I-3PE anti-corrosioninsimbi ipayipi base impahla kuhlanganisa nekhono steel pipe, Kuvunguza steel ipayipi kanye iqonde umthungo steel pipe.I-polyethylene (3PE) enezingqimba ezintathu evimbela ukugqwala iye yasetshenziswa kakhulu embonini yamapayipi kawoyela ngenxa yokumelana nokugqwala kwayo okuhle, ukumelana nokugeleza komphunga wamanzi kanye nezakhiwo zemishini.

Ukwethulwa kwe-anti-corrosion layer ye-3PE anti-corrosion steel pipe:

I-anti-corrosion layer ye-3PE anti-corrosion steel pipe ibaluleke kakhulu empilweni yamapayipi agqitshiwe.Amanye amapayipi ezinto ezifanayo agqitshwa ngaphansi komhlaba amashumi eminyaka ngaphandle kokugqwala, kanti amanye avuza iminyaka eminingana.Kungenxa yokuthi zisebenzisa izingqimba ezingaphandle eziphikisana nokugqwala.

I-3PE anticorrosion ngokuvamile yakhiwa izendlalelo ezi-3:

Ungqimba olulodwa lwe-epoxy powder (FBE>100um)
I-adhesive enezendlalelo ezimbili (AD) 170～250um
Izendlalelo ezintathu ze-polyethylene (PE) 2.5-3.7mm

Ekusebenzeni kwangempela, izinto ezintathu zixutshwe futhi zihlanganiswe, futhi ngemva kokucubungula, zihlanganiswe ngokuqinile nepayipi lensimbi ukuze zenze ungqimba oluhle kakhulu lokulwa nokugqwala.Izindlela zokucubungula zivame ukuhlukaniswa zibe izinhlobo ezimbili: uhlobo olumazombezombe kanye nohlobo lokugoqa isikhunta.

Izinzuzo zepayipi lensimbi ye-3PE anti-corrosion:

Ukufakwa kwepayipi lensimbi le-3PE elwa nokugqwala ukuthi ungqimba olungezansi kanye nendawo yepayipi yensimbi ixhumene ne-epoxy powder anti-corrosion coating, futhi ungqimba oluphakathi luyi-copolymerized adhesive namaqembu asebenzayo egatsha.Ungqimba olungaphezulu luyi-high-density polyethylene anti-corrosion coating.I-3PE evikela ukugqwala kwepayipi lensimbi (i-polyethylene evimbela ukugqwala enezingqimba ezintathu) iyi-anti-corrosion entsha ekhiqizwa ngokuhlanganisa ngobuhlakani i-European 2PE anti-corrosion coating kanye ne-epoxy powder anti-corrosion steel pipe coating (FBE) esetshenziswa kabanzi I-America esenyakatho.Ipayipi lensimbi enamathela.Kuye kwaqashelwa futhi kwasetshenziswa emhlabeni wonke iminyaka engaphezu kweyishumi.

Inqubo yokuhlola ipayipi lensimbi ye-3PE anti-corrosion:

Okokuqala, ipayipi yensimbi elwa nokugqwala ihlolwe, futhi ipayipi yensimbi ihlolwe ngokuvumelana nezimo ezihlukahlukene ukuze ihlangabezane nemibandela yokwenza ipayipi yensimbi yokushisa ukushisa.Hlola ukuthi ipayipi lensimbi ligqwalile yini, hlola futhi ukhiphe i-embroidery epayipini lensimbi.Isinyathelo esilandelayo ukufaka ipayipi lensimbi elingagqwali kanye ne-anti-corrosion endaweni ye-polyethylene ukuze kwenziwe amapayipi.Ngemuva kokulungiswa kwekhanda, i-polyurethane foam ifakwe kuyo ukuze igcwalise ngokugcwele igebe ukuze igcwaliswe ngokugcwele.Ukuhlolwa kwamapayipi ensimbi okunqanda ukugqwala, nokuhlolwa kwemikhiqizo eqediwe yamapayipi ensimbi afaka ukushisa okushisayo aseqediwe.

I-3PE anti-corrosion steel pipe base base material idinga ukuhlola nokuqopha ipayipi lensimbi elingena endaweni yokungena yepayipi ngaphambi kokwelashwa okuqeda ukugqwala, nokudubula ukuqhuma nokususwa kokugqwala endaweni engaphandle yepayipi lensimbi, bese uhlola ukuthi ukuhlanzeka kwepayipi indawo engaphandle yepayipi yensimbi kanye nokujula kwephethini lehange kuhlangabezana nezidingo.Lezo ezingahlangabezani nezidingo ziyapholishwa futhi zilungiswe ngesandla ngesondo lokugaya, futhi i-tape paper isongwe ekugcineni kwepayipi, ukwelashwa ngothuli, ukushisa okuphakathi nendawo kuya ezingeni lokushisa elidingekayo, i-epoxy powder spraying, i-adhesive extruder side winding, i-PE extruder. ukusonga nokushiswa ohlangothini, ukunqanda ukugqwala Amapayipi apholiswa ngamanzi, futhi imikhiqizo efanelekayo iyafuthwa futhi imakwe, futhi isiteji kanye nokupakishwa kwamapayipi kulungele ukuthunyelwa.
