Emikhakheni yokuthuthwa kukawoyela negesi, amaphrojekthi okulondolozwa kwamanzi kanye nokwakhiwa kwamapayipi asemadolobheni, ikhwalithi yongqimba lwangaphandle lokulwa nokugqwala kwamapayipi ensimbi inquma ngqo impilo yesevisi kanye nokuphepha kokusebenza kwamapayipi. Kuyini Ukugqoka Okungu-3LPE - Impendulo yalo mbuzo iyisisekelo sobuchwepheshe besimanje bokulwa nokugqwala kwamapayipi. Uhlelo lokumboza olunezingqimba ezintathu lwe-polyethylene (3LPE), olunezakhiwo zalo ezinhle kakhulu zemishini, ukumelana nokugqwala kanye nokuqina kwesikhathi eside, selube yisisombululo esilinganiselwe sokulwa nokugqwala kwamapayipi embonini yamapayipi ensimbi emhlabeni jikelele.
Uhlelo lokumboza i-3LPE ngokuvamile lwakhiwe ngezendlalelo ezintathu: ungqimba olungezansi oluyi-fused epoxy powder (FBE), lunamathela kahle futhi lumelana ne-cathodic; ungqimba oluphakathi lungqimba lokunamathela le-copolymer, olusekelwe kungqimba oluphezulu ungqimba olungezansi; ungqimba oluphezulu lungqimba lwe-polyethylene olukhishwe oluvikela uhlelo lokumboza ukuze luvikeleke kakhulu ngomshini kanye nokumelana okuphezulu komthelela. Isakhiwo esinjalo esihlanganisiwe esihlanganisiwe sivumela ungqimba lwe-3LPE ukuthi luvikele ngokuthembekile amapayipi ensimbi ezimweni eziyinkimbinkimbi ezingaphansi komhlaba nasezindaweni ezinzima amashumi eminyaka. Ekusetshenzisweni kwangempela, ukukhethaUbukhulu Bokumboza Okungu-3LPEkuyisixhumanisi esibalulekile sokuqinisekisa umphumela wokugqoka. Ngokuhambisana nezindinganiso ezifanele, ukugqoka kwe-PE okukhishwe ngezingqimba ezintathu okuvela efektri kanye nokugqoka kwe-PE okunezingqimba ezimbili noma eziningi kungasetshenziswa kumapayipi ensimbi kanye nokufakwa. Ngokuvamile, lokho okubizwa ngokuthi ubukhulu bokugqoka obuphelele kuklanywe ngendlela ehlukile kububanzi bepayipi lensimbi, indawo yesevisi, impilo yesevisi, kanye nezindinganiso zobunjiniyela.
Unganquma kanjani ubukhulu obufanele bengubo ye-3LPE? Amaphuzu alandelayo yizinto ezibalulekile okufanele uzicabangele:
Ububanzi bepayipi kanye nobukhulu bodonga
Kumapayipi anobubanzi obukhulu, abhekana nokucindezeleka okukhulu kwemishini ngesikhathi sokuthuthwa, ukwakhiwa, kanye nokugcwalisa emuva. Ngakho-ke, ukumbozwa okujiyile ngokuvamile kuyadingeka ukuze kumelwane nokuguguleka.
2. Indawo Yesevisi
Ezigabeni zamapayipi ezidlula emifuleni, ezindaweni ezinenhlabathi noma amatshe agqwala kakhulu, kufanele kukhethwe ungqimba olujiyile ukuze kuthuthukiswe ukumelana nokuklwebheka kanye nomkhawulo wokumelana nokugqwala.
3. Izidingo Zezindinganiso Nezincazelo
Amazwe ahlukene kanye nezindinganiso zemboni zinemithethonqubo ethile mayelana nobubanzi bokujiya kwezimbozo ze-3LPE. Ngokuvamile, ukujiya kwengqimba yangaphandle ye-polyethylene kuvame ukuba phakathi kuka-1.8mm no-3.7mm. Inani elithile lidinga ukuqinisekiswa ngokwezindinganiso zephrojekthi.
4. Izimo Zokwakha Nezokuthutha
Uma ipayipi lidinga ukuthuthwa ibanga elide noma imisebenzi yokuphakamisa izinto eziningi, ukwandisa ngokufanele ubukhulu bokumboza kunganciphisa ngempumelelo ingozi yomonakalo obangelwa yimithelela.
Enqubweni yokukhiqiza, umugqa wethu wokukhiqiza i-3LPE coating unamathela ngokuqinile ezindinganisweni zenqubo yokwakhiwa kwangaphambili kwefektri. Kusukela ekuphathweni komphezulu wepayipi lensimbi, ukufuthwa nge-epoxy powder, ukufakwa kwe-adhesive kuya ekumbozweni kwe-polyethylene extrusion, isinyathelo ngasinye sincike ekuqapheni kwenqubo kanye nokulinganiswa kobukhulu ukuqinisekisa ukuthi ukufana kwe-coating kuhlangabezana nezidingo zomklamo.
Ukuqonda "Kuyini Ukugqoka kwe-3LPE"futhi ukukhetha ngokwesayensi i-3LPE Coating Thickness kuyimfuneko ebalulekile yokuqinisekisa ukusebenza okuphephile kwesikhathi eside kohlelo lwamapayipi. Sizoqhubeka nokuhlinzeka amakhasimende omhlaba wonke ngezixazululo zokulwa nokugqwala kwamapayipi ensimbi ezihlangabezana namazinga futhi ezifanele izimo ezithile ngezinqubo ezinzima kanye nekhwalithi ethembekile.
