Peb tsim thiab xa tawm kauv welded siab siab dej yeeb nkab rau cov dej xa hluav taws xob, lub twj tso kua mis tso tawm kab, cov kab dej hauv lub cev, thiab cov twj siv hluav taws xob. Hauv qab no peb piav qhia qhov ua tau ua rau cov kav hlau txuas txuas "siab siab" ntsuas, peb tswj nws li cas, thiab qhov twg cov neeg yuav khoom feem ntau khiav mus rau qhov teeb meem xaj cov khoom no los ntawm lub tshuab tsis paub.
Dab tsi "High Pressure" txhais tau tias rau kauv welded yeeb nkab
Ntau tus neeg yuav khoom xav tias qhov ntsuas siab tsuas yog ua haujlwm ntawm phab ntsa tuab xwb. Qhov ntawd tsuas yog ib nrab ntawm kev suav. Lub siab lub yeeb nkab tuaj yeem nqa tau zoo li nram qab noBarlow's Formula:P = (2 x S x t x E) / D
Qhov twg S yog cov khoom siv zog, t yog phab ntsa tuab, D yog sab nraud, thiabE yog qhov sib koom ua ke ua haujlwm zoo. Rau SSAW yeeb nkab, E tsuas yog 1.0 thaum lub kauv seam tau lawm100% ultrasonically kuajthiab cov yeeb nkab tau dhau lawmzeb hydrostatic xeem kom tsawg kawg yog 90% ntawm qhov tsawg kawg nkaus yield zog (SMYS). Cov yeeb nkab uas muaj tib txoj kab uas hla thiab phab ntsa tuab tab sis kev sib koom ua haujlwm qis dua (ib nrab NDT, tsis muaj cov ntaub ntawv kuaj dej) yogtsis ntsuas rau tib lub siab, txawm tias nws zoo ib yam ntawm daim ntawv dimension.
Qhov no yog qhov sib txawv loj tshaj plaws uas peb pom ntawm qhov tus neeg yuav khoom xav tias lawv tab tom xaj thiab tus nqi qis npaum li cas - tus nqi xa khoom tiag tiag: yog OD thiab phab ntsa tuab, tab sistsis muaj ntaub ntawv sib koom ua haujlwm los txhawb lub xeev cov chav kawm siab.
Cov qauv peb tsim tawm tsam
- API 5L- kab yeeb nkab qauv, siv qhov project qhia cov roj-thiab- roj- cov ntaub ntawv qib txawm rau daim ntawv thov dej
Peb sib phim tus qauv, qib, thiab kev xeem tswj hwm rau koj qhov project spec es tsis yog defaulting rau qhov twg daim ntawv pov thawj pheej yig tshaj los tsim - qhov ntsuas siab tsuas yog tuav yog tias daim ntawv pov thawj tiag tiag phim cov khoom xa tuaj.
Yuav Ua Li Cas Peb Tswj Kev Ruaj Ntseg Thaum Ua Haujlwm
- Coil xaiv- steel coil chemistry thiab cov khoom siv kho tshuab raug txheeb xyuas tawm tsam cov hom phiaj (xws li X42-X70 rau API 5L) ua ntej pib pib.
- Kauv forming (JCOE- sib npaug)- coil yog pub los ntawm kauv ua yob ntawm lub kaum sab xis tswj helix, nrog rau qhov sib txawv seam tuav kom kam rau siab ua ntej vuam.
- Ob chav -sab submerged arc vuam (DSAW)- cov seam yog welded los ntawm sab hauv thiab sab nraud nyob rau hauv nyias passes, muab tag nrho nkag mus rau hauv lub thickness ntawm phab ntsa.
- 100% ultrasonic kuaj ntawm vuam seam- txhua lub 'meter' ntawm kauv thiab girth weld yog scanned, tsis pom - qauv, los txhawb kev sib koom ua haujlwm ntawm 1.0.
- Mill hydrostatic xeem- txhua lub yeeb nkab raug ntsuas siab mus rau qib uas tau teev tseg los ntawm kev tswj hwm tus qauv (feem ntau 90%+ SMYS), tuav rau lub sijhawm nyob hauv tsev, nrog lub siab thiab lub sijhawm nkag rau ib lub yeeb nkab.
- Dimensional thiab roundness soj ntsuam- OD, phab ntsa thickness, thiab tawm - ntawm - roundness raug kuaj xyuas ua ntej txheej thiab txheej.
- Daim ntawv thov txheej sab hauv thiab sab nrauv txheej- cement mortar hauv ob sab phlu lossis epoxy rau sab hauv; 3PE, FBE, lossis thee tar epoxy rau sab nraud, nyob ntawm cov av / dej chemistry.
Kev ntsuas siab, lub sijhawm nyob hauv, thiab UT kev pab them nqi raug kaw rau ib tus lej kav thiab suav nrog hauv daim ntawv pov thawj zeb xeem - tsis suav nrog qhov nruab nrab batch.
