Cov yeeb nkab uas tsis tshua muaj kub yog dab tsi?
Cov yeeb nkab kub qis yog hais txog cov kav dej tshwj xeeb uas tsim los tiv thaiv thiab ua haujlwm zoo hauv ib puag ncig uas tsis muaj qhov kub thiab txias, feem ntau qis dua 0℃(32℃F). Cov kav dej no feem ntau siv rau hauv kev lag luam xws li roj thiab roj, petrochemicals, thiab tub yees, qhov twg cov dej yuav tsum tau thauj lossis khaws cia rau qhov kub thiab txias. Lawv tau tsim los ntawm cov khoom siv uas tuaj yeem tswj tau lawv cov khoom siv kho tshuab thiab kev ua haujlwm ruaj khov txawm tias nyob rau hauv qhov chaw txias heev, ua kom muaj kev nyab xeeb thiab kev thauj mus los ntawm cov kua dej. Tsis tas li ntawd, cov kav dej kub tsis tshua muaj hluav taws xob tiv thaiv kom tsis txhob muaj cua sov hloov mus rau qhov kub thiab txias ntawm cov dej xa mus.

Thaum siv qis-kub steel kav, koj yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no:

 

Kev xaiv thiab khaws cia cov khoom:
Thaum xaiv, xyuas kom tseeb tias koj nkag siab cov specifications, qhov ntev thiab cov qauv zoo ntawm cov khoom kom tau raws li koj cov kev xav tau tshwj xeeb. Kev khaws cia thiab kev thauj mus los ib puag ncig ntawm cov kav hlau yuav tsum qhuav thiab huv si kom tsis txhob muaj corrosion thiab puas.
Installation thiab kev sib txuas:
Thaum txhim kho qis -kub steel kav, txoj kev txhim kho kom raug yuav tsum tau ua raws li kom ntseeg tau tias lawv raug ntsia kom ruaj ntseg kom tsis txhob muaj teeb meem xws li xau. Thaum lub sij hawm kev teeb tsa, cov kev qhia tshwj xeeb thiab cov qauv tsim nyog yuav tsum tau ua kom ntseeg tau tias cov kav dej steel txuas ruaj khov thiab kaw. Kev ntxuav hauv cov raj xa dej yog qhov tseem ceeb heev kom tsis txhob muaj impurities ua rau kev puas tsuaj rau cov yeeb nkab steel.
Vuam thiab cua sov input:
Thaum vuam, cov txheej txheem vuam tsim nyog thiab cov khoom siv hluav taws xob yuav tsum raug xaiv kom tsis txhob muaj cov qauv ntxhib hauv cov hlau vuam thiab ze rau - seam cheeb tsam. Rau qis-kub steels, vuam kab ntau dhau zog tuaj yeem ua rau txo qis hauv kev sib koom ua ke, yog li qhov vuam tam sim no, arc voltage thiab vuam ceev yuav tsum tau tswj nruj me ntsis thaum lub vuam txheej txheem.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua:
Thaum siv qis-kub seamless steel kav, kev tshuaj xyuas tsis tu ncua, suav nrog kev ntsuas siab, ntsuas dej, thiab lwm yam, yuav tsum tau ua kom ntseeg tau tias kev ua haujlwm ruaj khov. Ua tib zoo saib xyuas kev siv cov kav dej steel, thiab nrog lawv nyob rau lub sijhawm yog tias muaj kev txawv txav tshwm sim. Nyob rau hauv ib qho chaw ntub dej, yuav tsum tau them nyiaj rau kev tiv thaiv - xeb txij nkawm ntawm cov kav dej steel, thiab kev tshuaj xyuas tsis tu ncua ntawm cov kav hlau steel yuav tsum tau ua. Yog tias muaj xeb, nws yuav tsum tau kho raws sijhawm.
Kev ntsuas rwb thaiv tsev:
Nyob rau hauv qhov chaw qis - qhov kub thiab txias, cov kav hlau muaj qhov ua rau muaj teeb meem xws li xau thiab frosting. Kev ntsuas rwb thaiv tsev rau cov kav dej yuav tsum tau ua kom muaj zog kom ruaj khov ntawm cov kav dej.

 

Siab -kub alloy steel kav yog hu ua chromium-molybdenum kav.
Cov kav hlau kub kub tau muab faib ua peb hom:
Kub kub carbon steel yeeb nkab
High kub alloy steel yeeb nkab
Kub kub stainless hlau yeeb nkab

Dab tsi yog qhov zoo ntawm kev siv cov kav dej seamless ntawm qhov kub thiab txias?
 

Kub kub kuj:Seamless kav rau kev siv kub tuaj yeem tiv taus qhov kub thiab txias siab yam tsis muaj deformation, tawg, lossis corrosion.

 

Corrosion kuj:Seamless kav rau qhov kub thiab txias siv tau zoo heev corrosion kuj thiab yog haum rau siv nyob rau hauv hnyav ib puag ncig.

 

Kev nyab xeeb:High -cov kav dej kub seamless yog txhim khu kev qha thiab muaj kev nyab xeeb, muab txoj kev nyab xeeb rau kev thauj mus los hauv dej hauv qhov kub thiab txias.

 

Ib qho yooj yim installation:Siab -kub seamless yeeb nkab yog ib qho yooj yim rau nruab thiab tuaj yeem ua ke tau yooj yim rau hauv cov kav dej uas twb muaj lawm, txo cov sij hawm poob thiab cov nqi tu.

 

Kub kub carbon steel yeeb nkab
ASTM A179, A192, A210 specifications npog carbon steel seamless yeeb nkab rau kev siv kub. Cov kav dej no yog siv rau hauv cov khoom siv hluav taws xob, cov condensers thiab cov ntaub ntawv kub siab yuav tsum ua raws li Specification A 530.
GB5310-2008 yog tsim rau kev tsim cov kav dej seamless rau chav boilers ntawm kev kub siab thiab saum toj no thiab seamless kav siv los ua cov kav dej.
ASTM A179 / A179M - 90a Standard Specification rau Seamless Cold Drawn Mild Steel Heat Exchanger thiab Condenser Tubes
ASTM A192 / A192M Txuj Kev Qhia Tshwj Xeeb rau Siab -Siab Seamless Carbon Steel Boiler Tubes
