1. Install Retaining Rings:

Next, place the retaining rings. These are essential as they hold the fabric joint in place and distribute the pressure evenly across the surface. Start by loosely fitting the rings to allow some adjustment before final tightening. Check that the gap between the joint and the ring is uniform.

1. Bolt Tightening Sequence:

Begin tightening the bolts in a cross pattern to ensure even pressure distribution across the joint. Don't tighten one bolt completely before starting the next; gradually tighten them in several passes to avoid fabric distortion or tearing.

Adjusting for Temperature Variations

You'll need to adjust the fabric expansion joint to account for temperature variations that can affect its performance. Remember, the material properties of the joint components like fabric, flanges, and sealing elements will change depending on the heat or cold they're exposed to.

Firstly, consider the thermal expansion or contraction of the joint. The fabric may expand in hot environments and contract when it's cold. To manage this, make sure there's enough flexibility built into the installation design. This might mean allowing extra slack in the fabric during cooler installation conditions.

You'll also want to check the manufacturer's specifications for temperature ranges and adjust your setup accordingly. Different materials react differently to temperature changes. For instance, a fiberglass fabric joint might handle heat better than a synthetic rubber one.

Additionally, it's important to think about the ambient temperature during installation. Installing the joint in extremely cold or hot conditions can initially stress the material. Aim for a moderate temperature if possible, or make sure the material is conditioned to handle extreme temperatures from the start.
