Loj - txoj kab uas hla ncaj - seam welded steel kav feem ntau xa mus rau cov kav dej nrog txoj kab uas hla ntau dua 325 mm. Rau tuab-walled loj- txoj kab uas hla ncaj- seam welded kav, ob -sided submerged arc vuam (SAW) yog cov txheej txheem tseem ceeb, kom ntseeg tau qhov tob tob, vuam zoo, thiab zoo heev weld tsim. Hauv qee qhov xwm txheej, kev tuav vuam yuav raug siv los ua cov txheej txheem ntxiv tom qab tsim cov yeeb nkab.
Q235B LSAW welded steel kav yog dav siv nyob rau hauv ntev - cov kav dej nyob deb, kev tsim kho vaj tse, kev tsim kho hauv nroog, cov khoom siv dej, cov hauv paus hauv paus, cov phiaj xwm choj, thiab kev lag luam tawm sab nrauv vim lawv txoj kev ntseeg siab thiab kev ua haujlwm zoo heev.
Lub ntsiab nta ntawm Q235B LSAW Welded Steel Pipe
1. Tsis tshua muaj kev ntxhov siab sab hauv tom qab siv tshuab nthuav dav
Tom qab tag nrho cov neeg kho tshuab nthuav dav, qhov kev ntxhov siab sab hauv hauv cov yeeb nkab steel yog txo qis thiab sib npaug.
Qhov no tiv thaiv kev ntxhov siab -corrosion cracking, txhim kho lub sij hawm ntev - kev ntseeg tau.
2. Zoo heev Dimensional raug
Cov txheej txheem tsim thiab vuam ua kom muaj kev sib tw siab, ncaj, thiab qhov ntev, ua rau ntawm - qhov chaw vuam thiab kev teeb tsa tau zoo dua.
3. Cov txheej txheem vuam ruaj khov & Siab Weld zoo
Siv ua ntej- vuam + precision- lub zog vuam, LSAW kav muaj:
ruaj khov arc
High -zoo, zoo welds
Zoo sab hauv / sab nraud weld zoo
Lub vuam seam yog ncaj, luv, thiab yooj yim rau tsis yog -kev kuaj kev puas tsuaj (NDT) xws li X-ray, UT, lossis RT.
4. Kev pheej hmoo tsawg dua ntawm vuam tsis zoo
Piv nrog rau cov kav dej welded los yog tsis yog - ncaj- seam kav, qhov ncaj seam ho txo tag nrho cov weld ntev, uas txo qhov tshwm sim ntawm weld defects.
5. Ntau yam ntawm Specifications
LSAW technology txhawb kev tsim khoom ntawm:
Me - txoj kab uas hla tuab - cov kav dej
Loj - txoj kab uas hla tuab - cov kav dej
Kev cai ntev thiab phab ntsa thicknesses
Qhov no ua rau cov khoom lag luam hloov tau zoo nyob hauv ntau qhov chaw engineering.
JCOE vs. UOE Cov txheej txheem tsim
| Yam ntxwv | JCOE Process | Txheej txheem UOE |
|---|---|---|
| Kev tsim cov yam ntxwv | Cov kauj ruam nce qib-los ntawm- kauj ruam tsim, hloov tau yooj yim heev | Ib -theem siab- lub zog tsim |
| Kev Ua Tau Zoo | High -kev tsim khoom zoo nrog kev ruaj ntseg zoo | Tsis tshua muaj kev ua haujlwm siab thiab tsim precision |
| Cov khoom sib xws | Kev ua tau zoo thiab txhim khu kev qha zoo | Zoo sib xws; superior roundness rau ultra- loj diameters |
| Daim ntawv thov | Dav siv nyob rau hauv ntau yam diameters, haum rau ntau hom khoom siv; cov txheej txheem tseem ceeb hauv Suav teb | Zoo tagnrho rau huab hwm coj ntau lawm ntawm ultra- txoj kab uas hla loj; ntev - tau tsim cov txheej txheem tseem ceeb thoob ntiaj teb |
Qhov zoo ntawm ib Glance
Ob npaug -sided SAW rau superior weld nkag
Zoo heev dimension tswj
Tsawg residual stress tom qab expansion
Yooj yim dua ntawm - qhov chaw teeb tsa thiab tshuaj xyuas
Ua tiav nrog txhua txoj hauv kev loj NDT
Haum rau loj - nplai infrastructure thiab ntev - cov kav dej nyob deb
