High quality stainless hlau square tube
Stainless hlau square raj yog ib hom hollow ntev hlau. Vim tias seem yog square, nws hu ua square tube. Ntau cov kav dej siv los thauj cov kua dej, xws li roj, nkev, dej, roj, nkev, thiab lwm yam, ntxiv rau, thaum khoov thiab torsional lub zog zoo ib yam, qhov hnyav kuj yog lub teeb, yog li lawv kuj dav dav. siv nyob rau hauv kev tsim khoom ntawm mechanical qhov chaw thiab engineering qauv.
Kev faib tawm ntawm stainless hlau square yeeb nkab: square yeeb nkab yog muab faib ua seamless steel yeeb nkab thiab welded steel yeeb nkab (slotted yeeb nkab). Raws li cov duab seem, nws tuaj yeem muab faib ua cov kav dej square thiab square. Lub voj voog steel kav tau siv dav, tab sis kuj tseem muaj qee qhov tshwj xeeb-zoo li tus steel kav xws li semicircular, hexagonal, equilateral daim duab peb sab thiab octagonal.
Rau stainless hlau square yeeb nkab bearing kua siab, hydraulic xeem yuav tsum tau nqa tawm los xyuas nws cov siab tsis kam thiab zoo. Nws yog qhov tsim nyog yog tias tsis muaj qhov xau, ntub dej lossis nthuav dav raws li qhov ntsuas siab. Qee cov yeeb nkab steel kuj tseem yuav raug kuaj crimping, kuaj flaring, flattening test, thiab lwm yam raws li tus qauv lossis cov kev xav tau ntawm tus neeg thov.
Specification ntawm square tube: 5 * 5 ~ 150 * 150 hli thickness: 0.4 ~ 6.0 hli
Square tube khoom: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347h, 310S
Cov hlau tuaj yeem hnov mob nrog oxygen hauv qhov chaw los tsim cov oxide zaj duab xis ntawm qhov chaw. Cov hlau oxide tsim los ntawm cov pa roj carbon zoo tib yam yuav txuas ntxiv oxidize, nthuav cov corrosion thiab thaum kawg tsim qhov. Qhov no tuaj yeem siv cov xim lossis oxidation resistant hlau rau electroplating los tiv thaiv cov pa roj carbon steel, tab sis cov txheej txheem tiv thaiv no tsuas yog ib zaj duab xis nyias. Yog tias cov txheej tiv thaiv puas lawm, cov hlau hauv qab yuav pib xeb dua. Txawm hais tias cov yeeb nkab steel hlau tsis xeb yog cuam tshuam nrog cov ntsiab lus chromium hauv cov hlau. Thaum cov ntsiab lus chromium nyob rau hauv cov hlau nce mus txog 12%, ib txheej ntawm passivated thiab ntom chromium nplua nuj oxide yog tsim rau ntawm qhov chaw ntawm stainless hlau yeeb nkab nyob rau hauv cov cua los tiv thaiv nto thiab tiv thaiv reoxidation ntxiv. Cov oxide txheej no nyias nyias. Los ntawm nws, koj tuaj yeem pom lub ntuj ci ntawm cov hlau nto, uas ua rau cov hlau tsis muaj qhov tshwj xeeb nto. Yog tias cov yeeb yaj kiab chromium puas lawm, cov chromium hauv cov hlau thiab cov pa oxygen hauv cov cua yuav rov tsim cov yeeb yaj kiab passive mus txuas ntxiv ua lub luag haujlwm tiv thaiv. Hauv qee qhov chaw tshwj xeeb, cov hlau tsis muaj steel kuj yuav ua tsis tiav vim qee qhov kev xeb hauv zos, tab sis tsis zoo li cov hlau tsis zoo, cov hlau tsis xeb yuav tsis ua haujlwm vim tsis zoo corrosion, yog li qhov kev tiv thaiv corrosion tsis muaj nuj nqis rau cov kav hlau stainless.