Txoj kab uas hla, Phab ntsa Thickness, thiab Kev Taw Qhia ntawm Chav Kawm Siab
Lub peev xwm siab tsis yog phab ntsa nkaus xwb -thickness lookup - nws nyob ntawm qib, txoj kab uas hla, thiab tsim qauv ua ke. Raws li tus qauv dav dav:
- Cov kab me me (DN300-DN600):Cov chav kawm siab dua yog yooj yim dua mus cuag nrog cov phab ntsa tuab tuab, feem ntau hauv cov twj tso kua mis tawm thiab cov kab booster.
- Nruab nrab txoj kab uas hla (DN600-DN1500):phab ntsa thickness ua tus thawj lever; Kev xaiv qib (API 5L X52-X65) pib muaj teeb meem ntau dua li qhov me me.
- Loj txoj kab uas hla (DN1500+):tsim siab feem ntau yog nruab nrab- mus rau- siab tab sis tsis hnyav, txij li cov xaim hluav taws xob ntawm qhov loj me no feem ntau yog lub ntiajteb txawj nqus- pub lossis qis - nrawm nrawm; phab ntsa thickness yog tsav ntau npaum li cas los ntawm tuav / buckling kuj thaum lub sij hawm installation raws li nyob rau hauv lub siab ib leeg.
Peb suav cov phab ntsa tuab tiv thaiv koj qhov kev tsim tsim siab, kev tso nyiaj nce siab, thiab kev nyab xeeb ntau dua li kev xa khoom "tus qauv" phab ntsa rau txoj kab uas hla - xa tuaj rau peb koj qhov kev tsim siab thiab txoj kab uas hla thiab peb yuav xa cov phab ntsa tuab thiab qib kev pom zoo nrog rau kev suav qhia.
Ib Case Tsim Nyog Paub
Ib tus neeg cog lus muab 1200mm SSAW yeeb nkab rau lub hauv paus kis tau tus mob loj xaiv tus neeg muag khoom raws li phab ntsa tuab thiab OD ib leeg, piv txwv tias nws phim lawv tus engineer tsim siab ntawm 1.6 MPa. Thaum cov ntawv pov thawj zeb kuaj tau tuaj txog, cov ntaub ntawv kuaj dej hydrostatic pom cov kav dej tsuas yog tau sim rau kwv yees li 80% SMYS, tsis yog 90% + qhov kev qhia tshwj xeeb yuav tsum tau los txhawb qhov kev sib koom ua ke ntawm cov kev xav tau siv nyob rau hauv thawj phab ntsa -thickness xam. Cov yeeb nkab yog dimensionally tseeb tab sistsis tuaj yeem lees paub rau qhov tsim siab ntawm daim ntawv, yuam kom ncua thaum lub batch tau rov- sim thiab rov- ntaub ntawv. Zaj lus qhia rau cov neeg yuav khoom:tshawb xyuas qhov ntsuas hydrostatic siab thiab nyob hauv lub sijhawm ntawm daim ntawv pov thawj zeb tawm tsam koj qhov kev tsim siab suav ua ntej cov yeeb nkab tawm hauv lub zeb, tsis yog tom qab nws tuaj txog ntawm qhov chaw.
Vim li cas cov neeg yuav khoom ua haujlwm nrog peb rau cov kav dej siab siab

FAQ
Q: Dab tsi yog qhov siab tshaj plaws ntsuas koj tuaj yeem tsim rau kauv welded yeeb nkab?
A: Nws nyob ntawm txoj kab uas hla, phab ntsa thickness, thiab qib ua ke, tsis yog ib tus lej tas. Xa peb koj txoj kab uas hla, tsim siab, thiab tus qauv nyiam thiab peb yuav rov qab cov phab ntsa tuab thiab qib kev pom zoo nrog kev txhawb nqa.
Q: Puas yog kauv welded (SSAW) yeeb nkab haum rau kev pabcuam siab, lossis peb puas yuav tsum siv cov yeeb nkab ncaj nraim hloov?
A: SSAW yeeb nkab tuaj yeem raug ntsuas rau kev pabcuam siab thaum cov hlua khi yog 100% UT kuaj thiab kuaj hydrostatically rau qib koj tus qauv xav tau, muab kev sib koom ua haujlwm ntawm 1.0. Lub seam orientation tsis nws tus kheej txwv qhov ntsuas siab - qhov kev sim thiab cov ntaub ntawv tom qab nws ua.
Q: Koj puas muab cov cement mortar hauv ob sab phlu, lossis nws puas ntxiv cais tom qab peb tau txais cov yeeb nkab?
A: Peb siv cov cement mortar hauv ob sab phlu (AWWA C205) lossis epoxy hauv ob sab phlu hauv -lub tsev ua ntej cov yeeb nkab ships, yog li nws tuaj txog npaj rau kev teeb tsa es tsis xav tau tus neeg ua haujlwm hauv ob sab hauv.
Q: Cov ntaub ntawv dab tsi tuaj nrog cov yeeb nkab?
A: Daim ntawv pov thawj zeb xeem (3.1 lossis 3.2 rau EN 10204 ntawm kev thov) qhia cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, ntsuas dej hydrostatic thiab lub sijhawm nyob hauv ib lub yeeb nkab, thiab UT cov ntaub ntawv pov thawj, taug qab los ntawm cov xov tooj cua sov thiab cov yeeb nkab.
