Ka linako tse ling mathata a ho tjheseletsa a kopana le nakong ya ho kenngwa ha carbon steel tubes. Kahoo, mokhoa oa ho cheselletsa li-tubes? Re lokela ho ela hloko eng ha re cheselletsa li-tubes tsa carbon steel?

1. Ho chesoa ka khase
Ho cheselletsa khase ho ka sebelisoa bakeng sa ho cheselletsa, e leng ho kopanya khase e tukang le khase e tšehetsang mollo hammoho, ho e sebelisa e le mohloli oa mocheso oa lelakabe, ebe oa qhibiliha le ho omanya lipeipi hammoho.

2. Arc welding

Arc welding le eona e ka sebelisoa, ke hore, ho cheselletsa li-arc ho sebelisoa joalo ka mokhoa oa ho cheselletsa. Mohloli oa mocheso o kopanyang liphaephe hammoho. Mokhoa ona oa ho cheselletsa hangata o sebelisoa tlhahisong ea indasteri. Ho phaella mekhoeng e 'meli e ka holimo, pipeline e cheselitsoeng e ka boela ea sebelisa welding ea ho kopana,' me mokhoa o khethehileng oa ho chesetsoa o itšetlehile ka thepa le litlhoko tsa pipeline.

Tšepe e na le tšepe le k'habone e nang le lisebelisoa tse nyane tse fapaneng, joalo ka manganese, chromium, silicon, vanadium le nickel. Khabone e tlase e na le karolo ea 0.3 lekholong feela ea khabone, e etsang hore e be bonolo haholo ho e cheseletsa.
Khabone e bohareng e na le karolo ea 0.30 ho isa ho 0.60 lekholong ea carbon, le litšepe tse phahameng tsa carbon ho 0.61 ho ea ho 2.1 lekholong. Ha ho bapisoa, tšepe e entsoeng ka tšepe e na le karolo ea 3 lekholong ea carbon, e etsang hore ho be thata haholo ho cheselletsa.

Litlhokomelo tsa ho cheselletsa tube ea carbon steel:

1. Pele pipeline e chesetsoa, ​​​​ho hlokahala ho tlosa lithōle tsohle ka pipe. Ka mor'a hore mohaho o phethoe, ho ka sebelisoa letlapa le thibelang ho e tiisa ho thibela litšila hore li se ke tsa oela ho eona. Ka nako e ts'oanang, pele ho tjheseletsa, hoa hlokahala ho bentša matheba a oli karolong ea nozzle ho fihlela khanya e kang tšepe e hlaha.

2. Ka kakaretso, thepa ea liphaephe ha e le hantle ke spiral welded pipe, kahoo mokhoa oa ho tjheseletsa oa arc manual o ka khethoa. Bakeng sa mofuta ona oa phala, li-welds tsohle li hloka ho theoa ka tlase ka argon arc welding, 'me sekoaelo se lokela ho tlatsoa ka letsoho la arc welding.
