I-3PE anti-corrosionumbhobho wentsimbi isiseko impahla ibandakanya ingenamthungo umbhobho yentsimbi, umbhobho spiral intsimbi kunye nentsimbi yomthungo ngqo umbhobho.I-polyethylene (3PE) ye-anti-corrosion ye-anti-corrosion isetyenziswe ngokubanzi kwishishini lemibhobho ye-oyile ngenxa yokunganyangeki kwayo kakuhle, ukunyanzeliswa komphunga wamanzi kunye neempawu zomatshini.

Ukuqaliswa kwe-anti-corrosion layer ye-3PE anti-corrosion iron pipe:

I-anti-corrosion layer ye-3PE anti-corrosion iron pipe ibaluleke kakhulu kubomi bemibhobho engcwatywe.Eminye imibhobho yesixhobo esifanayo ingcwatywa ngaphantsi komhlaba amashumi eminyaka ngaphandle kokubola, kwaye eminye ivuza iminyaka emininzi.Kungenxa yokuba basebenzisa iileya ezahlukeneyo zangaphandle ezichasene nokuhlwa.

I-3PE anticorrosion idla ngokuqulunqwa ngamaleko ama-3:

Umaleko omnye womgubo we-epoxy (FBE> 100um)
Isincamathelisi esinemigangatho emibini (AD) 170～250um
Imigangatho emithathu ye-polyethylene (PE) 2.5～3.7mm

Ekusebenzeni kwangempela, izinto ezintathu zixutywe kwaye zidibaniswe, kwaye emva kokucutshungulwa, zihlanganiswe ngokuqinileyo kunye nombhobho wensimbi ukuze zenze i-anti-corrosion layer.Iindlela zokulungisa zahlulwe ngokubanzi zibe ziindidi ezimbini: uhlobo lokujija kunye nohlobo lokusonga lokungunda.

I-3PE iluncedo lombhobho wentsimbi echasene nomhlwa:

Ukugquma kombhobho wensimbi ye-3PE ye-anti-corrosion kukuba umgangatho ophantsi kunye nomphezulu wepayipi wentsimbi udibene ne-epoxy powder anti-corrosion coating, kwaye umaleko ophakathi yi-adhesive copolymerized kunye namaqela asebenzayo amasebe.Umaleko ongaphezulu yi-high-density polyethylene anti-corrosion coating.I-3PE anti-corrosion yentsimbi yombhobho yokwaleka (i-polyethylene ye-anti-corrosion ye-anti-corrosion coating) yinto entsha yokuchasana ne-corrosion eveliswa ngobuchule bokudibanisa i-European 2PE anti-corrosion coating kunye ne-epoxy powder anti-corrosion yensimbi yombhobho yokwaleka (FBE) esetyenziswa ngokubanzi Amantla Emelika.Ukugquma kombhobho wentsimbi.Sele iqatshelwe kwaye isetyenziswa kulo lonke ihlabathi ngaphezu kweminyaka elishumi.

Inkqubo yokuhlola umbhobho wentsimbi ye-3PE echasene nomhlwa:

Okokuqala, umbhobho wensimbi ochasene ne-corrosion uhlolwe, kwaye umbhobho wensimbi uhlolwe ngokweemeko ezahlukeneyo ukuze uhlangabezane neemeko zokwenza umbhobho wensimbi we-thermal insulation.Khangela ukuba umbhobho wensimbi ugqwalile, khangela kwaye ususe i-embroidery kwipayipi yensimbi.Isinyathelo esilandelayo kukubeka i-rust-proof kunye ne-anti-corrosion iron pipe kwi-casing ye-polyethylene yokwenza umbhobho.Emva kokuba intloko ilungiswe, i-polyurethane foam ifakwe kuyo ukuze igcwalise ngokupheleleyo i-gap ukuze izaliswe ngokupheleleyo.Ukuhlolwa kwemibhobho yetsimbi echasene ne-corrosion, kunye nokuhlolwa kweemveliso ezigqityiweyo kwimibhobho yensimbi yokufakelwa kwe-thermal egqityiweyo.

I-3PE anti-corrosion steel pipe base base ifuna ukujonga kwaye irekhode umbhobho wentsimbi ongena kwiqonga lokungena kumbhobho phambi konyango lokuchasa ukudumba, kunye nokudubula ukuqhushumba kunye nokususwa komhlwa kumphezulu ongaphandle wombhobho wentsimbi, kwaye emva koko ukhangele ukuba ucoceko lwe indawo yangaphandle yombhobho wensimbi kunye nobunzulu bepateni ye-anchor ihlangabezana neemfuno.Ezo zingahlangabezani neemfuno zigudiswe kwaye zilungiswe ngesandla ngevili lokusila, kunye nephepha letape lijikelezwe ekupheleni kombhobho, unyango lothuli, ukufudumeza okuphakathi kobushushu obufunekayo, i-epoxy powder yokutshiza, i-adhesive extruder side winding, i-PE extruder. i-side winding and burning, anti-corrosion Imibhobho ipholile ngamanzi, kwaye iimveliso ezifanelekileyo zifafazwa kwaye ziphawulwe, kwaye iqonga kunye nokupakishwa kwemibhobho ilungele ukuthunyelwa.
