Njengoba abantu benaka kakhulu ukuvikelwa kwemvelo kanye nentuthuko eqhubekayo, ukusetshenziswa kwamapayipi ezimbonini nasezimbonini ezihlukahlukene sekujwayelekile. Nokho, amapayipi avame ukuchayeka ezindaweni ezinokhahlo, njengezinga lokushisa eliphezulu, umfutho ophezulu, kanye nemithombo yezindaba egqwalayo, okubangela umonakalo omkhulu kuzo, okuholela ezindlekweni zokunakekela eziphakeme futhi, kwezinye izimo, izingozi noma izinhlekelele zemvelo.Ukuze unqobe lezi zinselele, amapayipi angahlanganiswa nezingubo zokuzivikela ezifana3LPE ezinezingqimbakanye nezingubo ze-FBE zokwandisa ukumelana kwazo nokugqwala futhi kuthuthukiswe ukuqina kwazo.
I-3LPE, okungukuthi, i-polyethylene enezingqimba ezintathu, iyisistimu yokuhlanganisa enezendlalelo eziningi ehlanganisa ungqimba oluyisisekelo lwe-epoxy (FBE) oluhlanganisiwe, ungqimba olunamathelayo kanye nongqimba lwe-polyethylene topcoat.Uhlelo lokumboza lunokumelana nokugqwala okuhle kakhulu, amandla emishini kanye nokumelana nomthelela, okwenza lusetshenziswe kabanzi kuamapayipi kawoyela negesi,amapayipi amanzi nezinye izimboni lapho amapayipi echayeka ezindaweni ezigqwalile.
I-FBE coating, ngakolunye uhlangothi, iwuhlelo lwejazi elilodwa elihlanganisa i-thermosetting epoxy powder coating esetshenziswa ebusweni bepayipi.Uhlelo lokumboza lunokunamathela okuhle kakhulu, ukuhuzuka okuphezulu kanye nokumelana nomthelela kanye nokuphikiswa okuhle kwamakhemikhali, okuyenza ifanelekele ukuvikelwa kwamapayipi ezimbonini ezihlukahlukene ezifana nowoyela negesi, amanzi kanye nezokuthutha.
Kokubili ukunamathela kwe-3LPE kanye ne-FBE kusetshenziswa kakhulu kubunjiniyela bamapayipi ngenxa yezindawo zabo ezinhle kakhulu zokuvikela.Kodwa-ke, ububanzi bokusebenzisa kwabo kuyahlukahluka kuye ngesimo esithile ipayipi elidinga ukusisingatha.
Emapayipini kawoyela negesi, ukunamathela kwe-3LPE kuyathandwa ngoba kungamelana nesenzo sokugqwala sikawoyela negesi, kanye nomthelela nokungqubuzana kwenhlabathi ezungezile.Ngaphezu kwalokho, izimbotshana ze-3LPE nazo zingamelana nokuhlukaniswa kwe-cathodic, okuwukuhlukaniswa kwezingubo ezivela ezindaweni zensimbi ngenxa yokusabela kwe-electrochemical.Lokhu kubaluleke kakhulu kumapayipi avikelekile ekugqwaleni.
In amapayipi amanzi, Ukufakwa kwe-FBE kuyisinqumo sokuqala ngoba kungavimbela ngokuphumelelayo ukwakheka kwe-biofilm nokukhula kwamabhaktheriya, okungangcolisa ikhwalithi yamanzi.I-FBE coating ibuye ifanele amapayipi adlulisa imidiya evuthayo, njengesihlabathi, amatshe noma udaka, ngenxa yokumelana kwayo okuhle kakhulu nokugqoka.
Epayipini lezokuthutha, i-3LPE coating noma i-FBE coating ingasetshenziswa ngokuya ngesimo esithile sokuthutha.Uma ipayipi lichayeke endaweni egqwalayo, njengendawo ezungezile yasolwandle, ukumbozwa kwe-3LPE kuyathandwa ngoba kumelana nesenzo sokugqwala samanzi olwandle nezinto eziphilayo zasolwandle.Uma ipayipi sivezwa kumithombo ye-abrasive efana namaminerali noma ama-ores, i-FBE coating ikhethwa njengoba inganikeza ukumelana okungcono kokugqoka kunokunamathela kwe-3LPE.
Ukufingqa, ububanzi bokusetshenziswa kwe-3LPE coating kanye ne-FBE coating iyahlukahluka ngokuya ngemibandela ethileubunjiniyela bepayipi.Lezi zinhlelo ezimbili zokumboza zinezinzuzo zazo kanye nokubi.Ukukhethwa kwesistimu yokumboza kufanele kucubungule ngokujulile izici ezihlukahlukene ezifana nesimo sendawo ephakathi nendawo, izinga lokushisa nokucindezela kwepayipi, nendawo ezungezile.Ngokuthuthuka okuqhubekayo kobuchwepheshe bepayipi, sikholelwa ukuthi kuzoba nezinhlelo zokumboza ezintsha nezisebenza kahle ukuze kuhlangatshezwane nezidingo ezikhulayo zokuvikela nokuphepha kwamapayipi.
Sinefekthri elwa nokugqwala engenza i-3PE coating, i-epoxy coating njll.Uma kukhona umbuzo sicela usithinte.
