Izakhiwo ezinkulu zekhanda eliyi-hexagonal amabhawodi we-ASTM A 325/ASTM A 490

1.Ayini amabhawodiizakhiwo ezinkulu zekhanda ezine-hexagonal?

Amabhawudo anamakhanda amakhulu anezinhlangothi eziyisithupha ayizibophelelo ezisetshenziselwa ukuxhuma izakhiwo zensimbi ezinamandla aphezulu. Ikhanda layo linomumo omkhulu onama-hexagonal elikwazi ukumelana namandla amakhulu okushuba kanye namandla okugunda. Anganikeza ukuxhumana okuphephile nokuthembekile, ngakho asetshenziswa kakhulu kumabhuloho, izakhiwo, imizila yezitimela, imigwaqo emikhulu, namanye amaphrojekthi amakhulu.

2.Uyini umehluko phakathiI-ASTM A325kanye ne-ASTM A490?

I-ASTM A325 ne-ASTM A490 zombili yizicaciso ezijwayelekile zamabhawodi asetshenziswa ezakhiweni ezinkulu zekhanda ezinezinhlangothi ezine. Ayahluka ngamandla ezinto ezibonakalayo. I-ASTM A325 ijwayele ukusetshenziselwa izakhiwo zamandla amaphakathi, kuyilapho i-ASTM A490 isetshenziselwa izakhiwo ezinkulu, ezilayishwe kakhulu.

Amabhawodi e-A325 ikakhulukazi akhiwe yi-TYPE1 ne-TYPE3. I-TYPE1 isetshenziselwa isakhiwo esijwayelekile futhi ingaba i-Hot-dip galvanization uma kudingeka. Insimbi engamelana nesimo sezulu izosetshenziswa kanye namabhawodi e-TYPE3, azomakwa ngokukhethekile emdwebeni womklamo lapho kusetshenziswa amabhawudi angu-TYPE3.

Amandla ezinto ze-A490 bolt angaphezulu kwe-A325, kodwa i-A490 bolt ayikwazi ukuba i-Hot-dip galvanization. Amabhawodi e-A490 ahlukaniswe abe izinhlobo ezintathu zamabhawodi ohlobo lwe-TYPE3 anensimbi efanayo yesimo sezulu.I-A325 kanye ne-A490 boltsabe nobubanzi obujwayelekile ezinyaweni kanye nokukhula okungamafidi angu-1/8, kokubili phakathi kwefidi elingu-1 no-1.5, nobubanzi obuzungeze unyawo olu-1 busetshenziswa kakhulu.

3.Iyini i-ASME B18.2.6-2010?

I-ASME B18.2.6-2010 iyindinganiso yaseMelika ecacisa izimfuneko zobukhulu, izinto zokwakha, izakhiwo zemishini namakhemikhali, ukukhiqizwa, nokumaka amabhawodi ezakhiwo ezinkulu zekhanda ezinezinhlangothi ezine.

4.Uyini umsebenzi wamabhawodi wezakhiwo ezinkulu zekhanda ezinezinhlangothi ezine?

Umsebenzi oyinhloko wama-bolts asetshenziswa ezakhiweni ezinkulu zekhanda le-hexagonal ukuxhuma izingxenye ezahlukene zesakhiwo sensimbi, okwenza izingxenye ziphelele. Bangakwazi ukumelana namandla amakhulu futhi babe nokuzamazama komhlaba okuphezulu nokuphikiswa komoya. Ngakho-ke, ama-bolts wezakhiwo ezinkulu zekhanda eline-hexagonal awuhlobo olubalulekile lwe-fastener kubunjiniyela bokwakha.
