Vim li cas Kev Lag Luam Roj thiab Roj Siv Carbon Steel Pipes

1. Muaj zog thiab kav ntev

Cov yeeb nkab carbon steel muaj npe nrov rau lawv lub zog tensile zoo heev. Nyob rau hauv cov roj sib sib zog nqus thiab cov roj reservoirs uas muaj siab heev (txog 70-140 MPa), carbon steel kav muaj:

High yield zog (Ntau tshaj los yog sib npaug rau 240-550 MPa);

Zoo heev tiv thaiv rau sab hauv siab tawg;

Zoo toughness thiab qaug zog kuj.

2. Tus nqi -Kev daws teeb meem zoo

Piv nrog rau cov hlau tsis muaj steel lossis lwm yam alloys, cov kav dej carbon steel siv hauv kev lag luam roj thiab roj tsuas yog 20-40% ntawm lawv cov nqi yam tsis muaj kev cuam tshuam kev ua haujlwm. Lawv ua tau raws li feem ntau cov roj thiab roj ua haujlwm, thiab kev tiv thaiv corrosion tuaj yeem txhim kho los ntawm cov txheej txheem. Lawv kuj yooj yim dua rau vuam thiab nruab rau hauv lub tshav pob.

3. Corrosion Resistance

Nrog rau cov txheej txheem tsim nyog thiab kev kho mob, cov kav dej carbon steel tuaj yeem tiv taus qhov hnyav ib puag ncig, suav nrog kev sib tsoo ntawm ntug dej hiav txwv thiab siab - daim ntawv thov kub.

4. Kev siv dav dav

Cov pa roj carbon steel kav yuav luag txhua qhov kev lag luam roj thiab roj:

Cov cuab yeej tswj tau zoo;

Lub cevthiab tubing (OCTG);

Onshore / subsea roj thiab roj pipelines;

Cov khoom siv hluav taws xob cov kav dej;

LNG, thee chemical, thiab petrochemical engineering.

Hom Hom Carbon Steel Pipes hauv Kev Lag Luam Roj thiab Roj

1. Seamless steel kav

Zoo tagnrho rau siab - cov ntawv thov siab vim lawv cov qauv tsis sib xws.

2. Welded steel kav

Haum rau nruab nrab thiab qis -siab tshuab, nqi- zoo.

3. Resistance Welded (ERW) Cov kav hlau

Siv rau cov qauv thiab qis - thauj cov kua dej.

Rau cov kev xav tau tshaj plaws ntawm kev ua haujlwm roj thiab roj, cov kav dej seamless carbon steel feem ntau yog qhov kev xaiv thawj zaug vim lawv lub zog zoo dua thiab ua kom tawg- pov thawj kev ua haujlwm.

Daim ntawv thov ntawm Carbon Steel Pipes nyob rau hauv Roj thiab Gas Extraction

1. Zoo Casing Yeeb thiab Tubing

Cov pa roj carbon steel kav yog siv los ua kab hauv lub qhov dej, txheej txheem hu ua casing siv, uas tiv thaiv lub qhov dej hauv av thiab tiv thaiv cov dej hauv av los ntawm kev sib kis. Tubing yog siv los thauj cov roj thiab roj rau saum npoo.

2. Directional Drilling

Niaj hnub nimno qhov tob tob thiab shale gas qhov dej feem ntau siv kab rov tav lossis ntau-txoj kev taw qhia drilling. Cov pa roj carbon steel kav yuav tsum tiv taus: torsional, tensile, dabtsi yog khoov kev nyuaj siab, tsis tu ncua kev co, thiab cuam tshuam.

Kev siv cov Carbon Steel Pipes nyob rau hauv cov roj thiab roj tsheb thauj mus los

1. Pipeline Networks

Cov kav dej dav dav, qee zaum ncab ntau txhiab mais, yog tsim los siv cov kav dej carbon steel. Cov tes hauj lwm no thauj cov roj av, roj av, thiab cov khoom siv roj ua kom zoo los ntawm cov chaw tsim khoom mus rau cov chaw tsim khoom thiab cov chaw faib khoom.

2. Cov kav dej hauv qab hiav txwv

Kev thauj cov roj thiab roj los ntawm ntug dej hiav txwv mus rau cov chaw nyob rau sab ntug dej yuav tsum muaj cov kav dej hauv qab hiav txwv.

Carbon steel pipelines yog cov khoom ntawm kev xaiv rau cov ntawv thov no vim lawv muaj peev xwm tiv taus siab thiab corrosive marine ib puag ncig.

3. Kev tu thiab kev nyab xeeb

Kev saib xyuas niaj hnub thiab kev kuaj xyuas kev ncaj ncees yog qhov tseem ceeb rau kev ua haujlwm nyab xeeb ntawm cov kav dej.

Cov pa roj carbon steel pipelines paub txog lawv cov kav ntev, pab txo qis kev txij nkawm thiab cov nqi, yog li txhim kho kev ua haujlwm tag nrho.

Kev siv cov Carbon Steel Pipes nyob rau hauv Roj thiab Gas Refining

1. Distillation Units

Roj Crude yog rhuab thiab sib cais mus rau hauv ntau yam Cheebtsam nyob rau hauv distillation units.

Carbon steel pipelines yog lub luag hauj lwm rau kev thauj cov khoom no smoothly los ntawm ntau theem ntawm refining thiab tswj lawv cov kev ncaj ncees nyob rau hauv huab mob.

2. Hydrocracking thiab Catalytic Cracking

Cov txheej txheem refining no tawg loj hydrocarbon molecules rau hauv me me, muaj txiaj ntsig zoo dua molecules.

Qhov siab - ib puag ncig siab ntawm cov chav tsev no xav tau kev siv cov kav dej carbon steel ntev.

3. Kev nyab xeeb thiab ua haujlwm tau zoo

Kev ntseeg siab ntawm cov pa roj carbon steel kav ua kom cov haujlwm du ntawm cov txheej txheem refining, txo qhov kev pheej hmoo ntawm kev xau lossis ua haujlwm tsis zoo.

Qhov no txhim kho kev nyab xeeb thiab kev ua haujlwm zoo, uas yog qhov tseem ceeb hauv kev ua kom zoo dua qub.
