Ipayipi Elingenalutho :
Ipayipi libhekwa njengelingenalutho uma lingenayo into enamathela kuyo. Ngokujwayelekile, uma ukuginqika sekuqediwe endaweni yokugaya insimbi, impahla engenalutho ithunyelwa endaweni eklanyelwe ukuvikela noma ukumboza impahla nge-coating oyifunayo (okunqunywa izimo zomhlabathi zendawo okusetshenziswa kuyo). Ipayipi elingenalutho wuhlobo oluvame kakhulu lwepayipi elisetshenziswa embonini yokunqwabelanisa futhi livamise ukufakwa emhlabathini ukuze lisetshenziswe ngokwesakhiwo. Nakuba lungekho ucwaningo oluphathekayo oluphakamisa ukuthi ipayipi elingenalutho lizinze kakhulu ngokwemishini kunepayipi elimboziwe ukuze kufakwe inqwaba, ipayipi elingenalutho liyinto evamile embonini yesakhiwo.
Umbhobho ophehla ugesi :
I-galvanizing noma i-galvanization ingenye yezinhlobo ezidume kakhulu zokugqoka ipayipi lensimbi. Ngisho noma insimbi ngokwayo inenani lezinto ezinhle kakhulu uma kuziwa ekuphikiseni ukugqwala namandla aqinile, idinga ukumbozwa nge-zinc ukuze iphele kangcono. Ukugalela kungenziwa ngezindlela eziningi, kuye ngokutholakala kwendlela. Indlela ethandwa kakhulu, nokho, i-hot-dip noma i-batch dip galvanizing ehlanganisa ukucwiliswa kwepayipi lensimbi kubhavu we-zinc encibilikisiwe. Ukusabela kwe-metallurgical okwakhiwa ingxubevange yepayipi lensimbi kanye ne-zinc kudala isiphetho endaweni yensimbi enikeza ikhwalithi yokungagqwali engakaze ibe khona epayipini ngaphambili. Enye inzuzo ye-galvanizing izinzuzo zezindleko. Njengoba le nqubo ilula futhi ayidingi ukusebenza okuningi kwesibili nokucubungula ngemva kokucubungula, kube yinketho yokuzikhethela kubakhiqizi abaningi nezimboni.
I-FBE - I-Fusion Bonded Epoxy Powder Coating Pipe :
Lokhu kufakwa kwamapayipi kuhlinzeka ngokuvikeleka okuhle kakhulu kwamapayipi amancane kuya kwamakhulu anobubanzi obungamazinga okushisa aphakathi nendawo (-30C kuya ku-100C). Ukusetshenziswa kwayo kuvame ukusetshenziselwa amapayipi kawoyela, igesi, noma amapayipi amanzi. Ukunamathela okuhle kakhulu kuvumela ukumelana nokugqwala kwesikhathi eside nokuvikela ipayipi. I-FBE ingasetshenziswa njengesendlalelo esimbaxambili esihlinzeka ngezakhiwo eziqinile ezinciphisa umonakalo ngesikhathi sokuphatha, ukuthutha, ukufakwa, nokusebenza.
Ipayipi Lokuhlanganisa Isendlalelo Esilodwa Elihlanganisiwe Epoxy Elinqamula Ukubola : I-Electrostatic power coating;
Iphayiphu elivimbela ukubola kwe-Double Layer Fusion : Iphayiphu ye-epoxy ephansi ngenqindi, Bese kuba i-epoxy powder Surface.
3PE Epoxy Coating Pipe :
Ipayipi lensimbi eline-3PE Epoxy elinezingqimba ezi-3, uqweqwe lokuqala lwe-FBE, phakathi nendawo ungqimba olunamathelayo, ungqimba olungaphandle lwe-polyethylene. Ipayipi lokunamathisela le-3PE ngomunye umkhiqizo omusha othuthukiswe ngesisekelo se-FBE enamathela kusukela ngo-1980s, oqukethe izinto zokunamathisela kanye nezingqimba ze-PE(polyethylene). I-3PE ingaqinisa izakhiwo zemishini yepayipi, ukumelana nogesi okuphezulu, ukungangeni kwamanzi, ukugqokwa, ukulwa nokuguga.
Okwezendlalelo zokuqala i-epoxy eboshiwe ehlanganisiwe, ugqinsi bukhulu kuno-100μm. (FBE＞100μm)
Isendlalelo sesibili siyanamathela, okuwumphumela obopha izingqimba ze-epoxy neze-PE. (AD: 170~250μm)
Izendlalelo zesithathu yizingqimba ze-PE okuyi-polyethylene enezinzuzo zokulwa namanzi, ukumelana nogesi kanye nokulimala kwemishini. (φ300-φ1020mm)
Ngakho-ke, ipayipi lokugqoka le-3PE lihlanganiswe nezinzuzo ze-FBE kanye ne-PE. Okusetshenziswa kabanzi ekuthuthweni kwamapayipi amanzi, igesi namafutha.
