Carbon Steel Welded Steel Yeeb Nkab: Ib qho kev daws teeb meem, tsis yog cov yeeb nkab

Ib qho kev nkag siab txawv ntawm "pipe"

Cov neeg feem coob kho cov kav dej raws li cov neeg nqa khoom passive. Peb tsis ua.

Lub siab - zoo welded steel yeeb nkab yogib tug active kev tiv thaiv rau koj tag nrho cov system. Nws tsis yog ib qho pheej yig hloov rau seamless yeeb nkab, tab sis ib tug precision industrial tivthaiv ua los ntawm kub / txias dov coils, tsim thiab welded ntawmERW (High -Frequency Induction Vuam)los yogSAWH (kauv submerged Arc Vuam)kom ua tau zoo dua lub zog, toughness, roundness, thiab straightness.

Cov Txheej Txheem Tseem Ceeb

Minimized HAZ – Nyob ze -Base Metal Weld Properties

Tsawg cua sov input + ceev txias → HAZ dav Tsawg dua los yog sib npaug rau 1.5mm

Weld hardness Tsawg dua los yog sib npaug rau HV220, qhov sib txawv ntawm lub hauv paus hlau Tsawg dua lossis sib npaug li 10%

Tseem ceeb txo weld corrosion thiab cracking txaus ntshai

Smooth Internal Weld Bead (Low Fouling, Tsawg Drag)

Optional Internal Bead Control (IBC) → Internal weld reinforcement Tsawg dua los yog sib npaug rau 0.2mm

Dej tsis kam txo los ntawm 15% -20%

Zoo tagnrho rau zaub mov, tshuaj, dej demineralized, tshuaj zoo

Tag Nrho Traceability - Txhua Cov Yeeb Nkab muaj tus kheej

Independent cua sov tooj rau txhua kauj thiab cov yeeb nkab tiav

Weld taug qab code muaj

Txhawb API 5L, EN 10204 Hom 3.2 ntawv pov thawj

Engineered rau cov teeb meem tiag tiag

Teb teeb meem	Peb Kev daws
Thaum ntxov weld corrosion	Pickling + passivation ntawm weld cheeb tsam; ntsev tsuag test Ntau tshaj los yog sib npaug rau 500h
High rework tus nqi nyob rau hauv teb welding	Ua ntej-beveled xaus (V / Y / K hom) + kawg galvanized los tiv thaiv- xeb
Loj txoj kab uas hla, tsis sib xws phab ntsa thickness	CNC weld taug qab rau kauv kav; phab ntsa thickness sib txawv Tsawg dua los yog sib npaug rau ± 0.2mm
Tsawg-kub nkig tawg	Yeem -20℃/ -40℃Charpy V-notch impact test

Tshaj li Cov Qauv - Daim Ntawv Thov -Kev xaiv tsav

GB/T 3091 (tsawg-kua kua)
ASTM A53
API 5L (kab yeeb nkab)

Thiabkev cai engineering xaiv:

H₂S kev pab cuam → HIC/SSCC-cov qib resistant steel
Offshore / siab ntsev tsuag → sab hauv txheej + sab nraud 3PE / 3PP
Kev kub siab sab nraud (faus) → thickened phab ntsa + lub tshuab nqus tsev vacuum qhia

Cov ntawv thov ib txwm (Ntau dua li cov kav dej xwb)

Cov tsev lag luam– ntev -span ru tsev trusses, kem txhawb
Slurry thauj- hnav-cov pa roj carbon steel nrog siab-Cr puab txheej
Piling ua haujlwm- steel yeeb nkab pawg hauv cov av mos
Cov qauv ib ntus– ceev- sib dhos scaffolding, txhawb kab
Kub exchanger plhaub- qis- siab sab kauv welded plhaub

Kev sib piv tus nqi Lifecycle (DN200 × 6mm, 10-xyoo kev ua haujlwm)

Yam khoom	Welded steel yeeb nkab	Seamless Yeeb Nkab
Khoom siv	-25% rau -30%	Lub hauv paus
Installation ua haujlwm	20% tsawg dua pob qij txha (kev cai ntev)	Ntau cov pob qij txha
