Heavy Hex Bolts [Letlapa la 3] (ASTM A307)

Bakeng sa ho tiisa ka matla le ho ts'epahala lits'ebetsong tsa mosebetsi o boima, tšepa liboutu tse boima tsa hex tse tsoang ASTM A307. Ka lisebelisoa tsa bona tsa boleng bo holimo, tlhahiso e nepahetseng, le liphaephe tse sa jeng, liboutu tsena li fana ka ts'ebetso e ikhethang le ho tšoarella nako e telele.

Mohlala:ASME B 18.2.1

Litharollo tse matla tsa ho tiisa:Liboutu tse boima tsa hex, joalo ka ha li bonts'itsoe ho Lethathamo la 3 (ASTM A307), li entsoe ho fana ka tiiso e tiileng le e tšepahalang lits'ebetsong tse fapaneng. Ka mohaho oa tsona o tiileng le boholo ba hlooho e kholoanyane, liboutu tsena li fana ka matla a phahameng le ho tšoarella, ho etsa hore e be tse loketseng bakeng sa likopano tse boima tsa meralo le tsa mechine.

Lisebelisoa tsa boleng bo holimo:E entsoe ka tšepe e matla e phahameng ea carbon, liboutu tse boima tsa hex tse tsoang ASTM A307 li khomarela litekanyetso tse thata tsa boleng, li netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele. Thepa ea bona e ikhethang e ba etsa hore ba se ke ba khathala, ba se ke ba fetoha le khatello ea maikutlo, esita le libakeng tse boima.

Precision Manufacturing:Bolt e 'ngoe le e' ngoe e boima ea hex e etsa lits'ebetso tse nepahetseng tsa tlhahiso ho fihlela ho nepahala ha maemo le litlhoko tse tiileng tsa mamello. Tlhokomelo ena ea lintlha e netefatsa boleng bo tsitsitseng le ho lekana hantle, ho bohlokoa bakeng sa ho tiisa ka mokhoa o sireletsehileng le o tsitsitseng lits'ebetsong tsa bohlokoa.

Lisebelisoa tse fapaneng:Ka mefuta e mengata ea boholo ba likhoele, bolelele le bophara bo fumanehang, liboutu tse boima tsa hex ke li-fasteners tse fapaneng tse loketseng liindasteri le lits'ebetso tse fapaneng. Ho sa tsotellehe hore na li sebelisoa mohahong, mehahong ea motheo, kapa mechine, liboutu tsena li fana ka matla a ka tšeptjoang a ho tiisa le tlhophiso ea botšepehi.

Corrosion Resistance:Ho matlafatsa ho tšoarella le ho phela nako e telele, liboutu tse boima tsa hex li ka koaheloa ka lithapo tse thibelang kutu joalo ka zinc plating kapa hot-dip galvanization. Liaparo tsena li fana ka tšireletso e sebetsang khahlanong le mafome le ho senya, ho lelefatsa bophelo ba tšebeletso ea liboutu le mehaho eo ba e tšehetsang.

Ts'ebetso e netefalitsoeng:Liboutu tse boima tsa hex tse tsamaellanang le ASTM A307 li etsa liteko tse matla le setifikeiti ho netefatsa hore li latela maemo a indasteri. Ka ho khetha liboutu tse netefalitsoeng, basebelisi ba ka ba le ts'epo ts'ebetsong ea bona le ts'epahalong ea bona, esita le libakeng tse hlokang le tse phahameng tsa khatello ea maikutlo.

Therisano ea Setsebi:Ha u khetha liboutu tse boima tsa hex bakeng sa lits'ebetso tse ikhethileng, ho bohlokoa hore u buisane le litsebi tsa ho itima lijo tse ka fanang ka tataiso mabapi le ho khetha boholo bo nepahetseng ba bolt, kereiti le ho roala bakeng sa ts'ebetso e nepahetseng le bophelo bo bolelele.
