Dab tsi "Carbon Seamless Pipe" txhais tau tias
Carbon seamless yeeb nkab yog tsim los ntawm cov khoom carbon steel billet, uas yog rhuab thiab pierced los ntawm nws qhov chaw siv ib tug teb piercing zeb, ces dov thiab loj mus rau qhov kawg sab nraud txoj kab uas hla thiab phab ntsa thickness. Vim hais tias cov yeeb nkab yog tsim los ntawm ib daim hlau es tsis yog dov los ntawm sawb thiab welded kaw, tsis muaj longitudinal los yog kauv seam nyob qhov twg raws nws ntev - ib tug structural txawv los ntawmERW(electric resistance welded) los yogSSAW(kauv submerged arc welded) yeeb nkab, ob qho tib si ntawm kev vam khom rau lub welded seam.
Txoj kev tsim khoom no ib txwm txwv txoj kab uas hla piv rau cov yeeb nkab welded: seamless yeeb nkab feem ntau muaj txog li ntawm 24 ntiv tes (610 hli) OD ua ntej tho- zeb muaj peev xwm thiab tus nqi dhau los ua qhov txwv, thaum welded yeeb nkab ib txwm txuas mus rau ntau qhov loj dua.
Common Standards thiab Qib
Carbon seamless yeeb nkab feem ntau raug txiav txim raws li ib qho ntawm cov qauv no, txhua lub hom phiaj rau ib daim ntawv thov kev pab sib txawv:
| Txuj | Hom Qib | Kev siv thawj zaug |
|---|---|---|
| ASTM A106 1 | Qib B, Qib C | High -kub kav dej (tswj fais fab, refineries) |
| ASTM A53 | Qib B (Type S, seamless) | Kev siv dav dav -lub hom phiaj kav, siv cov qauv thiab siv tshuab |
| API 5L | Qib B, X42–X70 | Roj thiab roj xa mus kav |
ASTM A106 1yog tus qauv feem ntau engineers ncav cuag los ntawm lub neej ntawd thaum cov yeeb nkab yuav pom qhov kub siab - nws suav nrog cov kev cai tshwj xeeb rau siab -kub txhua yam khoom uas A53 tsis nqa.ASTM A53npog qhov dav, dav dua - lub hom phiaj seamless (thiab welded) cov yeeb nkab siv thoob plaws txhua yam, cov qauv, thiab qis dua - cov kav dej hnyav. Paub meej tias tus qauv twg koj qhov project tiag tiag qhia - es tsis yog kho "cov pa roj carbon seamless yeeb nkab" raws li ib qho khoom sib hloov tau - yog ib qho ntawm cov khoom yuam kev uas cov neeg yuav khoom ua.
Mechanical Properties
Rau qib feem ntau xaj, ASTM A106 Qib B:
- Yield zog (min):240 MPa (35,000 psi)
- Tensile zog (min):415 MPa (60,000 psi)
- Elongation:Yam tsawg kawg nkaus yuav tsum tau sib txawv ntawm phab ntsa thickness, raws li tus qauv lub rooj
- Cov ntsiab lus carbon ntau tshaj: 0.30%
- Qhov siab tshaj plaws kev pabcuam kub:tswj hwm los ntawm ASME B31.1 / B31.3 piping code tso cai rau kev ntxhov siab, tsis yog cov khoom siv ib leeg
A106 Qib C yog siab dua qhov qis tshaj tawm thiab cov kev xav tau tensile (275 MPa / 485 MPa) rau cov ntawv thov xav tau lub zog ntau dua ntawm cov phab ntsa tuab, ntawm qee tus nqi rau weldability.
Qhov twg Carbon Seamless Yeeb Nkab yog qhov kev xaiv zoo
Seamless yeeb nkab feem ntau tau teev tseg thaum:
- Cov kav dej ua haujlwm ntawm qhov kub siab lossis siab qhov chaw weld-seam kev ncaj ncees yog qhov tsim thiab kev txhawj xeeb
- Daim ntawv thov poob rau hauv cov kav dej (ASME B31.1, B31.3) uas siv cov kev sib koom ua haujlwm zoo rau kev nplua welded yeeb nkab txheeb ze rau seamless
- Cov kev pabcuam tseem ceeb lossis muaj kev phom sij (steam, hydrocarbon txheej txheem kab) ua rau weld-seam soj ntsuam keeb kwm ib qho kev xaiv cov khoom
- Cov me me - txog - nruab nrab diameters koom nrog, qhov twg seamless ntau lawm ob qho tib si muaj thiab raug nqi - sib tw
Rau txoj kab uas hla loj dua, qis dua - siab, lossis cov kav dej siv dav dav, welded yeeb nkab (ERW lossis SSAW, nyob ntawm qhov loj) feem ntau yog qhov kev xaiv pheej yig dua, thiab cov kav dej niaj hnub welded nrog tag nrho -ntev NDT tshuaj xyuas ua tau zoo nyob rau hauv ntau yam kev pabcuam. Cov neeg yuav khoom yuav tsum paub meej tias lawv cov piping code thiab qhov project specification tiag tiag xav tau seamless ua ntej xav tias nws tsim nyog los ntawm lub neej ntawd.
Cov lus nug nquag nug (FAQ)
Q: Qhov txawv ntawm ASTM A106 thiab ASTM A53 seamless yeeb nkab yog dab tsi?
A: A106 yog sau tshwj xeeb rau kev ua haujlwm siab - kub thiab muaj xws li cov cuab yeej cuab tam uas yuav tsum tau khi rau siab - kev ua haujlwm kub; A53 npog dav dav - lub hom phiaj seamless thiab welded yeeb nkab yam tsis muaj qhov siab - qhov kub thiab txias. A106 feem ntau yog qhov kev xaiv raug rau cov txheej txheem thiab cov kav dej fais fab; A53 muaj nyob rau hauv kev siv tshuab dav dav thiab qis dua - kev siv hnyav.
Q: Puas yog carbon seamless yeeb nkab muaj zog dua welded yeeb nkab ntawm tib qib?
A: Tsis tas yuav tsum muaj lub zog ntawm cov khoom siv hauv paus - qhov ua tau zoo ntawm cov yeeb nkab seamless yog qhov tsis muaj vuam seam raws li qhov chaw muaj peev xwm, uas tseem ceeb tshaj plaws nyob rau hauv siab - siab, siab - kub, los yog qaug zog - kev pab cuam rhiab es tsis yog nyob rau hauv raw tensile zog.
Q: Qhov luaj li cas feem ntau muaj nyob rau hauv cov pa roj carbon seamless yeeb nkab?
A: Feem ntau seamless ntau lawm npog roughly 1/8 "mus txog 24" NPS, txawm tias muaj tseeb nyob ntawm lub zeb tho qhov muaj peev xwm - paub meej tias qhov loj me thiab lub sijhawm muaj nyob ncaj qha nrog koj tus neeg muag khoom rau txhua yam ntawm qhov kawg ntawm qhov ntau.
Q: Cov pa roj carbon seamless yeeb nkab puas tuaj yeem siv rau kev pabcuam qaub lossis corrosive?
A: Txheem ASTM A106 / A53 cov khoom siv tsis tuaj yeem tsim nyog rau kev pabcuam qaub - qaub lossis NACE MR0175-raws li daim ntawv thov xav tau cov khoom tsim nyog ntxiv thiab yuav tsum tau teev tseg nyias hauv daim ntawv xaj khoom.
