E 'ngoe ea melemo e ka sehloohong eaX60Pipe ea mohala oa SSAWke matla a eona a phahameng.Pipe ena e na le matla a fokolang a tlhahiso ea 60,000 psi, e leng se etsang hore e be se loketseng litlhoko tse phahameng tsa khatello ea oli le khase.Ts'ebetso ea spiral welding e boetse e tiisa hore phala e na le botenya ba lerako le ts'oanang, e leng ho eketsang matla a eona le ho tšepahala.

Ntle le matla, pipe ea mohala ea X60 SSAW e tsebahala ka ho sebetsa ha eona hantle le ho ba le tšusumetso e matla.Sena se bolela hore pipe e khona ho mamella likhatello le mathata a lipalangoang le ho kenngoa ntle le ho senya botšepehi ba eona.Sena se bohlokoa haholo bakeng sa liphaephe tsa oli, tseo hangata li hlokang ho haola le libaka tse thata le ho hlola litšitiso tse fapaneng nakong ea kaho.

Ho feta moo, phala ea X60 SSAW ha e bolae ke kutu haholo, e etsa hore e be tharollo e tšoarellang nako e telele le e theko e boima bakeng sa liphaephe tsa oli.Ts'ebetso ea spiral welding e etsa sebaka se boreleli le li-welds tse tsitsitseng, ho fokotsa kotsi ea ho bola le ho lelefatsa bophelo ba phala.Sena ke sa bohlokoa bakeng sa oliphaephes, tse pepesehetseng lintho tse senyang le maemo a tikoloho a ka senyang thepa ea boleng bo tlaase.

Kahong ea lipeipi tsa oli, polokeho le ts'epahalo li bohlokoa haholo.Pipe ea mohala oa X60 SSAW e tšoaea mabokose ohle mona, e fana ka tharollo e matla, e tšoarellang le e hananang le kutu e ka mamellang mathata a lipalangoang tsa oli le khase.Matla a eona a phahameng, ductility e babatsehang le ho tiea ha eona ho etsa hore e be khetho e tšepahalang bakeng sa merero e thata ka ho fetisisa ea lipeipi.

Ka kakaretso, pipe ea mohala oa X60 SSAW ke khetho ea pele ea liphaephe tsa oli ka lebaka la matla a eona a phahameng, ho tšoarella le ho hanyetsa kutu.Mokhoa oa eona oa ho cheselletsa liphaephe tse khonang ho mamella likhatello tse phahameng, libaka tse phephetsang le tikoloho e senyang, e leng se etsang hore e be tharollo e ka tšeptjoang le e bolokang chelete e ngata bakeng sa lipalangoang tsa oli le khase.Ha ho etsoa liphaephe tsa oli, ho khetha X60 spiral submerged arc welded pipeline pipe ke qeto ea ho netefatsa polokeho le ts'epo ea ts'ebetso eohle.
