Abstract
The utility model discloses a metal threaded pipe, comprising a metal pipe wall, wherein a plurality of long-lead screws are arranged on an interior wall of the metal pipe wall, and the inner diameter of the screw is half of the external diameter. The metal threaded pipe provided by the utility model is capable of effectively increasing the flowing length of chemical media in the pipe as well as improving the heat exchange efficiency and increasing the chemical reaction speed.
Description
Technical field
The utility model relates to chemical industry heat exchange device, relates in particular to a kind of metal threaded pipe.
Background technology
The metal tube that existing chemical industry heat exchanger adopts be inside and outside all be the smooth face of cylinder, when chemical medium is inner through it, be stream mode basically; There is not stirring action; The core medium is difficult for and the outer medium generation heat exchange of pipe, has so both reduced heat exchange efficiency, has influenced chemical reaction velocity again.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of metal threaded pipe simple in structure, can effectively improve the length of flow of chemical mediator in pipe, improves heat exchange efficiency and chemical reaction velocity.
Technical scheme: for solving the problems of the technologies described above, the technical scheme of the utility model sampling is:
A kind of metal threaded pipe comprises metal pipe-wall, on the inwall of metal pipe-wall, is provided with multi-thread long helical pitch screw thread, and the internal diameter of screw thread is the half the of external diameter.
Adopt the metal tube of this structure, make chemical medium in whole pipe, rotate all the time, chemical medium is received stirring all along, thereby has improved heat exchange efficiency and chemical reaction velocity.
Beneficial effect: the metal threaded pipe that the utility model provides, can effectively improve the length of flow of chemical mediator in pipe, improve heat exchange efficiency and chemical reaction velocity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Be depicted as a kind of metal threaded pipe like accompanying drawing 1, comprise metal pipe-wall 1, on the inwall of metal pipe-wall 1, be provided with multi-thread long helical pitch screw thread 2, and the internal diameter of screw thread 2 is the half the of external diameter.Screw thread 2 can be extruded on special equipment, and caliber and pipe range can design as required, and screw thread 2 can adopt various tooth forms.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
