Cov pa roj carbon steel 45℃lateral tee yog lub pob tw weld yeeb nkab haum siv los txuas cov ceg kab mus rau lub kav dej loj ntawm 45-degree kaum sab xis. Piv nrog rau cov pa 90-degree tee, cov ceg kaum sab xis muab kev hloov pauv hloov pauv hauv cov kev taw qhia ntws, txo cov dej ntws tawm thiab kev poob siab hauv cov kav dej siab tshaj plaws.
Qhov kev haum no tau hais dav dav hauv cov txheej txheem kav dej thoob plaws cov roj thiab roj, petrochemical, tsim hluav taws xob, thiab cov chaw ua tshuaj.
Qhov project yuav khoom rau ib sab tee muaj ntau tshaj qhov sib piv cov yeeb nkab nominal. Main thiab ceg diameters, phab ntsa thickness teem, cov khoom qib, bevel configurations, thiab dimensional tolerances yuav tsum nruj me ntsis raws li cov qauv engineering ua ntej pib tsim.

Cov qib khoom thiab cov txheej txheem xaiv
Cov pa roj carbon steel lateral tees yog tsim los kom phim cov khoom siv kho tshuab thiab tshuaj lom neeg ntawm cov yeeb nkab txuas txuas. Standard cov khoom specifications muaj xws li:
ASTM A234 WPB / WPC Khoom:Txheem carbon steel wrought fittings rau nruab nrab thiab siab -kev pabcuam kub.
ASTM A420 WPL6 Cov Lus Qhia:Tsawg-kub carbon steel fittings yuav tsum tau kuaj qhov cuam tshuam (Charpy V-Notch) ntawm sub-zero ib puag ncig.
ASTM A 860 WPHY Series:High- tawm los carbon steel fittings tsim rau siab - cov kav xa dej siab.
Kev xaiv nyob ntawm qhov tsim kub, kev khiav hauj lwm siab, kua nruab nrab, thiab vuam yuav tsum. Cov neeg yuav khoom yuav tsum qhia seb puas yog tom qab -weld heat treatment (PWHT) lossis cov pa roj carbon sib npaug (CE) txwv yuav tsum tau ua los ntawm txoj haujlwm code.
Txoj Kev Tsim Khoom & Kev Tsim Kho
Cov txheej txheem tsim khoom yog txiav txim los ntawm qhov loj me, geometry, phab ntsa thickness, thiab qhov project specifications:
Seamless Kev Tsim Kho
Ua los ntawm seamless yeeb nkab los yog forged billets, feem ntau xaiv rau qhov me me los yog siab - cov chav kawm siab uas yuav tsum muaj cov qauv nplej tas li.
Welded Tsim
Siv rau cov qauv loj dua uas tau tso cai los ntawm cov khoom siv thiab cov kav dej tshwj xeeb, suav nrog tag nrho -kev nkag welds raug rau nruj tsis- kuaj kev puas tsuaj (NDT).
Fabricated Tsim
Siv rau qhov tsis yog - qhov loj me, hnyav phab ntsa thicknesses, los yog complex txo cov geometry ua raws li kev pom zoo engineering kos duab
Kev kho deg & Kev tiv thaiv corrosion
Txhawm rau tiv thaiv atmospheric corrosion thaum dej hiav txwv freight thiab cia, carbon steel fittings undergo nruj deg npaj ua ntej xa:
Nto ntxuav
Txhaj tshuaj blasting los yog sandblasting kom tshem tawm zeb nplai, oxides, thiab deg impurities, ua tiav qhov kev pom zoo.
Kev tiv thaiv txheej
Coated nrog anti- xeb roj, pob tshab kua roj vanish, los yog xim dub raws li qhov yuav tsum tau ua.
Kev Tiv Thaiv Bevel
Cov kaus mom yas ntsia tau rau ntawm ob qho tib si khiav thiab ceg xaus los tiv thaiv cov vuam bevels los ntawm kev puas tsuaj thaum lub sij hawm thauj mus los.
Dimensional Control & Critical Inspection Points
Vim hais tias lateral tees feature ib qho mob siab - lub kaum sab xis kev sib tshuam, qhov tseeb qhov tseeb ncaj qha cuam tshuam rau kev cob qhia prefabrication thiab teb haum-up. Cov ntsiab lus tseem ceeb ntawm kev tswj hwm muaj xws li:
Ceg Angle Tolerance
Xyuas kom lub kaum sab xis 45-degree conforms nruj me ntsis rau kev tsim cov duab kos los tiv thaiv angular misalignment thaum vuam.
