ʻO kaKiwikā o ka pepeke i hoʻopaʻa ʻia ʻo PTFEhe kiwikā ʻoihana hapaha-huli me kahi uhi piha o loko o Polytetrafluoroethylene — i ʻike nui ʻia ʻo Teflon — e hoʻokaʻawale loa ana i nā mea hana mai ke kino kiwikā metala. Hāʻawi kēia uhi i ke kūpaʻa maikaʻi loa i ka pala no nā kemika huhū, nā wai maʻemaʻe kiʻekiʻe, a me nā mahana koʻikoʻi, e lilo ia i koho makemake ʻia no nā ʻoihana koi a me nā wahi hana paʻakikī i ka wela.

Loaʻa nā liner PTFE a me PFA (Perfluoroalkoxy). ʻOiai ʻo PTFE e hāʻawi ana i ke kūpaʻa kemika ākea ākea, makemake pinepine ʻia ka PFA no nā noi vacuum kiʻekiʻe a i ʻole nā ​​​​​​noi i hoʻokaumaha ʻia ma muli o kona kūpaʻa kiʻekiʻe a me ka maʻalahi ma lalo o ke kaumaha mechanical.

ʻO kahoʻolālā kino māheleʻae i ka liner a me nā ʻāpana kūloko e komo a hoʻololi ʻia me ka ʻole o ka wehe ʻana i ka valve mai ka pipeline, e hōʻemi nui ana i ka downtime mālama a me ka uku holoʻokoʻa o ka nona.

A kiwikā i hoʻopaʻa piha ʻiauhi i nā ʻili pulu āpau - ke kino a me ka disc - e hāʻawi ana i ka palekana kiʻekiʻe loa i nā media corrosive loa. Akiwikā i hoʻopaʻa hapa ʻiaHoʻopili wale ʻo PTFE i ka noho, e hāʻawi ana i kahi hopena kūpono no nā wahi ʻino ʻole. Loaʻa nā hoʻonohonoho ʻelua ma ke noi.

Loaʻa i ʻekolu mau kaila kino e kūpono i nā hoʻonohonoho paipu like ʻole:ʻano wafer, ʻano ʻūmiʻi, a meʻano pālua flanged.
