No, wear pads and corner guards cannot be used with all types of slings. Their compatibility depends on the material and design of the sling, as well as the specific lifting application. Wear pads and corner guards are typically used to protect slings from abrasion, cutting, and other forms of damage that can occur when the sling comes into contact with sharp edges or rough surfaces. 
For synthetic slings, such as nylon or polyester web slings, wear pads and corner guards are often used to extend the life of the sling by providing an additional layer of protection. These protective accessories are usually made from materials like leather, rubber, or heavy-duty fabric that can withstand friction and sharp edges.
However, for chain slings or wire rope slings, wear pads and corner guards are generally not used. These types of slings are inherently more resistant to abrasion and cutting due to their construction and material properties. Instead, other protective measures, such as using softeners or edge protectors specifically designed for chains or wire ropes, may be employed.
Additionally, the use of wear pads and corner guards must be carefully evaluated based on the specific lifting conditions, including the load's weight, shape, and the environment in which the lifting operation takes place. It's crucial to ensure that the protective accessories do not interfere with the sling's performance or compromise safety.
In summary, while wear pads and corner guards are beneficial for certain types of slings, particularly synthetic ones, they are not universally applicable to all sling types. Proper assessment and selection based on the sling type and lifting conditions are essential for safe and effective use.
