X70 PSL2 pipeline steel yog lub siab -lub zog, siab -toughness pipeline steel qib raws li API 5L tus qauv, tshwj xeeb yog tsim rau ntev-nruab deb, siab- kev thauj mus los ntawm lub zog xws li roj thiab cov nkev. Hauv API Spec 5L tus qauv, "X" sawv cev rau cov raj xa dej, thiab "70" sawv cev rau nws qhov tsawg kawg nkaus yield zog ntawm 70 ksi (kwv yees li 485 MPa). Hauv cov txheej txheem European, cov qib sib npaug yog feem ntau hu ua L485 lossis S485.
Tag nrho Pipeline Support: API 5L X70 PSL2 Pipes + Custom Coating + Field Joint Kits for Integrated LATAM Hubs.

Cov Lus Qhia Txog Kev Xaiv Qhov Ntog (Coating) Ntawm API 5L X70 PSL2 pipeline rau roj thiab roj
Onshore (Rainforests & Deserts): 3LPE (3-Layer Polyethylene)
Kev pom zoo:Zoo tagnrho rau cov av ntub Amazon Basin lossis pob zeb Andean struts. PE txheej txheej muab kev tiv thaiv zoo tshaj plaws tiv thaiv av kev nyuaj siab thiab puas thaum lub sij hawm rov qab.
Offshore (Deepwater & Saline): FBE + Internal Flow Txheej
Kev pom zoo:Rau Brazil txoj haujlwm offshore,Fusion Bonded Epoxy (FBE)muab tshuaj adhesion zoo heev. Ntxiv ibInternal kua Epoxy txheejtxo kev sib txhuam, ua kom cov roj ntws ua haujlwm tau zoo los ntawm 3-5%-ib qho ROI tseem ceeb rau cov neeg ua haujlwm.
Kev Ntsuas & Kev Tswj Xyuas Zoo (PSL2 Txuj) Ntawm API 5L X70 PSL2 Roj thiab roj xa cov yeeb nkab
Charpy V-notch Impact Test:Verified toughness ntawm0℃rau -45 degree, qhov tseem ceeb rau siab -qhov siab Andean pipelines qhov twg hmo ntuj kub poob.
100% Tsis yog-Kev Ntsuas Kev Ua Phem (NDT):Ultrasonic (UT) lossis Radiographic (RT) kuaj ntawm tag nrho cov vuam thiab cov yeeb nkab lub cev kom tshem tawm cov micro- tawg.
Kev Ntsuas Hydrostatic:Piece-los ntawm-cov khoom kuaj (feem ntau Ntau dua lossis sib npaug li 20.0 MPa) kom lav qhov kev sib khi hauv qab siab tshaj plaws ua haujlwm siab.
DWTT (Drop Weight Tear Test):Yuav tsum tau ua rau cov kav dej ntau dua lossis sib npaug li 20", kom ntseeg tau tias cov yeeb nkab tuaj yeem ntes cov kab tawg khiav hauv loj - txoj kab uas hla.
Ntim & Kev thauj mus los ntawm API 5L X70 PSL2 High Yield Line Pipes
Precision Bevel Protection:Rau X70 kav siv nyob rau hauv automated vuam, peb sivhnyav-lub luag haujlwm steel- cov khoom tiv thaiv yaslos tiv thaiv J-bevels.
UV-Resistant Wrapping:Kev xaiv xim dawb UV-pab qhwv ntsej los tiv thaiv FBE txheej degradation thaum lub sij hawm ntev kev lis kev cai nyob rau hauv cov chaw sov so.
ISPM 15 Kev Ua Raws Cai:Tag nrho cov ntoo dunnage thiab bracing yog kub- kho thiab IPPC- stamped los xyuas kom meejseamless kev lis kev cai clearancehauv Brazil thiab Chile.
Soft Lifting:Yuav tsum sivnylon slingslos tiv thaiv kev khawb ntawm cov tshuaj tiv thaiv -corrosion txheej.
