Answer Posted / krishnamurthy
In water tube boilers - there is no fusible plug and there
is a safety valve. In fire tube boilers it may be there and
material will be lead (less melting point than steel)
Boiler pressure parts shall confirm upto 420 deg c in
carbon steel confirming to ASME A106 Gr. B, for
applications more than 420 to 480 Deg C it shall be ASME
A335 Gr.P1 or P11 and more than than it will be P22, P91
etc. structures shall confirm to IS 2062 Grade B
