Abstract
A kind of efficient heat transfer anticorrosion screwed pipe, including tube body, the tube body inner and outer surfaces are respectively provided with thread segment, the inner surface of tube body is coated with corrosion-resistant finishes, and the tube body inner and outer surfaces are provided with thread segment, this kind of thread segment can increase heat exchange area, enhance heat exchange efficiency, and inner surface of tube body is provided with corrosion-resistant finishes, high resistance to corrosion can increase the service life of heat exchanger, reduce maintenance cost.
Description
Technical field
The utility model relates to a kind of heat exchanger tubes, more particularly, to a kind of efficient heat transfer anticorrosion screwed pipe.
Background technique
Shell-and-tube heat exchanger is also known as tubular heat exchanger, belongs to one of dividing wall type heat exchanger, this heat exchanger structure
Relatively simple, operation is reliable, can use under high temperature and pressure, is heat exchanger most widely used at present.Shell-and-tube in the prior art
The heat exchanger tube of heat exchanger mostly uses common smooth inner wall pipe, and the effective heat exchange area of this heat exchanger is smaller, and fluid is exchanging heat
It is not easy to form turbulent flow in pipe, causes the heat exchange efficiency of this shell-and-tube heat exchanger lower, limit to it in the application in market.
Nowadays, for thread heat exchange pipe gradually instead of smooth inner wall pipe, this is a much progress on heat exchange efficiency,
But this simple thread heat exchange pipe can not meet human wants, and this kind of thread heat exchange pipe resists in corrosion-resistant energy
Very low, low resistance to corrosion shortens the service life of heat exchanger, increases maintenance cost.
Utility model content
The utility model is adopted the technical scheme that solve technical problem present in background technique:
A kind of efficient heat transfer anticorrosion screwed pipe, including tube body, the tube body inner and outer surfaces are respectively provided with thread segment, institute
The inner surface of tube body stated is coated with corrosion-resistant finishes.
As the further technical solution of the utility model, the corrosion-resistant finishes is enamel layer.
As the further technical solution of the utility model, the outer surface of tube body is provided with zinc layers.
As the further technical solution of the utility model, the thread segment includes two kinds of screw threads, one of screw thread
Screw pitch it is bigger than another.
As the further technical solution of the utility model, the tooth cross section of the thread segment is triangle, trapezoidal or square
Shape.
Using having the beneficial effect that after the program, the tube body inner and outer surfaces are provided with thread segment, this kind of thread segment
It can increase heat exchange area, enhance heat exchange efficiency, and inner surface of tube body is provided with corrosion-resistant finishes, high resistance to corrosion can increase
The service life of heat exchanger, reduces maintenance cost.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model.
Fig. 2 is the front view of the utility model.
Fig. 3 is the sectional view of the utility model.
Fig. 4 is the partial enlarged view of the sectional view of the utility model.
Figure label: 1- tube body, 2- compound thread section, 3- short distance screw thread, 4- long are away from screw thread.
Specific embodiment
The specific implementation of the utility model is described in detail in a preferred way below in conjunction with attached drawing, it should be understood that
It is specific embodiment described herein is merely to illustrate and explains the utility model, the protection scope of the utility model is simultaneously
It is not limited to following specific embodiments.
A kind of efficient heat transfer anticorrosion screwed pipe, including tube body 1, it is characterised in that: 1 inner and outer surfaces of tube body are equal
Thread segment 2 is set, and 1 inner surface of tube body is coated with corrosion-resistant finishes.
Further, the corrosion-resistant finishes is enamel layer, and this enamel layer can make interior walls be smooth and make corrosion-resistant
Property enhancing.
Further, 1 outer surface of tube body is provided with zinc layers, the preferred electric-arc thermal spray coating of the processing method of the zinc layers
Method, this method have many advantages, such as that zinc layers good compactness, adhesive force are strong, environmental pollution is small.
Further, the thread segment 2 includes long away from screw thread 4 and short distance screw thread 3, and as its name suggests, the length is away from screw thread 4
Screw pitch it is bigger than the screw pitch of short distance screw thread 3.
Further, the tooth cross section of the thread segment 2 is triangle, trapezoidal or rectangle, it is preferable that the tooth in this programme is horizontal
Section is triangle, and the tooth cross section of triangle increases on heat exchange area.
From the above: 1 inner and outer surfaces of tube body are provided with thread segment 2, the thread segment 2 by two kinds not
With the different screw thread composition of screw pitch, this kind of thread segment 2 can increase heat exchange area, enhance heat exchange efficiency, and 1 inner surface of tube body is arranged
There is corrosion-resistant finishes, high resistance to corrosion can increase the service life of heat exchanger, reduce maintenance cost.
It is above-described, it is only that being preferably for the utility model applies example, although the utility model has been shown and described
Embodiment, it will be understood by those skilled in the art that: in the case where not departing from the principles of the present invention and objective
These embodiments can be carried out with a variety of variations, modification, replacement and deformation, the scope of the utility model is by claim and its waits
Jljl limits.
