Qauv Tom Qab
ASTM A106 yog kev qhia tshwj xeeb los ntawm Asmeskas haiv neeg rau kev sim thiab cov ntaub ntawv (Astm) rau Seamless cov pa roj hlau steel hlau tsim rau high- kub kev pab. Nws yog dav siv nyob rau hauv cov kav dej thauj high- kev nqus dej (xws li cov roj, thiab roj av, thiab cov ntawv thov hluav taws xob, thiab kev siv hluav taws xob, thiab kev siv hluav taws xob, thiab kev siv hluav taws xob.
Gr B yog cov qhab nia feem ntau hauv cov qauv no, cais tawm cov roj carbon hlau siab ua piv rau ASTM A53 Gr B.

Muaj zog
Weldability: Compatible with common welding methods (eg, SMAW, GTAW), but preheating (for thick-walled pipes) and post-weld heat treatment may be required to prevent cracking.
Formancion: tuaj yeem txias / kub bent lossis flared, tab sis ua haujlwm txias txias yuav ua rau ua haujlwm hnyav, yuav tsum muaj kev ua haujlwm tawv tawv.
Corrosion Kuj
Cov khoom ua pov thawj qog corrosion tsis kam nyob rau hauv nruab ib puag ncig ib puag ncig (piv txwv li, cua qhuav, dej huv si) tab sis yog nquag mus rau hauv cov huab cua noo lossis xeb. Anti - corrosion ntsuas (piv txwv li, txheej, galvanizing rau ib puag ncig hnyav.
Ntau Lawm Flow
Kev npaj nyiaj Billet: siab {- zoo carbon steel sib tw beets (piv txwv li ntawm Tuam Tshoj tus 20 # steel) yog rhuab rau cov yas deformation.
Tho: Daim phiaj zeb tho hloov cov nyiaj txiag rau hauv lub hollow manrel (siv tsis siv neeg lossis txuas ntxiv rolling mills).
Tube Dov: Ntau tus dov hla dhau cov phab ntsa thickness thiab loj tus yeeb nkab kom haum qhov ntev.
Kev kho cua sov: ua haujlwm ib txwm los yog anealing yog ua los ua kom ua kom zoo dua microstructure thiab ua kom zoo dua cov khoom siv neeg kho tshuab.
Cov kev kho deg: Deburring, Oxide nplai tshem tawm, thiab kev kuaj kom nruj / pom tau.
Loj npaum li cas
Sab Nrauv Inch: 1/8 "(3.35mm) txog 48" (1219.2mm)
Phab ntsa tuab: Cov qib nyiam SCH 40, Sch 80, thiab XXS, nrog cov tuab tuab sib txuas los ntawm txoj kab uas hla thiab siab.
4. Daim Ntawv Thov Kev Sau Npe
Kev lag luam fais fab: High - h siab siab chav dej pipelines, boiler Thaib teb.
Petrochemical Kev Lag Luam: Kev Hloov Pauv Cov Kav Dej, Nruab Nrab - Cov roj (roj thauj.
Kev tsim khoom lag luam: Cov hlab ntsha siab, kev sib pauv cua sov, thiab kev siab dav {{}} sov tshuab raj.
Marine Engineering: Lub cav chav tsev xa khoom thiab dej hiav txwv - tsis tiv thaiv (nrog kev tiv thaiv corrosion).
Kev Xeem Sijhawm
Tshuaj Ntsuam Xyuas Tshuaj: Ua kom pom tseeb cov khoom siv theem pib ua raws li ASTM A106 cov tseev kom muaj.
Kev Ntsuas Mechanical: Tensile cov ntawv xeem, cov kev ntsuam xyuas dav, thiab cov tshuaj tua hluav taws kom kuaj tau lub zog thiab kev sib tw.
Tsis - Kev sim tshuaj (ndt):
Kev sim ultrasonic (U) rau sab hauv kev tsis zoo.
Sib nqus partle kuaj (mt) rau saum npoo / ze - npoo npoo.
Hydrostatic Kuaj: Txhua cov yeeb nkab undergoes lub siab ntsuas (feem ntau txog 2000 psi lossis raws li tau teev tseg) kom ntseeg tau tias xau.
Cov Kev Tshwj Xeeb
Kev xaiv cov kev ntsuas: Tsawg {{{{{{{0} Kev Ntsuas Kub Kub (piv txwv li Kev Ntsuas Kub (} I} ITCH Degree) thiab cov txheej txheem Weld tsim nyog rau cov ntawv thov tseem ceeb.
