SA 178 Gr A Boiler Tubes

SA 178 Gr A boiler raj muaj qhov kub thiab txias tsis kam thiab lub zog ua haujlwm siab, thiab tuaj yeem tiv taus qhov kub thiab txias thiab ua haujlwm siab.

Tom ntej: ASTM A178 Boiler Tube
ASTM 178 Resistance Welded Carbon thiab Carbon Manganese Steel Boiler Tubes thiab Superheater Tubes
ASTM A178 boiler raj yog paub txog lawv cov kev tiv thaiv corrosion thiab kub hloov. GNEE muab ASTM A 178 Qib A & C & D boiler raj rau ntau yam kev siv hauv kev lag luam.

Dab tsi yog Lub Cev Khoom Ntawm ASME SA178 Carbon Steel Tubes?

SA 178 carbon manganese ERW yeeb nkab muaj lub zog tensile xws li 47 ksi (325 MPa) txog 70 ksi (485 MPa). ASME SA178 welded steel boiler raj muaj lub zog tawm los ntawm 26 ksi (180 MPa) thiab 40 ksi (275 MPa).
Lub elongation ntawm A178 yeeb nkab yog nruab nrab ntawm 30% thiab 35%. Cov khoom no sib txawv ntawm ntau qib SA 178 raj. Cov yam ntxwv tseem ceeb yog superior hluav taws xob tsis kam thiab muaj zog tiv thaiv corrosion. Lub hardness ntawm cov kav dej no nyob ntawm 77 txog 79 HRB.
