Ka tlas'a Arc Spiral Welded Tube Bakeng sa Mehala ea Khase
Liphaephe tse cheselitsoeng ka spiral li hlahisoa li sa khaotse 'me ka khopolo li ka hlahisa lipeipi tsa tšepe tse telele ka ho sa feleng.Ts'ebetso ena ea tlhahiso e fokotsa tahlehelo ea hlooho le mohatla ha e ntse e eketsa ts'ebeliso ea tšepe ka 6% ho isa ho 8%.Sena se tla fella ka ho boloka litšenyehelo le ho sebetsa hantle ho bareki ba rona.
Ea ronaspiral welded tubesfana ka maemo a phahameng a ho sebetsa ha a bapisoa le liphaephe tse kolobisitsoeng tsa seam tse tloaelehileng.Ho bonolo ho fapanyetsana le ho fetola mefuta e fapaneng, e etsa hore e be e loketseng merero e hlokang ho ikamahanya le maemo le ho e etsa.Ho feta moo, bokhoni ba mochini le boits'oaro ba li-tubes tsa spiral welded li li lumella ho kengoa ts'ebetsong habonolo libakeng tse fapaneng tsa indasteri.
