Which step follows the centering of the sleeve during split sleeve installation?

After the sleeve has been properly centered during the installation process, the next crucial step is to tighten the bolts to the manufacturer's specifications. This step is essential because it ensures that the sleeve is secured appropriately, creating a reliable and safe connection in the distribution pipe system. Correctly tightening the bolts also helps maintain the integrity of the sleeve under pressure, preventing leaks and potential failure of the repair.

Following the manufacturer's specifications is critical as it provides guidance on the torque settings required for the specific type of sleeve being installed. This ensures that the bolts are neither over-tightened, which could damage the pipe or the sleeve, nor under-tightened, which could lead to insufficient sealing and leak issues. Proper bolt tightening ultimately contributes to the longevity and effectiveness of the repair.

Other steps mentioned in the choices, such as performing a soap test or lubricating the gaskets, while important in their own right, come after ensuring that the sleeve is securely fastened with the correct bolt tension. These processes help to finalize the repair and check for any installation issues but are not the immediate next step following the centering of the sleeve.
