Tensile strength tie rods
I am wondering, as typically steel tie rods are used to clamp the stacks together, what forces are being applied to these steel tie rods? What is the tensile strength required?

That depends on the dimensions, liquid/gas, pressure and the type of the cylinder. Do you have more specifics?

Hi Christiaan, different stacks have different compression levels depending on the type of compression system, the materials used, number of cells in the stack, type of application, and stack requirements (e.g. performance, shock and vibration, etc.).
A typical range of stack compression forces is 18 kN – 42 kN (but some special designs may be outside this range – a stationary power application may be <18 kN and a rugged application may be >42 kN). So the tie rods, or straps, used to hold the stack together must withstand this stack compression force (depending on design, may have 4 to 8 tie rods or straps per stack).
Kind regards,
Roger
