I-ASTM A53 ichaza iimfuno zemibhobho yentsimbi engenamthungo/ewelding emnyama kunye neshushu-diphu ukuze isetyenziswe ngokubanzi. Insimbi edweliswe kumgangatho kufuneka iqhutywe kwisithando somlilo esivulekileyo, i-oksijini ye-alkaline okanye isithando sombane, kwaye kufuneka ibe nezi mfuno zilandelayo zamachiza: i-carbon, i-manganese, i-phosphorus, isulfure, ithusi, i-nickel, i-chromium, i-molybdenum kunye ne-vanadium. Umbhobho kufuneka ungenamthungo okanye udityaniswe. Uvavanyo lwe-tensile, ukugoba kunye nokulinganisa kufuneka lwenziwe ukuze kuqinisekiswe ukuba kufuneka kuhambelane neempawu eziqhelekileyo zoomatshini. Uvavanyo loxinzelelo lwe-Hydrostatic luya kwenziwa, kwaye akukho kuvuza nge-weld okanye umzimba wombhobho. Uvavanyo lombane olungonakaliyo kufuneka lwenziwe ukuze kuqinisekiswe ukuba umthamo opheleleyo wombhobho kufuneka uhlangabezane nomgangatho. Ukuba kubonwa kuyimfuneko ukuqinisekisa ukuba umbhobho uhlangabezana neemfuno ezichaziweyo, umthengi unelungelo lokuqhuba naluphi na uhlolo kunye neemvavanyo ezichazwe kule nkcazo.
I-ASTM A 53 ifanelekile kwiinkqubo zemibhobho yoxinzelelo, iipayipi zemibhobho kunye nemibhobho yenjongo jikelele kwiqondo lokushisa lama-350 degrees. Phakathi kwabo, ibakala lensimbi ye-Gr.B iyona nto isetyenziswa ngokuqhelekileyo, kunye namandla ayo obunzima ≥ 415 (MPa) kunye namandla okuvelisa ≥ 240 (MPa).
Isicelo
Isetyenziswa ikakhulu kumandla kunye noxinzelelo lwamalungu, kunye nenjongo eqhelekileyo yomphunga, amanzi, igesi kunye nemibhobho yomoya.
