Cov lus piav qhia: 12Cr1MoV Seamless Alloy Steel Yeeb Nkab

2Cr1MoV yog Suav tus qauv (GB) chromium-molybdenum-vanadium alloy steel. Nws tau dav lees paub tias yog cov cua sov-cov hlau tsis muaj zog (feem ntau hu ua Chrome-Moly-Vanadium steel) tsim los rau siab - qhov kub thiab txias. Nws yog cov khoom ntawm kev xaiv rau kev siv tseem ceeb hauv kev tsim hluav taws xob thiab kev lag luam petrochemical vim nws cov oxidation zoo dua thiab muaj zog nkag.

Peb muab siab-zoo 12Cr1MoV seamless alloy steel kav, feem ntau tsim raws li GB/T 5310 (High-siab boiler standard). Cov khoom no muaj lub zog nkag siab zoo thiab oxidation tsis kam mus txog 585 degree. Nws yog cov khoom siv txheem rau superheaters thiab chav headers hauv fais fab nroj tsuag boilers. Peb tuaj yeem muab qhov ntev ntawm 10mm txog 800mm OD nrog phab ntsa thicknesses txog 100mm. Cov kav dej tau muab tso rau hauv qhov zoo li qub thiab tempered nrog daim ntawv pov thawj zeb tag nrho (MTC) raws li EN 10204 3.1

Manufacturing Standards & Specifications

Rau kev lag luam txawv teb chaws, nws yog ib qho tseem ceeb kom ua raws li Suav GB cov qauv nrog kev sib npaug thoob ntiaj teb lossis qhia meej tus qauv.

Thawj Suav Standards:

GB/T 5310: Seamless Steel Tubes thiab Yeeb Nkab rau Siab -Pressure Boiler. (Feem ntau rau qib no).

GB / T 8162: Seamless Steel Tubes rau Lub Hom Phiaj.

GB 3087: Seamless Steel Tubes rau Tsawg thiab Nruab Nrab Siab Boilers.

Qhov Loj:

Sab nrauv (OD): Feem ntau yog li ntawm 10mm txog 800mm (customizable mus txog 1422mm).

Phab ntsa Thickness (WT): Ntau yam ntawm 1.5mm txog 100mm.

Ntev: Feem ntau 6-12 meters, random lossis ruaj ntev.

Nco tseg:Cov khoom no feem ntau tsis muaj nyob rau hauv ASTM / ASME qib, tab sis nws feem ntau yog siv los ua lwm txoj hauv kev rau ASTM A213 T12 lossis A335 P12 (uas muaj cov tshuaj zoo sib xws tab sis sib txawv me ntsis ntawm cov khoom siv tshuab). Koj tuaj yeem muab qhov no rau cov neeg siv khoom tsim hluav taws xob raws li Suav cov qauv.

Kev kho cua sov & kev ua haujlwm:

Txhawm rau kom cov khoom ua tau zoo, kev ua kom raug yog yuav tsum tau:

Tus me nyuam qhov xwm txheej: Cov yeeb nkab feem ntau yog muab rau hauv Normalized + Tempered (N + T) mob (Quenching ntawm 970 degree, cua-txias; Tempering ntawm 700{5}}750 degree, cua txias).

Vuam: Zoo weldability, tab sis yuav tsum tau preheating (150{2}}200 degree). Kev kho cua sov tom qab vuam (PWHT) yog qhov yuav tsum tau ua kom txo qis kev ntxhov siab (720-760 degree)

Key Performance Advantages (Key Selling Points):

Thaum sib txuas lus nrog cov neeg siv khoom, hais txog cov txiaj ntsig tseem ceeb no:

-High -Temperature Strength & Creep Resistance:12Cr1MoV tswj cov qauv kev ruaj ntseg nyob rau hauv ntev - lub sij hawm siab - kub loads. Nws tiv taus "creep" (qhib deformation dhau sijhawm) ua haujlwm tau zoo txog qhov kub thiab txias ntawm 570℃txog 585 degree.

-Oxidation Resistance:Cov ntsiab lus Chromium tsim cov txheej txheem oxide tiv thaiv ntawm qhov chaw, tiv thaiv kev scaling thiab corrosion nyob rau hauv siab - qhov kub thiab txias.

-Stability:Nws muaj qhov zoo thermal stability, kom ntseeg tau qhov tseeb qhov tseeb txawm tias nyob rau hauv qhov hloov pauv thermal.

Chemical Composition (%)

Qhov kev ua tau zoo ntawm cov hlau no yog txhais los ntawm nws qhov tseeb ntawm cov tshuaj sib npaug. Qhov sib ntxiv ntawm Vanadium (V) txawv nws ntawm tus qauv Cr-Mo steels zoo li 15CrMo, muab siab dua - qhov kub thiab txias.

Element	Feem pua (%)	Muaj nuj nqi
Cov pa roj carbon (C)	0.08 – 0.15	Muab hardenability thiab lub zog.
Silicon (Si)	0.17 – 0.37	Deoxidizer; txhim kho siab -kub oxidation kuj.
Manganese (Mn)	0.40 – 0.70	Ua kom muaj zog thiab toughness.
Chromium (Cr)	0.90 – 1.20	Txhim kho corrosion kuj, oxidation kuj, thiab hardenability.
Molybdenum (hli)	0.25 – 0.35	Ua kom siab -kub creep zog thiab tiv thaiv temper embrittlement.
Vanadium (V)	0.15 – 0.30	Cov ntaub ntawv ruaj khov carbide; ho boosts siab -kub tensile zog thiab creep kuj.
Phosphorus (P)	Tsawg dua lossis sib npaug li 0.035	Impurity (tswj).
Sulfur (S)	Tsawg dua lossis sib npaug li 0.035	Impurity (tswj)
