A252 Qib 2 Hlau Yeeb Nkab Pilings rau Cov Hauv Paus Hauv Kev Lag Luam Offshore
Nyob rau hauv lub ntiaj teb niaj hnub hloov zuj zus ntawm kev tsim kho vaj tse, kev xav tau ntawm cov khoom siv ruaj khov thiab ruaj khov yog qhov tseem ceeb. Peb zoo siab los muab peb cov nqi them nqi, tsim kom tau raws li cov qauv nruj uas yuav tsum tau muaj rau cov kav dej hauv av. Peb pawg yog tsim los nrog precision, kom ntseeg tau tias txhua pawg yog tus kheej hnyav los lav kev ua raws li kev lag luam specifications.
Peb cov yeeb nkab yeeb nkab yog tsim los ntawm A252 GRADE 2 steel, cov khoom siv paub txog nws lub zog thiab kev ua haujlwm zoo. Qib no ntawm cov hlau no tshwj xeeb tshaj yog tsim rau cov ntawv thov nrog rau kev teeb tsa hauv av uas qhov kev ncaj ncees ntawm cov khoom tseem ceeb heev. A252 GRADE 2 steel yeeb nkab yog tsim los tiv thaiv cov xwm txheej hnyav uas feem ntau ntsib nyob rau hauv ib puag ncig hauv av, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv roj pipeline.
Raws li ib tug ntseeg stockist ntawm SSAW (Spiral Submerged Arc Welded) yeeb nkab, peb xyuas kom meej tias peb cov khoom ua tau raws li cov qauv zoo tshaj plaws. Txhua pawg yeeb nkab yog tsim los siv cov txheej txheem vuam siab heev uas ua rau cov khoom muaj zog thiab ruaj khov. Peb cov yeeb nkab SSAW paub txog nws cov cuab yeej zoo heev thiab tsim nyog rau ntau yam kev siv, suav nrog cov kav dej hauv av. Cov txheej txheem kauv vuam tsis tsuas yog muab cov qauv muaj zog, tab sis kuj tso cai rau cov khoom siv ntev ntev, txo qhov xav tau ntawm cov pob qij txha thiab txhim kho tag nrho kev ncaj ncees ntawm kev teeb tsa.

Permissible variations In Weights and Dimensions
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau hnyav nyias thiab nws qhov hnyav yuav tsum tsis txhob sib txawv ntau tshaj 15% tshaj lossis 5% raws li nws qhov hnyav, suav nrog nws qhov ntev thiab nws qhov hnyav ntawm ib chav tsev ntev.
Sab nraud txoj kab uas hla yuav tsum tsis txhob sib txawv ntau tshaj ± 1% ntawm lub npe nominal sab nraud txoj kab uas hla
Phab ntsa thickness ntawm txhua qhov chaw yuav tsum tsis pub ntau tshaj 12.5% raws li cov phab ntsa thickness
Ntev
Ib qho random ntev: 16 txog 25ft (4.88 txog 7.62m)
Ob chav random ntev: tshaj 25ft txog 35ft (7.62 txog 10.67m)
Uniform lengths: permissible variation ± 1in
Xaus
Cov yeeb nkab yuav tsum tau muab tso rau hauv qhov xaus, thiab cov burrs ntawm qhov kawg yuav raug tshem tawm.
Thaum cov yeeb nkab kawg tau teev tseg rau bevel xaus, lub kaum sab xis yuav tsum yog 30 txog 35 degree
Khoom cim
Txhua qhov ntev ntawm cov yeeb nkab pawg yuav tsum raug cim los ntawm stenciling, stamping, los yog dov los qhia: lub npe lossis hom ntawm cov chaw tsim khoom, cov xov tooj cua sov, cov txheej txheem ntawm cov chaw tsim khoom, hom helical seam, sab nraud txoj kab uas hla, nominal phab ntsa thickness, ntev, thiab qhov hnyav ntawm ib chav tsev ntev, qhov kev qhia tshwj xeeb thiab qib.
Ib qho tseem ceeb ntawm peb pawg yog lawv qhov hnyav sib xws. Txhua pawg yog ua tib zoo ntsuas thiab peb ua raws li kev ua haujlwm nruj kom ntseeg tau tias qhov hnyav tsis sib txawv los ntawm ntau dua 15% lossis 5% ntawm qhov ntsuas qhov ntsuas. Qhov tseeb no yog qhov tseem ceeb rau cov engineers thiab cov neeg cog lus uas tso siab rau qhov tseeb tshwj xeeb rau lawv cov haujlwm. Los ntawm kev tswj hwm cov qauv hnyav no, peb pab xyuas kom meej tias cov txheej txheem kev teeb tsa mus tau zoo thiab qhov kev ua tau zoo ntawm cov pawg ua tau raws li cov qauv xav tau.
Peb qhov kev cog lus rau kev ua tau zoo txuas ntxiv dhau ntawm kev tsim khoom. Peb nkag siab tias kev ua tiav ntawm txhua qhov haujlwm uas cuam tshuam nrog cov kav dej hauv av yog nyob ntawm kev ntseeg tau ntawm cov khoom siv. Yog li ntawd, peb ua cov kev tswj xyuas nruj nruj ntawm txhua theem ntawm kev tsim khoom. Peb pab pawg kws tshaj lij tau mob siab rau kom ntseeg tau tias txhua pawg ua tau raws li qhov tsim nyog tshwj xeeb thiab siv tau tam sim ntawd thaum xa khoom.
Ntxiv nrog rau cov pawg zoo, peb kuj muab kev pabcuam zoo rau cov neeg siv khoom thiab kev txhawb nqa. Peb pab neeg txawj ntse yeej ib txwm muaj los teb cov lus nug uas koj muaj, muab kev cob qhia, thiab pab koj xaiv cov khoom tsim nyog rau koj cov kev xav tau tshwj xeeb. Peb txaus siab rau peb tus kheej hauv kev tsim kev sib raug zoo nrog peb cov neeg siv khoom mus sij hawm ntev, kom ntseeg tau tias lawv tsis yog tsuas yog tau txais cov khoom lag luam thawj zaug xwb, tab sis kuj muaj kev txhawb nqa uas lawv xav tau kom ua tiav lawv qhov project.
Hauv cov ntsiab lus, peb cov yeeb nkab hwm zoo ua los ntawm A252 GRADE 2 steel, muaj los ntawm peb cov kev pabcuam SSAW yeeb nkab, yog qhov kev daws teeb meem zoo tshaj plaws rau koj qhov project hauv av. Nrog rau peb txoj kev cog lus rau kev ua tau zoo, qhov tseeb, thiab cov neeg siv khoom txaus siab, koj tuaj yeem tso siab rau peb los muab cov ntaub ntawv koj xav tau los xyuas kom meej tias koj qhov kev tsim kho vaj tse ua tiav thiab nyab xeeb. Xaiv peb cov yeeb nkab piles rau kev txhim khu kev qha, ruaj khov, thiab muaj txiaj ntsig zoo rau koj cov kev xav tau hauv av.
