Abstract
The utility model relates to a kind of boiler internal piping anti-abrasion cover structure, and belong to inner tube architecture technical field, it comprises pipe and anti-abrasion cover, it is characterized in that, described tube exterior clamps the pipe clamp of cooperation, and on described pipe clamp, anti-abrasion cover is fixed in spot welding.Be specially the phenomenon such as undercut, burn-through that may cause when it effectively can reduce spot welding anti-abrasion cover, strengthen piping abrasionproof ability, extend piping running time, reduce boiler piping hidden danger.
Description
Technical field
The utility model relates to boiler internal tube structure technical field, is specially a kind of boiler internal piping anti-abrasion cover structure.
Background technology
Boiler operationally internal environment is more severe, wherein in flue gas, the particle of slag inclusion has strong wearing and tearing to boiler internal piping, this wearing and tearing be have very much destructive, when the wall thickness of piping is worn down to the wall thickness used lower than design permission, just may cause the situations such as leakage, booster thus cause boiler shutdown, to run unit, causing damage by gas electric unit.In order to reduce the wearing and tearing of flue gas to piping, when boiler design, just at wear and tear violent place or piping wall thickness reduction place of part piping, anti-abrasion cover being installed, strengthening piping abrasionproof ability, reduce potential safety hazard, improve boiler operation time.But the installation of anti-abrasion cover often direct spot welding on piping, because conventional piping wall thickness is thinner, directly on piping, spot welding easily causes burn-through, undercut, slag inclusion etc., these situations are particularly evident when boiler erection Site Welding anti-abrasion cover, and therefore direct spot welding on piping adds the potential safety hazard of piping on the contrary.
Summary of the invention
In order to solve the problem, the utility model provides a kind of boiler internal piping anti-abrasion cover structure, the phenomenon such as undercut, burn-through that may cause when it effectively can reduce spot welding anti-abrasion cover, strengthens piping abrasionproof ability, extend piping running time, reduce boiler piping hidden danger.
Its technical scheme is such: a kind of boiler internal piping anti-abrasion cover structure, it comprises pipe and anti-abrasion cover, it is characterized in that, described tube exterior clamps the pipe clamp of cooperation, and on described pipe clamp, anti-abrasion cover is fixed in spot welding.
It is further characterized in that, described pipe clamp is circular pipe clamp, and described pipe clamp comprises circular arc medial surface, and the circular arc medial surface of described pipe clamp matches with the external diameter of described pipe, and described pipe clamp suit is clamped in described tube exterior;
Described pipe clamp two ends are fixedly connected with;
Described pipe clamp two ends are fixed by spot welding or screw and nut screw connection are fixed;
Secure bond place, described pipe clamp two ends arranges along flow of flue gas direction.
After adopting structure of the present utility model, anti-abrasion cover point is welded on pipe clamp, and anti-abrasion cover is not directly and pipe spot welding, the phenomenon such as undercut, burn-through that may cause when effectively can reduce spot welding anti-abrasion cover, anti-abrasion cover strengthens piping abrasionproof ability, extends piping running time, reduces boiler piping hidden danger.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is A-A place sectional view in Fig. 1.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, a kind of boiler internal piping anti-abrasion cover structure, it comprises pipe 3 and anti-abrasion cover 1, and pipe 3 outside clamps the pipe clamp 2 of cooperation, and on pipe clamp 2, anti-abrasion cover 1 is fixed in spot welding; Pipe clamp 2 is circular pipe clamp, and pipe clamp 2 comprises circular arc medial surface, and the circular arc medial surface of pipe clamp 2 matches with the external diameter of pipe 3, and it is outside that pipe clamp 2 suit is clamped in pipe 3, realizes pipe clamp 2 and be clamped on pipe 3.
Pipe clamp 2 two ends are fixedly connected with, and can realize pipe clamp 2 better and be clamped on pipe 3; Pipe clamp 2 two ends are fixed by spot welding, also can be fixed by alternate manner, and such as screw and nut screw connection realize fixing; Secure bond place, pipe clamp 2 two ends arranges along flow of flue gas direction 4, can reduce the disturbance to flue gas.
