ASME B 36. 10 muaj cov ntsiab lus qhia ntxiv txog cov yeeb nkab. Cov qauv kev lag luam rau cov yeeb nkab loj kuj txawv ntawm ntau hom yeeb nkab. Rau tus qauv pas, ib 4. 5 " OD cov yeeb nkab yuav raug xa mus ua 4" NPS txawm li cas los xij rau txoj kab yeeb thiab OCTG, nws yuav raug xa mus raws li 4. 5 " xwb. Phab ntsa tuab tseem hais tau txawv. Rau cov yeeb nkab txheem, cov sij hawm ntsuas yeeb yog siv los tsim cov phab ntsa tuab. Txawm li cas los xij cov kab yeeb nkab yuav luag ib txwm xa los ntawm phab ntsa tuab hos OCTG xa los ntawm qhov hnyav ib txhais taw.
Nyhav ntawm Yeeb Nkab
Kev hnyav ntawm cov yeeb nkab yog ntsuas hauv phaus ib txhais taw lossis kilus hauv ib lub ntsuas. Ib qho yuav tsum nco ntsoov tias qhov nyhav ntawm cov yeeb nkab hauv cov ansi yeeb nkab loj daim ntawv yog" thevical" qhov hnyav thiab tsis yog qhov hnyav. Qhov hnyav yuav txawv raws li qhov kam rau ua los ntawm cov yeeb nkab loj.
Cov txheej txheem los xam qhov hnyav ntawm cov yeeb nkab steel yog;
W=[{OD-WT} x WT] x 10. 69
W=Nyhav ib tus taw kab
OD=Txoj Kab Uas hla
WT=Phab Ntsa Thickness
Yeeb Tshuaj Raug
Cov yeeb nkab steel tau koom ua ob pawg loj;
Welded Yeeb Nkab
Seamless Yeeb Nkab
Muaj plaub txoj kev tseem ceeb ntawm kev ua cov yeeb nkab hlau:
Cub Hluav Taws Xob Weld (FW). Kuj hu ua Nruam Weld
Weld fais kuj (ERW)
Submerged Arc Weld (SAW), kuj DSAW
Seamless (SMLS) txoj kev
Hluav Taws Xob Kuj Weld Yeeb (ERW)
ERW Yeeb Nkab yog tsim los ntawm qhov ntau thiab tsawg los ntawm 1 / 8 rau 24 hauv NPS. ERW welded yeeb nkab yog tsim los ntawm cov ntawv hlau tiaj tus. ERW yeeb nkab yog thawj txias tsim ua rau cov ntawv muaj cov thooj voos kheej kheej thiab tom qab ntawd ces txuas ntev. ob leeg txuas ntxiv welded thiab elctric tsis kam welded yeeb nkab yog tsim los ntawm kev hloov cov ntawv yob ntawm coiled steel intocylindrical cov ntawv thiab vuam raws cov leeg ntev. Daim duab hauv qab no qhia thawj kauj ruam ntawm kev ua ib daim hlab ua cov duab cylindrical thiab tom qab ntawd fusing nws ua ke hauv 2 nd.
Muaj ntau txoj hauv kev rau lub sijhawm siv hluav taws xob rau siv rau lub vuam kab hlau rhuav. Qhov no suav nrog tig tooj liab disc, tsau alloy Cu tiv tauj thiab induction coils. Cov hau kev no nce qhov kub ntawm cov ntug hlau rau 2600 deg F rau kev vuam zoo. Cov txheej txheem dov tawm ntau dhau ntawm lub zog uas nws tsim lub hlau khawm txuas rau ntawm qhov chaw sab nraud thiab sab nraud. Cov weld seams tau muab tshem tawm thaum lub sijhawm ua tiav. Lub welded yeeb nkab yog kev kho cua sov, kuaj xyuas thiab kuaj hydro.
ERW cov yeeb nkab muaj nyob rau hauv kev ua raws li cov qauv tshwj xeeb;
ASTM A 53, A 135, A 252, A 500, A 795, API 5 L thiab API 5 I.
Feem ntau cov qhov tshwj xeeb rau cov yeeb nkab welded yog A 53 thiab API 5 L.
