Nyob rau hauv lub realm ntawm ERW (hluav taws xob tiv thaiv welded) thiab swsaw (kauv subdgerging arc welded) kev sib raug zoo ntawm cov kab kev tsim khoom thiab kev ntseeg tau ntawm qhov kawg {}}} cov khoom. Peb kub - rolled steel kauj, Meticulously crafted tsim los ntawm cov txheej txheem tshwj xeeb ntawm ERW thiab SSAWW cov yeeb nkab mills. Los ntawm kev ua ntej sab nraud, ruaj khov kho cov qauv, peb txhawb cov qauv tsim kho kom tau lawv cov qauv tsim khoom, txo cov khoom lag luam uas ua tau raws li kev lag luam nruj tshaj plaws.
Txiav cov qhab nia sib xyaw nrog ERW & SSAW cov txheej txheem
Lub zog sib xws thiab ua tau zoo.
ERW cov yeeb nkab ntau lawm kev sib haum xeeb rau high- nrawm nrawm nrawm rau hauv ib lub cylindrical duab thiab welded raws cov seam ntev. Ib qho tsis sib haum xeeb nyob rau hauv cov khoom tuaj yeem ua rau vuam tsis xws luag lossis kab nres. Ntawm qhov tod tes, swsaw yeeb nkab raug cuam tshuam nrog cov steel kauj thiab vuam nws, xav tau kev tshwj xeeb tsis zoo ntawm cov qauv kev ncaj ncees ntawm kev kauv sab nrauv.
Peb kub - rolled steel chev yog engineered los daws cov kev xav tau ntawm cov kev xav tau ntawm ob qho tib si txheej txheem. Rau ERW Mills, nws qhov ntev thiab cov neeg kho twj ua ke lav tau cov kev sib tsoo thiab vuam ntawm cov kev kub ceev. Rau ssaw mills, cov coil's uniformity ua kom ntseeg tau tias kev sib tw ua kom muaj kev sib tw thiab kev ua haujlwm vuam ua tsis muaj lub zog thiab cov khoom zoo.
Superior Qhov Kev Ntsuas Xyuas
Flawless Vuam
D.Qhov Prectional yog lub hauv paus ntawm kev vam meej vuam hauv ob erw thiab ssaw yeeb nkab ntau lawm. Txawm tias kev sib txawv me me hauv thickness lossis dav yuav cuam tshuam cov vuam txheej txheem, ua rau cov pob qij txha tsis muaj zog, ua haujlwm tsis muaj zog, thiab cov khoom siv ntau ntxiv. Peb kub - rolled steel coils rau api 5}} ua rau kev tsim nyog rau kev lag luam, tshwj xeeb rau erw thiab ssaw mills.
Thickness kam zam: ± 0.1 hli
Peb kub - rolled steel kauj uas tau tuav ib qho Ultra 0.1mm hla tag nrho cov kauj-50% zaws dua li cov qauv API 5L ± 0.2 hli specification. Qhov no precision ua kom ntseeg tau:
Erw Siab - zaus vuam: Zoo meej ib txoj kev ntawm sawb npoo thaum v - kev sib sau. Thickness variations tshaj 0.1mm ua rau ntug kev tsis sib xws, destabilizing lub siab- zaus arc thiab nce siab ntsws nyob rau hauv welds txog 40%.
SSAW KAUV VUAM VUAM VUAM VUAM: Uniform siab faib ntawm helix overlap. Kev sib txawv ntawm 0.1mm ua rau nkag mus hauv subcutting arc wrds, qhov kev sib txawv ntawm cov qauv hauv siab hauv high- qhov kev thov siab.
Los ntawm kev tshem tawm cov khoob lossis sib tw ntawm kev sib koom ua ke vuam, qhov no ua rau muaj kev sib tw ua haujlwm ncaj qha
Qhov Dav Deev: ± 0.5 hli
Nrog txoj kev tiv thaiv nruj nruj ntawm ± 0.5 hli (ib nrab ntawm ± 1mm), peb cov coils ua kom muaj kev sib xyaw ua ke rau hauv erw thiab ssaw ua cov txheej txheem:
ERW Txoj Kev: Precise entry into cage forming rolls. Width deviations >0.5mm Misalign nyem yob, ua rau txias weld seams-} qhov tsis zoo nyob hauv cov roj thiab roj pipes.
SSAW Coiling: Zoo ib txwm muab kauv txoj hlua khi lub sijhawm coil txoj kev ua. Dav them nyiaj dhau 0.5 hli tsim "crescent gaps" hauv submerged arc vuam los ntawm 30}} txoj kab uas hla (ntau dua lossis sib npaug nrog ø2,000mmm) kav dej.
