Lits'ebetsong tsa indasteri, haholo-holo lefapheng la oli le khase, botšepehi ba pipe ea tšepe bo bohlokoa. E 'ngoe ea litsela tse sebetsang ka ho fetisisa tsa ho netefatsa nako e telele le ho tšoarella ha liphaephe tsena ke ho sebelisa liphahlo tsa fusion bonded epoxy (FBE). Ho utloisisa litekanyetso tsa ho roala ha FBE ho bohlokoa ho mang kapa mang ea amehang ho rekoeng, ho kenya kapa ho lokisa lipeipi tsa metsi tsa tšepe le lisebelisoa.
Liphaephe tsa FBE li sebelisoa haholo-holo mefuteng e fapaneng ea lipeipi tsa tšepe, ho kenyeletsoa liphaephe tsa SSAW (Spiral Submerged Arc Welded), lipeipi tsa ERW (Electric Resistance Welded), LSAW (Longitudinal Submerged Arc Welded), lipeipi tse se nang moroallo, le lisebelisoa tse fapaneng tse kang li-elbows, li-tee le li-tee.

Ke engHo roala ha FBE?
Ho roala ha FBE ke phofo ea thermosetting epoxy e sebelisoang holim'a phala ea tšepe. Ts'ebetso ea kopo e kenyelletsa ho futhumatsa phala ho mocheso o itseng ebe o sebelisa phofo ea epoxy, e qhibilihisang ebe e theha maqhama a matla le holim'a phala ea tšepe. Ts'ebetso ena e etsa hore ho be le seaparo se boreleli, se tšoarellang le se thibelang lik'hemik'hale se ka mamellang maemo a thata a tikoloho.
Bohlokoa ba litekanyetso tsa ho roala FBE
Ho latela maemo a FBE ho bohlokoa ka mabaka a latelang:
1. Ho hanyetsa kutu: Mosebetsi o ka sehloohong oa ho roala FBE ke ho sireletsa tšepe ho senya. Litekanyetso tse amehang li netefatsa hore seaparo se sebelisoa ka nepo 'me se finyella litlhoko tse hlokahalang tsa botenya le ho khomarela ho fana ka tšireletso e nepahetseng.
2. Tiisetso ea Boleng: Ka ho latela litekanyetso tse behiloeng, bahlahisi ba ka netefatsa boleng ba lihlahisoa tsa bona. Sena ke sa bohlokoa haholo bakeng sa lik'hamphani tse hlahisang lipeipi tse ngata tsa tšepe, mohlala, k'hamphani e nang le thepa eohle ea li-yuan tse limilione tse 680, tlhahiso ea selemo ea lithane tse 400,000 tsa lipeipi tsa tšepe tse pota-potileng, le boleng ba tlhahiso ea li-yuan tse limilione tse likete tse 1,8.
3. Tumellano: Liindasteri tse ngata li tlas'a taolo e thata ea thepa le mekhoa eo li sebetsang ho eona. Ho latela melao ea FBE ho thusa lik'hamphani ho qoba litaba tsa molao le ho boloka botumo ba tsona ba mmaraka.

SenotloloLitekanyetso tsa ho roala FBE
Ha u nahana ka liphahlo tsa FBE, ho bohlokoa ho utloisisa lintlha tsa bohlokoa tsa ts'ebeliso ea tsona:
- ASTM D638: Tekanyetso ena e bonts'a thepa e tsitsitseng ea polasetiki (ho kenyeletsoa le liphahlo tsa FBE) ho netefatsa hore li khona ho mamella khatello ea maikutlo e sebelisoang.
- ASTM D3359: Tekanyetso ena e leka ho khomarela ha koae ho substrate, e leng bohlokoa ho netefatsa hore lesela la FBE le lula le tiile ha nako e ntse e ea.
- AWWA C213: Tekanyetso ena e sebetsana ka ho khetheha le litlhoko tsa liphaephe tsa epoxy tse kopantsoeng ka fusion bakeng sa phala ea metsi ea tšepe, e fanang ka tataiso bakeng sa kopo, tlhahlobo le tlhahlobo.
ha re phethela
Ka kakaretso, ho utloisisa litekanyetso tsa ho roala FBE ho bohlokoa ho mang kapa mang ea amehang indastering ea lipeipi tsa tšepe. E tsepamisitse maikutlo holim'a ts'ireletso ea kutu, netefatso ea boleng, le tumellano ea taolo, litekanyetso tsena li phetha karolo ea bohlokoa ho netefatsa bophelo ba ts'ebeletso le ho tšepahala ha lipeipi le lisebelisoa tsa tšepe. Lik'hamphani tse behang chelete e ngata ho latela litekanyetso tsena, tse kang tse nang le bokhoni bo matla ba tlhahiso le thepa, li ke ke tsa ntlafatsa boleng ba sehlahisoa feela empa hape li matlafatsa boemo ba tsona 'marakeng oa tlhōlisano. Ha tlhoko ea phala ea tšepe e tšoarellang le e tšepahalang e ntse e hola, bohlokoa ba ho roala FBE le litekanyetso tsa ts'ebeliso ea bona li tla tsoela pele ho hola.