Center-rau-End Dimensions
Kev ntsuas meej los ntawm qhov chaw khiav mus rau ceg thiab khiav xaus.
Phab ntsa Thickness thiab ovality
Kev txheeb xyuas ntawm ob qho tib si lub ntsiab khiav thiab ceg qhov hluav taws xob, tshwj xeeb tshaj yog nyob ib puag ncig thaj tsam crotch qhov twg muaj kev ntxhov siab ntau tshaj.
Bevel Geometry
Hauv paus lub ntsej muag, bevel kaum sab xis (feem ntau yog 37.5 degree), thiab sab hauv txoj kab uas hla sib txuam kom ntseeg tau tias lub suab vuam ua tiav.
Kev Tswjhwm Zoo thiab cov ntaub ntawv pob
Txhawm rau ua kom tau raws li qhov yuav tsum tau ua kom muaj kev ruaj ntseg zoo, kev tsim khoom yog txhawb nqa los ntawm cov ntaub ntawv pov thawj thiab cov txheej txheem pov thawj:
Material Test Certificate (MTC)
Muab khoom raws li EN 10204 3.1, piav qhia txog tshuaj lom neeg muaj pes tsawg leeg thiab cov txiaj ntsig kev ntsuas tshuab.
Dimensional Inspection Reports
Txheeb xyuas qhov ntsuas qhov tseeb tiv thaiv kev kos duab.
Tsis yog -Kev Tshawb Fawb Kev Puas Tsuaj (NDE)
Kev kuaj hluav taws xob (RT), kuaj ultrasonic (UT), kuaj cov hlau nplaum sib nqus (MT), lossis tshuaj ntsuam xyuas xim (PT) thaum teev los ntawm kev yuav khoom.
Cov ntaub ntawv kho cua sov
Kev kaw cov austenitizing, quenching, thiab tempering los yog kev ntxhov siab -relieving cycles qhov muaj feem xyuam.
FAQ
Q: Qhov txawv ntawm 45℃lateral tee thiab 90℃standard tee yog dab tsi?
A: Tus qauv 90-degree tee coj cov ceg ntws perpendicularly mus rau lub ntsiab khiav, whereas 45-degree lateral tee ces kaum ceg ntawm 45 degrees. Qhov kev hloov pauv hloov maj mam no ua rau txo qis cov dej ntws tawm, kev poob siab, thiab kev yaig ntawm cov khoom siv hluav taws xob hauv high-velocity lossis abrasive fluid systems.
Q: Koj puas tuaj yeem muab txo cov tees sab nraud uas cov ceg loj me dua qhov kev khiav haujlwm tseem ceeb?
A: Yog. Lateral tees tuaj yeem tsim tau raws li qhov sib npaug sib npaug lossis txo cov teeb tsa. Cov pab pawg yuav khoom yuav tsum qhia ob qho tib si qhov loj ntawm qhov loj me thiab cov ceg qhov hluav taws xob qhov ntev thaum thov kev tsocai.
Q: Koj tuaj yeem txheeb xyuas qhov tseeb ntawm 45-degree ceg kaum lub sijhawm ua haujlwm li cas?
A: Kev kuaj xyuas tshwj xeeb, kev sib koom tes ntsuas cov cuab yeej, thiab cov ntsuas lub kaum ntse ntse yog siv thaum tsim khoom. Rau cov kev cai- engineering tej yaam num, qhov ntev thiab lub kaum sab xis yog cross- hais ncaj qha rau kev pom zoo isometric layout kos duab ua ntej kawg vuam los yog tsim.
Q: Cov ntaub ntawv dab tsi yog muab nrog cov khoom xa tuaj?
A: Cov ntaub ntawv txheej txheem suav nrog Cov Ntawv Pov Thawj Kev Xeem (MTC) ua raws li EN 10204 3.1, cov ntaub ntawv tshuaj xyuas qhov ntev, thiab cov ntaub ntawv kho qhov chaw / cua sov. Thib peb-kev tshuaj ntsuam xyuas tog (TPI) cov ntawv ceeb toom los ntawm cov koom haum xws li SGS, BV, lossis DNV kuj tuaj yeem teem caij rau ib daim ntawv cog lus yuav khoom.
Q: Puas yog vuam xaus machined raws li cov qauv thoob ntiaj teb?
A: Yog. Butt weld xaus yog tus qauv bevelled ua raws li ASME B16.25, kom ntseeg tau qhov sib txawv hauv paus thiab nkag mus thaum lub sijhawm ua haujlwm lossis kev cob qhia vuam.