Seamless Yeeb Nkab
Dab tsi yog seamless txhais tau? los yog tsis muaj ntsiab lus? peb tau txais cov lus nug no ntau. Seamless yeeb nkab yog tsim hauv qhov ntau thiab tsawg los ntawm 1 / 8 rau 36 " nominal. Seamless yeeb nkab tsis muaj qhov ntev ua tau seam lossis txuas thaum muab piv rau ERW yeeb nkab. Hauv cov ntsiab lus yooj yooj yim cov yeeb nkab tsis sib haum yog tsim los ntawm kev sib tsoo lub pob ncig lub ntsej muag kom ruaj khov tom qab hollow seamless yeeb nkab. Muaj ob txoj kev loj ntawm kev tsim cov yeeb nkab seamless;
Kub Lub Taub Hau Sib Tsoo
Extrusion Txheej Txheem Txoj Kev
Hauv kev rho tawm txheej txheem, cov ntawv foob kub ntawm cov hlau yog tsim rau hauv cov yeeb nkab sib khi los ntawm kev yuam cov billets dhau los ntawm extrusion tuag thiab dhau ntawm kev sib sau ua ke. Saib duab hauv qab no;
Kub txoj kev siv tho kev sib tsoo txoj kev yog cov txheej txheem ntau tshaj plaws ntawm kev tsim cov yeeb nkab seamless. Nyob rau hauv tus txheej txheem no cov billets kub tau yuam los ntawm kev sib hloov cov qob hnyav dhau lub mandrel lossis cov ntsaws ntsaws. Cov ntsaws ruaj khov ua rau lub qhov taub los ntawm kev siv lub tshuab kaw lus seamless. Daim duab hauv qab no qhia txog cov txheej txheem kub qeeb mentshis.
Seamless yeeb nkab hla ntau qhov tiav cov haujlwm xws li kev ntsuas ncaj ncaj, tshuaj xyuas, kuaj hydro thiab cov duab kos. Seamless yeeb nkab yog dav siv nyob rau hauv cov raj xa dej siab, kev tsim kho, roj av thiab chaw sam roj. Seamless yeeb nkab muaj nyob rau hauv cov ntawv hais hauv qab no;
ASTM A 53, A 106, A 252, A 333, A 335, A 501, A 523, A 589, API 5 L thiab API 5 CT. Feem ntau cov yeeb nkab tsis sib haum yog A 106 B.
Xaus tiav ntawm cov npoo tsawg dua cov kav dej muaj xws li cov npoo kawg ntawm txoj kab kev txiav plaub hau lossis txiav plaub fab. Seamless carbon steel yeeb nkab muaj nyob rau hauv dub, liab qab, galvanized lossis nrog epoxy txheej.
Hlau Yeeb ប្រវែង
Feem ntau cov kav hlau xa tawm hauv 21 ft ntev. Nws kuj tseem muaj nyob hauv Single Random Length (SRL) uas tuaj yeem nyob txhua qhov chaw ntawm 17 ft rau 24 ft. Ob Chav Random Ntev Ntev (DRL) yog hais txog cov kav dej uas tsawg kawg 37 ft ntev thiab mus txog 44 ft.
Hlau Yeeb Nkab Kawg
Muaj tsib hom ntau ntawm cov yeeb nkab hlau kawg tas;
Threaded thiab Coupled
Threaded tsis muaj Coupling
Tiaj Xaus - Txiav Xwmfab
Beveled rau Vuam - 30 deg bevel
Grooved Kawg - Txiav lossis dov rau kev sib txuas tshuab
Daim duab hauv qab no qhia tau hais tias txawv cov yeeb nkab steel kawg tas;

Kev sib koom ua ke rau qhov muaj zog ntxiv thiab ob npaug ntxiv rau cov yeeb nkab muaj zog yog taper threaded thiab recessed rau txhua qhov loj me. Daim duab saum toj no qhia qhov txuas ncaj tapped txuas thiab ncaj tapped txuas nrog ncig ua si.
Hlau Yeeb Nkab Yeeb Txheeb thiab Ntaus Cim
Cov yeeb nkab steel muaj nyob rau hauv kev sib txawv, qib, qhov hnyav, cov sij hawm thiab lwm yam. Li ntawd nws yog ib qho tseem ceeb kom paub cov cim steel yeeb. Cov yeeb nkab steel yog txheeb xyuas los ntawm cov xim pleev xim stencil lossis cov cim ntaus cim rau ntawm cov yeeb nkab nws tus kheej lossis los ntawm daim pib txuas rau nws.
