Steam hammering:-If a steam pipe-line is to be charged,
initially all the condensate in the line is to be drained
out. If draining is improper & if some condensate is left
in the line,then at the time of steam charging in line may
cause hammering.This is steam hammering.This is because of
sudden drop in pr. of steam as it comes in contact of
condensate.
Water hammering:-Pr. surge in water occuring because of
sudden drop in velocity of water flowing through a pipe
(mainly because of sudden closing of valves) causes
hammering effect in pipe-line.
Its intensity depends on rate of drop of velocity of
water,dia. of pipe&length of pipe.

Answer / subhransh shekhar
Initially,the steam line is in ambient temp condition.when it is suddenly charged then some portion of the line remains cool in comparison to the other.due to nonuniform heating.in the cooler area condensate ball foRmed and vacuum is created.and all the molecules rushed towards that particular area.and hammering created. water hammer-this is caused due to the impact caused by suddenly closing and opening the valve in a flowing fluid line.

Answer / vimal.v.p
Consider a pipe line with a regulating vave, carrying water
from a reservoir to some sump...
Initially the valve is imagined to be fully
opened and water will be freely flowing. Suppose we shut the
valve suddenly, The Water coming the upstream will be
subjected to impact the Valve shutter , causing severe boost
in water pressure and produces vibrations in
pipeline...,known as water hammer...
Steam Hammer may be attributed to the similar
effect caused by working steam

Answer / m
Actually the main difference between steam hammering and
water hammering is, In a steam pipe if there is some water
accumulation it is carried over by the high pressure and
high temperature steam and it creates hammering this is
known as water hammering in steam pipes
Similarly in a water pipe is steam enters it will create
some sound this is known as steam hammering.
