Umbhobho wensimbi we-TPEP ochasene ne-corrosive

Udonga lwangaphandle lwe-TPEP yombhobho wensimbi ochasene ne-corrosive yamkela inkqubo ye-3PE eshushu-enyibilikayo. (i-epoxy esezantsi, i-adhesive layer adhesive, i-polyethylene yangaphandle) i-anti-corrosive layer okanye i-polyethylene ye-single-layer (PE) enesakhiwo esinemigangatho emithathu yenziwe, udonga lwangaphakathi luthatha i-thermal yokutshiza i-epoxy powder ye-anti-corrosive mode, ipowder ifakwe ngokulinganayo kumphezulu womzimba wombhobho emva kokufudumeza okuphezulu kunye nokunyibilika, amandla okubambelela ombane kunye nobukhulu bengubo buphuculwe, kwaye ukuchasana kwe-bump kuphuculwe. ukumelana ne-corrosion, ulwakhiwo olulula, ukugquma kunye nokuqinisa ngaphakathi nangaphandle kombhobho ngaxeshanye, ukubunjwa kwefilimu yexesha elinye, elisebenza ngokubanzi kwi-corrosion yepayipi kwiinkalo ezahlukeneyo zobunjineli bobunjineli. Iinzuzo ze-TPEP zokunqanda ukubola kombhobho wentsimbi engenamthungo:

I-1, ixabiso lombhobho wentsimbi ye-TPEP libiza kakhulu kodwa izinga lokurhabaxa liphantsi, kwaye ububanzi be-TPEP umbhobho wentsimbi efunekayo buncinci kunombhobho wentsimbi we-ductile kwinqanaba lokuhamba okufanayo. Ngokomzekelo, ububanzi bombhobho wensimbi we-ductile kule projekthi yi-DN 1200mm, ipayipi yensimbi ye-TPEP kuphela i-DN 1000mm kumgca, ukuze kufakwe umbhobho wensimbi we-TPEP ogcina ngaphezu kombhobho wesinyithi we-ductile.

I-2, i-TPEP yentsimbi yombhobho yahlukile kumbhobho wentsimbi eqhelekileyo, yenziwe yangaphakathi kunye ne-anti-corrosion yangaphakathi, engenzi monakalo kumanzi okusela.

3, umbhobho wentsimbi we-TPEP unokuxhathisa ngamandla kwihamile yamanzi kunombhobho wentsimbi we-ductile.

I-4, Iimfuno zesiseko seentlobo ezimbini zemibhobho zifana ngokusisiseko.

5, Kulwakhiwo, umbhobho wensimbi we-TPEP udityanisiwe, kunye neemfuno eziphezulu zobugcisa kunye nenkqubela phambili yokwakhiwa kancinci. Umbhobho we-iron we-Ductile udibanisa, iimfuno zobugcisa ziqhelekileyo, inkqubela phambili yokwakhiwa iyakhawuleza, kodwa ii-buttresses ezininzi ziyafuneka.

6, Phantsi kweemeko zokusebenza ezifanayo, ububanzi bombhobho we-TPEP buncitshiswe ngaphezu kwalowo wombhobho wentsimbi ngomlinganiselo omnye, kunye nobungakanani bokumbiwa komhlaba, ukuhlala komhlaba okwexeshana, ubungakanani bokufakelwa kwemibhobho, kunye nokuvalwa kombhobho ohambelana nawo. zincitshiswe ngokuhambelanayo.
