Hard Surfacing Wear Resistant Pipe

Surfacing wear-resistant pipe is a new type of wear-resistant pipe. It uses steel pipe as the base, and the wear-resistant layer and the base form a solid metallurgical combination of super wear-resistant alloy materials. The inner wall is made of surfacing welding, which is suitable for the production of wear-resistant pipes with small diameters. The surfacing wear-resistant pipe can be divided into two types according to the processing method, one is the inner wall surfacing steel pipe, and the other is the coiled wear-resistant composite steel pipe. The difference between them is that the rolled wear-resistant composite steel pipe can only be deformed and rolled into a tube when it is strongly squeezed by the rolling machine, so the adhesion between the wear-resistant layer and the substrate will be seriously damaged, resulting in falling off and falling blocks.

The impact resistance and vibration resistance performance will be greatly reduced. Due to the plasticity of the substrate and the brittleness of the wear-resistant layer, and all the rolled tubes have joints, it is inevitable that the ovality error will be large. The surfacing wear-resistant straight pipe produced according to the drawings provided by the customer is used for coal feeding pipe, material conveying pipe, etc., with high machining accuracy, high wear resistance, high impact resistance, convenient welding performance, high performance Although the surface cost of using wear-resistant surfacing pipes increases, considering the service life of the parts, maintenance costs, downtime losses, etc., the cost performance is about 2 to 4 times higher than that of ordinary materials.

The chromium carbide surfacing wear-resistant pipe not only has excellent wear resistance, high temperature resistance and impact resistance, but also has good toughness, excellent mechanical and thermal shock resistance, good weldability and easy installation. It is especially suitable for wear and impact in alpine and high temperature environment. Such as electric power, metallurgy, coal, mining, cement and other industries material transportation. Compared with other wear-resistant pipes, this product has high cost performance, long service life and low investment cost.
