Cylinders sib xyaw yog cov khoom siv sib xyaw uas tau ua los ntawm cov khoom siv li fiberglass thiab resin. Lawv muaj kev nyab xeeb thiab nyuaj siab, uas yog qhov tseem ceeb rau ntau yam kev lag luam. Ntau tus neeg yuav pom lawv rau hauv cov pab pawg gas lossis rau kev khoov cov lus uas muaj oxygen. Cov khoom siv composite cylinder yog qhov tseem ceeb thiab nyob rau hauv kev nyab xeeb, vim tias ntau yam kev lag luam tau paub txog qhov tseem ceeb ntawm cov cylinders no. Rau lub tsev lag luam li ACECCSE, uas ua cov cylinders no, no yog qhov txiaj ntsig zoo. Ntxiv rau qhov kev xav tau ntawm cov neeg siv tau nce, ACECCSE tau ready los xa cov khoom zoo rau kev tswj hwm cov neeg siv. Kev paub txog cov kev tseem ceeb thiab qhov nqi ntawm cov cylinders no yuav pab cov neeg siv wholesale kom tau kev xaum zoo.
Muaj ntau lub cim uas cov neeg siv tshuab rau qhov chaw siv tshuab yuav xav txog cov tshuab composite. Lub cim kawg, cov tshuab no yog qhov nyuaj heev. Nws tuaj yeem kuam cov pressure ntau thiab tsis tau puas. Qhov no yog qhov tseem ceeb rau kev nyab xeeb, tias yuav tsum kuam cov lus qhov chaw siv tshuab. Piv txwv li, cov tshuab composite tuaj yeem kuam cov lus li helium lossis hydrogen, uas xav tau cov tshuab nyuaj. Lub cim ob, cov tshuab composite yog qhov nyuaj tsis heev. Qhov no yog qhov tseem ceeb rau kev kuam cov tshuab, uas yuav pab cov chaw siv tshuab sau tau cov nqi kuam. Xav txog kev kuam cov tshuab nyuaj los ntawm cov tshuab metal compared to cov tshuab composite nyuaj tsis heev. Cov tshuab nyuaj tsis heev yog qhov yuav raug dua thiab yuav raug kuam dua. Lub cim peb, cov tshuab composite tsis tau puas los ntawm cov dej lossis cov lus qhov chaw siv tshuab. Tsis zoo li cov tshuab metal, cov tshuab composite tsis tau puas los ntawm cov dej lossis cov lus qhov chaw siv tshuab. Rau cov chaw siv tshuab uas xav tau kuam cov lus qhov chaw siv tshuab hauv qhov chaw siv tshuab lossis hauv qhov chaw siv tshuab txaus siab, qhov no yog qhov tseem ceeb. Lub cim plaub, cov tshuab composite muaj lub cim nyuaj dua. Nws tuaj yeem nyuaj ntau xyoo, uas yog qhov tseem ceeb rau kev kuam cov tshuab. Qhov no tuaj yeem pab sau tau cov nqi hauv qhov nyuaj. Thaum ntawd, cov tshuab composite tuaj yeem ua los ntawm ntau qhov ntsiab thiab ntau qhov loj rau kev siv tshuab. Yog tias cov chaw siv tshuab xav tau cov tshuab leej twg rau kev siv tshuab hauv lab lossis cov tshuab loj rau kev siv tshuab hauv chaw siv tshuab, muaj cov tshuab composite uas xav tau. Lub cim tsis, kev siv cov tshuab composite tuaj yeem pab pab cov chaw siv tshuab nyob hauv qhov chaw siv tshuab. Tias cov tshuab composite yog qhov tshiab thiab qhov tshiab, kev siv cov tshuab no tuaj yeem pab cov chaw siv tshuab nyob hauv qhov chaw siv tshuab thiab pab cov chaw siv tshuab nyob hauv qhov chaw siv tshuab. Rau kev saib ntau dua txog kev siv cov tshuab no, saib rau peb qhov chaw siv tshuab Siv rau tsev kawm .
