ASME SB407 UNBIES N08810000810 NUM COV NEEG RAU OFFHEHORE ROJ THIAB GAS PLATALLS
For offshore oil and gas platforms, ASME SB407 UNS N08810 (Incoloy 800H) pipes are highly regarded for their high strength, durability, and robust corrosion resistance in extreme high-temperature and high-pressure environments. Txawm li cas los xij, xaiv cov kav dej no yuav tsum tau ua tib zoo saib xyuas lawv cov peev txheej tshwj xeeb thiab tsim khoom lag luam.
Dab tsi yog N08810?
UNS N08810 refers to Incoloy 800H, a high-temperature, corrosion-resistant nickel-iron-chromium alloy known for its excellent strength, oxidation resistance, and carburization resistance. Piv nrog rau hauv paus loj 800, nws muaj cov ntsiab lus muaj roj carbon ntau dua thiab cov cim tswj cov txhuas thiab cov ntsiab lus titanium. Cov alloy no yog tsim nyog rau kev thov cov ntawv thov xws li kev ua petrochemical, thiab muaj kev sib raug zoo nyob rau hauv txoj kev muaj zog, siab {}}} qhov chaw dej sov.

Offshore Daim Ntawv Thov Kev Ua Haujlwm
Kev kub siab thiab muaj kev kub siab: Lub Platform Offshore feem ntau siv cov raj xa khoom uas siv siab kub {} {} kev hloov pauv kub thiab cov piping cua sov. Lub zog thiab kev ruaj khov ntawm incoloy 800h ua kom nws zoo -} haum rau cov neeg xav tau no.
Cov peev txheej siab: Seamless incoloy 800h piping muaj cov zog hloov kho tshuab, suav nrog kev tuav lub siab sab hauv kev lag luam ntawm ntug hiav txwv. Nws cov kev tsim tawm ua se tau ntxiv ua rau cov kev siab no - bearing muaj peev xwm.
Txo cov thermal kev ntxhov siab: lub alloy tsawg kawg thermal expension txo qhov kev pheej hmoo ntawm kev pheej hmoo ntawm kev muaj kev ntxhov siab corrosion, yog li kev txhim kho kev nyab xeeb thiab kev pabcuam lub neej.
Tiv thaiv rau cov txheej txheem tshwj xeeb: cov khoom siv tsis kam mus rau carburizance thiab oxidizing rau roj floling thiab thauj mus los ntawm cov pa hluav taws.
Fabrication thiab kev sim
Vuam: Incoloy 800h tuaj yeem welded siv cov txheej txheem vuam xws li tsov, ntshav, ntshav, thiab pas nrig arc vuam. Careful attention must be paid to controlling heat input and impurity contamination (sulfur, phosphorus, nitrogen, and oxygen) to prevent hot cracking. Cov tsav tsim nyog tau los tswj Weld kev ncaj ncees.
Txoj kev sib sau: Cov ntaub ntawv pov thawj ua tau zoo thiab tuaj yeem tsim tau siv ntau txoj kev tsis muaj kev cuam tshuam kev cuam tshuam lub zog. Txawm li cas los xij, vim nws cov qauv grain, cov khaub thuas loj tuaj yeem ua rau muaj "txiv kab ntxwv tev" tsos.
Kev xeem: Cov xov tooj yuav tsum tau ntsuas kom tau raws li ASME SB407 thiab cov kev xav tau ntawm Wremore.
Kev Kuaj Me: Tensile Zog, tawm lub zog, elongation lub zog, thiab cov nplej loj yuav tsum tau raws li cov kev tshwj xeeb. Grain loj yog ntsuas siv cov qauv phiajcar.
Nondestructive ntsuam xyuas (NDT): Cov ntawv thov tawm tsam feem ntau yuav tsum tau 100% Hydrostatic Kev Kuaj: Cov kav dej yias hydrostatic kuaj kom paub meej tias lawv lub peev xwm los tiv thaiv sab hauv siab.
Cov khoom xeem ntawv (MTC): Cov ntaub ntawv xws li EN 10204 / 3.1B daim ntawv pov thawj yog qhov tseem ceeb rau kev lees paub tshuaj lom neeg cov khoom siv thiab cov neeg kho mob.
GNee steel tshwj xeeb hauv kev tsim cov nickel - raws li alloys. Gnee Steel cov khoom ntim khoom lag luam muaj cov khoom lag luam hlau: cov kav dej nrog cov kab yeeb yaj kiab uas tsis muaj xeb, thiab tsawg dua yog kev nyab xeeb nrog cov steel strapping. Cov thawv ntoo / crates: kav ib txwm ntim hauv cov thawv ntoo lossis crates los tiv thaiv lawv thaum lub sijhawm tsheb thauj mus los, tshwj xeeb yog diameters. Seaworthy export ntim: Cov chaw muag khoom siv cov txheej txheem seaworthy export export cov ntaub ntawv sau thiab cov tswv yim los tiv thaiv cov kav dej thaum lub sijhawm thauj mus los. Tarpaulin Ntim: Qhov no tiv thaiv nag, hiav txwv dej hiav txwv, thiab lwm yam sab nraud sab nraud los ntawm kev nkag ntawm cov chaw ntoo sib tsoo thaum lub tsheb thauj khoom thaum export thaum thauj khoom. GNEE steel tshwj xeeb hauv kev tsim khoom thiab muag khoom ntawm alloy cov ntaub ntawv. Gnee Steel cov khoom yog dav siv nyob rau hauv Aerospace, tshuaj lom neeg, siv hluav taws xob, thiab peb tuaj yeem muab zog alloymy cov kev daws teeb meem raws li cov neeg siv khoom xav tau. Rau aluminium cov khoom siv nqe lus los yog customized alloy cov kev daws teeb meem, thov hu rau peb rau ib nqe lus ntawmss@gneesteel.com.
