Sichaza amaphuzu abalulekile phakathi kwezinto ezimbili (insimbi ethambile noma insimbi engagqwali) ngezansi. Insimbi engagqwali ihlala isikhathi eside ezimweni ezinosawoti futhi ingasetshenziswa embonini yokudla, kuyilapho insimbi ethambile inamandla futhi ingabeka ingcindezi eyengeziwe ekuqhutshweni kwezinambuzane.

insimbi ethambile:
Insimbi ethambile, eyaziwa nangokuthi insimbi yekhabhoni, iyindlela evame kakhulu yensimbi kuzo zonke izinhlelo zokusebenza, futhi ama-hose clamp awahlukile. Futhi ingenye yezinhlobo zensimbi ezibanzi kakhulu ezimboza izinhlobo eziningi zezakhiwo zemishini. Lokhu kusho ukuthi ukuqonda nokucacisa izinga elifanele kungaba nomthelela omkhulu ekusebenzeni komkhiqizo oqediwe. Isibonelo, ukucindezeleka nezidingo zamashidi ensimbi akha amaphaneli omzimba wezimoto kuhluke kakhulu kulokho kwezinto zokufaka ipayipi. Eqinisweni, ukucaciswa kwezinto ze-hose clamp ezifanele akufani ngisho negobolondo nezintambo.

Ububi obunye bensimbi ethambile ukuthi inokumelana nokugqwala kwemvelo okuphansi kakhulu. Lokhu kunganqotshwa ngokusebenzisa isembozo, ngokuvamile i-zinc. Umehluko ezindleleni zokumboza kanye nezindinganiso usho ukuthi ukumelana nokugqwala kungaba yindawo eyodwa lapho ama-hose clamps ehluka kakhulu. I-British Standard yama-hose clamps idinga amahora angu-48 okumelana nokugqwala okubomvu okubonakalayo ekuhlolweni kwe-5% salt spray, futhi imikhiqizo eminingi yama-kite engaphawuliwe ayihlangabezani nale mfuneko.

Insimbi engagqwali:
Insimbi engagqwali iyinkimbinkimbi kakhulu kunensimbi ethambile ngezindlela eziningi, ikakhulukazi uma kukhulunywa ngama-hose clamps, njengoba abakhiqizi abasebenzisa izindleko bevame ukusebenzisa ingxube yezinhlobo ezahlukene zezinto zokwakha ukuze banikeze umkhiqizo izindleko zokukhiqiza eziphansi kanye nokusebenza okuncishisiwe.

Abakhiqizi abaningi be-hose clamp basebenzisa insimbi engagqwali ye-ferritic esikhundleni sensimbi ethambile noma njengendlela engabizi kakhulu esikhundleni sensimbi engagqwali ye-austenitic. Ngenxa yokuba khona kwe-chromium ku-alloy, izinsimbi ze-ferritic (ezisetshenziswa kuma-W2 nama-W3 grade, ochungechungeni lwe-400-grade) azidingi noma yikuphi ukucutshungulwa okwengeziwe ukuze kuthuthukiswe ukumelana nokugqwala. Kodwa-ke, ukungabikho noma okuqukethwe okuphansi kwe-nickel kwale nsimbi kusho ukuthi izakhiwo zayo ziphansi ngezindlela eziningi kunezinsimbi ezingagqwali ze-austenitic.

Izinsimbi ezingagqwali zase-Austenitic zinezinga eliphakeme kakhulu lokumelana nokugqwala kuzo zonke izinhlobo zokugqwala, kufaka phakathi ama-acid, zinezinga lokushisa elibanzi kakhulu lokusebenza, futhi azinawo amandla kazibuthe. Ngokuvamile amagreyidi angu-304 no-316 ezinsimbi ezingagqwali ayatholakala; zombili izinto zamukelekile ukusetshenziswa olwandle kanye nokuvunyelwa kwe-Lloyd's Register, kuyilapho amagreyidi e-ferritic engakwazi. Lawa magreyidi angasetshenziswa futhi embonini yokudla neziphuzo, lapho ama-acid anjenge-acetic, citric, malic, lactic kanye ne-tartaric acid engase angavumeli ukusetshenziswa kwezinsimbi ze-ferritic.
