What type of hanger is described as having two bolts that secure the pipe in place?

The type of hanger that is characterized by having two bolts securing the pipe in place is known as a double-bolt hanger. This design is effective for providing a stable and secure support for the piping system, ensuring that it can handle the weight of the pipe and any thermal expansion without shifting.

Double-bolt hangers are particularly useful in applications that require additional support and stability, as the two bolts create a firm grip around the pipe, minimizing movement and reducing the risk of stress over time. This makes them ideal for use in a variety of installations where the integrity and alignment of the piping system are critical.

Other types of hangers, such as clevis and adjustable ring hangers, each serve different functions and may not provide the same level of secure attachment as a double-bolt hanger.
