Dab tsi yog Steel Pipe Tee Ua
Cov yeeb nkab tee yog ib ceg haum uas sib faib lossis sib txuas ntawm cov kav dej los ntawm kev tsim lub qhov hluav taws xob 90℃los ntawm cov yeeb nkab khiav. Nyob rau hauv lub pob tw weld tsim lub tee yog qhov muaj zog tshaj qhov ua tau zoo los ua ib ceg: qhov haum yog welded rau hauv txoj kab, nws cov bore sib tw khiav thiab ceg kav dej, thiab qhov chaw crotch reinforced nqa lub siab thiab khoov loads uas ib tug welded stub - ntawm ceg tsis tuaj yeem. Tees yog muab los ua seamless los yog welded fittings, thiab lawv yog dimensioned kom lub chaw - mus rau -kawg thiab centre - mus rau - ceg ntev kab nrog rau mating yeeb nkab.
Hom Steel Pipe Tee
Tees tau muab faib ua peb txoj hauv kev: los ntawm ceg txoj kab uas hla, los ntawm kev sib txuas hom thiab los ntawm cov khoom siv. Geometry variants xws li tus ntoo khaub lig tee, luv tee thiab forged tee kuj tau teev tseg rau cov layouts.
Los ntawm ceg diameter:sib npaug tee, qhov twg khiav thiab ceg yog tib yam loj, thiab txo tee, qhov twg ceg yog me dua qhov khiav.
Los ntawm kev sib txuas:taub qab weld tee, qhov (socket) weld tee thiab threaded tee. Butt weld tees pab kev kub siab thiab loj bore kab; socket weld thiab threaded tees haum me me bore utility thiab ntsuas piping.
Los ntawm cov khoom siv:carbon steel tee, alloy steel tee thiab stainless hlau tee.
Los ntawm geometry:cross tee nrog ob qhov hluav taws xob, luv tee, thiab forged tee tsim los ntawm forging es tsis yog los ntawm vuam ib ceg mus rau qhov ntev ntawm cov yeeb nkab.
Cov ntaub ntawv thiab cov qauv siv tau
Qib ntawm ib lub tee yog txhais los ntawm qhov haum specification, tsis yog los ntawm cov yeeb nkab nws yog welded rau, thiab ob yuav tsum tau sib phim thaum xaiv.
| Cov khoom siv | Common qib thiab specifications |
|---|---|
| Cov pa roj carbon steel | ASTM A234 WPB, WPC; ASTM A105, A106, A53; API 5L Gr B; ASTM A671 CC-70; ASTM A515 Qib 50; ASTM A135 Qib A; ASTM A179 Qib C |

| Hlau alloy | ASTM A234 WP1, WP5, WP9, WP11, WP12, WP22, WP91 |
| Qhov ntev | ASME B16.9 (thawj luam tawm raws li ANSI B16.9) |
Wrought carbon thiab alloy fittings yog them los ntawm ASTM A234 / A234M, uas teev cov qib thiab lawv cov khoom siv kho tshuab; stainless hlau fittings yog them los ntawm ASTM A403 / A403M, qhov twg txhua qib nqa WP prefix. Dimensional tswj rau lub Hoobkas- ua wrought fittings los ntawm ASME B16.9, thiab cov piping codes uas siv nws tswj kev teeb tsa, kuaj thiab kuaj. Thaum cov yeeb nkab khiav yog API 5L kab yeeb nkab, qhov sib txuam haum qib feem ntau yog A234 WPB, nrog rau qhov kub tsis tshua muaj kev cuam tshuam - qib ntsuas hloov rau kev pabcuam txias.
Mechanical Properties ntawm Common Tee Qib
| Qib | Yam tsawg kawg yield zog | Tensile zog ntau yam |
|---|---|---|
| ASTM A234 WPB 1 | 240 MPa | 415-585 MPa |
| ASTM A234 WPC Txheem | 275 MPa rau | 485-655 MPa |
| ASTM A234 WP11 | 310 MPa | 515-690 MPa |
| ASTM A234 WP22 | 310 MPa | 515-690 MPa |
| ASTM A234 WP91 | 415 MPa rau | 585-760 MPa |
Cov qib alloy xws li WP11, WP22 thiab WP91 raug xaiv rau kev pabcuam kub siab, qhov twg nkag tau lub zog thiab oxidation kuj tseem ceeb tshaj qhov kub ntawm chav tsev. Cov qib no ib txwm muab nkag rau hauv qhov normalized thiab tempered lossis normalized mob, thiab lawv cov kev kho cua sov raug txheeb xyuas ntawm daim ntawv pov thawj zeb.
Loj, Phab ntsa Thickness thiab nto tiav
Tees raug txiav txim los ntawm nominal yeeb nkab loj thiab phab ntsa thickness teem caij, nrog rau cov ceg loj tau teev tseg rau kev txo cov khoom.
Qhov ntau thiab tsawg:NPS 1/2 in. to 36 in., sib npaug rau DN 15 txog DN 900
Phab ntsa thickness:2 hli txog 80 hli, nrog SCH 40, SCH 80 thiab XXS muaj raws li tus qauv siv
Nto tiav:lub teeb oiling los yog dub painting rau carbon thiab alloy steel, pickling los yog passivation rau stainless hlau
Ntim:ntoo rooj plaub los yog ntoo pallets, nrog lub kaus mom tiv thaiv kom cov weld bevels huv si hauv kev thauj mus los

FAQ: steel yeeb nkab Tees
Q: Dab tsi yog qhov txawv ntawm qhov sib npaug tee thiab txo tee?
Ib qho sib npaug tee muaj ib ceg ntawm tib lub npe loj li kev khiav, thaum lub tee txo qis muaj ceg ib lossis ntau qhov me me dua qhov kev khiav.
Q: Cov qauv twg npog carbon steel yeeb nkab tees?
ASTM A234 / A234M txhais cov qib thiab cov khoom siv kho tshuab, thiab ASME B16.9, Ameslikas luam tawm raws li ANSI B16.9, teeb tsa qhov ntev thiab qhov kam rau ua.
Q: Thaum twg yuav tsum siv lub qhov (socket) weld tee es tsis txhob siv lub pob tw weld?
Lub qhov (socket) weld tees haum cov kab me me uas qhov kev sib tw thiab haum- yuav nyuaj; taub qab weld tees yog siv rau kev kub siab, kub kub thiab kev pab cuam loj.
Q: Dab tsi loj thiab phab ntsa thickness ntau yog muaj?
Tees yog muab los ntawm NPS 1/2 in. to 36 in. (DN 15 to DN 900) nrog phab ntsa thickness ntawm 2 hli mus rau 80 hli, suav nrog SCH 40, SCH 80 thiab XXS cov ntaub ntawv.
Q: Cov tee qib twg yog siv rau kev pabcuam kub kub?
Alloy qib xws li ASTM A234 WP11, WP22 thiab WP91 raug xaiv rau cov kav dej kub siab vim lawv khaws lub zog thiab tiv thaiv oxidation ntawm qhov kub thiab txias.
Q: Qhov kev kho deg thiab ntim khoom yog dab tsi?
Cov pa roj carbon thiab alloy tees yog muab nrog lub teeb oiling lossis pleev xim dub thiab ntim rau hauv cov rooj ntoo lossis ntawm cov ntoo pallets, nrog rau kev tiv thaiv bevels.
