ASTM A490 na ASTM A325 Bolts

Byombi ASTM A490 na ASTM A325 Bolts ziremereye cyaneBolt. Waba uzi itandukaniro riri hagati ya ASTM A490 na ASTM A325? Uyu munsi, reka tubiganireho.

Igisubizo cyoroshye nuko ASTM A490 iremereye cyane ya hexagonal bolts ifite imbaraga zisabwa kurenza A325 ziremereye cyane. Bolt ya A325 ifite imbaraga zingana zingana na 120ksi, mugihe A490 bolts ifite imbaraga zingana zingana na 150-173ksi.

Usibye ibi, hari ibindi bitandukanye bitandukanye hagati ya A490 na A325.

Ibikoresho

• A325 yubatswe yubatswe ikozwe mumashanyarazi akomeye yo hagati ya karubone, hamwe nibisanzwe bikunze kuboneka mubwubatsi
• A490 yubatswe ikozwe mubyuma bikomeye-bitunganijwe neza
• A325 yubatswe irashobora kubaashyushyekandi usanga mubisanzwe hamwe nicyo gipfukisho. A325 ya galvanised bolts irazwi cyane kubera imiterere irwanya ruswa.
• A490 yubatswe irakomeye, ntishobora gushyuha-gushiramo imbaraga kubera izo mbaraga. Bitewe n'imbaraga nyinshi zingana na A490, bafite ibyago byo kwinjiza hydrogène bitewe na galvanizing. Ibi birashobora kuganisha kunanirwa hakiri kare kandi birashobora guhinduka muburyo budasanzwe.

Kwambara

Iboneza

Byombi A3125 na A325 bigwa munsi ya ASTM F490 kandi bikoreshwa muburyo bwimiterere. Mubisanzwe, ibimera byubatswe ninshingano ziremereye za hex cyangwa kugenzura impagarara mubisanzwe bigufi muburebure, bigufi kurenza urudodo rusanzwe, kandi ntibishobora kugabanya diameter yumubiri.

Ukurikije ihame, bimwe bidasanzwe biremewe. Mbere ya 2016, ASTM A325 na ASTM A490 byari ibintu bitandukanye. Kuva icyo gihe bashyizwe mu byiciro nk'amasomo mu bisobanuro bya F3125. Ku ikubitiro, Bolt ya A325 na A490 yagombaga kugira umutwe uremereye kandi ntayindi miterere yari yemerewe. Mubyongeyeho, uburebure bwurudodo rugufi ntibushobora guhinduka.

Ariko, ukurikije ibisobanuro bishya bya F3125, uburyo ubwo aribwo bwose bwo mumutwe buremewe kandi uburebure bwurudodo burashobora guhinduka. Guhindura muburyo busanzwe bwa A325 na A490 byerekanwe mugushyiramo “S” kumurongo uhoraho kumutwe.

Irindi tandukaniro muburebure bwurudodo ni uko A325 bolts ikorwa cyane muburyo bwuzuye-bwuzuye, mugihe ari diametero enye cyangwa munsi yuburebure. Ubu bwoko bwa bolt bakunze kwita A325T. Impapuro zuzuye zuzuye ziyi A325 ntizishobora kuboneka kuri A490.

Kwipimisha

A325 ya galvanised bolts igurwa hamwe nutubuto hamwe nogeswa gukomeye birasabwa kuba ubushobozi bwo kuzunguruka. Ikizamini cyubushobozi bwo guhinduranya cyerekana ko inteko ya bolt ishoboye guteza imbere imbaraga zifatika. Kugira ngo batsinde ikizamini, inteko igomba kugera ku ntera ntoya yo kuzenguruka no kugera ku mpagarara zisabwa mbere yo gutsindwa biterwa na diameter n'uburebure bwa A325 ya bolvan. Kubera ko A490 bolts idashobora gushyirwaho imbaraga, iki kizamini ntabwo gikurikizwa.

Bolt zose za A490 zigomba gutsinda ikizamini cya magneti. Iki kizamini gikoreshwa kugirango harebwe niba nta nenge yo munsi cyangwa ibice byacitse mu byuma bya A490. Iki kizamini ntabwo gisabwa kuri A325

Umurongo w'urufatiro

Ubwanyuma, injeniyeri wawe azagaragaza icyiciro cya F3125 cyubaka ukeneye gukoresha, ariko ni ngombwa kumva itandukaniro riri hagati y amanota A325 na A490. Icyiciro cya A490 kirakomeye kuruta icyiciro cya A325, ariko imbaraga ntabwo aricyo kintu cyonyine kigena bolt. A490 bolts ntishobora gushyukwa cyangwa gushyirwaho imashini. Urwego rwa A325 ntabwo rukomeye, ariko nigiciro gito gishobora gushirwa kugirango wirinde kwangirika.
