Melemo ea spiral submerged arc welded pipe:

1. Kaho e sebetsang hantle:

Liphaephe tsa SSAW li na le moralo oa spiral weld o lumellang tlhahiso e sebetsang hantle le ho fokotsa nako ea tlhahiso.Tšobotsi ena e ikhethang e etsa hore e be khetho ea pele bakeng sa merero e meholo ea kaho e kang oli lelipeipi tsa khase, litsamaiso tsa phetiso ea metsi, le sethala sa ho cheka kantle ho naha.Ts'ebetso e tsoelang pele ea welding e tiisa boemo bo phahameng ba sebopeho sa sebopeho, ho eketsa nako e telele le bophelo ba tšebeletso ea pipe.

2. Matla a babatsehang le ho feto-fetoha ha maemo:

Sebopeho sa spiral sa pipe ea SSAW se eketsa matla a sona, se e lumella ho hanela likhatello tsa ka ntle le tsa ka hare.Liphaephe tsena li khona ho mamella maemo a feteletseng a sepakapaka, e leng se etsang hore li tšoanelehe ho sebelisoa ka holimo le ka tlaase ho mobu.Ho phaella moo, ho feto-fetoha ha liphaephe tsa SSAW ho li lumella ho fetoha habonolo le ho kenngoa libakeng tse sa tšoaneng, ho kenyelletsa le libaka tse makukuno le mobu o sa tsitsang.

3. Tharollo e bolokang litšenyehelo:

Mekhoa e tsoelang pele ea ho tjheseletsa e eketsa tlhahiso ha e ntse e fokotsa haholo bofokoli le litšenyehelo.Ho feta moo, liphaephe tse cheselitsoeng ka har'a metsi li fana ka matla le ho tšoarella nako e telele, li fokotsa litšenyehelo tsa tlhokomelo le tokiso bophelong bohle ba tsona, e leng se etsang hore e be khetho ea moruo bakeng sa indasteri.

Mathata a tobaneng le liphaephe tse cheselitsoeng ka har'a metsi:

1. Taolo ea boleng:

Ka lebaka la mekhoa e rarahaneng ea ho cheseletsa e amehang ho hlahiseng liphaephe tse cheselitsoeng ka har'a metsi, ho netefatsa boleng bo tsitsitseng ho thata.Haeba li-parameter tsa welding li sa laoloe ka nepo, ho tla ba le mefokolo ea welding joalo ka li-undercuts, pores le khaello ea fusion.Ho hlola phephetso ena, mehato e tiileng ea taolo ea boleng le litsamaiso tse tsoetseng pele tsa ho beha leihlo nakong ea ts'ebetso ea tlhahiso li bohlokoa.

2. Lethathamo la thibelo ea bophara ba liphaephe:

Leha liphaephe tse cheselitsoeng ka har'a metsi a spiral li loketse lisebelisoa tse kholo tsa bophara, li kanna tsa se tšoanele liindasteri tse hlokang boholo ba liphaephe tse nyane.Ts'ebetso ea tlhahiso e sebetsa hantle bakeng sa lipeipi tse kholoanyane tsa bophara, e leng se bakang phumaneho e fokolang bakeng sa merero e menyenyane joalo ka lipeipi tsa bolulo le lisebelisoa tse nyane tsa indasteri.Bakeng sa litlhoko tse joalo, mekhoa e meng ea theknoloji ea ho etsa liphaephe e lokela ho nkoa.

3. Ho roala ka holim'a metsi:

Phephetso e 'ngoe e tobaneng le indasteri ea liphaephe tsa SSAW ke ho netefatsa hore ho na le liaparo tse loketseng le tse tšoarellang ho sireletsa khahlanong le ho senya le ho apara.Kopo ea ho roala holim'a spiral e hloka lisebelisoa tse tsoetseng pele le boitseanape ho etsa bonnete ba ho koahela le ho khomarela.Ho roala ka holim'a metsi ho bohlokoa bakeng sa ho lelefatsa bophelo ba ts'ebeletso ea phala e kolobisitsoeng ea arc, haholo-holo libakeng tse thata.

Ha re phethela:

Liphaephe tse kentsoeng ka tlas'a metsi tsa Spiral li ipakile e le theknoloji e molemo haholo indastering ea sejoale-joale, e fanang ka ts'ebetso, matla le litšenyehelo tse tlase.Seam sa eona se ikhethang sa spiral weld se lumella tlhahiso e atlehileng le ho tšoarella ho eketsehileng, ho etsa hore e tšoanelehe bakeng sa merero e meholo ea kaho.Leha ho le joalo, bakeng sa katleho e tsoelang pele le ho amoheloa ho pharaletseng ha theknoloji ena ea tlhahiso, liphephetso tse kang taolo ea boleng, mefuta e fokolang ea bophara ba bophara, le ho roala holim'a metsi ho lokela ho rarolloa.Ka ho hlola liqholotso tsena ka tsoelo-pele ea theknoloji le tšebelisano-'moho ea indasteri, pipe e entsoeng ka metsi e nang le metsi a mangata e na le bokamoso bo tšepisang ba ho fetola le ho boloka mekhoa ea motheo ea bohlokoa ho pota lefatše.
