Supporting Steam Pipes

<please guide what is used on exhaust pipes of diesel alternator which are horizontal>

On Rollers : supported from below or from top(Hanger)

<can be rigidly supported or not>

Better NOT

<expansion bellow on inlet and outlet of exhaust silencer and why>

Needed- to minimize shock from/to Exhaust manifold

<silencer is rigidly supported>

Silencer can be on rollers too.

Steel pipe as used for handling the movement of fluid and gases are hung horizontally in a cradle type hanger.

Exhausts pipe hangers there are many different types. The universal one is a metal perforated strap with a one hole anchor connected together with a piece of high temperature rubber or leather. Rubber or leather allows for expansion and contraction. If rigidly attached to the vehicle vibration would wear through the pipe.

The exhaust silencer(muffler) in you case is large and they don't want it bouncing around. Have seen them supported with flexible straps also.

Bellows are to protect the devices from vibrations that would damage the connections.

Before applying any idea, please provide the drawings of piping isometric with all details related to pipe material, diam., thk., pressure, temp., existing supports, ..... etc. Such a stress analysis must be carried out to discover the portion of excessive stresses and the optimum locations of pipe supports and hangers.
