Cov Scope ntawm ASTM A106 thiab ASTM A53:
ASTM A53 specification npog cov yeeb nkab steel tsim hom seamless thiab welded, cov khoom hauv carbon steel, dub hlau.Nto ntuj, dub, thiab kub-dipped galvanized, zinc coated steel yeeb nkab.Txoj kab uas hla ntawm NPS 1⁄8 txog NPS 26 (10.3mm txog 660mm), nominal phab ntsa thickness.
ASTM A106 tus qauv specification npog covcarbon seamless steel yeeb nkab, thov rau cov kev pabcuam kub kub.
Ntau hom thiab qib rau ob tus qauv:
Rau ASTM A53 muaj ERW thiab seamless steel kav Hom F, E, S npog qib A thiab B.
A53 Hom F, rauv taub qab welded, nruam weld Qib A
A53 Hom E, Hluav taws xob tiv thaiv welded (ERW), Qib A thiab Qib B.
A53 Hom S, Seamless steel yeeb nkab, hauv Qib A thiab Qib B.
Yog tias cov khoom siv raw steel ntawm cov qib sib txawv hauv cov txheej txheem ntawm kev nruam nruam, cov ntaub ntawv hloov pauv yuav tsum raug txheeb xyuas.Thiab cov chaw tsim khoom yuav tsum tshem tawm cov khoom hloov pauv nrog cov txheej txheem uas tuaj yeem cais cov qib zoo.
Nyob rau hauv cov ntaub ntawv ASTM A53 Qib B hauv ERW (hluav taws xob tsis kam welded) yeeb nkab, vuam seam yuav tsum tau ua cov kev kho cua sov nrog qhov tsawg kawg nkaus 1000 ° F [540 ° C].Nyob rau hauv no txoj kev tsis muaj untempered martensite nyob.
Nyob rau hauv rooj plaub ASTM A53 B yeeb nkab nyob rau hauv txias nthuav, ces expansion yuav tsum tsis txhob ntau tshaj 1.5% ntawm qhov yuav tsum tau OD.
Rau ASTM A106 steel yeeb nkab, kev tsim hom tsuas yog nyob rau hauv seamless, txheej txheem kub dov thiab txias kos.Qib A, B thiab C.
ASTM A106 Qib A: Cov pa roj carbon ntau tshaj 0.25%, Mn 0.27-0.93%.Tsawg tensile lub zog 48000 Psi lossis 330 Mpa, yield zog 30000 Psi lossis 205 Mpa.
A106 Qib B: Qhov siab C siab tshaj 0.30%, Mn 0.29-1.06%.Tsawg tensile lub zog 60000 Psi lossis 415 Mpa, yield zog 35000 Psi lossis 240 Mpa.
Qib C: siab tshaj C 0.35%, Mn 0.29-1.06%.Lub zog tensile yam tsawg 70000 Psi lossis 485 Mpa, yield zog 40000 Psi lossis 275 Mpa.
Txawv nrogASTM A53 GR.B seamless steel kav,ASTM A106 GR.B seamless steel kavmuaj Si min 0.1%, uas A53 B muaj 0, yog li A106 B muaj cov cua sov zoo dua li A53 B, txij li Si txhim kho cov cua sov.
Kev siv thaj chaw ntawm ob qho tib si:
Ob lub kav dej siv rau kev siv tshuab thiab kev siv tshuab, thauj chav, dej, roj, thiab lwm yam.
ASTM A53 Tube Daim Ntawv Thov:
1. Kev tsim kho, kev thauj mus los hauv av, tshem tawm cov dej hauv av thaum lub tsev, chav dej thauj mus los thiab lwm yam.
2. Bearing poob lawm, machinery qhov chaw ua.
3. Daim ntawv thov hluav taws xob: Kev xa hluav taws xob, kev siv hluav taws xob tsim hluav taws xob tsim hluav taws xob.
4. Cua fais fab nroj tsuag anti-static raj thiab lwm yam.
5. Cov kav dej uas xav tau zinc coated.
ASTM A106 Tube Daim Ntawv Thov:
Tshwj xeeb tshaj yog rau cov kev pabcuam kub siab txog li 750 ° F, thiab nws tuaj yeem hloov ASTM A53 yeeb nkab rau feem ntau.Hauv qee lub tebchaws tsawg kawg hauv Tebchaws Meskas, feem ntau ASTM A53 yog rau welded yeeb nkab thaum ASTM A106 yog rau seamless steel kav.Thiab yog tias tus neeg thov rau ASTM A53 lawv tseem yuav muab ASTM A106.Hauv Suav teb, cov chaw tsim khoom yuav muab cov yeeb nkab uas ua raws li peb tus qauv ASTM A53 GR.B/ASTM A106 GR.B/API 5L GR.B seamless steel kav.
