1. Cov khoom yuav tsum tau ntawm steel tube Nyob rau hauv lubchaw kws tshuaj, cov khoom ntawm cov yeeb nkab steel yuav tsum tau ua raws li cov qauv nruj.
Corrosion tsis kam: Txij li cov txheej txheem tshuaj yuav raug rau ntau yam tshuaj, suav nrog acidic, alkaline lossis corrosive tshuaj cov khoom xyaw, steel tube yuav tsum muaj kev tiv thaiv corrosion zoo. Piv txwv li, qee cov hlau alloy steel raj lossis cov hlau sib xyaw ua ke yuav tsim nyog dua vim tias lawv zoo dua los tiv thaiv corrosion.
Purity: Cov khoom siv ntawm lub raj steel yuav tsum yog ntshiab kom tsis txhob muaj kab mob ntawm cov tshuaj. Cov qib impurity yuav tsum tau tswj nruj me ntsis kom ntseeg tau qhov zoo thiab kev nyab xeeb ntawm cov tshuaj. Yog hais tias carbon structural steel raj tuaj yeem ua tau raws li cov kev xav tau purity, lawv kuj tuaj yeem siv rau hauv qee yam ntawm cov chaw muag tshuaj, xws li qee qhov kev thauj mus los uas tsis muaj kev sib cuag nrog cov kws tshuaj. Txawm li cas los xij, kev tswj xyuas zoo thaum lub sijhawm tsim khoom yuav tsum tau ua kom tsis txhob muaj kev sib xyaw ntawm impurities.
Seamless steel tube:
Qhov zoo: Txij li seamless steel raj tsis muaj welds, tsis tshua muaj kev pheej hmoo ntawm kev xau thaum thauj cov kua dej, thiab cov phab ntsa sab hauv yog du, uas tuaj yeem txo cov dej tsis kam, uas yog ib qho tseem ceeb heev rau kev thauj cov dej hauv cov txheej txheem tshuaj, xws li kev thauj mus los. kua tshuaj. Hauv qee cov txheej txheem tshuaj uas yuav tsum tau ua kom huv huv heev, seamless steel raj tuaj yeem ua kom zoo dua cov tshuaj purity thiab tsis txhob kis cov tshuaj thaum lub sijhawm thauj mus los.
Daim ntawv thov scenario: Nws tuaj yeem siv los thauj cov kua tshuaj purity siab, dej distilled thiab qee cov khoom siv tshuaj uas yuav tsum tau ua kom huv si nruj. Piv txwv li, nyob rau hauv ib lub rooj cob qhia uas tsim cov tshuaj txhaj tshuaj, los ntawm kev npaj cov khoom siv raw mus rau cov khoom tiav tiav, yog tias cov raj steel siv rau kev thauj mus los, seamless steel raj yuav yog qhov kev xaiv zoo dua.
Welded steel yeeb nkab:
Qhov zoo: Kev ua tau zoo ntawm cov kav hlau welded yog qhov siab thiab tus nqi qis. Nws tuaj yeem siv rau hauv qee qhov chaw pabcuam tshuaj uas tsis muaj kev xav tau tshwj xeeb siab thiab muaj cov kev cai tshwj xeeb rau kev tiv thaiv corrosion thiab lwm yam khoom ntawm cov kav hlau.
Daim ntawv thov scenarios: Piv txwv li, hauv kev kho dej khib nyiab ntawm lub chaw tsim tshuaj, nws yog siv los thauj qee cov dej khib nyiab uas tau ua ntej kev kho mob thiab muaj me ntsis purity yuav tsum tau rau cov kav hlau steel, los yog siv los thauj cov cua hauv qee qhov cua tshuab.
3. Hlau rajqauv
Cov qauv kev tu cev: steel raj rau kev siv tshuaj yuav tsum ua raws li cov qauv kev nyiam huv. Sab hauv ntawm cov yeeb nkab steel yuav tsum du thiab yooj yim los ntxuav thiab tua kab mob kom tiv thaiv kev loj hlob ntawm cov kab mob thiab kab mob. Piv txwv li, lub puab nto roughness ntawm lub steel raj yuav tsum tau tswj nyob rau hauv ib tug tej yam kev mob los tiv thaiv cov residual kua los ntawm kev yug me nyuam cov kab mob thiab cuam tshuam rau qhov zoo ntawm cov tshuaj.
Cov qauv zoo: Lub zog, toughness thiab lwm yam khoom siv kho tshuab yuav tsum ua kom tau raws li qhov yuav tsum tau siv rau hauv cov txheej txheem tshuaj. Piv txwv li, nyob rau hauv qee qhov kev siv tshuaj ua kua hauv cov kav dej uas yuav tsum tau tiv taus qee qhov siab, cov kav dej steel yuav tsum muaj lub zog txaus los xyuas kom meej tias cov kav dej yuav tsis tawg, yog li zam kom tsis txhob muaj cov tshuaj to thiab kev tsim khoom. Piv txwv li, qee lub raj steel hauv GB / T8163-2008 (seaamless steel raj rau thauj cov kua) tus qauv tuaj yeem siv los ua cov kav dej xa dej hauv kev tsim tshuaj. Nws muaj cov kev cai meej meej ntawm qhov raug qhov tseeb, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab lwm yam ntawm cov raj steel los xyuas kom meej tias lawv muaj kev ntseeg siab hauv kev siv tshuaj.
