Novel wear-proof ceramic reducing pipe

Abstract

The invention discloses a novel wear-proof ceramic reducing pipe comprising a flange, a pipe body, two handles, a small-diameter connector and a large-diameter connector. The large-diameter connectoris provided with a large-diameter seal groove. The flange is arranged on one side of the large-diameter seal groove. The flange is provided with a threaded hole. The pipe body is arranged on one sideof the flange. The two handles are symmetrically arranged on the pipe body. The small-diameter connector is arranged on one side of the pipe body. The small-diameter connector is provided with a small-diameter seal groove. The outer portion of the pipe body is provided with an outer metal layer. Ceramic is arranged inside the outer metal layer. The outer metal layer and the ceramic layer are connected through adhesive. A hollow layer is arranged inside the ceramic layer. Due to the arrangement of the hollow layer, the use amount of materials is reduced; the flange is connected with the pipe body and the large-diameter connector in a welded manner. By the adoption of the large-diameter connector and the small-diameter connector, pipes of different calibers are conveniently installed. Due tothe handles, the ceramic reducing pipe is convenient to transport and move. Due to the large-diameter seal groove and the small-diameter seal groove, leakage is prevented from happening at connectionportions of the reducing pipe, and seal reliability is guaranteed.

Description

technical field [0001] The invention relates to the field of industrial pipelines, in particular to a novel wear-resistant ceramic reducer. Background technique [0002] Ceramic steel pipe is a kind of composite pipe that combines ceramics and metal organically.

[0002] Ceramic steel pipe is a kind of composite pipe that combines ceramics and metal organically. Ceramic steel pipe combines the advantages of high alumina hardness, good chemical inertness and steel, and has excellent wear resistance, corrosion resistance, heat resistance and thermal shock resistance. And mechanical shock resistance, the reducer is also called the size head, it is a chemical pipe fitting, mainly used for the connection of two different pipe diameters; the popular reducers on the market mainly include concentric reducers and eccentric There are two types of reducers, ceramic reducers have extremely high wear resistance, and their wear resistance is ten times higher than that of quenched medium carbon steel, which is better than tungsten carbide; ceramics are neutral materials, chemical Stable performance, excellent corrosion resistance and acid resistance, can resist various inorganic acids, organic acids, organic solvents, etc., and its corrosion resistance is more than ten times that of stainless steel; ceramic reducer has excellent heat resistance, and can withstand a temperature of 2000 Above ℃, it can work for a long time in the range of -50℃~900℃; the ceramic reducer can be connected by welding the outer steel pipe; the ceramic reducer can be connected with steel pipe, wear-resistant alloy cast pipe, cast iron pipe and cast stone pipe Relatively light in weight, easy to transport and install, ceramic reducers can be connected by welding, flanges, flexible quick joints, etc., and installation is very convenient; ceramic reducers can be used in thermoelectric, steel, non-ferrous Various pipelines in metal, mining, coal, chemical, petrochemical and other industries, but traditional ceramic reducers use more materials, and it is difficult to ensure that they will not leak. In addition, the movement, transportation and The packaging is relatively complicated, so we need to further improve the structure of the ceramic reducer to meet the requirements
