Iibholiti ezinkulu zentloko ene-hexagonal ASTM A 325/ASTM A490

1.Zeziphi iibholithiizakhiwo ezinkulu zentloko ezine-hexagonal?

Iibholiti ezineentloko ezinkulu ze-hexagonal ziyi-fasteners ezisetyenziselwa ukudibanisa izakhiwo zetsimbi eziphezulu. Intloko yayo imile okwe-hexagonal enkulu ekwaziyo ukumelana ne-high-power tensile kunye ne-chear forces. Banokubonelela ngoqhagamshelwano olukhuselekileyo noluthembekileyo, ngoko ke lusetyenziswa ngokubanzi kwiibhulorho, izakhiwo, koololiwe, koohola bendlela, nakwezinye iiprojekthi ezinkulu.

2.Yintoni umahluko phakathiI-ASTM A325kunye ne-ASTM A490?

I-ASTM A325 kunye ne-ASTM A490 zombini zizinto eziqhelekileyo ezisemgangathweni kwiibholithi ezisetyenziswa kwizakhiwo ezinkulu zentloko ezine-hexagonal. Ziyahluka ngokwamandla ezinto eziphathekayo. I-ASTM A325 iqhele ukusetyenziselwa izakhiwo zamandla aphakathi, ngelixa i-ASTM A490 isetyenziselwa izakhiwo ezinkulu, ezithwele kakhulu.

Iibholiti ze-A325 zenziwa ikakhulu yi-TYPE1 kunye ne-TYPE3. I-TYPE1 isetyenziselwa ulwakhiwo jikelele kwaye inokuba yi-Hot-dip gavanization xa kukho imfuneko. Intsimbi ekwaziyo ukumelana nemozulu iya kusetyenziswa kunye neebholithi ze-TYPE3, eziya kuphawulwa ngokukodwa kumzobo woyilo xa kusetyenziswa iibholithi ze-TYPE3.

Amandla esixhobo se-A490 bolt aphezulu kune-A325, kodwa i-A490 bolt ayinakuba yi-Hot-dip galvanization. Iibholiti ze-A490 zahlulwe zaba ziindidi ezintathu ze-TYPE3 zodidi lwebholiti ezinentsimbi yemozulu efanayo.iibholiti A325 kunye A490zinediamitha ezisemgangathweni ezinyaweni kunye nokunyuswa kwe 1/8 yenyawo, zombini phakathi kwe 1 yonyawo kunye ne 1.5 yenyawo, kunye nobubanzi obujikeleze unyawo olu-1 olusetyenziswa kakhulu.

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

I-ASME B18.2.6-2010 ngumgangatho waseMelika ochaza iimfuno zemilinganiselo, imathiriyeli, iipropati zomatshini kunye neekhemikhali, ukuveliswa, kunye nokumakishwa kweebholithi zezakhiwo ezinkulu zentloko ezine-hexagonal.

4.Yintoni umsebenzi weebholithi zezakhiwo ezinkulu zentloko ezine-hexagonal?

Umsebenzi oyintloko weebholithi ezisetyenziswe kwizakhiwo ezinkulu zentloko ye-hexagonal kukudibanisa iindawo ezahlukeneyo zesakhiwo sensimbi, okwenza amacandelo aphelele. Ziyakwazi ukumelana namandla aphezulu kwaye zibe ne-seismic ephezulu kunye nokumelana nomoya. Ngoko ke, iibholiti zezakhiwo ezinkulu ze-hexagonal zentloko luhlobo olubalulekileyo lwe-fastener kubunjineli bokwakha.
