GB / T 8163 Seamless Steel Yeeb Nkab: Tus Qauv Txheej Txheem Rau Kev Pab Cuam Siab Thiab Ua Kua Dej

GB/T 8163 txhais cov kev cai rau kub - dov los yog txias - kos seamless carbon thiab alloy steel kav npaj rausiab piping systems. Nws lub ntsiab philosophy yogkev ruaj ntseg kiag nyob rau hauv siab ntim. Txhua yam ntawm kev tsim khoom, los ntawm steelmaking mus rau qhov kawg kev soj ntsuam, yog npaj rau kev tiv thaiv tsis ua hauj lwm nyob rau hauv kev ntxhov siab nyob rau hauv, ua rau nws fundamentally txawv los ntawm cov qauv qauv xws li GB / T 8162.

Cov qauv no yog qhov tsis tseem ceeb hauv kev lag luam uas cov kav dej tsim cov kab ke rau cov txheej txheem tseem ceeb:

• Kev tsim hluav taws xob:Boiler tubes, superheater thiab reheater coils, thiab siab -siab cov kab hauv thermal fais fab nroj tsuag.
• Petrochemical & Roj & Roj:Cov txheej txheem piping, refinery pipelines, thiab cov kab xa mus rau hydrocarbons, chemicals, thiab feedstocks.
• Boiler kev tsim khoom:Cov khoom tseem ceeb rau cov dej- cov phab ntsa, cov khoom siv hluav taws xob, thiab lwm qhov chaw siab hauv cov khoom siv hluav taws xob thiab hluav taws xob boilers.
• Thaum tshav kub kub Exchanger & Condenser Tubes:Qhov twg cov hlab yuav tsum tiv nrog lub siab thiab feem ntau sab nraud corrosion.
• General High -Kev Pabcuam Siab:Txhua qhov cog piping system tsim los ua haujlwm nyob rau hauv lub siab tseem ceeb.

Qib xaiv nyob ntawm qhov kev pabcuam siab, qhov kub thiab txias, thiab ib puag ncig corrosion. Cov qib uas tau muab ntau tshaj plaws suav nrog:

• Cov pa roj carbon steel:

20 # Hlau:Qib workhorse rau kev pabcuam dej dav dav ntawm qhov kub thiab txias. Muab qhov sib npaug zoo ntawm lub zog, weldability, thiab tus nqi.

• Tsawg-Alloy Steels:

Q345 (Zoo li ASTM A53 / API 5L Gr. B):Muab cov khoom muaj zog ntau dua rau cov ntawv thov siab dua lossis tso cai rau cov phab ntsa nyias.

Alloy Qib (piv txwv li, 15CrMoG, 12Cr1MoVG):Tshwj xeeb rau siab - qhov kub thiab txias (piv txwv li, boiler superheaters). Cov chromium-molybdenum steels no muaj kev txhim kho creep zog thiab oxidation tsis kam.

Kev ua raws li GB / T 8163 yog txhais los ntawm nws cov txheej txheem validation nruj. Cov ntsiab lus tseem ceeb suav nrog:

• Hydrostatic Test: Qhov no yog qhov yuav tsum tau ua, tsis yog -kev sim sib tham.Txhua cov yeeb nkab yuav tsum raug kuaj rau lub siab (xws li los ntawm cov qauv uas muaj cov qib steel, phab ntsa tuab, thiab txoj kab uas hla) rau lub sijhawm yam tsawg kawg nkaus uas tsis muaj qhov xau lossis tsis muaj deformation.
• Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):Tag nrho cov yeeb nkab lub cev yuav tsum tau kuaj xyuas kom pom qhov tsis xws luag. Cov txheej txheem muaj xws li:
• Kev kuaj ultrasonic (UT):Txheeb xyuas qhov tsis zoo ntawm sab hauv thiab subsurface.
• Eddy Current Testing (ET):Muaj txiaj ntsig zoo rau kev tshawb pom qhov chaw thiab ze rau - qhov chaw tsis zoo.
• Mechanical thiab Chemical Tests:Kev ntsuam xyuas tensile, kev ntsuam xyuas hardness, thiab tshuaj ntsuam xyuas tshuaj yog ua ib batch kom ntseeg tau tias cov khoom muaj raws li cov qib teev tseg.
• Strict Dimensional & Quality Control:Kev kam rau siab rau OD, WT, thiab qhov ncaj yog nruj tswj xyuas kom haum- nyob rau hauv cov kav dej tseem ceeb.

