Ntlafatso ea Meralo ea Likhoerekhoere ka ho Sebelisa Liphaephe tsa Spiral Submerged Arc (SSAW)

Tlhaloso e Khutšoanyane:

Karolo ena ea Tekanyetso ea Europe e totobatsa maemo a tekheniki a phano bakeng sa likarolo tse batang tse cheselitsoeng, tse se nang letho tsa libōpeho tse chitja, tsa lisekoere kapa tse khutlonnetsepa, 'me e sebetsa likarolong tse entsoeng ka masoba tse batang ntle le ho phekoloa ka mocheso o latelang.

Cangzhou Spiral Steel Pipes Group Co., Ltd e fana ka karolo e se nang letho ea liphaephe tse chitja tsa tšepe bakeng sa sebopeho.

Kakaretso ea pipi e kolobisitsoeng ea arc e kentsoeng ka metsing:

Pipe ea arc e kentsoeng ka metsing, eo ka tloaelo e tsejoang e le spiral submerged arc welded pipe, e thehoa ka ho roala tšepe e kolobisitsoeng e chesang hore e be sebopeho sa spiral le ho e tjheseletsa haufi le seam se cheselletsang ho sebelisa mokhoa oa ho tjheseletsa oa arc o ka tlas'a metsi. Liphaephe tsena li fana ka boemo bo phahameng ba ho tiea, matla le ho hanyetsa ho bola, ho etsa hore e be tse loketseng merero ea bohlokoa ea mekhoa ea motheo e kang ea likhoerekhoere.

Melemo ea phala ea SSAW lits'ebetsong tsa likhoerekhoere:

1. Ho tšoarella nako e telele: Lipeipi tse cheselitsoeng ka tlas'a metsi a Spiral li entsoe ka tšepe ea boleng bo holimo 'me li tšoarella nako e telele. Ba na le matla a ho mamella meroalo e boima le maemo a feteletseng a ka tlas'a lefatše, ho netefatsa bophelo bo bolelele ba tšebeletso bakeng sa liphaephe tsa likhoerekhoere.

2. Ho hanyetsa ha kutu: Ts'ebetso ea ho kenya galvanizing ea hot-dip e eketsa lesela le eketsehileng la tšireletso peiping e kolobisitsoeng ea arc, e etsa hore e se ke ea bola haholo. Thepa ena e bohlokoa bakeng sa litsamaiso tsa likhoerekhoere hobane hangata li kopana le tikoloho e mabifi ea lik'hemik'hale le ea baeloji.

3. Moralo o sa dutseng: Peipi e tjheseditsweng ka tlasa metsi a spiral e etswa ka mokgwa o tswelang pele wa welding ho netefatsa sebopeho se sa duleng. Tšobotsi ena e thibela monyetla leha e le ofe oa ho kenella kapa ho lutla, ka hona ho fokotsa monyetla oa ho silafala ha mobu le tlhokahalo ea litokiso tse theko e boima.

4. Ho feto-fetoha ha maemo le ho feto-fetoha ha maemo: Pipe e entsoeng ka metsi e nang le arc e nang le metsi a mangata e ka etsoa hore e lumellane le mefuta e sa tšoaneng ea li-diameter, bolelele le matsoapo, e leng ho lumellang ho feto-fetoha ho hoholo ha moralo oa tsamaiso ea likhoerekhoere. Ba khona ho ikamahanya habonolo le liphetoho tsa sebaka le tsela, ba etsa bonnete ba hore metsi a litšila a phalla hantle esita le litsing tse rarahaneng tsa likhoerekhoere.

5.

Boemo ba bona bo bobebe bo fokotsa litšenyehelo tsa ho tsamaisa thepa 'me ho bonolo ho e kenya, ho fokotsa litlhoko tsa basebetsi. Ho phaella moo, bophelo ba eona bo bolelele ba tšebeletso le litlhoko tse fokolang tsa tlhokomelo li tlatsetsa katlehong ea nako e telele ea litšenyehelo.
