Custom Brass Washer

Kev tsim cov txheej txheem ntawm Kev Cai Brass Washer tuaj yeem muab faib ua ob txoj hauv kev: precision stamping lossis CNC tig nyob ntawm thickness thiab batch loj. Cov txheej txheem txoj kev ncaj qha cuam tshuam rau ntug zoo thiab sab hauv kev ntxhov siab faib. Raws li ASTM B103 tus qauv rau tooj dag phaj stamping qhov chaw, thaum lub thickness tsawg dua 1.5 hli, siab -kev ceev stamping tuaj yeem ua kom ntseeg tau tias qhov kev faib ua feem ntawm lub teeb ci nyob rau hauv tus ntoo khaub lig-section tsis tsawg dua 75%, thiab qhov siab burr yog tswj tsis pub dhau 0.05 hli. Thaum lub thickness ntau tshaj 3.0 hli, tig tshuab yuav tsum tau kom tsis txhob xuas nrig ntaus cov kab nrib pleb. Qhov saum npoo roughness ntawm txoj kev tig tuaj yeem ncav cuag Ra{11}} microns.

 

 

Nyob rau tib lub sijhawm, raws li ASTM E18 hardness test qhia tau hais tias cov ntug hardness ntawm cov khoom stamped tuaj yeem nce li ntawm 10% piv rau thaj tsam hauv nruab nrab vim kev ua haujlwm txias. Rockwell B nplai nce los ntawm thawj 70 degrees mus rau 77 degrees. Qhov hardness gradient no pab txhim kho kev sib tsoo tsis kam ntawm sab nrauv ntawm lub gasket. Txawm li cas los xij, yog tias tus neeg siv khoom xav tau lub xeev tag nrho cov mos mos rau riveting lossis flanging, kev kho mob ntawm 300 degrees Celsius yuav tsum tau tom qab molding kom tusyees poob lub hardness qis dua 65 degrees, yog li ua tau raws li cov yas deformation peev xwm ntawm lub gasket yuav tsum tau los ntawm cov txheej txheem sib txawv.

 

 

Hauv kev ua haujlwm tshwj xeeb xws li qhov qis- qhov kub thiab txias los yog tawg- qhov chaw pov thawj, cov khoom siv tooj dag tau txais kev pom zoo rau lawv cov khoom uas tsis yog -tshuaj lom thiab muaj kev cuam tshuam ruaj khov. Raws li ASTM E23 Charpy impact test method, qhov cuam tshuam lub zog nqus ntawm tooj dag C26000 tseem tuaj yeem ncav cuag ntau dua 80 joules ntawm rho tawm 40 degrees Celsius, thaum cov pa roj carbon zoo tib yam feem ntau poob qis dua 40 joules ntawm tib qhov kub. Qhov qis- qhov kub thiab txias no ua rau cov tshuab ntxhua khaub ncaws uas haum rau kev sib txuas ntawm cov kav dej liquefied natural gas pipeline flanges lossis cov khoom siv cua hauv cov chaw txias. Nyob rau tib lub sijhawm, raws li ISO 80079-36 tawg-cov ntaub ntawv pov thawj qhia tsis yog{16}} cov khoom siv hluav taws xob. Brass yog cov khoom siv hluav taws xob tsawg.

 

 

Lub gasket customized yuav tsis tsim igniting sparks thaum hammered los yog rubbed. Nws yog tsim rau siv nyob rau hauv flammable thiab tawg qhov chaw xws li petrochemical kev lag luam. Nws cov thickness customized thiab sab hauv thiab sab nraud tuaj yeem hloov kho raws li Kev tawg - pov thawj sib koom ua ke deg clearance yuav tsum muaj qhov sib txuam. For example, the inner diameter tolerance can be tightened to plus or minus 0.005 mm to ensure a tight fit with the journal, thereby avoiding the penetration of flammable gas along the thread gap, which not only meets safety regulations but also extends the time window for regular maintenance.

 

 

 

 

 

 

 

Tau txais cov duab kos los ntawm cov neeg siv khoom lossis tsim cov duab kos raws li lawv cov qauv lossis cov qauv tshwj xeeb.

Cov duab kos, cov khoom siv raw, kev kho deg, thiab lwm yam ntsiab lus tau lees paub los ntawm ob tog.

 

 

 

 

Muab cov lus tsocai, xyuas kom meej tias qhov kev txiav txim kom muaj nuj nqis yog qhov tseeb, thiab suav nrog tag nrho cov ntsiab lus tseem ceeb,

xws li cov nqe lus ntawm kev them nyiaj, cov nqe lus ntawm kev lag luam, hom ntim, thiab lwm yam.

 

 

 

Ua raws li cov duab kos thiab cov qauv raws nraim thaum tsim cov khoom.

Nws tau ua tib zoo ntim thiab xa mus rau cov neeg siv khoom tom qab kev tshuaj xyuas zaum kawg.
