Iyiphi impahla eyenziwe nge-ASTM A516 Gr.70?

I-ASTM A516 Gr.70 iyinsimbi ye-carbon steel. I-Carbon steel iyikilasi lezinto zensimbi eziqukethe ikhabhoni njengengxenye eyinhloko ye-alloying, imvamisa inokushisela okuhle ngakho-ke ivamise ukufanelekela ukwenziwa okushiselwe.
I-ASTM A516 Gr.70 inokuqukethwe kwekhabhoni emaphakathi okuyenza yenze kahle kuzo zombili izimo zokushisa eziphakeme neziphansi. Lesi sici sivame ukusetshenziswa ekwakhiweni kwemikhumbi yokucindezela, ama-boilers, abashintshi bokushisa nezinye izingxenye ezidingekayo ukuze zimelane nokucindezela okukhulu kanye nezindawo zokushisa eziphakeme noma eziphansi.

I-ASTM A516 Gr.70 iwukucaciswa okujwayelekile kokuchaza izakhiwo zezinto ezibonakalayo kanye nezimfuneko zempahla eziwumshini zamapuleti ensimbi okucindezela okuphansi nokushisa okuphezulu. Lokhu kucaciswa kwasungulwa yi-American Society for Testing and Materials (ASTM) futhi isetshenziswa kabanzi ezinhlelweni ezihlukene zezimboni, ikakhulukazi emkhakheni kawoyela, igesi, amakhemikhali, amandla kagesi, namandla enuzi.

Izinto ezibonakalayo:

I-ASTM A516 Gr.70 iyinsimbi ye-carbon ene-weldability enhle. Isetshenziswa kakhulu ekwenzeni imikhumbi yomfutho wokushisa ophezulu kanye nephansi yokugcina amagesi noma uketshezi.

Ukuziphatha kwemishini:

Izidingo zokusebenza kwemishini zihlanganisa amandla aqinile, amandla esivuno, nobude, phakathi kokunye. I-ASTM A516 Gr.70 ivamise ukuba namandla aphezulu uma kuqhathaniswa namandla esivuno, okuyenza ifanelekele izinhlelo zokusebenza zengcindezi ephezulu.

Ibanga lokushisa:

Ingasebenza ezimweni zokushisa eziphansi neziphezulu, ngakho-ke ifaneleka ezinhlobonhlobo zezicelo ezinezidingo ezahlukene zokushisa.

Ukucaciswa okujwayelekile:

Ukukhiqizwa nokuhlolwa kwe-ASTM A516 Gr.70 kulandela izinga le-ASTM A516/A516M, elicacisa ukwakheka kwamakhemikhali kwezinto zokwakha, izindlela zokuhlola ukusebenza kwemishini, kanye nezidingo zokuqina, izivivinyo zomthelela, njll.

Izinkambu zohlelo lokusebenza:

I-ASTM A516 Gr.70 ivamise ukusetshenziswa ekwenziweni kwezingxenye zamabhayela, imikhumbi yokucindezela, izishintshisi zokushisa, amapayipi, nezinye izinhlelo ezinomfutho ophezulu. Lezi zinhlelo zokusebenza zidinga izinto ezingakwazi ukumelana nokucindezela okuphezulu kanye nezindawo zokushisa okuphezulu ngenkathi zigcina ukuthembeka nokuphepha kwezinto.

Kafushane, i-ASTM A516 Gr.70 iyinto evame ukusetshenziswa kakhulu yomkhumbi ocindezelayo enezakhiwo ezinhle zemishini kanye nezinga lokushisa eliphezulu nezici zokumelana nezinga lokushisa eliphansi, futhi ifanele ukusetshenziswa emikhakheni ehlukahlukene yezimboni. Lapho isetshenziswa, izindinganiso ezifanele zokukhiqiza nokufaka kufanele zilandelwe ukuze kuqinisekiswe ukuthi ukuphepha nokusebenza kwemikhumbi yokucindezela kuyahlangabezana nezidingo.
