Heavy Hex Structural Bolts (ASTM F3125 F3125M)

Bakeng sa ts'ebetso e tšepahalang mererong ea kaho e boima, itšetleha ka liboutu tse boima tsa hex tse kopanang le maemo a ASTM F3125 le F3125M. Ka kaho ea tsona ea matla a phahameng a tšepe, tšireletso ea kutu, le ho nepahala ha boholo, liboutu tsena li tiisa likhokahano tse sireletsehileng le tse tšepahalang likopanong tsa tšepe tsa meralo.

Ho Tšepahala ho Sebopeho:Liboutu tse boima tsa hex tse tsamaellanang le maemo a ASTM F3125 le F3125M li entsoe ho fana ka ts'ebetso e tšepahalang lits'ebetsong tse batlang li le teng tsa kaho. Liboutu tsena li etselitsoe ho mamella meroalo e phahameng le ho netefatsa botsitso le bots'epehi ba likhokahano tsa bohlokoa likopanong tsa tšepe tsa sebopeho.

Matla a Lintho:E entsoe ka li-alloys tsa tšepe tse matla a phahameng, liboutu tsena li fana ka thepa e ikhethang ea ho tsitsa le ho kuta, e leng se etsang hore li tšoanelehe ho sebelisoa lits'ebetsong tsa tšepe tse tlas'a meroalo e boima le matla a matla. Kaho ea bona e matla e ntlafatsa ho tšoarella ka kakaretso le ho ts'epahala ha likopano tsa meralo.

Tšireletso ea Corrosion:Liboutu tse boima tsa hex li fumaneha ka lirafshoa tse thibelang kutu le lisebelisoa ho mamella maemo a thata a tikoloho, ho kenyelletsa ho pepesehela mongobo, lik'hemik'hale le likarolo tsa kantle. Sena se netefatsa ts'ebetso ea nako e telele mme se fokotsa kotsi ea mathata a amanang le kutu lits'ebetsong tsa meralo.

Ho nepahala ha Dimensional:Liboutu tsa ASTM F3125 le F3125M li hlahlojoa ka mokhoa o tiileng ho netefatsa mamello e nepahetseng le ho tsamaellana le likarolo tsa tšepe tsa sebopeho. Ho nepahala ha litekanyo tsena ho thusa ho lumellana hantle le ho lumellana nakong ea kopano, ho kenya letsoho ho boleng ba kakaretso le botšepehi ba mohaho.

Teko le Setifikeiti:Liboutu tsena li etsa liteko tse matla ho netefatsa thepa ea tsona ea mochini, sebopeho sa lik'hemik'hale, le ho latela lintlha tsa ASTM F3125 le F3125M. Setifikeiti se netefatsa hore liboutu li kopana le maemo a indasteri le litlhoko tsa ts'ebetso bakeng sa lits'ebetso tsa meralo.

Tataiso ea ho Kena:Mekhoa e nepahetseng ea ho kenya, ho kenyelletsa le mekhoa e nepahetseng ea ho tiisa le ho iketsa bolt, e bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea liboutu tse boima tsa hex. Ho latela litlhahiso tsa moetsi le mekhoa e metle ea indasteri ho netefatsa likhokahano tse sireletsehileng le tse tšepahalang likopanong tsa tšepe tsa sebopeho.

Litherisano le Tšehetso:Ho buisana le baenjiniere ba meralo le litsebi tsa ho tiisa ho khothaletsoa ha ho khethoa liboutu tse boima tsa hex bakeng sa merero ea kaho. Ba ka fana ka temohisiso ea bohlokoa le thuso ho khetha mofuta o nepahetseng oa bolt, boholo, le kereiti ho fihlela litlhoko tse ikhethileng tsa projeke le ho netefatsa bots'epehi ba sebopeho.

Lisebelisoa tse Bohlokoa:Liboutu tse boima tsa hex ke likarolo tsa bohlokoa lits'ebetsong tse fapaneng tsa tšepe, ho kenyeletsoa meaho, marokho, litora le merero ea meralo. Ts'ebetso ea bona e tšepahalang le ho latela litekanyetso tsa indasteri li kenya letsoho polokehong, botsitsong le botsitsong ba meaho ea bohlokoa.
