Heavy Hex Structural Bolts (ASTM A 325 ASTM A 490)

Bakeng sa bots'epehi bo phahameng ba sebopeho le ts'epahalo mererong ea kaho, tšepa liboutu tse boima tsa hex tse tsamaellanang le litekanyetso tsa ASTM A325 le A490. Ka kaho ea tsona ea matla a phahameng a tšepe, ho hanyetsa boemo ba leholimo, le ho lumellana ka thata le maemo a indasteri, liboutu tsena li fana ka ts'ebetso e tšepahalang lits'ebetsong tsa bohlokoa tsa meralo.

Sebopeho sa Botšepehi:Liboutu tse boima tsa hex tse tsamaellanang le ASTM A325 le ASTM A490 li entsoe ho fana ka bots'epehi bo ikhethang ba merero ea kaho le meaho. Liboutu tsena li etselitsoe ho mamella meroalo le likhatello tse phahameng, ho etsa hore li tšoanelehe bakeng sa lits'ebetso tsa bohlokoa moo polokeho le ts'epo e leng tsa bohlokoa.

Tšepe e Matla a Phahameng:E entsoe ka li-alloys tsa tšepe tse matla a phahameng, liboutu tsena li fana ka thepa e phahameng ea tensile le matla a ho kuta, ho netefatsa ts'ebetso e tšepahalang likhokahanong tsa meralo. Kaho ea tsona e matla e li etsa tse loketseng ho sebelisoa marokhong, meahong, litorang le meahong e meng e jereng meroalo e imetsoeng ke meroalo e boima le matla a matla.

Maemo a Leholimo:Liboutu tse boima tsa hex li etselitsoe ho hanela maemo a tikoloho joalo ka kutu, mafome le maemo a sepakapaka. Ka liphahlo le thepa ea boikhethelo, liboutu tsena li fana ka nako e telele le ho ts'epahala, esita le libakeng tse thata tsa kantle le lits'ebetsong tsa leoatle.

Matla a ho Laela Pele le ho Tlama:Ka ho fana ka boemo bo phahameng ba matla a ho laela le ho koala, liboutu tsa ASTM A325 le A490 li thusa ho boloka botšepehi bo kopaneng le ho thibela ho lokoloha tlas'a meroalo e matla le ho thothomela. Sena se netefatsa hore dikgokelo tsa meralo di dula di bolokehile ha nako e ntse e tsamaya, ho fokotsa kotsi ya ho hloleha ha meralo le ho netefatsa polokeho ya basebetsi le thepa.

Tumellano le Setifikeiti:Ho ea ka litekanyetso tsa indasteri, liboutu tse boima tsa hex li etsa liteko tse matla le setifikeiti ho netefatsa ho latela litlhaloso tsa ASTM A325 le A490. Sena se kenyelletsa tlhahlobo ea mochini, tlhahlobo ea lik'hemik'hale, le licheke ho netefatsa ts'ebetso ea liboutu le bots'epehi, ho fana ka netefatso ea boleng le ts'epahalo.

Mehopolo ea Kemiso:Mekhoa e nepahetseng ea ho kenya, ho kenyelletsa le mekhoa e nepahetseng ea ho tiisa le ho etsa boikaketsi ba bolt, e bohlokoa ho eketsa ts'ebetso ea liboutu tse boima tsa hex. Ho latela likhothaletso tsa moetsi le mekhoa e metle ea indasteri ho netefatsa ts'ebetso e nepahetseng ea bolt le bots'epehi ba sebopeho.

Therisano ea Setsebi:Ha u hlakisa liboutu tse boima tsa hex bakeng sa merero ea kaho, ho bohlokoa ho buisana le baenjiniere ba meralo le litsebi tsa ho tiisa. Ba ka fana ka tataiso mabapi le ho khetha mofuta o nepahetseng oa bolt, boholo, le kereiti ho fihlela litlhoko tse ikhethileng tsa kopo le ho netefatsa ho latela litekanyetso tsa indasteri.

Lisebelisoa tse Bohlokoa:Liboutu tse boima tsa hex ke likarolo tsa bohlokoa makaleng a kaho le a meaho, moo li bapalang karolo ea bohlokoa ho netefatsa polokeho le botsitso ba tikoloho e hahiloeng. Ho tloha ho marokho le meaho ho ea litsing tsa indasteri le meaho ea lipalangoang, liboutu tsena li kenya letsoho ho ts'ireletseho ea sebopeho le botsitso ba merero ea bohlokoa ea meralo ea motheo.
