Detailed Description
Embodiments of the present utility model will be described in more detail below with reference to the drawings and reference numerals, so that those skilled in the art can practice the present utility model after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The utility model provides a double-jack reinforced composite pipe convenient to seal, which is shown in fig. 1-2, and comprises a pipe body 10, wherein the pipe body 10 comprises a metal inner pipe 11 and a fiber reinforced layer 12 coated on the outer surface of the metal inner pipe 11. The metal inner tube 11 can be made of stainless steel, and the fiber reinforced plastic layer 12 can be wound on the surface of the metal inner tube 11 in a fixed length manner to form a composite tube.
The two ends of the pipe body 10 are provided with sockets 20 to form a double-socket pipe. Specifically, the socket 20 comprises a socket inner pipe 21 connected with the metal inner pipe 11, a fiber cushion layer 22 coated on the outer surface of the socket inner pipe 21, and a metal socket pipe 23 sleeved on the outer surface of the fiber cushion layer 22, wherein the fiber cushion layer 22 is connected with the fiber reinforced layer 12 into a whole, and the metal socket pipe 23 is further provided with a lap joint part 24 connected with the socket inner pipe 21.
