Bahut fast poochta hai ye surveyor
Boiler corrosion- caustic embritlement, pitting corrosion, acidic corrosion, galvanic corrosion, hydrogen corrosion etc.
Graphatization- Galvanic corrosion between iron and carbon present in graphite form in cast iron, iron get corroded having low electrode potential.
Oxygen is removed by maintaining feed water temp around 80-90 degree and adding chemicals like oxygen scavenger (hydrazine), sodium sulphite.
Oil foaming in refer is due to moisture and air.
Exhausting- pulse type and constant pr. type
Nozzle ring converts pr energy into kinetic energy and directs exhaust gas on blades.
AE exhaust gas has fluctuating and not sufficient heat energy for our required steam.

1. 4cm side and 1.5cm thick square plate is given, how to make 8mm thread?
2. If both bearings of centrifugal pump worn out, how to remove and fit new one.
3. How to adjust tappet clearance (and for finding injection tdc, he didn't agree to any other method, wanted to listen just one method by checking follower of fuel pump on peak of cam profile)
4. How to measure main engine bottom end bearing clearance?
5.1000running hours routine of auxiliary engine.
Decider: Listened overheating of connecting rod(which is checked after 1000running hours)... and then asked how to check ovality of connecting rod and calculation as per manual.

1. Cpp from bridge not working .... Your actions ..with diagram ..step by step illustrate in diagram .... Cross questions ... Unbeatable..
2. Piston crown and skirt how they are connected. ... Again with diagram ...also what are the tests will you on the connections..
3.Boiler emitting black smoke... What are the reason ... Draw ..the how the secondary air will enter and reaches the furnace ..
4.how the counter wait attached with the crankshaft ... Please draw the diagram ..
5.there is zig zag pipe ... U have fabricate with appropriate length ....
Got ...2 of the are nearly correct
Internal meena ( may be ).
Working rotocap (correct ,)
Welding types with explanation ( correct)
Then external ask what is gauging in termes of welding ( no idea) ...
Better luck next time.........
