Problems solved by technology

However, the installation of the anti-wear cover is usually spot welded directly on the pipe system. Since the wall thickness of the commonly used pipe system is thin, spot welding directly on the pipe system is likely to cause weld penetration, undercut, slag inclusion, etc. It is especially obvious when welding the wear-resistant cover, so the spot welding directly on the piping system increases the safety hazard of the piping system

Embodiment Construction

[0012] See figure 1 , figure 2 As shown, a wear-resistant cover structure for the internal piping system of a boiler, which includes a pipe 3 and a wear-resistant cover 1, a pipe clamp 2 that is clamped on the outside of the pipe 3, and the wear-resistant cover 1 is fixed by spot welding on the pipe clamp 2; the pipe clamp 2 It is a circular pipe clamp. The pipe clamp 2 includes the inner surface of the arc. The inner surface of the arc of the pipe clamp 2 matches the outer diameter of the pipe 3. The pipe clamp 2 is clamped on the outside of the pipe 3 so that the pipe clamp 2 is clamped on the Tube 3 on.

[0013] The two ends of the pipe clamp 2 are fixedly connected, which can better realize the clamping of the pipe clamp 2 on the pipe 3; the two ends of the pipe clamp 2 are fixed by spot welding, and can also be fixed by other methods, such as screws and nuts for fixing; the pipe clamp 2 The fixed joints at both ends are arranged along the flue gas flow direction 4, whi...

Abstract

The invention relates to the technical field of a boiler inside pipe system structure, in particular to a boiler inside pipe system anti-abrasion cover structure with the advantage that phenomena of edge engaging, burn through and the like possibly caused during the spot welding of an anti-abrasion cover can be effectively reduced, the pipe system anti-abrasion capability is enhanced, the pipe system operation time is prolonged, and the boiler pipe system hidden danger is reduced. The boiler inside pipe system anti-abrasion cover structure comprises a pipe and an anti-abrasion cover, and is characterized in that a matched pipe clamp is arranged outside the pipe in a clamping way, and the anti-abrasion cover is fixedly arranged on the pipe clamp in a spot welding way.

Description

technical field [0001] The invention relates to the technical field of boiler internal piping structure, in particular to a boiler internal piping wear-resistant cover structure. Background technique [0002] The internal environment of the boiler is relatively harsh during operation, and the slag-containing particles in the flue gas have strong wear on the internal piping system of the boiler. This wear is very destructive. When the wall thickness of the piping system is worn below the design allowable When the wall thickness is used, it may cause leakage, pipe burst, etc., which will cause the boiler to shut down, and cause losses to the operating unit and the gas and electricity unit. In order to reduce the wear of the flue gas on the piping system, during the design of the boiler, wear-resistant covers are installed on parts of the piping system where the wear is severe or where the wall thickness of the piping system is thinned, so as to enhance the anti-wear ability of...
