Sichaza amaphuzu abalulekile phakathi kwezinto ezimbili (insimbi emnene noma insimbi engagqwali) ngezansi. Insimbi engagqwali ihlala isikhathi eside kakhulu ezimeni ezinosawoti futhi ingasetshenziswa embonini yokudla, kuyilapho insimbi ethambile inamandla futhi ingafaka ingcindezi eyengeziwe ekushayeleni izikelemu.

insimbi ethambile:
Insimbi ethambile, eyaziwa nangokuthi i-carbon steel, iwuhlobo lwensimbi oluvame kakhulu kuzo zonke izinhlelo zokusebenza, futhi izinsimbi zamapayipi nazo ziyahluka. Futhi ingelinye lamabanga abanzi ensimbi amboza inhlobonhlobo yezakhiwo zemishini. Lokhu kusho ukuthi ukuqonda nokucacisa ibanga elifanele kungaba nomthelela omkhulu ekusebenzeni komkhiqizo oqediwe. Isibonelo, ukucindezelwa kanye nezidingo zamashidi ensimbi akha amaphaneli omzimba wezimoto ahluke kakhulu kulawo wezinto zokufaka ipayipi. Eqinisweni, ukucaciswa kwe-hose clamp efanelekile akufani ngisho negobolondo namabhande.

Okunye okungalungile kwensimbi ethambile ukuthi inokumelana nokugqwala kwemvelo okuphansi kakhulu. Lokhu kunganqotshwa ngokusebenzisa i-coating, ngokuvamile i-zinc. Umehluko ezindleleni zokumboza nezindinganiso kusho ukuthi ukumelana nokugqwala kungaba indawo eyodwa lapho izinsimbi zamapayipi zihluka kakhulu. Izinga le-British Standard for hose clamps lidinga amahora angu-48 okumelana nokugqwala okubomvu okubonakalayo ekuhlolweni kokufuthwa ngosawoti okumaphakathi okungama-5%, futhi imikhiqizo eminingi yekite engamakiwe iyehluleka ukuhlangabezana nale mfuneko.

Insimbi engagqwali:
Insimbi engagqwali iyinkimbinkimbi kakhulu kunensimbi ethambile ngezindlela eziningi, ikakhulukazi uma kuziwa ezimbanjeni zamapayipi, njengoba abakhiqizi abaqhutshwa izindleko ngokuvamile basebenzisa inhlanganisela yamabanga wezinto ezihlukene ukuze banikeze umkhiqizo ngezindleko eziphansi zokukhiqiza nokusebenza okuncishisiwe.

Abakhiqizi abaningi be- hose clamp basebenzisa insimbi engagqwali ye-ferritic njengenye indlela yensimbi ethambile noma njengenye indlela ebiza kancane kune-austenitic stainless steel. Ngenxa yokuba khona kwe-chromium ku-alloy, izinsimbi ze-ferritic (ezisetshenziswa kumabanga we-W2 ne-W3, ochungechungeni lwe-400-grade) azidingi noma yikuphi ukucubungula okwengeziwe ukuze kuthuthukiswe ukumelana nokugqwala. Kodwa-ke, ukungabikho noma okuqukethwe okuphansi kwe-nickel yale nsimbi kusho ukuthi izakhiwo zayo zingaphansi ngezindlela eziningi kune-austenitic stainless steels.

Izinsimbi ezingenasici ze-Austenitic zinezinga eliphakeme kakhulu lokumelana nokugqwala kuzo zonke izinhlobo zokugqwala, okuhlanganisa nama-asidi, anebanga lokushisa elibanzi kakhulu lokusebenza, futhi awawona ama-magnetic. Ngokujwayelekile amamaki angama-304 nama-316 eziqeshana zensimbi engagqwali ayatholakala; zombili izinto zokwakha zamukelekile ukuthi zisetshenziswe olwandle kanye nokugunyazwa kwerejista kaLloyd, kuyilapho amamaki e-ferritic engakwazi. Lawa mabanga angasetshenziswa futhi embonini yokudla neziphuzo, lapho ama-asidi afana ne-acetic, citric, malic, lactic kanye ne-tartaric acid angase angavumeli ukusetshenziswa kwezinsimbi ze-ferritic.
