Hlahisa:
Lefatšeng la liphaephe tsa tšepe,phala e tjheseletsoeng ka spirale tumme ka matla a eona a phahameng, ho tenyetseha le ho boloka litšenyehelo hantle. Liphaephe tsena li sebelisoa haholo indastering e fapaneng joalo ka oli le khase, phetiso ea metsi, boenjiniere ba meaho le nts'etsopele ea meralo ea motheo. Ho netefatsa kopanyo e se nang sekoli le ts'ebetso e ntle ka ho fetisisa, ho bohlokoa ho utloisisa litlhaloso tse laolang phaephe e kopantsoeng ka spiral. Ho blog ena, re tla hlahloba lintlha tsa bohlokoa tsa litlhaloso tsa phaephe e kopantsoeng ka spiral, re hlakise boholo ba tsona, thepa le litlhoko tse itseng.
1. Boholo ba phaephe:
Liphaephe tse tjheseditsweng ka moya di fumaneha ka boholo bo fapaneng, ho netefatsa hore di tsamaellana le merero e fapaneng. Ditekanyo hangata di kenyelletsa bophara ba kantle (OD), botenya ba lebota (WT), le bolelele. Bophara ba kantle bo tloha ho di-inchi tse 20 ho isa ho tse 120, mme botenya ba lebota bo tloha ho 5 mm ho isa ho 25 mm. Mabapi le bolelele, dikarolo tse tlwaelehileng tsa diphaephe tse tjheseditsweng ka moya ke dimithara tse 6, dimithara tse 8, le dimithara tse 12 ho ikamahanya le ditlhoko tse fapaneng tsa boenjiniere.
2. Lisebelisoa:
Khetho ea thepa ea phaephe ea SSAW e bohlokoa haholo 'me e itšetlehile haholo-holo ka ts'ebeliso e reriloeng le maemo a tikoloho. Tšepe ea khabone e sebelisoa haholo bakeng sa matla a eona, ho tšoarella ha eona, le ho hanyetsa ho bola. Ho phaella moo, bakeng sa lits'ebetso tse itseng tse hlokang ho hanyetsa ho bola ho matlafalitsoeng kapa ho hanyetsa mocheso o phahameng, liphaephe tse entsoeng ka tšepe ea motsoako, tšepe e sa hloekang, kapa thepa e 'ngoe e ikhethang li ka sebelisoa.
3. Ts'ebetso ea tlhahiso:
Phaephe e welletsoeng ka spiral e hlahisoa ka mokhoa o tsoelang pele oa ho etsa spiral ho sebelisoa likhoele tsa tšepe. Mokhoa ona o netefatsa ho tšoana ha botenya ba lebota, bophara le botšepehi ba sebopeho ka kakaretso. Khoele e fepeloa ka har'a mochini, e e bopang ka sebopeho se lakatsehang sa spiral ebe e kopanya mathoko hammoho. Mahlale a tsoetseng pele a amehang ts'ebetsong ea tlhahiso a lumella taolo e nepahetseng holim'a boholo le ts'ebetso ea phaephe ea ho qetela.
4. Maemo a boleng:
Ho fihlela maemo a indasteri le ho netefatsa botshepehi ba diphaephe tse welditsweng ka spiral, mehato e fapaneng ya netefatso ya boleng e kenngwa tshebetsong. Tsena di kenyeletsa ho latela maemo a tsebahalang matjhabeng jwalo ka API 5L, ASTM A252 le ISO 3183-3. Ho latela dipehelo tsena ho netefatsa thepa ya mechini, sebopeho sa dikhemikhale, le ho nepahala ha phala.
5. Teko le tlhahlobo:
Ho netefatsa botšepehi le ts'ebetso e sireletsehileng ea phaephe e welletsoeng ka spiral, ho hlokahala mekhoa e tiileng ea liteko le tlhahlobo. Sebelisa mekhoa ea liteko e sa senyeheng joalo ka tlhahlobo ea ultrasound, tlhahlobo ea radiographic le tlhahlobo ea ho kenella ka mebala. Liteko tsena li lemoha mefokolo efe kapa efe ea sebopeho kapa ho se lumellane ha thepa ho ka amang ts'ebetso le ho tšoarella ha phaephe. Ho phaella moo, liteko tsa 'mele tse kang tlhahlobo ea hydrostatic li etsoa ho lekola matla le bokhoni ba ho jara khatello ba liphaephe.
Ha re phethela:
Liphaephe tse tjheseletsoeng ka spiral li fana ka melemo e mengata ho feta mefuta e meng ea liphaephe 'me litlhaloso tsa tsona li bapala karolo ea bohlokoa ho bolokeng boleng ba tsona, botšepehi le ho lumellana le lits'ebetso tse fapaneng. Ho utloisisa litekanyo, thepa, lits'ebetso tsa tlhahiso le maemo a boleng a amanang le phaephe e tjheselitsoeng ka spiral ho bohlokoa ho netefatsa ts'ebetso e ntle le tharollo e theko e tlase. Ha theknoloji e ntse e tsoela pele ho hatela pele, litlhaloso tse laolang liphaephe tsena li ntse li ntlafala, li eketsa bokhoni ba tsona le ho tenyetseha ha tsona liindastering tse fapaneng. Ka ho nahana ka litlhaloso tsena, baenjiniere le litsebi ba ka etsa liqeto tse nang le tsebo mabapi le khetho le tšebeliso ea phaephe e tjheselitsoeng ka spiral bakeng sa merero ea bona.
