A sliding hanger is used when thermal horizontal movement is a factor. This type of hanger allows for horizontal movement as the pipe expands or contracts due to temperature changes. It helps prevent excessive stress on the piping system and supports its movement.
When thermal horizontal movement is a factor, a slip expansion joint hanger is commonly used. These hangers allow for lateral movement due to temperature changes, preventing stresses on the piping system.
The weight of an anchor can vary depending on its size and design. On average, an anchor used for recreational boating can weigh between 5 pounds (2.3 kg) to 50 pounds (22.7 kg). For larger vessels, the anchor's weight can range from several hundred pounds to several tons.
For thermal horizontal movement, expansion hangers are typically used. These hangers accommodate thermal expansion and contraction of the piping system to prevent stress or damage.

It depends on the tonnage of the boat and the type of seabed the anchor lies in. Smart boater carry at least 2 anchors, one for sandy bottoms and one for rocky bottoms. In larger ships, the length and weight of anchor chain paid out is also a factor.
The weight of an anchor is not as important as the type and design of the anchor used. Finding the appropriate anchor will also depend on the type of boat and the composition of the bottom of the body of water it is to be used in. In addition, lighter anchors are (obviously) easier for the boater to handle. Check with local boat shops or experienced boaters to find the right anchor.
A mushroom anchor should only be used for small, light-weight boats.

The rH factor of blood determines if it's positive or negative. For instance, O+ is rH positive O-type blood. The universal donor between the AB type and the rH type is the AB positive blood type.

Drywall anchors can typically hold between 10 to 50 pounds, depending on the type and size of the anchor used. It is important to follow the manufacturer's guidelines for the specific anchor being used to ensure proper weight capacity.
The top of a chief's anchor typically refers to the flukes or arms of the anchor, which are the parts designed to dig into the seabed for holding power. In nautical terminology, the "crown" is often used to describe the top part of the anchor where the shank and flukes meet. Anchors play a crucial role in securing a vessel, and the design can vary based on the type of anchor being used.
