Tightening a Clamp Using Bolt Tensioner

Define the clamp. Mfg. and Part number.

It is a Riser clamp. 6 pcs of bolts on each clamp

I'm afraid I don't understand the problem.

You want them tight, that's about it.

Here's a chart for you:

Not easily until you have more numbers to work with.

Not my area of expertise but does this help?

I looked at them for a study of A325 bolts once, but there is insufficient thread on those bolts.

This is about the least demanding application a fastener could see.

The complete lack of understanding of the OP regarding the application leads me to beleive that much is unknown about mechanical fasteners and their use.

I think the OP wants to use a hydraulic tensioner. They tension the bolt from the stub end, nut on, then roll the nut to the snug position and then remove the external tension, tightening the grip. For this operation, he must know what tension to apply to the bolt.

See my #5, above.

my area of expertise and there is not enough info.

m22 really shouldn't need tensioned, should be torqued with a hydraulic torque wrench. And usually on a clamp you will need a special bridge, it's not just a normal flange.

Riser Clamp, who makes it and what size is it. The manufacturer will have a recommended figure for tightening, it might be a torque figure, it might be a residual bolt stress or it might be a clamping load?

M22 Bolt, what material? are the bolts overlength by at least 2 bolt diameters?

Pump pressure? Whose tensioners and what size are you using?

Is this production? Then you need to get more information. Drilling? Just get the flogging spanners out and a big hammer!
