Cov yam ntxwv ntawm API 5L LSAW Steel Pipe
1. Superior Strength thiab Weld Quality
LSAW cov kav dej siv ob -sab submerged arc vuam txheej txheem, uas ua kom muaj kev sib sib zog nqus sib sib zog nqus thiab sib sib zog nqus vuam siab. Lub flux-cov arc npog minimizes impurities thiab oxidation, uas ua rau welds nrog zoo heev toughness, ductility, thiab ntom-piv rau lub hauv paus hlau nws tus kheej.
2. Txoj kab uas hla loj thiab tuab -Puas muaj peev xwm
Cov kav dej no yog tsim los rau loj - nplai infrastructure, nrog txoj kab uas hla ntawm 406.4 hli mus rau tshaj 1422 hli thiab phab ntsa thickness txog li 50 hli. Qhov no ua rau lawv zoo tagnrho rau siab - cov roj thiab cov pa xa hluav taws xob, cov kav dej tawm sab nrauv, thiab cov txheej txheem piling hauv qhov xav tau ib puag ncig.
3. High Dimensional Accuracy thiab Low Residual Stress
Los ntawm kev nthuav dav ntawm kev siv tshuab (xws li UOE lossis JCOE cov txheej txheem tsim), LSAW cov kav dej tau ua tiav qhov sib npaug (ovality Tsawg dua lossis sib npaug ntawm 0.5% D) thiab ncaj (tsawg dua lossis sib npaug li 1.5 hli ib meter). Qhov no txo cov kev ntxhov siab ntawm qhov seem ntawm vuam thiab ua kom muaj kev sib txig sib luag nrog kev sib raug zoo tsawg.
4. Kev ua tau zoo heev nyob rau hauv hnyav ib puag ncig
LSAW cov kav dej yog tsim los tiv thaiv huab cua xws li:
Qhov kub tsis tshua muaj nyob hauv cheeb tsam arctic
Siab -siab tob- hiav txwv ib puag ncig
Corrosive av thiab sulfide- nplua nuj roj teb
Lawv pom muaj zog tiv thaiv hydrogen-induced cracking thiab stress corrosion, tshwj xeeb tshaj yog thaum tsim rau X70 los yog X80 steel qib.
5.Tsim nyog rau High-Risk Zones
Raws li API cov qauv, LSAW kav yog covyam pom zoo xwb rau siv nyob rau hauv Chav Kawm 1 thiab Chav Kawm 2- nrog rau cov cheeb tsam nroog uas muaj neeg nyob coob, seabeds, thiab siab - thaj chaw txias-vim lawv muaj kev nyab xeeb zoo dua thiab muaj kev ntseeg tau zoo
6. Comprehensive Quality Control thiab Traceability
Cov txheej txheem tsim khoom suav nrog kev sim nruj: ultrasonic thiab X-ray tshuaj xyuas cov welds, kuaj cov cuab yeej cuab tam (tensile, impact, hardness), thiab tshuaj ntsuam xyuas cov ntaub ntawv raw. Qhov no ua kom muaj kev ua raws li cov qauv thoob ntiaj teb xws li API 5L, ISO 3183-3, thiab GB / T 9711 .
