They are made of heat-resistant round steel, and the heat-resistant coating is supported by the rake nails. The rake nails help prevent the heat-resistant coating from collapsing and cracking during construction and heating, so the structural design and connection method of the rake nails are very important; at present, the existing rake nails are usually divided into "V" shape and "Y" shape. Traditional micro rake nails require a large number of welding, and there are many welding points in one square, so the construction process is more troublesome. Due to the different expansion coefficients of the pipeline wall and the rake nails, a tensile force is formed after heating. Due to the tensile force, the welding points of some pipeline walls and rake nails are easily loosened, and the firmness is insufficient. The rake nails are prone to loosening, affecting the life of the wear-resistant layer. The steel mesh needs to be cut and laid before installation, and the construction process is more troublesome.
