Har'a li-plastiki tsohle tsa boenjiniere, HDPE e na le khanyetso e phahameng ka ho fetisisa ea ho apara 'me ke eona e bonahalang ka ho fetisisa.Ha boima ba limolek'hule bo phahame, ke moo thepa e sa sebetseng le ho feta, esita le ho feta lisebelisoa tse ngata tsa tšepe (tse kang carbon steel, stainless steel, bronze, joalo-joalo).Tlas'a maemo a ho senya ho matla le ho apara holimo, bophelo ba tšebeletso ke makhetlo a 4-6 a pipe ea tšepe le makhetlo a 9 a polyethylene e tloaelehileng;'Me katleho ea ho tsamaisa e ntlafatsoa ka 20%.Thepa e thibelang lelakabe le antistatic e ntle ebile e fihlela litlhoko tse tloaelehileng.Bophelo ba tšebeletso ea downhole bo feta lilemo tse 20, ka melemo e tsotehang ea moruo, ho hanyetsa tšusumetso, ho hanyetsa ho apara le ho hanyetsa habeli.
2. Pipe ea likhoerekhoere tsa PE
Pipe ea PE bakeng sa ho lahla likhoerekhoere e boetse e bitsoa phala e phahameng ea polyethylene, e bolelang HDPE ka Senyesemane.Mofuta ona oa peipi hangata o sebelisoa e le khetho ea pele bakeng sa boenjiniere ba masepala, e sebelisoang haholo indastering ea likhoerekhoere.Ka lebaka la ho hanyetsa ha eona, ho hanyetsa acid, ho hanyetsa kutu, ho hanyetsa mocheso o phahameng, ho hanyetsa khatello e phahameng le litšobotsi tse ling, butle-butle e ile ea nkela sebaka sa liphaephe tsa setso tse kang liphaephe tsa tšepe le liphaephe tsa samente 'marakeng, haholo-holo hobane phala ena e bobebe ka boima. mme e loketse ho kenya le ho falla, mme ke khetho ea pele ea lisebelisoa tse ncha.Basebedisi ba lokela ho ela hloko ka ho khetheha lintlha tse latelang ha ba khetha liphaephe tse entsoeng ka boitsebiso bona: 1. Ela hloko ka ho khetheha khetho ea lisebelisoa tse tala bakeng sa liphaephe tsa polasetiki.Ho na le likete tsa limaraka tsa lihlahisoa tse tala tsa polyethylene, 'me ho na le lisebelisoa tse tala tse tlase ho li-yuan tse likete tse' maloa 'marakeng.Lihlahisoa tse hlahisoang ke thepa ena e tala li ke ke tsa hahoa, ho seng joalo, tahlehelo ea ho tsosolosa e tla ba khōlō.2. Khetho ea bahlahisi ba liphaephe e tla itšetleha ka bahlahisi ba molao le ba litsebi.3. Ha u khetha ho reka liphaephe tsa PE, hlahloba bahlahisi hang-hang ho bona hore na ba na le matla a tlhahiso.
3. Pipe ea phepelo ea metsi ea PE
Liphaephe tsa PE bakeng sa phepelo ea metsi ke lihlahisoa tse nkelang sebaka sa lipeipi tsa tšepe tsa setso le lipeipi tsa metsi a nooang tsa PVC.
Pipe ea phepelo ea metsi e tlameha ho jara khatello e itseng, 'me hangata ho khethoa resin ea PE e nang le boima bo phahameng ba molek'hule le thepa e ntle ea mochini, joalo ka HDPE resin.Resin ea LDPE e na le matla a fokolang a matla, khatello e fokolang ea khatello, ho se tsitse ho fokolang, botsitso bo fokolang nakong ea ho bōptjoa le ho kopanya ho thata, kahoo ha e tšoanelehe e le thepa ea phala ea khatello ea metsi.Leha ho le joalo, ka lebaka la index ea eona e phahameng ea bohloeki, PE, haholo-holo HDPE resin, e fetohile ntho e tloaelehileng bakeng sa ho hlahisa liphaephe tsa metsi a nooang.HDPE resin e na le viscosity e tlaase ea ho qhibiliha, metsi a matle le ho sebetsa habonolo, kahoo index ea eona ea ho qhibiliha e na le mefuta e mengata ea khetho, hangata MI e pakeng tsa 0.3-3g / 10min.
