Ezweni elihlala lishintsha lokwakha nobunjiniyela, ukuthola izinto eziqinile nezihlala isikhathi eside kubalulekile. Phakathi kwezinto ezintsha eziye zavela eminyakeni yamuva, amapayipi ane-polyurethane-lined athole ukunakwa okukhulu ngekhono lawo lokuthuthukisa ukuqina kwamapayipi esakhiwo sesigaba esingenalutho. Lesi sihloko sihlola ukuthi ukuhlanganiswa kwe-polyurethane linings kungashintsha kanjani lezi zingxenye zesakhiwo, kuzenze zibe namandla futhi ziphumelele ekusetshenzisweni okuhlukahlukene.
Amapayipi esakhiwo sesigaba esingenalutho asetshenziswa kakhulu emikhakheni yokwakha, ingqalasizinda kanye nezimboni ngenxa yokuma kwe-tubular kanye nokuqina kwezindonga ezifanayo. Zenzelwe ukusabalalisa umthwalo ngendlela efanele futhi zilungele izakhiwo ezisekelayo njengamabhuloho, izakhiwo kanye nezikafula. Kodwa-ke, enye yezinselelo la mapayipi abhekene nayo ukuthi angakwazi ukugqwala, ukuguga kanye nokuhuzuka, ikakhulukazi ezindaweni ezinzima. Yilapho kungena khona izingqimba ze-polyurethane
I-polyurethane iyi-polymer eguquguqukayo eyaziwa ngezinto zayo ezinhle kakhulu zemishini, okuhlanganisa amandla aqinile, ukuguquguquka, nokumelana namakhemikhali kanye nezici zemvelo. Lapho i-polyurethane isetshenziswa njengolwelwesi lwamapayipi esakhiwo sesigaba esingenalutho, idala umgoqo ovikelayo owandisa kakhulu ukuqina kwepayipi. Le lining ayivimbeli nje kuphela ukugqwala okubangelwa umswakama kanye namakhemikhali, kodwa futhi kunciphisa ukugqoka kusuka kuma-abrasives, ukwandisa impilo yesevisi yepayipi.
Enye yezinzuzo ezibaluleke kakhulu zeipayipi elifakwe nge-polyurethaneamandla ayo okumelana nezimo ezimbi kakhulu. Ezimbonini ezifana nezimayini, uwoyela negesi, nokuphathwa kwamanzi angcolile, amapayipi avame ukuchayeka ezintweni ezigqwalile kanye nezinto ezihuquzelayo. I-polyurethane lining isebenza njengesithiyo, ivikela insimbi engaphansi ekuwohlokeni futhi iqinisekise ukuthi ubuqotho besakhiwo sepayipi buhlala bunjalo. Lokhu kuqina kusho izindleko eziphansi zokunakekela kanye nesikhathi esincane sokuphumula, okwenza ipayipi elifakwe i-polyurethane libe yisixazululo esingabizi kakhulu emabhizinisini.
Ukwengeza, izakhiwo ezingasindi ze-polyurethane zenza ipayipi lesakhiwo sesigaba esingenalutho kube lula ukuphatha nokufaka. Izinto zendabuko zingaba zikhulu futhi kube nzima ukusebenza ngazo, okuholela ekwenyukeni kwezindleko zabasebenzi kanye namashejuli amaphrojekthi anwetshiwe. Ngokuphambene, ipayipi eline-polyurethane-lined kulula ukuthutha nokufaka, ukuhlehlisa inqubo yokwakha nokuthuthukisa ukusebenza kahle kwephrojekthi jikelele.
Esinye isici esihle samapayipi afakwe i-polyurethane ukuguquguquka kwawo. Angenziwa ngokwezifiso abe nezidingo ezithile, okuhlanganisa ukujiya okuhlukile kolwelwesi, amamaki ahlukene e-polyurethane, nosayizi wamashubhu angenalutho ngokwezifiso. Lokhu kuvumelana nezimo kubenza bafanelekele uhla olubanzi lwezicelo, kusukela ekwakhiweni kwezindawo zokuhlala kuya kumaphrojekthi amakhulu ezimboni.
Ngaphandle kwezinzuzo ezingokoqobo, amapayipi ane-polyurethane-lined nawo afaka isandla ekuthuthukisweni okusimeme. Ngokwandisa impilo yesevisi yamapayipi esakhiwo kanye nokunciphisa isidingo sokushintshwa njalo, lezi zindlela ezintsha zisiza ukunciphisa ukumosha nokusetshenziswa kwezinsiza. Ukwengeza, izinqubo zokukhiqiza ezonga amandla ezihambisana ne-polyurethanes zisiza ukunciphisa izinyathelo zekhabhoni, ezihambisana nokugcizelela okukhulayo kwemikhuba yokwakha esimeme.
Kafushane, ukuhlanganiswa kwe-polyurethane linings kumapayipi esakhiwo sesigaba esingenalutho kubonisa intuthuko enkulu kubuchwepheshe bezinto. Ngokwandisa ukuqina nokunikeza isivikelo ekugqwaleni nasekuhuzukeni, amapayipi anemigqa ye-polyurethane ashintsha indawo yokwakha nobunjiniyela. Njengoba izimboni ziqhubeka nokufuna izixazululo ezithuthukisa ukusebenza kuyilapho zinciphisa izindleko, ukwamukelwa kwamapayipi anemigqa ye-polyurethane cishe kuzokhula, kuvule indlela yengqalasizinda eqinile nesebenza kahle.
