As you have mentioned Mr Raj, I am asking about the 20mm rod which we weld on
the plate (casted on the top of sleeper) or rack. As you have mentioned about
the frictional force - Frictional force is nothing but the multiplication of
frictional coefficient of metal and the reaction which is getting from the fixed
body. so, i don't think that there will be any measure difference in the
frictional force (resistance which will act on pipe while expansion of pipe
metal takes place) when the contact is either point contact, line contact or
surface contact.
One of the reasons which i heard about the provision of Rod is to reduce
corrossion. during rainy season, rain water may get collected on the top of
sleeper plate - which can corrode the pipe also. To avoid this collecion of
water between bottom of pipe and top of sleeper, rod is provided.
Please suggest whether it is true or any other reason is there.
regards,
rakesh
