Hi,

I want to combine 2 liquid streams(pipes) at different temperatures(say 60C and 130 C) into one stream,
do I have to use the static mixer ? Or Can I directly join them together (in this case,will it cause water hammer?)

Thanks !

Water hammer is caused by an abrupt change in momentum. ie the sudden opening or closing of a valve.
The temperatures of the two liquid streams will not cause any water hammer.
What you should look at are the pressures of your two streams to ensure that the hydraulics are good, but I would not expect any "water hammer" issues if you just T the two streams together.
A static mixer will speed up mixing of the two streams, however sufficient turbulence in the pipe will mix the fluids as well.
