ASTM A135 Hluav Taws Xob Resistance Welded (ERW) yeeb nkab
Lub ntsiab lus tseem ceeb
Standard specification rauhluav taws xob-kuj-welded steel yeeb nkabnpaj ua ntej raumechanical thiab low -pressure fluid conveyance applications. Nws yog ib tug ncaj competitor rauASTM A53 Hom Ethiab yog siv rau cov hom phiaj zoo sib xws.
Qhov tseem ceeb Distinction:A135 npogTsuas yog welded yeeb nkab(ERW). Nws uatsis yognpog seamless yeeb nkab (tsis zoo li A53 uas npog ob qho tib si).

Critical Technical & Selection Notes
1. Qhov "Functional Equivalent" rau A53 ERW
Rau txhua lub hom phiaj siv tau:
A135 Qib B = A53 Qib B, Hom E (ERW)
Lawv yogsib pauv taunyob rau hauv cov nqe lus ntawm chemistry, lub zog, thiab feem ntau siv.
Qhov kev xaiv feem ntau los rauzeb muaj peev xwm, distributor Tshuag, los yog qhov project specification.
2. Thaum twg Koj Yuav Qhia A135 Tshaj A53?
Qhia rau A135 thaum:
Qhov projectkom meej meej xav tau ERW-tsuas yog cov yeeb nkab(tsis muaj kev xaiv seamless xav tau).
Ib tus neeg muag khoom tshwj xeeb lossis zeb tshwj xeeb hauv A135 ntau lawm.
Nws raug hu tawm hauv qee yamkev siv hluav taws xob, lub nroog, lossis cov qauv kev qhia tshwj xeeb.
3. Kev txwv (Tib yam li A53 ERW)
Tsis yog rau siab -kev pabcuam kub (>~ 400℃F / 204 degree).
Tsis yog rau siab - siab los yog cov txheej txheem tseem ceeb piping.
Weld seam kev ncaj nceesyog qhov tseem ceeb - xav tau kev tsim khoom zoo.
Txoj cai txwv siv tau (feem ntauQeb D Fluid Servicehauv ASME B31.3).
4. Fabrication & Koom
Ua tauthreaded, welded, los yog grooved.
Galvanized versionsmuaj ntau heev rau kev tiv thaiv corrosion sab nraum zoov.
Vuam galvanized yeeb nkab yuav tsum tau ntsuas kev nyab xeeb rau zinc fumes.
Cov ntsiab lus ntawm kev lag luam: Vim li cas Ob Qhov Kev Ntsuas Zoo?
Keeb Kwm & Kev Lag Luam Vim Li Cas:
Mill Specialization:Qee cov yeeb nkab mills keeb kwm tau tsim lawv cov tshuab zoo thiab cov ntawv pov thawj nyob ib puag ncigA135raws li lawv tus qauv khoom tseem ceeb.
Supply Chain Simplicity:Rau distributors uas tsuas yog muag welded yeeb nkab (tsis muaj seamless), specificationsA135ua kom pom tseeb tias seamless tsis yog kev xaiv lossis hloov pauv.
Specifier Preference:Qee lub tuam txhab engineering lossis cov khoom siv hluav taws xob muaj keeb kwm tshwj xeeb uas hu rauA135.
Kev yuav khoom tiag:Hauv kev ua lag luam, A135 thiab A53 ERW feem ntau raug kho raws likev lag luam sib npaug. Tus neeg xa khoom tuaj yeem ua tiav qhov kev txiav txim rau "A53 Gr.B ERW" nrog cov yeeb nkab uas tsim los rau A135 tus qauv, raws li nws ua tau raws li txhua yam kev cai.
Key Takeaway: Txoj Cai Yooj Yim
Rau qhov dav -lub hom phiaj, qis- siab welded steel yeeb nkab:
Yog koj pomA135- koj tau txaisERW cev.
Yog koj pomA53-kojyuav tsum kuaj HOM(Hom E=ERW, Hom S=Seamless).
A135 Qib BthiabA53 Qib B Hom Eyogfunctionally tib yam khoom.
Lus Cim Kawg: ASTM A 135yog awelded-tsuas yog cov yeeb nkab txheemuas ua rau cov yeeb nkab zoo tib yam hauv kev ua haujlwm rauASTM A53 Hom E. Nws yog tus nqi -kev xaiv zoo rautsis yog -tseem ceeb txhua yam, cov qauv, thiab qis- cov ntaub ntawv siv dej siab. Rau ib qho tseem ceeb lossis siab -kev pabcuam kub / siab, tsis yog A135 lossis A53 ERW tsis haum - koj xav tauseamless yeeb nkab (A106, A333, thiab lwm yam).
