Types of Power Hammers [Explained in Detail] Images & PDF
3. Steam or Air Power Hammer. A steam-power hammer can be performed by either steam or compressed air. It includes a moving ram, rod, and piston, a lifting tool, a double-acting high-pressure steam cylinder, housing or frame, and anvil. In these types of forging power hammers, initially, steam is entering the bottom of the cylinder and the ...
Mechanical response of buried and covered pipes under water hammer
5.5.1. Water hammer wave speed in a covered/buried pipe. For a pipe within a surrounding soil continuum, the radial displacement of pipe wall is given by w p = R ε φ = ( 1 − ν 2) R 2 ( P − P o) / E h, where P is the pressure acting on the inside surface of the pipe and P o is the pressure on the outside surface of pipe.

Water Hammer
Water Hammer. When a liquid flowing through a long pipe is suddenly brought to rest by closing the valve at the end of a pipe, then a pressure wave of high intensity is produced behind the valve. This pressure wave of high intensity has the effect of hammering action on the walls of the pipe. This phenomenon is known as water hammer or hammer blow.
