Iindaba - Ukubaluleka kweePleti zeNsimbi ze-ASTM A283 kwiiprojekthi zokwakha eMelika

Ipleyiti yentsimbi ye-ASTM A283 yintsimbi eyakhiwe ngekhabhoni engaphantsi kwe-alloy esetyenziswa kakhulu kulo lonke elaseMelika ngenxaukusebenza okuzinzileyo koomatshini, ukusebenza kakuhle kweendleko, kunye nokulula kokwenziwaUkususela kwizakhiwo zorhwebo kunye nezakhiwo zoshishino ukuya kwiiprojekthi ezinkulu zeziseko zophuhliso, iipleyiti zentsimbi ze-A283 zibonelelainkxaso yesakhiwo ethembekileyo.

Isishwankathelo sePlate yeNsimbi ye-ASTM A283

Ipleyiti yentsimbi ye-ASTM A283yenzelwe izakhiwo zokwakha nezobunjineli ezithwalaimithwalo ephakathiYahlulwe yabaAmabanga A, B, C, kunye no-D, nganye ineempawu zeekhemikhali nezoomatshini ezahlukeneyo ukuhlangabezana neemfuno ezahlukeneyo zobunjineli.

Ezi mpawu ziqinisekisa ukuba iipleyiti zentsimbi ze-ASTM A283 ziyakwazi ukusingathazombini imithwalo engashukumiyo neyamandla, kuquka amandla omoya kunye nokusingqongileyo.

Iingenelo zokusebenza

Amandla athembekileyo: Iqinisekisa ukhuseleko phantsi kwemithwalo enzima yesakhiwo.

Ukudityaniswa kakuhle: Ifanelekile kwizakhiwo ezinkulu zentsimbi kunye nokuwelda kwindawo.

Ukwenziwa kweekhemikhali ezifanayo: Iqinisekisa ukuqina kwexesha elide kunye nokuthembeka kwesakhiwo.

Ezi mpawu zenza iipleyiti zentsimbi ze-A283 zibe lukhetho olukhethwayo kwiiprojekthi zokwakha ezingabizi kakhulu nezikhuselekileyo.

Izicelo eMelika

Ipleyiti yentsimbi ye-ASTM A283 isetyenziswa kakhulu kwezi:

Izibonelelo zoshishino kunye neendawo zokugcina impahla: Izakhelo zophahla ezinkulu kunye neenkxaso zodonga

Izakhiwo zorhweboIinqaba zeeofisi, iindawo zokuthenga, izakhiwo ezinemigangatho emininzi

Iiprojekthi zeziseko zophuhliso: Izixhaso zebhulorho, iindonga ezigcina amanzi, iingxangxasi ezikhuselayo

Kwiindawo ezisengozini yeentlekele zemvelo ezifana nezikhukula kunye neenyikima,Ipleyiti yentsimbi ye-A283inika ukuqina okuphuculweyo kunye nokhuseleko lwesakhiwo.

Iingenelo zeendleko kunye nokwakha

Isebenza kakuhle emalini: Ixabiso liphakathi kwaye ifumaneka ngokubanzi eMntla naseMzantsi Melika.

Ukwenziwa okulula: Ukudityaniswa kakuhle kunye nokukwazi ukwakheka kakuhle kwesakhiwo esikhulu sentsimbi kunye nokudityaniswa kwindawo.

Ulwakhiwo olusebenzayo: Inciphisa ixesha leprojekthi kunye neendleko zizonke ngelixa igcina ulwakhiwo lusemgangathweni.

Isiphelo

Ngeukwakheka kweekhemikhali okuzinzileyo, isivuno esiphakathi kunye namandla okutsalwa, ukudityaniswa okuhle kakhulu, kunye neenzuzo zeendleko, Ipleyiti yentsimbi ye-ASTM A283 ibaluleke kakhulu kwimarike yokwakha yaseMelika. Njengoko imfuno yezakhiwo zoshishino nezorhwebo ikhula, ipleyiti yentsimbi ye-A283 iya kuqhubeka nokudlala indima enkulu.indima ebalulekileyo kwiiprojekthi zokwakha ezikhuselekileyo, ezihlala ixesha elide, nezisebenzayo.
