Tam sim no, txawm hais tias tsis muaj ntau tus neeg siv cov kav dej stainless hlau, lawv tau ua raws li kev siv hluav taws xob vuam - ncaj seam welded kav. Kauv welded kav. Txoj cai-kaum yeeb nkab sib koom ua lag luam yog cais los ntawm phab ntsa tuab - tuab-walled seamless kav. Precision seamless steel kav muab faib los ntawm cov khoom siv: 304 stainless hlau dej kav; 304L stainless hlau kav dej; 316 stainless hlau kav dej; 316L stainless hlau kav dej; Cov txiaj ntsig Stainless hlau phaj yog ib hom khoom noj qab haus huv uas tuaj yeem muab tso rau hauv tib neeg lub cev, yog li xaiv cov kav hlau stainless yog qhov zoo tshaj plaws rau cov kav dej. Hauv kev ntsuas dej raus dej, txhua qhov ntsuas tau ua raws li cov cai tswj dej hauv tsev hauv kuv lub tebchaws. Sab hauv phab ntsa ntawm ferrule hom yeeb nkab sib txuas yog du, thiab nws tsis yooj yim rau kev tso nyiaj tom qab siv mus ntev. .Nws tsis yooj yim rau xim los ntawm cov kab mob pathogenic, thiab tsis tas yuav txhawj xeeb txog kev puas tsuaj ntawm cov dej, uas tuaj yeem zam cov dej qias neeg thib ob. Qhov zoo ntawm stainless hlau dej yeeb nkab raw khoom xaiv Tag nrho cov ntaub ntawv raw tau muab faib ua 304.304L.316.316L, uas yog raws li JIS4305 cov cai. Cov qib saum toj no muaj cov yam ntxwv ruaj khov nrog kev hnav tsis kam thiab qis thermal expansion coefficient.
Kev sib tw kom zoo dua ntawm cov kav dej stainless hlau yog tias lub sij hawm ntev nyias thiab siab ntom ntom chromium-nplua nuj oxide zaj duab xis rau ntawm daim hlau stainless steel phaj txhawb nqa cov kav dej stainless hlau kom muaj cov khoom zoo corrosion ntawm tag nrho cov dej zoo nrog rau cov dej muag. kev kho mob, txawm tias thaum paving. Nws muaj kev tiv thaiv corrosion zoo heev. Cov ntaub ntawv pov thawj corrosion ntawm cov ntaub ntawv qhia txog kev siv cov kav dej stainless hlau. Lub neej kev pab cuam mus txog 100 xyoo, thiab feem ntau ntawm cov customized lifespan ntawm welded yeeb nkab pob qij txha tsis xav tau kev saib xyuas, uas zam cov nqi thiab cov teeb meem tshwm sim ntawm pipeline disassembly, thiab cov kev siv tag nrho cov nqi yog tsawg. Qhov zoo ntawm cov kav dej stainless hlau yog qhov kub thiab txias tsis kam thiab siab siab. Txawm hais tias nws yog qhov kub thiab txias, nws tsis yooj yim los daws cov teeb meem, thiab cov khoom siv raw khoom ruaj khov heev. Lub zog compressive ntawm stainless hlau dej kav tshaj 530N / mm, thiab nws muaj cov khoom zoo ductility thiab plasticity.
