Abstract
The invention discloses a duplex metal composite elbow. The composite elbow comprises an arc-shaped carbon steel elbow pipe, the elbow pipe is in hollow structure, a wear-resisting layer is arranged on the inner wall of the elbow pipe, one end of each of two pipe connectors is connected on the inner wall of the wear-resisting layer at the two ends of the elbow pipe, and the other end of each of the two pipe connectors is arranged at the outer part of the elbow pipe. The duplex metal composite elbow has the advantages of high safety performance and corrosion resistance.
Description
Technical field:
The present invention relates to a kind of bimetal composite elbow.
Background technique:
The normal connection pipe fitting that uses elbow as two tubes in the piping erection; Existing elbow is generally cast steel etc., in long-term the use, is prone to produce corrosion, so just need do irregular maintenance to elbow; When the elbow seriously corroded; Need in time to change elbow, this not only reduces the Safety performance of elbow, and increases the cost of knowing clearly.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, the present invention provides a kind of Safety performance height, corrosion resistant bimetal composite elbow.
The object of the invention is realized through following technological scheme: a kind of bimetal composite elbow; Said composite elbow comprises arc carbon steel bend pipe; Bend pipe is a hollow-core construction; The inwall of bend pipe is provided with anticorrosive coat, all is connected with an end of interface tube on the inwall of anticorrosive coat two ends, and the other end of two interface tubes all places the outside of bend pipe.
The present invention compared with prior art has the following advantages: make elbow have good corrosion prevention performance through setting up anticorrosive coat; And bend pipe is a carbon steel, has high tenacity like this, when elbow and pipeline are welded; Both can guarantee elbow and pipeline firm welding, and can not produce seepage.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Label among the figure: 1-bend pipe, 2-anticorrosive coat, 3-interface tube.
Embodiment:
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show the embodiment of a kind of bimetal composite elbow of the present invention like Fig. 1, said composite elbow comprises arc carbon steel bend pipe 1, and bend pipe 1 is a hollow-core construction; The inwall of bend pipe 1 is provided with anticorrosive coat 2, all is connected with an end of interface tube 3 on the anticorrosive coat 2 two ends inwalls, and the other end of two interface tubes 3 all places the outside of bend pipe 1; Make elbow have good corrosion prevention performance through setting up anticorrosive coat 2; And bend pipe 1 is a carbon steel, has high tenacity like this, when elbow and pipeline are welded; Both can guarantee elbow and pipeline firm welding, and can not produce seepage.
