Abstract
The utility model provides a kind of cooling device reducing built-up welding contraction problem, it is characterized in that, comprise bracing frame, bracing frame is provided with latex water pipe, and latex water pipe connects the first steel pipe, first fastener for connection water pump, water pump connects the bottom of the first tank, and the top of the first tank connects the second steel pipe, the bottom of the second fastener for connection first tank, the top of waiting to pile Coiling Welded Pipe is located at by bracing frame and latex water pipe, and the first tank is located at the below of waiting to pile Coiling Welded Pipe.The utility model structure is simple, cost is low, and while can be implemented in steel pipe inner wall built-up welding, outer wall is water-spraying control simultaneously, obviously improves heap postwelding steel pipe inner wall contraction distortion problem in actual production process.
Description
Technical field
The utility model relates to a kind of cooling device reducing built-up welding contraction problem.
Background technology
Built-up welding is process fast as the one economy of material surface modifying, be applied to more and more widely each industrial department part manufacture and in repairing.In South China Sea Deep Water project, relate to many pipelines all need inner wall overlaying, not only need the design strength of pipeline, also require medium contact surface corrosive.But due to the very complicated residual stress that Thermal Cycle is brought, the geometry deformation that mother metal is very complicated can be caused.Compound pipe can form the tip-tilted shape in edge at heap postwelding.This multiple tube is along with the reduction of wall thickness, and deflection also increases.
Publication number is disclose a kind of built-up welder wear-resistant composite board cooling device in the Chinese patent of CN201799762U, and it comprises the location-plate that a piece supports described wear-resistant composite board, and the below of described location-plate is provided with a cooling water input structure.Described cooling water input structure is made up of coolant intake pipe, coolant outlet hose and the tank of installing described input pipe and efferent duct.Its shortcoming is: 1, be only applicable to composite plate, is not suitable for multiple tube; 2, cannot recycle for cooling water.
Summary of the invention
The purpose of this utility model is providing the cooling system that a kind of structure is simple, can reduce built-up welding multiple tube contraction distortion problem.
In order to achieve the above object, the utility model provides a kind of cooling device reducing built-up welding contraction problem, it is characterized in that, comprises bracing frame, bracing frame is provided with latex water pipe, latex water pipe connects the first steel pipe, the first fastener for connection water pump, and water pump connects the bottom of the first tank, the top of the first tank connects the second steel pipe, the bottom of the second fastener for connection first tank, the top of waiting to pile Coiling Welded Pipe is located at by bracing frame and latex water pipe, and the first tank is located at the below of waiting to pile Coiling Welded Pipe.
Preferably, the first described steel pipe is provided with water pressure gauge near one end of latex water pipe.
Preferably, the diameter of described latex water pipe is 6-10mm.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model structure is simple, cost is low, and while can be implemented in steel pipe inner wall built-up welding, outer wall is water-spraying control simultaneously, obviously improves heap postwelding steel pipe inner wall contraction distortion problem in actual production process.
2, the utility model does not contact with build-up welder, can not affect built-up welding effect;
3, the cooling water in the utility model can realize recycling, and the flow of water controls by water pressure gauge.
Accompanying drawing explanation
Fig. 1 reduces the cooling device structural representation that problem is shunk in built-up welding.
Detailed description of the invention
For making the utility model become apparent, hereby with embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in Figure 1, the cooling device structural representation of problem is shunk for reducing built-up welding, the cooling device of problem is shunk in described reduction built-up welding, comprise bracing frame 4, bracing frame 4 is provided with latex water pipe 7, latex water pipe 7 connects the first steel pipe 5, first steel pipe 5 connects water pump 4, water pump 4 connects the bottom of the first tank 3, the top of the first tank 3 connects the second steel pipe 2, second steel pipe 2 connects the bottom of the first tank 1, and the top of waiting to pile Coiling Welded Pipe 9 is located at by bracing frame 4 and latex water pipe 7, and the first tank 3 is located at the below of waiting to pile Coiling Welded Pipe 9.The first described steel pipe 5 is provided with water pressure gauge 6 near one end of latex water pipe 7.The diameter of described latex water pipe 7 is 8mm.
During use, while use surfacing equipment 10 carries out inner wall overlaying nickel-base alloy 625 to 4 cun of seamless steel pipes (wall thickness 8.56mm), water-spraying control is carried out to outer wall.Built-up welding multiple tube inwall shrinks problem obviously to be improved, and reaches 20mm be reduced to and be less than 3mm by maximum deformation quantity.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
