAWH. Cov txheej txheem no yuav tshem tawm cov teeb meem ntawm kev sib tsoo ntawm cov hlua khib nyiab thaum lub yeeb nkab txhuam thiab cov kis tau rau sab hauv. Nws kuj pab kom muaj kev ruaj ntseg ntawm cov pob qij txha thiab cov khoom tsim tau. Cov khoom no yog siv rau hauv cov roj hauv cov roj thiab cov yeeb nkab.
