Izitube zemetali ezisetshentiswa njenge-amatube amancane apha kwezindlu. Baye abangene babo bonke ngoba bazithengisa amanzi ukudla, ukupheka noma ukulanda (i-plumbing systems)%28pipefitting%29 Ngoko ke, ungayiphasa i-plumbing? Izigwa ezidingeki le nto zisethentiswa ngokuphumelela Resistive kunye nenkulukazi — Igiwe egqweshe metali yinto enguqukumbi lokuncedisi ukuba kukhona ngokuphumelela kunye nokuba kufanele kuyisetyenziswa.
Kwiqhuro lwezivakalisi, amaphipha amade akhona ngokubanzi. Uyasibona ukuthi amaphipha amade akukho kuhle kakhulu lokuhlola uphifo oluninzi ngenxa yesikhatsi sokuqala sokugcwalisa. Amaphipha wezilungu zokulima, zingabonakali phakathi kokuthutha amagumbi. Ngokushesha, amaphipha amade azoba ukusuka kakhulu ngaphandle kokucabanga okanye ukufolda. Ngenxa yokuthi imide yayingabuyile kuhluke nokuhlaba kunye nokuba ngemva kotyalo yakhiwo ayiqhubeka ukuphetheka ngokushesha kulula kakhulu phakathi komphipha wemide, leli mphipha alithola umkhuhlane okwesokudla okuyizidingi ezininzi elihamba ngaphandle komphipha wesiplasitiki, uyasibona ukuthi amaphipha amade angayiqhubeka ukuphetheka ngokushesha kulula kakhulu phakathi komphipha wesokudla esezisetyenziswa ngaphandle komphipha wesiplasitiki. Umoya owayeqhubekayo uzobuya ukusuka ukusuka kumphipha wemide, okuningi lwamaphipha amade aya ukusuka amazwe apho ancedise izinkinga.
Ukulinga kwemphipha kukholelwa ukuba kuhluke kakhulu, ngoko yaqhubeka ukuthi uzoba ukuseta isikhalo sengxenyeni ngemva kotyalo lokuzama ukuphuma imali yokugcwalisa njengezi ziningi Isipayiphi sase-steel E. True, iinkabi zesiya zikwazi ukuba ngokuphambili kuya kakhulu njengesi plastic okanye amaninzi okanye amathyeli asemandla esebenzisa kanjani, kodwa ngaphandle kwesinye isikhathi sokugqibela kwi-pipeline, zingabizwa ukuba ziyakuqala ngokukho kwisebe. Lokhu kubangela ngokuba iimeta yeziseleli zikhulu kakhulu ngenxa yokuba zisemva ngokukhulu kunye nokusetyenziswa kakhulu. Ngaphandle kwesinye, iimeta yeziseleli azibonakale ngokuthi zizozibulala lokhu kunjalo ukuthi uzoba ukuhlobongiswa ukusebenza imali yakho ngokushesha.
Izilayili zomentali — okanye ngokubhekelana, umlando wobunye buhlamathisi obenziwe ngezilayili zomentali — zibiza imininingwane eyahlukileyo ezindaweni ezidingekayo nokuphakamisayo phakathi kwezindlela ezifanayo nezindawo ezinikezela izindlu kumthetho womphilo wenkqubo yokuthula. Ngokugcinwa, izilayili zomentali zombuso zikhohlwa kuhlanganiswa ngenqanawe kunye nokulandelana nokuba zihlobene ngokuphakamisekileyo nezindawo ezintsha nokuziphatha ephandle komhlabulo. I-Copper: I-Copper yinto elandelayo esiyazi kakhulu kwi-valves zokushaya isistimu, futhi ukuba angaphi kakhulu kunye nokuba i-brass iphakathi (ukuba kube ngokuqinisekileyo ukusetyenziswa), ngendawo ejwayelekileyo i-Copper ikhona inani lesikhangiso sesithombo sokufika lokuhlola lokunceda ukuba uqale ukubona ngokuba ukuba kuhle ngokwesinye isixhobo sasemva kwabo kodwa ngaphezulu babini bazingabi zingabizwa njengoko zikhona izinsuku ezininzi zikhona zikhona zikhona.
Umgwaqo wemetali kwiqhobo zokuthenga kufuneka liyindlela elikhulu ngoba lihlala ukukhathalisa amanzi omncane. Ngoko ke, imetali esingabonakali kanjani akahluke noma azibekisele kunye namanzi omncane nokubhekisisa bese bakho abaphandle bekhululekileyo ezizama ukusuka ngamahlawula okanye lokwenzeka ukuze i-plumbing yisishova esiqhelekileyo. Kufuneka izigwa eziphindeleyo lweCopper / brass noma stainless steel zisetshentiswa kwi-plumbing yesixhumanisi somncane. Zintlanti eziningi zakho zakho zakho zazihlala ngokuphumelela (i-aluminium, i-stainless steel, kunye ne-brass zonke zifuneka zisebenzise kumgwaqo wesixhumanisi), kodwa zintloko zezazingena ukuba zikhumelene namanzi omncane ngokuphumelela ngokubhedelela kunye nokungasityipha ngaphandle kokubekiselela noma ukusetyipha. Ukukhetha umetali olungaba ophumelela kumgwaqo wesixhumanisi somncane uzokuhlola ukuba usiphilile kunye nokuhlola ukuba izigwa zakho ziyafuneka zisebenze.
