Abstract
The invention discloses a novel high-temperature-resistant and anti-corrosion composite pipe, comprising a composite pipe main body, a connecting head, a ceramic layer and a polycrystalline corundum layer. The two ends of the composite pipe main body are provided with connecting heads, and the connecting heads are provided with connecting heads. The main body of the composite pipe is composed of a wear-resistant layer, an anti-corrosion layer, a steel layer, a transition layer, a ceramic layer, a high temperature resistant layer and a polycrystalline corundum layer, and a high temperature resistant layer is provided outside the polycrystalline corundum layer, and the outside of the high temperature resistant layer is A ceramic layer is arranged, a transition layer is arranged outside the ceramic layer, a steel layer is arranged outside the transition layer, an anti-corrosion layer is arranged outside the steel layer, and a wear-resistant layer is arranged outside the anti-corrosion layer. The invention has excellent wear resistance, heat resistance, mechanical resistance and thermal shock resistance, and the connection is convenient by setting the connecting head, and the connection is more tight by setting the protrusions and grooves, and it is compatible with the traditional composite Compared with the tube, its service life is longer.
Description
technical field [0001] The invention relates to the technical field of corundum composite pipes, in particular to a novel high temperature resistant and anti-corrosion composite pipe. Background technique [0002] At present, wear-resistant pipe fittings are essentially different from traditional steel pipes, wear-resistant alloy cast steel pipes, cast stone pipes, steel-plastic pipes, and steel rubber pipes. The outer layer of the wear-resistant pipe is seamless steel pipe, and the inner layer is corundum. The hardness of the corundum layer is as high as HV1100-1400, which is equivalent to tungsten-cobalt cemented carbide, and its wear resistance is more than 20 times higher than that of carbon steel pipes. The wear resistance of wear-resistant pipes mainly depends on the corundum layer with a thickness of several millimeters in the inner layer, which is a qualitative leap compared with wear-resistant alloy cast steel pipes and cast stone pipes, which rely on both composit...
