Taw qhia ntawm ASTM A53
ASTM A53 (tseem hu ua ASME SA53 yeeb nkab) yog cov pa roj carbon steel hlau, uas tuaj yeem siv los ua cov qauv hlau lossis cov kav dej tsis tshua muaj siab thiab tseem siv tau rau kev siv tib yam hauv chav dej, dej, roj thiab cua. yog tsim los ntawm ASTM International hauv cov lus qhia ASTM A53 / A53M.
ASTM A53 steel yeeb nkab specifications
A53 yeeb nkab los ntawm peb hom (F, E, S) thiab ob qib (A, B).
A53 Hom F yog tsim los nrog lub qhov cub tawg vuam lossis tej zaum yuav muaj qhov txuas txuas ntxiv (Qib A nkaus xwb)
A53 Hom E muaj hluav taws xob tsis kam vuam (Qib A thiab B)
A53 Hom S yog cov yeeb nkab seamless thiab pom hauv Qib A thiab B)
A53 Qib B Seamless yog peb cov khoom lag luam ntau tshaj plaws nyob rau hauv cov lus qhia no thiab A53 yeeb nkab feem ntau tau lees paub dual rauA106 BSeamless yeeb nkab.
Cov yeeb nkab xaj raws li qhov tshwj xeeb no yog npaj rau kev siv tshuab thiab kev siv siab thiab kuj tseem siv tau rau kev siv tib yam hauv chav dej, dej, roj, thiab cua kab. Nws yog tsim rau vuam, thiab tsim nyog rau kev ua hauj lwm uas muaj xws li coiling, dabtsi yog khoov, thiab flanging, raws li cov kev tsim nyog hauv qab no:
1. Hom F tsis yog tsim rau flanging.
2.Thaum Hom S thiab E yuav tsum muaj rau kev sib txuas sib txuas lossis txias dabtsi yog khoov, Qib A yog qib siab dua. Cov kev cai no tsis yog los txwv tsis pub txias khoov ntawm Qib B yeeb nkab.
3.Type E yog cov rooj tog tsis muaj kev nthuav dav lossis txias nthuav dav ntawm qhov kev xaiv ntawm cov chaw tsim khoom.
Scope
ASTM A53 yeeb nkab npog Seamless thiab Welded, Dub thiab Kub-Dipped Galvanized nominal (nruab nrab) phab ntsa yeeb nkab rau coiling, dabtsi yog khoov, flanging thiab lwm yam tshwj xeeb lub hom phiaj thiab yog haum rau vuam. Nruam-Welded yeeb nkab tsis yog tsim rau flanging. Lub hom phiaj rau qhov twg cov yeeb nkab yog npaj yuav tsum tau teev nyob rau hauv kev txiav txim.
Nco tseg: Tag nrho cov khoom xyaw rau tsib lub ntsiab lus no yuav tsum tsis pub tshaj 1.00 feem pua .
Mechanical Properties sib piv
Nco tseg: Qhov no yog cov ntaub ntawv sau los ntawm ASME Specification A53. Thov xa mus rau tus qauv tshwj xeeb lossis Specification lossis tiv tauj peb kom paub meej ntxiv.
Cov txheej txheem ntau lawm ntawm ASTM A53
Seamless steel yeeb nkabkev tsim khoom yog muab faib ua cov yeeb nkab kub-kuav los tiag thiab txias seamless yeeb nkab.
1.Production txheej txheem ntawm kub dov seamless steel yeeb nkab: raj billet → cua sov → perforation → peb-cov menyuam / cross-rolling & nruam dov → de-pipe → sizing → txias → straightening → hydraulic kuaj → cim → seamless steel yeeb nkab nrog leverage Nthuav cov nyhuv.
2. Cov txheej txheem tsim khoom ntawm cov tub ntxhais txias txias seamless steel raj: raj blank → cua sov → perforation → taub hau → annealing → pickling → oiling → ntau qhov txias txias → blank raj → heat treatment → straightening → hydraulic test → marking → storage.
Lub tswv yim: Seamless yeeb nkab feem ntau yog tsim los ntawm kev kos duab zoo tshaj lub mandrel los tsim kev teeb tsa ntawm lub raj. Welded yeeb nkab feem ntau yog ua los ntawm dov ib lub tiaj tiaj ntawm cov khoom siv rau hauv ib lub raj thiab koom nrog cov npoo ua ke nrog cov kav ntev. Lub vuam tuaj yeem ua tau los ntawm Kev Siv Hluav Taws Xob Hluav Taws Xob (Hom E) lossis los ntawm qhov cub Butt Welded / Nruam Vuam (Hom F).
Daim ntawv thov ntawm ASTM A53
1.Kev tsim kho: cov kav dej hauv qab, cov dej hauv av, thiab kev thauj mus los ntawm cov dej kub.
2.Mechanical processing, bearing sleeves, processing machinery parts, thiab lwm yam.
3. Hluav taws xob: Gas xa, Hydroelectric zog kua kav dej
4.Anti-static raj rau cua fais fab nroj tsuag, thiab lwm yam.
