API yeeb nkab vs 3PE yeeb nkab

Hauv cov haujlwm tseem ceeb xws li roj, roj av, thiab cov dej hauv nroog, cov kav dej ua haujlwm tseem ceeb ntawm kev thauj mus los, thiab lawv cov kev xaiv ncaj qha txiav txim siab qhov project txoj kev nyab xeeb, kev lag luam, thiab kav ntev. API yeeb nkab thiab 3PE yeeb nkab, ob qho khoom siv dav siv hauv cov kav dej, feem ntau yog cov thawj coj los ntawm pawg engineering. Txawm li cas los xij, lawv sib txawv hauv cov qauv tsim, cov yam ntxwv ntawm kev ua haujlwm, thiab cov xwm txheej siv tau. Kev nkag siab zoo txog lawv cov yam ntxwv yog qhov tseem ceeb rau kev txhim kho qhov project zoo.

Txhais thiab Core Application Scenarios

API yeeb nkab, luv luv rau "American Petroleum Institute Standard Steel Pipe," yog tsim raws li cov qauv thoob ntiaj teb xws liAPI 5L steel yeeb nkab. Nws yog tsim los ntawm high-strength steel thiab tsim los ntawm seamless dov los yog vuam txheej txheem. Nws lub zog tseem ceeb nyob hauv nws lub zog siab thiab tensile lub zog, ua rau nws siv dav hauv cov ntawv thov siab xws li cov roj thiab cov kav dej ntev ntev thiab cov shale gas wellhead manifolds. Nws cov qauv kev ruaj ntseg nyob rau hauv huab cua kub xws li -40 ° C mus rau 120 ° C ua rau nws yog ib qho tseem ceeb ntawm kev thauj mus los ntawm lub zog.

3PE yeeb nkab stands rau "peb-txheej polyethylene anti-corrosion steel yeeb nkab." Nws siv cov yeeb nkab steel zoo tib yam ua lub hauv paus, coated nrog peb-txheej txheej tiv thaiv corrosion uas muaj epoxy hmoov txheej (FBE), nplaum, thiab polyethylene. Nws cov qauv tsim tshwj xeeb tsom rau kev tiv thaiv corrosion, cuam tshuam rau cov yeeb nkab txoj kev pab cuam lub neej los ntawm kev cais cov kab mob hauv av thiab cov electrolytes los ntawm cov yeeb nkab steel. Nyob rau hauv ib puag ncig corrosive heev xws li dej hauv nroog, dej phwj tuaj kho, thiab kev thauj mus los ntawm cov kua tshuaj, 3PE yeeb nkab tuaj yeem ua tiav lub neej kev pab cuam ntau tshaj 50 xyoo, ua rau nws muaj pov thawj los tiv thaiv corrosion rau kev tsim kho hauv av.

Kev sib piv tseem ceeb

Los ntawm qhov kev ua tau zoo tseem ceeb, ob lub kav dej kom meej meej sib txawv hauv lawv qhov chaw. Hais txog cov khoom siv kho tshuab, API yeeb nkab feem ntau muaj lub zog tawm los siab dua 355 MPa, nrog qee qib siab zog (xws liAPI 5L X80) ncav cuag 555 MPa, muaj peev xwm tiv taus kev khiav hauj lwm siab tshaj 10 MPa. 3PE yeeb nkab, ntawm qhov tod tes, tso siab rau lub hauv paus steel yeeb nkab rau lub zog, thiab cov txheej txheem tiv thaiv corrosion nws tus kheej tsis muaj peev xwm ua kom muaj peev xwm, ua rau nws tsim nyog rau kev thauj mus los nruab nrab thiab qis (feem ntau ≤4 MPa).

3PE kav dej muaj qhov zoo tshaj plaws hauv kev tiv thaiv corrosion. Lawv cov txheej txheem peb txheej tsim ib qho kev thaiv ob qho ntawm "kev cais lub cev + tshuaj tiv thaiv." Kev ntsuam xyuas ntsev tsuag qhia tau tias lawv qhov kev xeb yog tsuas yog 1/50 ntawm cov yeeb nkab steel hlau. ThaumAPI cov kav dejtuaj yeem tiv thaiv corrosion los ntawm galvanizing thiab pleev xim, lawv cov kev ua tau zoo hauv faus lossis underwater ib puag ncig tseem qis dua li ntawm 3PE kav dej, xav tau cov txheej txheem tiv thaiv cathodic ntxiv, uas ua rau cov nqi tsim nyog.

Xaiv cov tswv yim thiab kev lag luam Trends

Kev xaiv qhov project yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "scenarios haum": Yog hais tias qhov nruab nrab conveying yog high-pressure roj los yog roj, los yog cov kev khiav hauj lwm ib puag ncig muaj qhov kub thiab txias hloov, API kav yog nyiam, nrog steel qib xws li X65 thiab X80 raug matched rau lub siab ntsuas. Rau faus dej los yog tshuaj lom neeg thauj cov dej khib nyiab, 3PE kav yog ib qho kev xaiv pheej yig dua, thiab cov thickness ntawm cov txheej tiv thaiv corrosion yuav tsum tau kho raws li cov av corrosivity.

Txoj kev lag luam tam sim no yog mus rau "kev ua haujlwm fusion." Qee lub tuam txhab tau sib txuas cov khoom siv lub zog siab ntawm API yeeb nkab nrog peb txheej los tiv thaiv corrosion ntawm 3PE yeeb nkab los tsim "high-strength anti-corrosion composite yeeb nkab." Cov kav dej no ua tau raws li qhov xav tau ntawm kev sib kis tau zoo thiab kev tiv thaiv corrosion mus ntev. Cov kav dej no twb tau siv dav hauv kev tsim cov roj thiab cov roj sib sib zog nqus thiab cov dej sib txawv hauv cov dej sib txawv. Txoj hauv kev tshiab no muab cov kev daws teeb meem zoo dua rau kev tsim hluav taws xob pipeline.
