Nyob rau hauv lub ntiaj teb steel yeeb nkab lag luam, tshwj xeeb tshaj yog nyob rau hauv cov roj thiab roj kis thiab offshore cov phiaj xwm kev ua yeeb yam,API 5LthiabAPI 2Byog ob tus qauv tseem ceeb thiab dav tau lees paub. Ob leeg raug muab los ntawmMiskas lub koom haum (API), tab sis lawv txawv nyob rau hauv lawv cov pob ntawm daim ntawv thov, cov kev xav tau, thiab ntsuas kev ua tau zoo. Nkag siab cov kev sib txawv no yog qhov tseem ceeb thaum xaiv cov khoom lag luam zoo rau koj qhov project.
API 5L: Tus Txheej Txheem Rau Roj Thiab Roj Txuas Kev Thauj
API 5LPuas yog thawj qhov tshwj xeeb rau cov kab hlau kav siv uas siv hauv kev thauj cov roj, roj, thiab dej dhau qhov kev ncua ntev. Nws siv rau ob qho tib siSeamless kav (SMLS)thiabWelded Kav(suav nrog ERW, LSAW, SSAW).
API 5L cais cov khoom rau hauv ob qib tshwj xeeb:
- PSL1 (Theem Khoom Tshwj Xeeb Qib 1): Cov cuab yeej siv khomob yooj yim, haum rau kev siv dav dav.
- PSL2 (Theem Khoom Tshwj Xeeb Theem 2): Qhov yuav tsum muaj tshuaj muaj tshuaj, cov khoom siv neeg kho tshuab, muaj kuab heev, thiab tsis yog- Kev sim tshuaj ntsuam. Nws tau siv nyob rau hauv kev thov ib puag ncig xws li ntug hiav txwv, siab {{2} {{{{Corrosion cov ntawv thov.
Cov khoom qib qis dua API 5L yog npe raws li qhov tsawg kawg nkaus ua lub zog (piv txwv li,Gr.B, X42, X60, X70, thiab lwm yam). Piv txwv li,X60yuav tsum muaj tsawg kawg yog lub zog ntawm 60 ksi (kwv yees li ntawm 415 MPa).
Cov tseev kom tseem ceeb ntawm API 5L suav nrog:
- Tshuaj Muaj Tshuaj: Txwv nruj txwv rau cov ntsiab lus xws li C, MN, P, S, thiab SI.
- Cov Khoom Siv Neeg Kho Tshuab: Tso lub zog, tawm lub zog, elongation, thiab charpy v - tsis muaj kev ntsuam xyuas.
- Qhov seem ntev: Tswj dhau OD, Phab Ntsa Thickness, thiab ovality.
- Weld Seam Zoo: 100% Ultrasonic kev xeem; Kev tshuaj ntsuam puas yuav tsum muaj rau qee qhov haujlwm.
- Hydrostatic Kuaj thiab Pom Kev Pom: Ua kom xau dej - ntaub ntawv ua haujlwm thiab tsos.
Ua tsaug rau nws cov qauv txheej txheem phom sij thiab kev soj kev saws hauv ntiaj teb,API 5L yog tus qauv raj xa dejRau cov roj thiab roj ua haujlwm thoob ntiaj teb.
API 2B: Kev tsim khoom tshwj xeeb rau cov txheej txheem ntug dej
Tsis zoo li API 5L,API 2Byog tsom rauCov Khoom Siv Pov Tsegsiv nyob rau hauv cov txheej txheem ntug hiav txwv. Nws cov npe tag nrho yog"Welded xaus, dov nplhaib thiab forged steel qauv yeeb nkab cov khoom siv rau kev tawm tsam."Cov qauv no siv rau cov qauv yeeb nkab cov khoom siv tau siv hauv cov roj hluav taws xob, pob khaus, thiab pawg ua haujlwm} Tsis yog kav dej rau cov kua tsheb thauj.
API 2B hais txog:
- Cov Txheej Txheem Kev Ncaj Ncees thiab Weld Zoo
- Cov Txheej Txheem Kho Mob Thermal Kho Mob (Post - Weld Kev Kho Tshav Kub)
- Qhov tseeb ntawm qhov tseeb ntawm cov khoom loj
- Vuam cov txheej txheem tsim nyog thiab kev sib tw
- Kev ua tau zoo nyob rau hauv dynamic chaw thau khoom thiab marine ib puag ncig
Tsis zoo li API 5L, API 2B puastsisThov rau cov kav dej siv rau kev thauj khoom siab. Nws lub ntsiab lus yog kev ua tau zoo, suav nrog kev tiv taus kev qaug zog, yoj kev cuam tshuam, thiab corrosion hauv ntug dej hiav txwv.

Yuav ua li cas xaiv txoj cai txheem?
Yog tias koj tes num cuam tshuam nrog kev thauj mus los ntawm roj, ntuj, lossis dej -}} qhov kev siv siab}-API 5Lyog tus qauv koj yuav tsum ua raws. Nws ua kom cov yeeb nkab cov tshuab thiab cov tshuaj lom neeg lom neeg, tseem ceeb rau cov tshuab thauj roj.
Rau cov txheej txheem ntawm ntug dej, xws li pob khaus, risers, thiab cua lub hauv paus, qhov twgTxheej Txheem Txheej Txheemyog thawj qhov kev txhawj xeeb ntau dua li muaj lub zog muaj zog,API 2Byog tus qauv raug.