Xaiv cov khoom raug GB/T 8163 yog kev nyab xeeb- txheej txheem tseem ceeb:

• Paub meej tias Daim Ntawv Thov yog rau Siab:Cov qauv no yognkaus xwbrau pressurized kua systems.
• Txhais cov kev pab cuam:Txiav txim siab qhov kev khiav hauj lwm siab, qhov kub thiab txias, thiab hom kua dej (tshwj xeeb tshaj yog corrosiveness) los xaiv cov qib steel tsim nyog (piv txwv li, 20# rau ambient chav, 15CrMoG rau siab -kub chav).
• Qhia qhov yuav tsum tau kuaj:Thaum hydro thiab NDT yog tus qauv, qhia meej yog tias muaj kev sim ntxiv (xws li, Charpy impact test for low-temperature service) xav tau.
• Demand Complete Certification:CovMill Test Certificate (MTC)yog koj daim ntawv pov thawj ntawm kev ua raws cai. Nws yuav tsum suav nrog hydrostatic test siab, NDT txoj kev (xws li, UT), thiab tag nrho cov tshuaj lom neeg / cov txiaj ntsig.

Q1: Dab tsi yog qhov sib txawv tseem ceeb ntawm GB / T 8163 thiab GB / T 8162?
A:CovYuav tsum ntsuas hydrostatic siab thiab tag nrho - lub cev NDT tshuaj xyuasyuav tsum tau los ntawm GB/T 8163. GB/T 8162 cov kav dej tsis ua raws li cov kev ntsuas siab ncaj ncees. Lawv tsis yog interchangeable.

Q2: Peb puas tuaj yeem siv qib siab dua - cov khoom siv qib siab los ntawm GB / T 8162 (xws li Q345) ua cov yeeb nkab siab?
A: Tsis yog.Qib tsuas yog ib qho xwb. Ib lub yeeb nkab yuav tsum tau tsim, sim, thiab tau ntawv pov thawj rau lubsiab yeeb nkab txheem(GB/T 8163) yuav tsum suav hais tias muaj kev nyab xeeb rau kev pabcuam siab, tsis hais nws lub zog ntawm cov khoom siv.

Q3: GB / T 8163 cuam tshuam li cas rau cov qauv thoob ntiaj teb xws li ASTM A106?
A:GB / T 8163 yog lub teb chaws Suav ncaj qha sib npaug rau ASTM A106 rau carbon steel siab kav. Qib 20 # nyob rau hauv GB / T 8163 feem ntau suav hais tias ua haujlwm sib npaug rau ASTM A106 Qib B thiab tau txais dav hauv cov haujlwm thoob ntiaj teb.

Q4: Puas yog tag nrho GB / T 8163 cov kav dej haum rau siab -kev pabcuam kub?
A:Tsis yog. Cov qib carbon steel qib (20#, Q345) yog rau qhov kub thiab txias. Rau kev ua haujlwm siab - qhov kub thiab txias (piv txwv li, siab dua 450 degree), cov qib alloy steel tshwj xeeb xws li 15CrMoG, uas yog ib feem ntawm GB / T 8163, yuav tsum tau teev tseg.

GB / T 8163 tsis yog tsuas yog cov khoom specification; nws yog ib qho kev ruaj ntseg ruaj ntseg rau txhua lub tshuab ua kua dej. Nws cov txheej txheem nruj ua kom ntseeg tau tias txhua qhov 'meter' ntawm cov yeeb nkab xa cov kev ua tau zoo hauv kev ntxhov siab.
