kuaj thiab tshuaj xyuas ntawm API 5L X60 PSL2 Pipeline rau roj thiab roj
Basic Performance Testing (PSL2 Yuav Tsum Tau):
Chemical Composition: nruj me ntsis tswj cov pa roj carbon sib npaug (CEq Tsawg dua los yog sib npaug rau 0.43) kom ntseeg tau tias weldability nyob rau hauv high humidity ib puag ncig ntawm South America.
Tension thiab Yield Strength: Xyuas kom X60 qib mechanical stability.
Cryogenic Impact (CVN): Rau yav qab teb South America (xws li Patagonia) lossis dej hiav txwv sib sib zog nqus, yuav tsum tau ntsuas qhov ntsuas ntawm 0℃lossis -10 degree.
Thick-Tshiab Phab Ntsa Yeeb Nkab Tshwj Xeeb Kev Tshuaj Xyuas (NDT - Tsis yog-Kev Ntsuas Kev Ntsuas):
100% Full-Body Ultrasonic Testing (UT): For pipes with a wall thickness >25mm, xyuas cov kev suav nrog thiab delamination tsis xws luag.
Strict Geometric Dimension Control: Tsom ntsoov rau kev tshuaj xyuas cov yeeb nkab kawg roundness (tawm - ntawm - roundness). Tsis siv neeg vuam tshuab rau ntawm ntug dej hiav txwv pipelaying hlab ntsha muaj siab heev roundness kam rau ua (feem ntau zoo dua li API qauv).
Environmental adaptability testing (rau acidic oil and gas fields):
HIC (hydrogen{0}}induced cracking resistance) & SSCC (sulfide stress cracking resistance): Rau cov haujlwm hauv "acidic environments" uas muaj hydrogen sulfide hauv Colombia lossis Venezuela.
API 5L X60 PSL2 Seamless Yeeb Nkab rau cov pa roj ntim & tiv thaiv
Kev xa khoom los ntawm Asia mus rau South American cov chaw nres nkoj (xws li Santos lossis Georgetown) yuav siv sijhawm 40-50 hnub, thaum lub sijhawm cov kav dej yuav tsum tiv taus qhov kub thiab txias, cov av noo siab, thiab cov ntsev ntsev ntau thoob plaws hauv txoj kab nruab nrab.
Yeeb Nkab Txheej:
Sab nrauv: Siv tsawg kawg 300μm ntawm cov tshuaj tiv thaiv dub - xeb kua roj vanish; 3LPE (onshore) lossis 3LPP (offshore) txheej yog muaj nyob ntawm qhov yuav tsum tau ua.
Sab hauv: Rau cov kav dej roj, cov kua epoxy rub -txo cov txheej tuaj yeem siv tau.
Heavy-duty End Protectors:
Hnyav-lub luag haujlwm steel- cov kaus mom kawg (Steel-Plastic Composite): Cov kaus mom pheej yig yas raug txwv nruj heev. Ib qho tuab tuab - cov yeeb nkab phab ntsa tuaj yeem hnyav ntau tons; Lub kaus mom yas zoo tib yam yuav tawg tam sim ntawd thaum lub sij hawm hoisting, ua rau kev puas tsuaj rau lub bevel.
Ua ntej- kev teeb tsa ntawm Kev Siv Slings:
Ua ntej-nruab Nylon Lifting Slings: Slings yog ua ntej- ntsia rau ntawm txhua cov yeeb nkab kom yooj yim rau kev ua haujlwm forklift ncaj qha ntawm South American chaw nres nkoj, tiv thaiv kev sib cuag ncaj qha ntawm cov hlua hlau thiab cov yeeb nkab lub cev thiab muaj peev xwm ua rau muaj kev puas tsuaj los tiv thaiv - txheej txheej.
Drying thiab Sealing:
Lub pob ntawv desiccant tau muab tso rau hauv cov yeeb nkab, thiab cov yeeb nkab kawg yog ob npaug - qhwv nrog siab - lub zog tsis muaj dej tsis zoo (yog tias muaj cov kev cai tshwj xeeb rau sab hauv phab ntsa).
Kev thauj mus los ntawm API 5L X60 PSL2 pipelines rau cov kua dej uas muaj hluav taws kub:
Shipping txoj kev xaiv
- Breakbulk: Nyiam rau qhov ntim loj ntawm cov kav dej ntev (12m DRL). Xyuas kom cov kav dej tau khaws cia "hauv qab lawj" txhawm rau tiv thaiv cov dej hiav txwv ncaj qha.
- Ntim: Tsuas yog tsim rau cov ntim me me lossis cov kav dej luv (6m SRL). Siv cov khoom siv plywood reinforced rau kev txhawb nqa los tiv thaiv cov tuab - cov kav dej hauv cov kav dej los ntawm crushing hauv pem teb.
Lashing & Securing:
- Hlau -dawb: Fumigated ntoo yuav tsum tau siv los cais cov kav dej ntawm ib leeg thiab los ntawm lub nkoj tuav kom tiv thaiv electrochemical corrosion los ntawm kev sib txhuam.
- Multi-cov ntsiab lus ntxiv: Siv cov hlua tshwj xeeb thiab cov tensioners rau tus ntoo khaub lig- zoo li kev ruaj ntseg kom tsis txhob muaj kev hloov pauv thaum lub caij ntuj sov huab cua thaum hla dhau Cape Horn lossis ncig lub Cape of Good Hope.
