Khoom Taw Qhia

Cov pa roj carbon steel yog cov hlau uas muaj feem ntau ntawm cov pa roj carbon thiab hlau, feem ntau muaj cov ntsiab lus tsis tshua muaj alloying.Nws lub ntsiab feature yog tias nws muaj zog thiab hardness nyob rau hauv tej yam kev mob, thiab nws yog ib tug kuj yooj yim rau txheej txheem thiab tsis tshua muaj nqi.Cov pa roj carbon steel yog ib qho ntawm cov hlau ntau tshaj plaws thiab tau siv dav hauv ntau qhov chaw.

Cov yam ntxwv thiab kev faib tawm
1. Kev sib xyaw: Cov pa roj carbon steel feem ntau yog tsim los ntawm cov hlau thiab carbon, thiab cov ntsiab lus carbon feem ntau yog 0.1% thiab 2.0%.Ntxiv nrog rau cov pa roj carbon monoxide, nws kuj tseem yuav muaj me me ntawm silicon, manganese, phosphorus, sulfur thiab lwm yam khoom.
2. Lub zog: Lub zog ntawm cov pa roj carbon steel feem ntau yog siab dua thiab muaj cov khoom siv kho tshuab zoo dua.Qhov no ua rau carbon steel dav siv hauv kev lag luam xws li cov qauv, kev tsim kho thiab kev tsim khoom siv tshuab.
3. Hardness: Lub hardness ntawm carbon steel tuaj yeem tswj tau los ntawm kev kho cov ntsiab lus carbon, los ntawm softer low-carbon steel rau harder high-carbon steel.
4. Machinability: Txij li thaum carbon steel muaj tsawg alloying ntsiab, nws yog ib qho yooj yim rau txheej txheem thiab daim ntawv, thiab yuav siv tau los tsim cov khoom ntawm ntau yam complex duab.

Lub luj tshib yog ib qho kev sib txuas ntawm cov yeeb nkab siv los hloov cov kev taw qhia ntws ntawm cov yeeb nkab.Nws yog feem ntau yog tsim nyob rau hauv ib tug nkhaus uas txuas ob lub kav dej thiab ua rau lawv tig mus rau hauv cov lus qhia sib txawv.
Lub luj tshib yog cov yeeb nkab fittings hauv cov kav dej thiab tau siv dav hauv ntau yam kev lag luam thiab pej xeem.

1. Cov yam ntxwv zoo: Lub ntsiab feature ntawm lub luj tshib yog nws cov duab nkhaus.Lub luj tshib feem ntau yog ua los ntawm cov khoom siv hlau, xws li carbon steel, stainless hlau, hlau alloy, thiab lwm yam.
Nws muaj ntau lub kaum sab xis xaiv los ntawm, cov kaum sab xis yog 45 degrees, 90 degrees, 180 degrees thiab lwm yam.
Ob qhov kawg ntawm lub luj tshib yog txuas nrog cov yeeb nkab, ib qho kawg sib tw rau sab nraud ntawm cov yeeb nkab, thiab lwm qhov kawg yog qhov sib npaug ntawm cov yeeb nkab sab hauv.

2. Khoom siv: Lub luj tshib tuaj yeem ua los ntawm cov khoom sib txawv, feem ntau yog carbon steel thiab stainless hlau.
Carbon steel luj tshib yog tsim los ntawm carbon steel, uas yog ib tug hlau nrog ib tug siab carbon cov ntsiab lus thiab muaj zoo zog thiab machinability, yog li nws yog dav siv nyob rau hauv kev lag luam kev siv.Txawm li cas los xij, carbon steel lub luj tshib tsis haum rau qhov chaw muaj corrosive heev.Yog tias lawv yuav tsum tau siv rau hauv cov xov xwm corrosive, cov ntaub ntawv tsim nyog yuav tsum tau xaiv, xws li stainless hlau lossis hlau alloy.

3. Daim ntawv thov scenarios: Lub luj tshib yog dav siv nyob rau hauv ntau yam piping systems, xws li roj av, natural gas, tshuaj lom neeg kev lag luam, shipbuilding, dej mov, dej thiab dej thiab lwm yam kev lag luam.Lawv yog siv los hloov cov kav dej ntws, tso cai rau lawv mus ncig ib puag ncig cov teeb meem thiab ua kom haum cov txheej txheem sib txawv thiab qhov chaw nyob.

4. Hom: Lub luj tshib tuaj yeem muab faib ua ntau hom raws li txoj kev sib txuas, ntau hom muaj xws li lub luj tshib welded,threaded luj tshibthiabqhov (socket) welded luj tshib.Welded luj tshib yog txuas nrog cov yeeb nkab los ntawm vuam, threaded luj tshib yog txuas nrog threads, thiab lub qhov (socket) welded luj tshib yog txuas nrog lub qhov (socket welding).

5. Kev txhim kho: Thaum txhim kho lub luj tshib, nws yog ib qho tsim nyog los xyuas kom meej tias lub kaum sab xis ntawm lub bending.luj tshibua raws li cov kev xav tau ntawm cov kav dej.Xaiv lub kaum sab xis ntawm lub luj tshib yog ib qho tseem ceeb heev, vim tias lub kaum sab xis tsis tsim nyog yuav ua rau muaj kev txwv tsis pub muaj dej ntws los yog lwm yam tsis zoo.Thaum sib txuas, yuav tsum tau saib xyuas kom ntseeg tau tias qhov kev sib txuas yog nruj thiab tsim nyog ntsuas kev sib khi los xyuas kom meej qhov kev ntseeg tau thiab cov pov thawj ntawm cov yeeb nkab txuas.

Feem ntau, lub luj tshib yog cov yeeb nkab fittings hauv cov kav dej uas siv los hloov cov dej ntws ntawm cov kav dej.Lawv tau siv dav hauv kev lag luam thiab pej xeem kev lag luam, thiab lub luj tshib ntawm cov khoom sib txawv thiab cov ces kaum tuaj yeem xaiv raws li kev ua haujlwm tshwj xeeb thiab cov kev xav tau ntawm kev tshaj xov xwm.Thaum txhim kho thiab siv, cov qauv tsim thiab cov lus qhia tshwj xeeb yuav tsum tau ua raws li kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov kav dej.
