ASTM A53 Dhexeeya Steel Pipe | Xiriir & La xiriiraya Industrial Solutions

Dhulka A53 carbon steel ee ASTM waxaa la sameyn karaa mid ka dib marka ah loo isticmaalaya in ay ugu yarid ama xaaladooda ah ee dhammaan, ku jira ERW (Type S) iyo furnace butt welded (Type F) dhulka ah ee carbon steel. Marka ah waxaad ku yimid sano hore: Grade A (dhexeeynta 248 MPa) iyo Grade B (dhexeeynta 345 MPa), oo Grade B waxaa lagu yeerayaa si toos ah in ay ku samayn doontaa dhexeeyaada ku caddeed ah. Dhulka A53 ASTM waxaa ku jiro diameter carruurta ah ee ku raaco 1/8 inch taal 26 inches, iyo qoraalka kale ee ku jiro Schedule 10 taal Schedule 160, ku jiraan loo isticmaalo karo dadkii ee ugu yarid ama caafimaadka ah. Proseska ERW (Type S) wuxuu ku joogto dhulka ah ee lacagaha dheeraad ah, oo ahayd magaca fluid flow, iyo proseska furnace butt welded (Type F) wuxuu u baahantoo dhulka ah ee diameter ku jabeen ama qoraalka guriga ah. Xusuusooyinka ah waxaa ku jirin dhexeeynta weynaanta ah (elongation ≥25% ee Grade A), iyo weldability, iyo ugaarinta ee kor sheegidda ah ee ku jira moderate corrosion coating. Dhulka A53 ASTM waxaa la sameyn karaa marka ay ugu yarid kartaa ee dhaqanka ah ee carruurtanka ah, iyo pipeline ee gaar ah ee natural gas (low pressure), iyo isticmaalada caafimaadka ah kama ah fence posts, iyo frames ee machine. Isticmaalada lacagaha waxaa ku jirin black (uncoated), galvanized (ASTM A120 ee Type F, A123 ee Type S), iyo painted, oo dhulka galvanized waxaa lagu yeerayaa si toos ah in ay ku saabsan doontaa ee environmental humidity. Xaqiijinta qaabka ASTM A53 waxaa la sameyn karaa testing hydrostatic ee 1.5x ee working pressure ee la sameyn karaa, iyo chemical analysis ee ku jiraan carbon content ≤0.30% (Grade B), iyo sulfur/phosphorus ≤0.05% ee weldability. Dhibaatooyinka ah waxaa la sameyn karaa marka ay ugu yarid kartaa ee projects internationale ah tusaale ah ee global recognition ee standardka ASTM, iyo compatibility ee ku jiraan range ee wide fittings iyo joining methods (threaded, welded, grooved). Waxaa la sameyn karaa suppliers compliance certificates, iyo mill test reports ee ku jiraan dimensions, iyo properties ee materialka, iyo results ee testing, iyo waxaan idinku sameyn kartaa services ee value added ah kama ah cutting to length, iyo beveling ee ku saabsan doontaa ee construction sites.
