1. "C90" txhais li cas?
Lub npe "C90" tsis yog qib tshuaj universal zoo li A106 lossis A53. Hloov chaw, nws feem ntau yog hais txog aqhov ntsuas qhov ntsuasteem los ntawmAmerican Society for Testing thiab Materials (ASTM).
ASTM C90 Khoom:Cov qauv no yog lub npe hu ua"Standard Specification for Load-Bearing Concrete Masonry Units". Thaum xub thawj siab ib muag, qhov no zoo li tsis cuam tshuam rau cov yeeb nkab steel. Qhov kev sib txuas yog tias C90 qhia txog qhov yuav tsum tau muaj rau cov kab noj hniav hollow hauv cov pob zeb.
Lub luag haujlwm ntawm Pipe:A "C90 Seamless Steel Pipe" yog ibsteel yeeb nkab tsim los rau cov txheej txheem meej uas haum txig rau hauv cov tub ntxhais ntawm tus qauv C90 qhob thaiv.Nws lub ntsiab siv yog raws li ib tugvoid qublos yoglub tes tsho.
Hauv qhov tseeb, "C90" piav txog cov yeeb nkablub hom phiaj thiab qhov loj me, tsis yog nws cov khoom muaj pes tsawg leeg. Cov khoom siv specs yog los ntawm lwm cov qauv, uas peb yuav hais txog tom ntej.
2. Cov yam ntxwv tseem ceeb thiab cov lus qhia tshwj xeeb
Thaum qhov loj me yog txhais los ntawm ASTM C90, cov yeeb nkab nws tus kheej tau ua rau lwm cov qauv uas txhais tau tias nws cov qib steel thiab cov txheej txheem tsim khoom.
Kev tsim khoom: Seamlesstxhais tau hais tias cov yeeb nkab yog tsim los ntawm cov khoom cylindrical steel billet uas yog cua sov thiab tho los ntawm qhov chaw. Qhov no tsim ib cov yeeb nkab uas tsis muaj welded seams, ua rau nws muaj zog thiab txhim khu kev qha nyob rau hauv siab thiab load tshaj welded lwm txoj.
Common Material Standard:Cov khoom siv feem ntau siv rau cov kav dej C90 yogASTM A513 Cov Lus Qhia Tshwj Xeeb. Cov qauv no suav nrog carbon thiab alloy steel hluav taws xob tiv thaiv welded (ERW) thiabseamlessmechanical tubing. Rau C90 daim ntawv thov, hom seamless yog teev rau nws lub zog.
Steel Qib:Lawv feem ntau yog ua los ntawmQib 1020los yogQib 1026steel, uas yog tsawg- carbon steels paub txog lub zog zoo, formability, thiab weldability.
Loj:Tus txheej txheem sab nraud (OD) rau C90 yeeb nkab yog3-5/8 nti.
Phab ntsa Thickness:Common phab ntsa thicknesses muaj xws li:
Teem caij 40(kwv yees . 0.216" phab ntsa)
Teem caij 80(kwv yees . 0.300" phab ntsa)
Qhov kev xaiv nyob ntawm tus qauv thauj khoom nws xav tau los txhawb nqa.
3. Cov ntawv thov thiab kev siv tseem ceeb
C90 seamless steel yeeb nkab yog ib yam khoom tshwj xeeb uas siv yuav luag tshwj xeeb hauv kev tsim kho kom huv si, ntxiv qhov qhib rau hauv cov pob zeb ua vaj tse.
Hluav taws xob Conduit Sleeves:Feem ntau siv. Cov yeeb nkab yog muab tso rau hauv kab rov tav los ntawm cov hollow cores ntawm cov pob zeb ua ntej ua phab ntsa. Cov hluav taws xob tom qab khiav cov kav dej lossis cov cables los ntawm cov khoom ua ntej no - lub tes tsho tsim, txuag lub sijhawm thiab kev ua haujlwm loj piv rau qhov drilling lossis chiseling tom qab kev tsim kho.
Cov kav dej Penetrations:Siv zoo sib xws rau cov kav dej, cov kav dej, lossis lwm yam kev pab cuam los ntawm cov phab ntsa masonry.
Structural reinforcing:Qee zaum, cov yeeb nkab tuaj yeem raug grouted nyob rau hauv qhov chaw thiab ua raws li cov txheej txheem, muab kev txhawb nqa ntxiv, txawm tias qhov no tsis tshua muaj.
Cov txiaj ntsig ntawm Kev Siv C90 Seamless Pipes:
Txuag Sijhawm & Ua Haujlwm:Tshem tawm qhov xav tau rau cov tub ntxhais drilling.
Ntxuav & Precise Qhib:Tsim ib lub qhov zoo meej, puag ncig.
Structure Integrity:Tsis cuam tshuam lub vev xaib ntawm cov pob zeb ua pob zeb zoo li drilling tau.
Durable:Seamless kev tsim kho thiab cov khoom siv carbon steel tiv thaiv kev puas tsuaj thaum siv.
4. C90 vs. Lwm cov kav dej
Nws yog ib qho tseem ceeb kom paub qhov txawv C90 los ntawm lwm hom yeeb nkab uas nws feem ntau tsis meej pem nrog.
