Yiziphi izinyathelo zokuphepha zokwakhiwa kwamapayipi e-polyurethane agqitshwe ngokuqondile?
Ngokuthuthuka kwemboni yamapayipi, izinto ezintsha zifakwa ohlwini kancane kancane emakethe.Njengomkhiqizo osebenza kahle embonini ye-thermal insulation, ipayipi le-polyurethane elingcwatshwe ngqo ekushiseni okushisayo linezici ezinhle kakhulu zokufakwa kwe-thermal kanye nokusebenza kahle komsebenzi.Ikona...Funda kabanzi -
Izinkinga ezivamile kanye nezixazululo ekwakhiweni kwamapayipi okushisa angcwatshwe ngokuqondile
Ipayipi eligqitshwe ngokuqondile lifakwa amagwebu ngenxa yokusabela kwamakhemikhali ezinto eziyinhlanganisela ye-polyether polyol esebenza kakhulu kanye ne-polymethyl polyphenyl polyisocyanate njengezisetshenziswa zokusetshenziswa.Amapayipi okufakwa okushisa angcwatshwe ngokuqondile asetshenziselwa ukufakwa kwe-thermal kanye namaphrojekthi okushisa abandayo ezinhlobonhlobo zasendlini ...Funda kabanzi -
Iziphakamiso zendlela yokucwecwa ye-3PE anti-corrosion coating
1.Ukuthuthukiswa kwendlela yokucwecwa eyimishini ye-3PE evimbela ukugqwala ① Thola noma uthuthukise okokusebenza okushisisa okungcono ukuze umiselele ithoshi yokusika igesi.Imishini yokushisisa kufanele ikwazi ukuqinisekisa ukuthi indawo yomlilo wesifutho inkulu ngokwanele ukushisisa yonke ingxenye yokwemboza ukuze isuswe ngesikhathi esisodwa...Funda kabanzi -
Mayelana ne-3PE anti-corrosion steel pipe enamathela indlela yokuxebuka
Indlela yokucwecwa kwemishini ye-3PE evimbela ukugqwala Okwamanje, ngesikhathi sokugcinwa kwepayipi legesi, indlela yokucwecwa ye-3PE anti-corrosion coating ihlongozwa ngokusekelwe ekuhlaziyweni kwesakhiwo kanye nenqubo yokuhlanganisa ye-3PE anti-corrosion coating [3- 4].Umqondo oyisisekelo wokucwecwa ...Funda kabanzi -
Ukusetshenziswa kwe-Polyurea Anticorrosion Coating on Pipeline
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-cor...Funda kabanzi -
Kuthuthukiswe ukumelana nokushisa okuphezulu kwe-3pe anticorrosion
Ngokuncipha kwamandla nezinsiza, imikhumbi yamapayipi ithutha igesi eyandayo, itiyela kanye neminye imikhiqizo kaphethiloli esezingeni eliphansi, futhi ukwakhiwa kwamapayipi olwandle nakho kuqhubeka ngokuqhubekayo.Ukuthuthukiswa akuzange kuphazamiseke.Okulandelayo yisingeniso sokuthi...Funda kabanzi
