Qhov txawv ntawm API 5L X52 thiab Qib B yog dab tsi

Hauv thaj tsam ntawm kab yeeb nkab,API 5L Qib B (Gr.B)thiabAPI 5L X52yog ob feem ntau siv steel qib. Ob leeg ua raws liAPI Spec 5Lspecification luam tawm los ntawm American Petroleum Institute, tab sis lawv txawv heev nyob rau hauv lub zog, tshuaj muaj pes tsawg leeg, thiab daim ntawv thov.

API 5L Qib B (Gr.B) - Cov kav dej hauv paus

Qib B raug suav hais tias yog qib "baseline" lossis "standard" qib rau kab yeeb nkab. Nws yog qhov kev xaiv ntau tshaj plaws thoob ntiaj teb rau cov nroj tsuag petrochemical, kev kho dej, thiab qis - cov roj thiab roj sib sau ua ke.

Mechanical Properties:

Yam tsawg kawg nkaus Yield Strength245 MPa (35,500 psi).

Yam tsawg kawg Tensile Strength415 MPa (60,200 psi).

Khoom yam ntxwv: Feem ntau yog Carbon dawb -Manganese hlau. Vim tias qhov kev xav tau ntawm lub zog qis dua, cov ntsiab lus carbon yog yooj yim los tswj, ua rauzoo heev weldabilitythiab formability.

Daim ntawv thov:

Internal piping nyob rau hauv cov roj refineries.

Tsawg-cov roj, roj, thiab cov dej sib sau ua ke / tsheb thauj mus los.

Kev siv dej hauv nroog thiab kev siv dav dav.

Qhov zoo: Tsawg tus nqi, yooj yim rau qhov chaw, thiab kev ua haujlwm tsawg.

 

API 5L X52 - Siab-Test Line Pipe

X52 belongs rau qeb "High-Test" qeb. Tus "X" sawv cev rau lub zog siab, thiab tus naj npawb "52" qhia tias qhov tsawg kawg nkaus lub zog ntawm 52,000 psi.

Mechanical Properties:

Yam tsawg kawg nkaus Yield Strength360 MPa (52,200 psi).

Yam tsawg kawg Tensile Strength460 MPa (66,700 psi).

Khoom yam ntxwv: Txhawm rau ua tiav lub zog siab dua thaum tuav lub zog, X52 feem ntau ntxiv cov lej ntawm cov khoom sib xyaw (xws liNiobium Nb, Vanadium V, lossis Titanium Ti). Cov txheej txheem no hu ua "micro-alloying."

Daim ntawv thov:

Ntev-nruab deb, siab- cov roj crude thiab cov pa roj carbon monoxide kis tau tus mob trunklines.

Tej yaam num yuav tsum tau txo cov yeeb nkab hnyav los yog nyias phab ntsa thickness.

Complex teb tsim ib puag ncig.

Qhov zoo: Vim X52 yog kwv yees li47% muaj zog duatshaj Qib B, nws tso cai rau athinner phab ntsa thicknessnyob rau hauv tib lub siab. Qhov no txo ​​qis kev siv steel, tus nqi thauj khoom, thiab tus nqi vuam xav tau ntawm -site.

FAQ

API 5L X52 sib npaug li cas?

Qhov tseeb tshaj plaws thiab niaj hnub sib npaug yogTS EN ISO 3183 L360.

Hauv xyoo 2000s, API thiab ISO sib haum nrog lawv cov qauv.

API 5L X52yog zoo tib yam liISO 3183 Qib L360.

Lub "L" sawv cev rau Kab Yeeb, thiab "360" yog hais txog lub zog tawm los hauv MegaPascals (MPa).

 

API 5L Qib B siv rau dab tsi?

API 5L Qib Byog feem ntau "general-hom phiaj" kab yeeb nkab qib, feem ntau siv hauvqis-rau- nruab nrab siabib puag ncig.

Kev siv tseem ceeb:

Roj thiab roj sib sau ua ke: Kev thauj cov roj av los yog cov nkev ntuj los ntawm lub qhov dej mus rau cov tso tsheb hlau luam lossis cov chaw ua haujlwm thawj zaug.

Refineries thiab tshuaj nroj tsuag: Sab hauv qis- cov txheej txheem siab piping nyob rau hauv cov chaw ua haujlwm.

Kev thauj mus los hauv dej: Cov dej hauv nroog, cov kav dej, thiab cov kav dej txias.

Kev siv tus qauv: Siv rau kev tsim kho piling, tiv thaiv casing, los yog kev txhawb nqa.
