Iibholithi zeMetric Heavy Heavy Structural (ASTM A 325M ASTM A 490M)

Kumsebenzi wolwakhiwo othembekileyo kwiiprojekthi zolwakhiwo lwemetriki, iibholithi zolwakhiwo ze-metric ezinzima ze-hex ezidibana nemigangatho ye-ASTM A325M kunye ne-ASTM A490M. Ngoncedo lwazo oluphezulu, ukuxhathisa i-corrosion, kunye nobunjineli obuchanekileyo, ezi bholithi ziqinisekisa unxibelelwano olukhuselekileyo noluthembekileyo kwiindibano ze-metric structural.

IMfezeko yoLwakhiwo:Iibholithi ze-Metric ezinzima ze-hex zesakhiwo, ezihambelana nemigangatho ye-ASTM A325M kunye ne-ASTM A490M, zenziwe ngobunjineli ukubonelela ngentembeko yesakhiwo esikhethekileyo kwizicelo zolwakhiwo lwemetriki. Ezi bhotshi zenzelwe ukujamelana nemithwalo ephezulu kunye nokuqinisekisa ukuzinza kunye nokhuseleko lokudibanisa okubalulekileyo kwiindibano ze-metric structural.

Izinto zokomelela okuphezulu:Ziyilwe ukusuka kwi-alloys yentsimbi yokuqina okuphezulu, ezi bholithi zibonelela ngepropathi ephezulu yokuqina kunye neempawu zamandla okucheba, zizenza zilungele ukusetyenziswa kusetyenziso lwe-metric yolwakhiwo oluphantsi kwemithwalo enzima kunye namandla aguqukayo. Ulwakhiwo lwabo olomeleleyo lunyusa ukuqina kunye nokuthembeka kweendibano zemetric zolwakhiwo.

Ukuxhathisa ukonakala:I-Metric heavy hex iibholithi zolwakhiwo ziyafumaneka ezineengubo ezikwaziyo ukumelana nomhlwa kunye nezixhobo zokumelana neemeko ezirhabaxa zokusingqongileyo, kubandakanya nokuvezwa kukufuma, iikhemikhali, kunye nezinto zangaphandle. Oku kuxhathisa kwe-corrosion kuqinisekisa ukusebenza kwexesha elide kunye nokunciphisa umngcipheko wemiba yesakhiwo ngenxa yokubola.

Ubunjineli obuchanekileyo:Ezi bholithi zijongwa ngokungqongqo ukuze kuqinisekiswe ukunyamezelwa okuchanekileyo kunye nokuhambelana namalungu e-metric structural. Oku kuchaneka komda kuququzelela ukulungelelaniswa okufanelekileyo kunye nokulungelelaniswa ngexesha lokudityaniswa, igalelo kumgangatho uwonke kunye nokuthembeka kweeassembly ze-metric structural.

Isiqinisekiso kunye noVavanyo:Iibholithi zeMetric enzima zehex zenziwa kwiinkqubo zovavanyo olungqongqo zokuqinisekisa iipropathi zabo zoomatshini, ukwakheka kweekhemikhali, kunye nokuthotyelwa kwe-ASTM A325M kunye ne-ASTM A490M. Isatifikethi siqinisekisa ukuba iibholithi ziyahlangabezana nemigangatho yoshishino kunye neemfuneko zokusebenza kwizicelo ze-metric structural.

Izikhokelo zokuFakela:Ubuchule bofakelo obufanelekileyo, kubandakanywa iinkqubo ezichanekileyo zokuqinisa kunye nokwenza ngathi ibholithi, zibalulekile ekwandiseni ukusebenza kweebholithi ze-metric ezinzima ze-hex zesakhiwo. Ukulandela iingcebiso zomenzi kunye nezona ndlela zilungileyo zoshishino ziqinisekisa uqhagamshelo olukhuselekileyo noluthembekileyo kwiindibano zolwakhiwo lwemetric.

Uthethwano neNkxaso:Ukubonisana neenjineli zolwakhiwo kunye neengcaphephe zoqinisekiso kuyacetyiswa xa kukhethwa iibholithi ze-metric ezinzima ze-hex zesakhiwo kwiiprojekthi zokwakha. Banokubonelela ngengqiqo ebalulekileyo kunye noncedo ekukhetheni uhlobo olufanelekileyo lwebholithi, ubungakanani, kunye nebakala lokuhlangabezana neemfuno ezithile zeprojekthi kunye nokuqinisekisa imfezeko yesakhiwo.

Usetyenziso Olubalulekileyo:Iibholithi zolwakhiwo olunzima lwe-metric zidlala indima ebalulekileyo kwizicelo ezahlukeneyo zolwakhiwo lwemetric, kubandakanya izakhiwo, iibhulorho, iinqaba kunye neeprojekthi zeziseko zophuhliso. Ukusebenza kwabo okuthembekileyo kunye nokuthobela imigangatho yoshishino inegalelo kukhuseleko, uzinzo, kunye nokomelela kwezakhiwo zemetric ezibalulekileyo.