Kev txheeb xyuas yeeb nkab raws li ASTM
Daim duab hauv qab no qhia cov cim ua raws li ASTM cov lus qhia tshwj xeeb
Cov cim xaib ib qho API
Daim duab hauv qab no qhia tias yuav tsum khij raws qhov API tshwj xeeb.
Hlau Yeeb Tiav Cov Txheej Txheem tiav
Feem ntau ua tiav ntawm cov yeeb nkab hlau yog lacquer txheej uas tiv thaiv xeb thiab tiv thaiv cov yeeb nkab los ntawm huab cua. Qhov no tseem hu ua Dub Yeeb Yeeb Nkab. Lwm yam tshaj li lacquer, muaj plaub hom hlau yeeb nkab tag;
Hlau Liab Hlau
Pickled nkaus xwb
Pickled thiab Oiled
Galvanized Yeeb Nkab
Galvanizing koom nrog siv zinc txheej ua cov khoom fij tseg los tiv thaiv xeb. Zinc feem ntau yog thov los ntawm cov txheej txheem dej kub qhov twg cov yeeb nkab yog xa mus rau hauv lub cev da dej ntawm zinc tov. Cov qauv hnyav ntawm zinc yog 1. 8 oz ib sq ft. Galvanized kav muab kev tiv thaiv zoo rau cov yeeb nkab hauv thiab tawm.
Hlau Yeeb Nkab Txheej thiab Lined Steel Yeeb Nkab
Cov yeeb nkab' s corrosion kuj tseem tuaj yeem txhim kho nrog corrosion resistant yeeb txheej. Cov tsho zoo li no feem ntau siv ntev ntev piv nrog lacquer lossis galvanized tiav. Muaj peb qho tseem ceeb ntawm Kev Txhuam Txhuam Hnav Tiv Thaiv rau Hlau Yeeb

Cov Yeeb Nkab Hlau Yeeb
Lub pas hlau tsis xeb yog hlau li cov xaim muaj qhov tsawg kawg ntawm 16% chromium. Nickel yog lwm qhov tseem ceeb rau alloying hauv cov yeeb nkab steel hlau. Cov yeeb nkab hlau Stainless muaj cov tshuaj tiv thaiv zoo tshaj tawm rau cov xov xwm tawm thiab kom oxidation thaum yuav luag txhua yam ntsuas kub.
Stainless hlau welded thiab cov kav dej tsis xeb tau siv rau ntau qhov laj thawj xws li tiv taus xeb, preform ntawm qhov kub, rau kev saib kom zoo thiab qis tus nqi. Lub ntsej muag tseem ceeb tshaj plaws rau cov yeeb nkab steel hlau yog nws cov khoom siv xam qhov kev tso cai uas tso cai rau ntau cov phab ntsa thinner tsim xws li sch 5, sch 10 tsis muaj qhov cuam tshuam rau kev ntseeg siab ntawm cov yeeb nkab. Kev siv ntawm fusion welding los koom nrog cov yeeb nkab kuj tseem tshem tawm qhov kev xav tau ntawm txoj xov.
Hom 304 cov yeeb nkab steel hlau feem ntau yog siv rau kev siv tshuaj tiv thaiv corrosive. nws yog siv hauv cov nroj tsuag chemical, chaw tsim tshuaj, ntawv mills thiab kev lag luam khoom noj khoom haus. 304 SS yeeb nkab muaj cov pa roj carbon ntau ntawm 0. Nws tsis pom zoo rau siv nyob rau hauv qhov kub thiab txias ntawm 800 deg F thiab 1650 deg F vim yog carbide nag lossis daus ntawm thaj tsam ntawm cov lis. Hom 304 L yog tib yam li 304 tsuas yog tias nws muaj 0. 035% cov ntsiab lus carbon ntau kawg.
Hom 316 SS yeeb nkab yog qhov cuam tshuam ntau dua rau pitting dua li lwm cov chromium nickel alloys vim qhov ntxiv ntawm 2-3% molybdenum. Nws yog qhov muaj txiaj ntsig hauv kev siv nrog cov kua qaub, brines, dej sulfur, dej hiav txwv thiab nrog ntsev ntsev hologen. }%.
Welded Stainless Hlau Yeeb Nkab yog tsim los rau qhov tshwj xeeb ASTM A 312 thiab A 358. A 312 yog qhov feem ntau muaj qhov tshwj xeeb rau cov yeeb nkab steel hlau. Welded stainless yeeb yog tsim los ntawm 1 / 8 " rau 24 " NPS.
