ASTM A106 Seamless Yeeb Nkab yog dab tsi?

ASTM A106 txhaiscov yeeb nkab carbon seamlessrau kev pabcuam kub siab. Tsis zoo li cov kav dej welded, cov no yog tsim los ntawm cov khoom khov kho los ntawmCov txheej txheem kub tho, dov, thiab ua tiav, xyuas kom meej tias muaj cov qauv sib xws yam tsis muaj weld seams.

Cov txiaj ntsig tseem ceeb ntawmASTM A106 seamless yeeb nkab:

  • Cov qauv sib xws tsis muaj cov seams weld
  • Kev tiv thaiv kub siab
  • Lub zog tensile thiab yield zoo heev
  • Haum rau kev khoov, flanging, thiab vuam

Cov yam ntxwv no ua rauASTM A106 cov kav dejzoo tagnrho raucov chaw tsim hluav taws xob, cov chaw tsim tshuaj petrochemical, cov chaw ua roj refinery, boilers, thiab cov tshuab raj xa dej siab.

ASTM A106 Qib

Cov kav dej ASTM A106 muaj peb qib:Qib A, Qib B, thiab Qib CTxhua qib muaj cov khoom siv tshuaj lom neeg thiab cov khoom siv kho tshuab rau ntau yam kev pabcuam sib txawv.

Qib Cov pa roj carbon ntau tshaj plaws (C) Manganese (Mn) Lub Zog Tawm (MPa) Lub zog Tensile (MPa) Daim Ntawv Thov Ib Txwm Muaj
A 0.25% 0.27–0.93% ≥ 205 ≥ 330 Cov kav dej uas tsis muaj zog, thiab kub tsawg dua
B 0.30% 0.29–1.06% ≥ 240 ≥ 415 Feem ntau, kev pabcuam kub siab dav dav
C 0.35% 0.29–1.06% ≥ 275 ≥ 485 Kub thiab txias heev, muaj kev nyuaj siab, thiab tej chaw nyuaj heev

Qhov Loj thiab Qhov Loj

Cov kav dej ASTM A106 muaj ntau yam loj me ntawm cov kav dej (NPS) txij li 1/8” txog 48”, nrog rau phab ntsa tuab raws li ASME B36.10M cov sijhawm, xws li SCH40 (STD), SCH80 (XH), SCH160.

Cov kab uas me me (< 1½”) tej zaum yuav ua tiav los ntawm kev kub lossis rub txias

Cov kab uas loj dua (≥ 2”) feem ntau yog kub-ua tiav

Qhov ntev feem ntau yog 6-12 meters lossis kho raws li qhov xav tau ntawm qhov project

Cov Khoom Siv Kho Tshuab

Cov kav dej ASTM A106 yog tsim los rau kev siv kub siab, muab:

Lub zog tensile thiab yield siab

Kev ruaj khov zoo heev

Zoo ductility thiab weldability

Kev kuaj xyuas kev cuam tshuam xaiv tau rau cov xwm txheej hnyav

Qib Lub Zog Tawm (MPa) Lub zog Tensile (MPa) Kev ntev (%)
A ≥ 205 ≥ 330 ≥ 30
B ≥ 240 ≥ 415 ≥ 30
C ≥ 275 ≥ 485 ≥ 25

 

Cov Ntawv Thov Feem Ntau

ASTM A106 seamless yeeb nkabsiv dav thoob plaws hauv kev lag luam, suav nrog:

Cov Chaw Fais Fab: Cov kav dej ua pa, cov boilers, cov khoom hloov pauv cua sov

Petrochemical & Refinery: Cov kav dej tshuaj lom neeg kub thiab siab

Roj & Roj: Cov kav dej thauj roj thiab roj av

Kev Lag Luam: Cov nroj tsuag tshuaj, kev tsim nkoj, cov hlab ntsha siab, cov kav dej lag luam

Lawv lub peev xwm los tiv taus qhov kub thiab txias, siab siab, thiab qhov chaw corrosive ua rau lawv yog qhov kev xaiv zoo tshaj plaws hauv cov haujlwm engineering thoob ntiaj teb.

Vim li cas ho xaiv ASTM A106 Seamless Pipes?

Kev tsim kho tsis muaj qhov sib txuasua kom muaj kev nyab xeeb thiab kev ntseeg siab hauv cov tshuab siab

Ntau qib(A/B/C) tso cai rau kev ua kom muaj zog thiab kub raws li qhov xav tau

Ntau qhov loj menpog cov kab uas me mus rau cov kab uas loj heev

Kev lees paub tus qauv thoob ntiaj tebua kom muaj kev sib raug zoo nrog cov cai engineering thoob ntiaj teb

Cov Kev Xav Tseem Ceeb

Kev Xaiv QibQib B yog qhov feem ntau, thaum Qib C yog rau kev siv siab / kub siab.

Cov Yeeb Nkab Teem CaijXaiv raws li qhov yuav tsum tau ua ntawm lub siab, qhov kub thiab txias, thiab qhov ntws.

Cov Kev Cai Ua Haujlwm: Paub meej tias nws tsim nyog rau kev khoov, vuam, lossis lwm yam kev ua haujlwm.

Kev Ua Raws CaiXyuas kom meej tias daim ntawv pov thawj ASTM lossis ASME SA106 rau cov kab ke uas muaj kev kub ntxhov.

Xaus lus

ASTM A106 cov yeeb nkab carbon seamlessyog cov kev daws teeb meem txhim khu kev qha, siv tau ntau yam, thiab ua tau zoo rau kev siv kub thiab siab. Kev xaiv qib, qhov loj me, thiab phab ntsa tuab kom ua rau muaj kev nyab xeeb zoo tshaj plaws, ua haujlwm tau zoo, thiab lub neej ntev hauv cov chaw tsim hluav taws xob, cov chaw ua roj, cov chaw tsim roj av, thiab cov kav dej lag luam.
