Iibholiti zeHex eziManzi [Itheyibhile 3] (ASTM A307)

Ukuqina okuqinileyo nokuthembekileyo kwimisebenzi enzima, themba iibholiti ze-hex ezinzima ezivela kwi-ASTM A307. Ngemathiriyeli yazo ekumgangatho ophezulu, ukwenziwa okuchanekileyo, kunye neengubo ezikwaziyo ukumelana nomhlwa, ezi bholithi zibonelela ngokusebenza okugqwesileyo kunye nokuqina.

Umzekelo:ASME B 18.2.1

Izisombululo zokuQinisa okuQinisayo:Iibholiti ezinzima zehex, njengoko zibonakaliswe kwiThebhile 3 (ASTM A307), zenziwe ngobunjineli ukubonelela ngokuqiniswa okuqinileyo nokuthembekileyo kwizicelo ezahlukeneyo. Ngolwakhiwo lwabo olomeleleyo kunye nobukhulu bentloko enkulu, ezi bholithi zinika amandla aphezulu kunye nokuqina, zizenze zilungele iindibano zolwakhiwo olunzima kunye noomatshini.

Izixhobo zoMgangatho oPhezulu:Yenziwe ukusuka kwintsimbi ephezulu yekhabhoni, i-hex bolts enzima evela kwi-ASTM A307 ibambelela kwimigangatho engqongqo yobulunga, iqinisekisa ukusebenza ngokugqibeleleyo kunye nokuphila ixesha elide. Iimpawu zabo zemathiriyeli ezikhethekileyo zibenza baxhathise ukunxitywa, ukuguqulwa, kunye noxinzelelo lomatshini, nakwindawo ezingqongileyo ezinzima.

Uveliso oluchanekileyo:I-hex bolt nganye enzima ingena kwiinkqubo zokwenziwa ezichanekileyo ukuhlangabezana nokuchaneka kobukhulu kunye neemfuno ezingqongqo zokunyamezelana. Le ngqalelo kwiinkcukacha iqinisekisa umgangatho ohambelanayo kunye nokulungelelaniswa okufanelekileyo, okuyimfuneko ekuqiniseni okukhuselekileyo nokuzinzileyo kwizicelo ezibalulekileyo.

Ii-Aplikeshini eziNyezo:Ngoluhlu olubanzi lweesayizi zentambo, ubude, kunye nobubanzi obukhoyo, iibholiti ze-hex ezinzima zizibophelelo eziguquguqukayo ezifanelekileyo kumashishini ahlukeneyo kunye nokusetyenziswa. Nokuba zisetyenziswa kulwakhiwo, kwiziseko ezingundoqo, okanye koomatshini, ezi bholithi zinika amandla okubamba athembekileyo kunye nemfezeko yolwakhiwo.

Ukuxhathisa ukonakala:Ukomeleza ukuqina kunye nobomi obude, iibholiti ezinzima ze-hex zinokugqunywa ngezinto ezikwaziyo ukumelana nomhlwa ezifana ne-zinc plating okanye i-galvanization yediphu eshushu. Ezi zambatho zibonelela ngokukhusela ngokufanelekileyo kwi-rust and corrosion, ukwandisa ubomi benkonzo yeebholiti kunye nezakhiwo ezixhasayo.

Ukusebenza okuqinisekisiweyo:Iibholiti ezinzima zehex ezihambelana ne-ASTM A307 zivavanywa ngokuqatha kunye nesiqinisekiso sokuqinisekisa ukuthotyelwa kwemigangatho yoshishino. Ngokukhetha iibholiti eziqinisekisiweyo, abasebenzisi banokuzithemba ekusebenzeni kwabo kunye nokuthembeka, nakwiindawo ezifunayo kunye noxinzelelo oluphezulu.

Uthethwano lweNgcali:Xa ukhetha iibholiti ezinzima ze-hex kwizicelo ezithile, kuyacetyiswa ukuba udibane neengcali zokuzila ezinokunika isikhokelo ekukhetheni ubungakanani obufanelekileyo bebholithi, ibakala, kunye nokwaleka ukuze usebenze ngokugqibeleleyo kunye nobomi obude.
