Ngokombono webanga lokushisa elinamathelayo, i-epoxy powder coating kanye ne-polyurea anti-corrosion coating ingasetshenziswa ngokujwayelekile endaweni yokugqwala kwenhlabathi esukela ku-30 ​​°C noma -25 °C kuya ku-100 °C, kuyilapho i-polyethylene yesakhiwo esinezendlalelo ezintathu. izinga lokushisa eliphezulu lesevisi ye-anti-corrosion coating ngu-70 ℃. Ngokuphathelene nokujiya kokumboza, ngaphandle kwezindwangu ezimbili zempuphu ye-epoxy, ukujiya kwezinye izimbotshana ezintathu konke kungaphezulu kuka-1mm, okufanele kuhlelwe ngokwesigaba sezingubo eziwugqinsi.
Enye yezinto ezijwayelekile zezinga lokumboza ipayipi izakhi zomshini nezomzimba ze-coating, okungukuthi, isimo sangempela esingahle sihlangabezane nenqubo yokwakhiwa kwepayipi, njengokucabangela ukugotshwa kwepayipi ngemva kokushisela nokuphakamisa eliphansi. umsele ngesikhathi kwakhiwa ipayipi elihamba ibanga elide. Izinto zenkomba yokumelana nezinga lokushisa eliphansi lokugoba zenziwe ngokuya ngamadayimitha amapayipi ahlukene, izinto zokumelana nomthelela we-coating zinqunywa ukulimala kokushayisana okubangelwa ukuthuthwa kwamapayipi nokugcwalisa emuva, ukumelana nokuklwebheka kanye nokumelana nokuklwebheka kwezingubo kunqunywa imihuzuko futhi imihuzuko lapho amapayipi enqanyulwa. Ukumelana nokugqoka, njll. Ngokombono walezi zakhiwo, kungakhathaliseki ukuthi i-epoxy powder coating, isakhiwo esinezingqimba ezintathu noma i-polyurea coating, zonke zisebenza kahle, kodwa mayelana nokuqina kokugqoka, i-polyethylene enezingqimba ezintathu inenani eliphakeme kakhulu lokumelana nomthelela, ngenkathi ufutha Inani elincane lokumelana nomthelela we-14.7J we-polyurea protective coating nalo lihle kakhulu.

Njengoba ukumbozwa kwamapayipi ade kakhulu kusetshenziselwa ukuhlanganiswa nokuvikelwa kwe-cathodic, umklamo weukufakwa kwepayipiizinkomba zinaka kakhulu ukusebenza kwe-anti-cathodic disbondment of the coating, ngaleyo ndlela kumisa amaphrojekthi wokunqamula ama-anti-cathodic wesikhathi esifushane, kucatshangelwa ukusetshenziswa kwamapayipi amabanga amade. Ngakho izinga lokushisa lisetha iphrojekthi yokushisa ephezulu ye-cathodic disbondment. Ngokombono wokumiswa kwenkomba, kusobala ukuthi inkomba ye-anti-cathodic disbondment ye-epoxy coating iphakeme, ukuhlukaniswa okuphezulu kwe-cathodic kungu-8.5mm ekamelweni lokushisa kwe-28d, futhi ukuhlukaniswa okuphezulu kwe-cathodic ekushiseni okuphezulu ngu-6.5mm ku-48h. . Izinkomba zokumboza i-urea zikhululekile, 12mm no-15m ngokulandelana.
