321 stainless hlau yeeb nkab qhov chaw

2.321 stainless hlau yeeb nkab: nws yog tsuas yog siv los tsim cov pa roj carbon zoo steel, alloy structural steel thiab stainless kub-resistant steel seamless steel kav rau chav boiler kav nrog siab siab thiab saum toj no. Cov kav dej boiler no feem ntau ua haujlwm nyob rau hauv qhov kub thiab txias. Cov kav dej kuj tseem yuav raug oxidation thiab corrosion nyob rau hauv qhov kev txiav txim ntawm high-temperature flue gas thiab chav. Yog li ntawd, cov yeeb nkab steel yuav tsum muaj lub zog ntev ntev High oxidation tsis kam thiab zoo cov ntaub so ntswg stability, hydraulic prop raj.

3. 321 stainless hlau yeeb nkab txais qib steel: 304 321 316 317 310, thiab lwm yam

4.Alloy structural steel yeeb nkab steel qib: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, thiab lwm yam; 1Cr18Ni9 thiab 1cr18ni11nb siab boiler raj feem ntau siv nrog stainless thiab kub-resistant steel yuav tsum raug rau hydrostatic test, flaring thiab flattening xeem ib tug los ntawm ib tug ntxiv rau kom ntseeg tau cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom.

5.321 stainless hlau kav yog xa nyob rau hauv lub tshav kub kho mob. Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau microstructure, grain loj thiab decarburization txheej ntawm cov yeeb nkab steel tiav. Seamless steel yeeb nkab rau geological drilling thiab petroleum drilling tswj; Txhawm rau tshawb xyuas cov qauv pob zeb hauv av, dej hauv av, roj, cov khoom siv hluav taws xob thiab cov ntxhia pob zeb, cov khoom siv drilling yog siv los laum qhov dej.

Roj thiab roj exploitation yog inseparable ntawm drilling. Seamless steel yeeb nkab rau geological drilling tswj thiab roj drilling yog cov cuab yeej tseem ceeb rau kev drilling, feem ntau suav nrog cov tub ntxhais sab nrauv, cov tub ntxhais hauv cov yeeb nkab, casing, laum yeeb nkab, thiab lwm yam. , 1Cr5Mo alloy yeeb nkab yog siv.

6.Cov xwm txheej ua haujlwm yog qhov nyuaj heev. Lub laum yeeb nkab bears cov kev ntxhov siab los ntawm nro, compression, dabtsi yog khoov, torsion thiab unbalanced impact load, thiab tseem hnav los ntawm av nkos thiab pob zeb. Yog li ntawd, cov yeeb nkab yuav tsum muaj lub zog txaus, hardness, hnav tsis kam thiab cuam tshuam toughness. Cov yeeb nkab steel yog sawv cev los ntawm "DZ" (Geological Suav Pinyin prefix) ntxiv rau tus naj npawb ib los sawv cev rau cov hlau yield point, Cov qib steel feem ntau yog 45mnb thiab 50Mn ntawm dz45; 40Mn2 thiab 40mn2si ntawm dz50; 40mn2mo thiab 40mnvb ntawm dz55; 40mnmob ntawm DZ60 thiab 27mnmovb ntawm dz65. Cov yeeb nkab steel raug xa mus rau hauv cov cua sov kho.

Petroleum cracking yeeb nkab: seamless yeeb nkab rau cov yeeb nkab rau cov yeeb nkab, cov yeeb nkab kub exchanger thiab cov kav dej hauv cov roj av refinery. Nws feem ntau yog ua los ntawm cov pa roj carbon zoo (10, 20), hlau alloy (12CrMo, 15CrMo), cov hlau tsis muaj cua sov (12cr2mo, 15cr5mo) thiab stainless hlau (1Cr18Ni9, 1Cr18Ni9Ti).

7.Stainless hlau yeeb nkab: txhua yam ntawm stainless hlau kub-kuav los tiag thiab txias-kuav los tiag stainless hlau kav yog dav siv nyob rau hauv roj av thiab tshuaj siv cov kav dej thiab stainless hlau yam ntxwv qhov chaw rau ntau yam hom phiaj. Ntxiv nrog rau kev ua kom muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, tag nrho cov kav hlau steel siv los dais kua dej yuav tsum tsim nyog hauv kev sim hydrostatic. Ntau yam tshwj xeeb steel kav yuav tsum tau lav raws li cov txheej txheem teev tseg.

Welded steel yeeb nkab: tseem hu ua welded yeeb nkab, nws yog ua los ntawm steel phaj los yog steel sawb tom qab khoov thiab ces welding. Raws li daim ntawv weld, nws tau muab faib ua cov yeeb nkab ncaj welded thiab kauv welded yeeb nkab.

Raws li lub hom phiaj, nws muab faib ua welded yeeb nkab, galvanized welded yeeb nkab, oxygen tshuab welded yeeb nkab, hlau tes tsho, metric welded yeeb nkab, idler yeeb nkab, sib sib zog nqus twj tso kua mis yeeb nkab, 321 stainless hlau yeeb nkab, tsheb yeeb nkab, transformer yeeb nkab, hluav taws xob vuam. nyias-phab ntsa yeeb nkab, hluav taws xob vuam tshwj xeeb-zoo li tus yeeb nkab thiab kauv welded yeeb nkab.
