Amapayipi ensimbi okuvunguza asetshenziswa ngokuyinhloko njengamapayipi oketshezi kanye namapayipi okunqwabelanisa. Uma ipayipi lensimbi lisetshenziselwa ukukhipha amanzi, ngokuvamile lizobhekana nokwelashwa okuqeda ukugqwala endaweni engaphakathi noma yangaphandle. Izindlela zokwelapha ezivamile zokulwa nokugqwala zihlanganisa i-3pe anti-corrosion, i-epoxy coal tar anti-corrosion, ne-epoxy powder anti-corrosion. Linda, ngoba inqubo ye-epoxy powder dipping ihlushwa izinkinga zokunamathela, inqubo ye-epoxy powder dipping ayikaze ikhuthazwe. Manje, ngokuthuthuka ngempumelelo kwesisombululo esikhethekile se-phosphating sokucwiliswa kwe-epoxy powder, inkinga yokunamathela yenqubo yokucwilisa i-epoxy powder iye yanqotshwa okokuqala, futhi inqubo evelayo ye-epoxy powder dipping isiqalile ukuvela.

Ukuhlaziya izimbangela zokungalingani kogqinsi lwe-anti-corrosion coating kumapayipi ensimbi ezungezayo, ukujiya okungalingani kwamapayipi ensimbi asontekile angu-3PE kubonakala kakhulu ekushubeni okungalingani kwamaphoyinti okuhlola ohlangothini ngalunye olusatshalaliswa ngendlela eyindilinga. Izinga lomkhakha i-SY/T0413-2002 alinayo imithetho yokufana kogqinsi. Ibeka inani eliwugqinsi le-coating kodwa idinga ukuthi inani eliwugqinsi le-coating alikwazi ukuba ngaphansi kunevelu yogqinsi yephoyinti, kunevelu emaphakathi yamaphoyinti amaningi okuhlola.

Uma ukushuba kokumboza kungalingani ngesikhathi senqubo yokumboza yamapayipi ensimbi okuvunguza, izinto zokumboza zizochithwa nakanjani. Lokhu kungenxa yokuthi lapho ukushuba kwe-coating engxenyeni ye-thinnest ifinyelela ekucacisweni, ubukhulu bengxenye ewugqinsi buyoba bukhulu kunobukhulu bokucaciswa kwe-Coating. Ngaphezu kwalokho, ukunamathela okungalingani kungabangela kalula ukushuba kwe-coating engxenyeni encane kakhulu yepayipi yensimbi ukuthi yehluleke ukuhlangabezana nemibandela. Izizathu eziyinhloko zobukhulu obungalingani ngesikhathi senqubo yokukhiqiza ukukhishwa kwezinto ezingalingani kanye nokugoba kwepayipi lensimbi. Indlela esebenzayo yokulawula ukunamathela okungalingani kwamapayipi e-3PE anti-corrosion ukulungisa ama-extrusion dies amaningana ukwenza ukujiya kwe-anti-corrosion coating ezindaweni ezimbalwa kufane ngangokunokwenzeka kanye nokuvimbela amapayipi ensimbi angafanelekile ukuthi ambozwe ku-inthanethi.

Imibimbi ebusweni bokumbozwa: Ukukhipha kanye nokusonteka kwe-polyethylene epayipini lensimbi kudinga ukusetshenziswa kwe-silicone roller. Ukulungiswa okungalungile phakathi nale nqubo kungase kubangele imibimbi ebusweni bokugqoka. Ukwengeza, ukuphuka kwefilimu encibilikayo lapho izinto ze-polyethylene zishiya ukufa kokuphuma ngesikhathi senqubo ye-extrusion kuzophinde kukhiqize ukukhubazeka kwekhwalithi efana nemibimbi. Izindlela zokulawula ezihambisanayo zezimbangela zemibimbi zihlanganisa ukulungisa ubulukhuni nokucindezela kwe-rubber roller kanye ne-pressure roller. Kusukela kulo mbono, wandise ngokufanele inani le-polyethylene ekhishwayo ukuze ulawule ukuphuka kwefilimu encibilikayo.
