ASTM A537 Kirasi 1,2,3 Boiler uye Pressure mudziyo simbi ndiro

Iyo ASTM A537 yakatarwa ndiyo Yakajairwa Kutsanangurwa kwePressure Vessel Plates, Heat-Treated, Carbon-Manganese-Silicon Steel inoshandiswa mukushandiswa kwefusion welded pressure midziyo uye zvimiro. Mashandisirwo akajairika midziyo yekumanikidza yakagadzirirwa ine mwero uye yakaderera-tembiricha sevhisi inoda yakanakisa notch kuomarara pamwe neAPI 650 uye API 620 ekuchengetedza matangi. Kirasi 1 zvinhu zvinowanikwa seZvakajairwa uye Kirasi 2 inowanikwa seYakadzimirwa & Kupisa mahwendefa.
