Tsebisa:
Lefatšeng la lipeipi tsa tšepe,pipi e cheselitsoeng ka spirale tumme ka matla a eona a holimo, ho feto-fetoha ha maemo le ho baballa litšenyehelo.Liphaephe tsena li sebelisoa haholo liindastering tse fapaneng tse kang oli le khase, phetiso ea metsi, boenjiniere ba meralo le nts'etsopele ea meralo.Ho etsa bonnete ba ho kopanya ka mokhoa o se nang moeli le ts'ebetso e nepahetseng, ho bohlokoa ho utloisisa lintlha tse laolang peipi e cheselitsoeng ka spiral.Ho blog ena, re tla hlahloba lintlha tsa bohlokoa tsa liphaephe tse cheselitsoeng ka spiral, re hlakise boholo ba tsona, lisebelisoa le litlhoko tse ikhethang.
1. Boholo ba phala:
Liphaephe tse nang le li-spiral welded li fumaneha ka boholo bo fapaneng, ho netefatsa hore li lumellana le merero e fapaneng.Litekanyo hangata li kenyelletsa bophara ba kantle (OD), botenya ba lebota (WT), le bolelele.Ka ntle ho bophara ba lisenthimithara tse 20 ho isa ho tse 120, 'me botenya ba marako bo tloha ho 5 mm ho ea ho 25 mm.Mabapi le bolelele, likarolo tse tloaelehileng tsa lipeipi tse cheselitsoeng ka spiral ke limithara tse 6, limithara tse 8 le limithara tse 12 ho ikamahanya le litlhoko tse fapaneng tsa boenjiniere.
2. Lisebelisoa:
Khetho ea thepa ea phala ea SSAW e bohlokoa haholo 'me e itšetlehile haholo ka ts'ebeliso e reriloeng le maemo a tikoloho.Tšepe ea carbon e sebelisoa haholo bakeng sa matla a eona, ho tšoarella le ho hanyetsa ho bola.Ntle le moo, bakeng sa lits'ebetso tse ikhethileng tse hlokang ho hanyetsa kutu e matlafalitsoeng kapa ho hanyetsa mocheso o phahameng, liphaephe tse entsoeng ka tšepe ea alloy, tšepe e sa hloekang, kapa lisebelisoa tse ling tse ikhethang li ka sebelisoa.
3. Mokhoa oa tlhahiso:
Spiral welded pipe e hlahisoa ka mokhoa o tsoelang pele oa ho etsa spiral ho sebelisa likhoele tsa tšepe.Mokhoa ona o tiisa ho ts'oana ha botenya ba lerako, bophara le botšepehi ba sebopeho ka kakaretso.Khoeli e fepeloa ka har'a mochini, e e bopang hore e be sebopeho sa spiral se lakatsehang ebe e kopanya mathoko.Theknoloji e tsoetseng pele e amehang ts'ebetsong ea tlhahiso e lumella taolo e nepahetseng holim'a boholo le ts'ebetso ea pipe ea ho qetela.
4. Maemo a boleng:
Ho finyella litekanyetso tsa indasteri le ho netefatsa ho tšepahala ha liphaephe tse cheselitsoeng ka spiral, mehato e fapaneng ea netefatso ea boleng e kenngoa ts'ebetsong.Tsena li kenyelletsa ho latela maemo a amoheloang machabeng joalo ka API 5L, ASTM A252 le ISO 3183-3.Ho lumellana le litlhaloso tsena ho tiisa thepa ea mochine, sebopeho sa lik'hemik'hale, le ho nepahala ha phala.
5. Teko le tlhahlobo:
Ho netefatsa ts'ebetso e bolokehileng le ts'ebetso e bolokehileng ea phala e cheselitsoeng ea spiral, ho hlokahala liteko tse tiileng le mekhoa ea tlhahlobo.Sebelisa mekhoa ea tlhahlobo e sa senyeheng joalo ka tlhahlobo ea ultrasonic, tlhahlobo ea radiographic le tlhahlobo ea ho kenella ka mebala.Liteko tsena li lemoha mefokolo leha e le efe ea sebopeho kapa ho se lumellane ha lintho tse ka amang ts'ebetso le ho tšoarella ha phala.Ho feta moo, liteko tsa 'mele tse kang tlhahlobo ea hydrostatic li etsoa ho lekola matla le matla a liphaephe tse mamellang khatello.
Ha re phethela:
Liphaephe tse cheselitsoeng 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 boloka boleng ba tsona, ho tšepahala le ho lumellana le lisebelisoa tse fapaneng.Ho utloisisa litekanyo, lisebelisoa, mekhoa ea tlhahiso le litekanyetso tsa boleng tse amanang le pipe e entsoeng ka spiral welded ho bohlokoa ho netefatsa ts'ebetso e nepahetseng le tharollo e theko e tlaase.Ha thekenoloji e ntse e tsoela pele, litlhaloso tse laolang liphaephe tsena li ntse li ntlafala, li eketsa ts'ebetso ea tsona le ho feto-fetoha ha tsona liindastering tse sa tšoaneng.Ka ho nahana ka litlhaloso tsena, baenjiniere le litsebi ba ka etsa liqeto tse nang le tsebo mabapi le khetho le tšebeliso ea spiral welded pipe bakeng sa merero ea bona.
