Which fitting is known for its wrap-around design preventing movement on the pipe?

The service saddle is recognized for its wrap-around design, which is crucial in preventing movement on the pipe. This design allows the saddle to securely fit around the pipe, effectively distributing the load and adhering to the pipe's surface, which is particularly beneficial in applications where stability is necessary. The wrap-around feature minimizes the risk of leaks or displacements that could occur if the fitting allowed for any movement. This secure connection makes service saddles an excellent choice for tapping into existing pipelines without compromising their integrity.

In contrast, other fittings, while useful in specific scenarios, do not feature this wrap-around design. Repair clamps often provide a straightforward method to secure damaged sections of a pipe but do not offer the same level of stability. Bolted couplings are effective for connecting different sections of pipe but lack the unique design that prevents movement on the pipe as service saddles do. Split sleeves serve a different purpose, typically for repairs rather than for stable connections. Hence, the service saddle stands out distinctly in its ability to prevent movement while maintaining a sturdy connection.
