Ikirangantego cya kashe (kizwi kandi nka kaseti ya PTFE cyangwa kaseti ya plumber) ni firime polytetrafluoroethylene (PTFE) kugirango ikoreshwe mu gufunga insinga. Kaseti igurishwa igabanijwe kugeza mubugari bwihariye no gukomeretsa ku kantu, byoroshye guhuhuta kuzenguruka insinga. Bizwi kandi nubucuruzi rusange-izina rya Teflon kaseti; mugihe Teflon mubyukuri isa na PTFE, Chemours (abafite ibimenyetso byubucuruzi) basanga iyi mikoreshereze atariyo, cyane ko batagikora Teflon muburyo bwa kaseti. Soma kashe ya kaseti yerekana amavuta yemerera kwicara byimbitse, kandi bifasha gukumira insinga zo gufata mugihe zidacukuwe. Kaseti nayo ikora nkuzuza ibintu byuzuza kandi bisiga amavuta, bifasha gufunga ingingo bitagoye cyangwa bikagorana gukomera, ahubwo bikoroha gukomera.
Mubisanzwe kaseti yazengurutswe kumutwe wumuyoboro inshuro eshatu mbere yuko ihindurwa ahantu. Bikunze gukoreshwa mubucuruzi mubisabwa harimo sisitemu y'amazi akandamijwe, sisitemu yo gushyushya hagati, hamwe nibikoresho byo guhunika ikirere.
Ubwoko
Ikirangantego cya kashe isanzwe igurishwa mumashanyarazi mato.
Hariho amahame abiri yo muri Amerika yo kumenya ubuziranenge bwa kaseti iyo ari yo yose. MIL-T-27730A (ibisobanuro bya gisirikare bitagikoreshwa biracyakoreshwa cyane mu nganda muri Amerika) bisaba umubyimba muto wa milimetero 3,5 na PTFE ntoya ya 99% .Icyiciro cya kabiri, AA-58092, nicyiciro cyubucuruzi gikomeza u umubyimba usabwa wa MIL-T-27730A kandi wongeyeho ubucucike bwa 1,2 g / cm3.Ibipimo bifatika birashobora gutandukana hagati yinganda; kaseti ya gaze ya gazi (kumabwiriza ya gaze yo mubwongereza) irasabwa kuba muremure kuruta ayo kumazi. Nubwo PTFE ubwayo ikwiriye gukoreshwa hamwe na ogisijeni yumuvuduko ukabije, igipimo cya kaseti nacyo kigomba kumenyekana ko kitarimo amavuta.
Ikirangantego cya kashe ikoreshwa mugukoresha amazi ni cyera cyane, ariko kandi iraboneka mumabara atandukanye. Bikunze gukoreshwa mu guhuza imiyoboro y'amabara yanditseho amabara (Amerika, Kanada, Ositaraliya na Nouvelle-Zélande: umuhondo kuri gaze gasanzwe, icyatsi cya ogisijeni, n'ibindi). Aya mabara-kode yo gufunga kaseti yatangijwe na Bill Bentley wo muri Unasco Pty Ltd mu myaka ya za 70. Mu Bwongereza, kaseti ikoreshwa mu ibara ry'amabara, urugero nk'umuhondo wa gaze, icyatsi kibisi cy'amazi meza.
Cyera - ikoreshwa kumutwe wa NPT kugeza kuri 3/8
Umuhondo - ikoreshwa kumutwe wa NPT 1/2 santimetero kugeza kuri 2, akenshi yanditseho "kaseti"
Umutuku - ukoreshwa kumutwe wa NPT 1/2 santimetero kugeza kuri 2, umutekano kuri propane nibindi bicanwa bya hydrocarubone
Icyatsi - PTFE idafite amavuta ikoreshwa kumurongo wa ogisijeni na gaze zihariye zubuvuzi
Icyatsi - kirimo nikel, kurwanya gufata, kurwanya gazi no kurwanya ruswa, ikoreshwa mu miyoboro idafite umwanda
Umuringa - urimo granules z'umuringa kandi byemejwe nk'amavuta yo kwisiga ariko ntabwo ari kashe
Mu Burayi BSI isanzwe BS-7786: 2006 igaragaza amanota atandukanye hamwe nubuziranenge bwibipimo bya kode ya PTFE.
