Pipe bends can be supplied to us bare or already coated. If bare, we would have them sandblasted then we can coat them with your preferred corrosion barrier (tape wrap, shrink sleeves, epoxy), specific to your maximum operating temperature. After this layer of coating, we can insulate with half-shells for whatever thickness you need. For the top coat, we would apply either tape wrap, shrink sleeves, or polyurea, according to customer preference.
