Ntau yam khoom siv los ua cov kav dej corrugated. Nws yuav tsum muaj cov yas zoo thiab vuam kev ua tau zoo. Cov kav dej me me feem ntau yog ua los ntawm cov kav dej seamless, tab sis txoj kab uas hla me me stainless hlau corrugated kav dej yog tsim los ntawm vuam thiab polishing, uas yuav tsum tau softness thiab yooj. Cov yeeb nkab corrugated nrog ib txoj kab uas hla ntau tshaj 25mm tuaj yeem tsim rau hauv cov yeeb nkab corrugated los ntawm longitudinal seam vuam tom qab tsim ib daim ntawv los yog sawb.
Kev txiav txim siab ntxiv ntawm cov ntaub ntawv Cov khoom siv los tsim cov yeeb nkab corrugated, txawm hais tias nws yog cov yeeb nkab, ib txoj hlua, los yog phaj, txiav txim siab qhov tuab ntawm cov khoom siv raws li qhov yuav tsum tau ua ntawm cov yeeb nkab corrugated. Thaum rigidity tsis yog qhov tseem ceeb ntawm kev ua tau zoo, phab ntsa thickness kam rau ua yog +/-10% ntawm cov thickness. Thaum qhov yuav tsum tau rigidity siab dua, phab ntsa thickness kam rau ua yog +/-5% ntawm lub thickness. Cov nplej loj ntawm cov khoom siv corrugated ua ntej tsim yuav tsum tsawg dua 35 um, thiab qhov tsis sib xws ntawm cov nplej yuav tsum tsis txhob siab dua qib 2.
Cov ntaub ntawv siv los ua cov hauv qab feem ntau suav nrog stainless hlau, tin bronze thiab beryllium bronze.
Austenitic stainless hlau
Austenitic stainless hlau (1Cr18Ni9Ti, OCr18Ni9, 00Cr17Ni14Mo2, thiab lwm yam) muaj cov khoom siv zoo thiab corrosion kuj. Bellows ua nrog nws feem ntau yog siv los ua kev sib cais tawm lossis cov khoom sib khi.
Tin tooj
Tin bronze (QSn6.5-0.1, QSn6.5-0.4) muaj qee qhov kev hloov pauv, kev ua haujlwm zoo, tsis tshua muaj hysteresis, siab qaug zog, zoo corrosion kuj, thiab dav siv hauv meters.
Beryllium tooj liab
Beryllium bronze (QBe2) muaj zoo manufacturability, siab elasticity thiab plasticity, tsis tshua muaj hysteresis, zoo corrosion kuj, siab qaug zog, thiab tsis tshua muaj elastic kub coefficient. Bellows ua nrog nws feem ntau yog siv rau lub sijhawm xav tau siab.
tooj dag
Brass (H80) muaj cov yas zoo thiab cov txheej txheem ua tau zoo, tab sis nws muaj qhov tsis zoo elasticity thiab loj hysteresis. Lub tshuab nqus tsev ua los ntawm nws feem ntau siv nrog cov springs thiab feem ntau yog siv rau lub sijhawm uas yuav tsum tsis muaj siab.
Ntxiv rau cov khoom siv uas tau hais los saum toj no, muaj cov khoom siv tsis tu ncua elastic Ni36CrTiAl (3J1), kub-kub alloy Inconel 718, thiab lwm yam.
Kev tshuaj xyuas thiab kev lees txais cov ntaub ntawv yuav tsum tau ua raws li cov qauv tsim nyog. Cov ntaub ntawv nkag mus rau hauv lub Hoobkas yuav tsum muaj daim ntawv pov thawj zoo, thiab kev siv cov ntaub ntawv yuav tsum raug thiab traceable.