Cov Khoom Ruaj Ntseg Ruaj Ntseg
Ua ke muaj zog
Cov khoom siv me me ntawm cov hlau kauj, tshwj xeeb tshaj tawm lub zog muaj zog thiab lub luag haujlwm tseem ceeb hauv kev txiav txim siab lub zog ntawm welded pob qij txha hauv Erd thiab Ssaw Kav. Hloov pauv nyob rau hauv cov khoom no tuaj yeem ua rau tsis sib koom ua ke lub zog, cuam tshuam tag nrho cov kev ua tau zoo ntawm cov kav dej. Peb API 5L X60 Pipeline Hlau Coils Xa Kev Lag Luam Kev Lag Luam
Xij Zog Zog: ± 20MPA
Peb kub -}} rolled steel chev inegoes unegoes straws nruj thiab zoo tswj kom ntseeg tau cov khoom siv tau ruaj khov. Cov txiaj ntsig lub zog cov khoom pov thawj ultra- Tsis muaj ntau dua li API 5L tus qauv tsim nyog (± 40MPA). Qhov xwm txheej zoo sib xws:
ERW YEEB YEEB TAUS: Uniform deformation during roll forming. Yield strength fluctuations >30MPA ua rau ntug nthwv tawm suab nrov, nce kev ua kom zoo nkauj weld seam kev tsis zoo los ntawm 25%.
Ssaw Kauv Dabtsi Yog Khoov:Predictable material response to coiling stress. Variations >25Mpa ua rau muaj kev cia siab rau ntawm kev sib koom tes ntawm Helix sib koom tes, txo qis zog los ntawm 15% hauv cov roj roj kev kis tau.
Qhov tshwm sim: Tshem tawm cov kab nrib pleb / lub kua muag hauv siab {{0 zaus} zaus erw vuam weld piping hauv ssaw kav.
Tensile Lub Zog Kev Tswj: ± 30MPA
Lub zog tensile ntawm peb coils tswj kev tshwj xeeb tsis sib xws hauv ± 30MPA {1% stricter tshaj li zeb ntau dua li zeb txoj kev thev taus (± 50mPA). Qhov no lav:
ERW Longitudinal Seams: Uniform joint strength across entire pipe lengths. Tensile fluctuations >40MPA tsim cov pob hluav taws muaj zog hauv Weld Haz, nce hydrotest tsis tas yuav muaj kev pheej hmoo los ntawm 30%.
SSAW MAUV SAWV DAWS: Balanced stress distribution in submerged arc welds. Deviations >35MPA ua rau qhov tsis sib xws ctod toflaj, nrawm corrosion nyob rau hauv cov chaw muab kev pab cuam ib puag ncig.
Cov Khoom Siv Hlua Hlav Zoo Tshaj Rau Kev Txhim Kho Kev Txhim Kho
dshow tshuab co., ltd
Ib qho zoo -} tsim chev yog qhov tseem ceeb rau kev tswj cov yeeb nkab zoo hauv ERW thiab SSAWW FLICL MILLS. Cov tawv nqaij tsis zoo, xws li cov npoo winding lossis tsis muaj teeb meem, yuav ua teeb meem thaum tsis muaj zog, ua cov nqi zog, thiab cov nqi zog ua haujlwm, thiab nce nqi zog.
Peb kub {- rolled steel chev tshwj xeeb muaj coil zoo dua, nrog kev nruj thiab sib zog winding. Lub coil yog qhov txhab nyob rau hauv cov kev tswj hwm meej meej, kom txhua txheej yog nruj nreem ntim tawm tsam yav dhau los, tshem tawm cov ntu lossis khoob. Qhov kev ua cua ntub no tiv thaiv lub kauj ntawm unraving los yog kev hloov pauv thaum lub sijhawm ntim khoom thiab tsheb thauj mus los, ua kom tseem ceeb heev, ua kom cov uncoiling du thaum tsim khoom.
Lub kauj npoo yog tseem ua tib zoo txiav kom ncaj thiab txawm tias txo txoj kev pheej hmoo ntawm snags lossis jam raws li cov steel sawb yog pub rau cov kev ua tshuab. Qhov zoo tshaj plaws coil zoo minimizes qhov xav tau rau kev kho kom haum thaum lub sijhawm kev hloov khoom, txo lub sijhawm hloov pauv thiab tso cai rau cov kab ntau lawm kom tsis tu ncua ntev. Raws li qhov ua tau, cov chaw tsim khoom tuaj yeem ua tiav cov nqi tsim ntau dua, cov khoom siv qis dua, thiab txo cov nqi ua haujlwm.
