Embodiment Construction

[0018] The present application will be described in detail below in conjunction with specific embodiments.

[0019] Such as figure 1 A jacketed hydrostatic test device for a large-diameter FRP pipe is shown, which includes a cantilever arm 1 and a sleeve 2 sleeved outside the cantilever arm 1, the pipeline to be tested 3 is sleeved outside the sleeve 2, and the sleeve 2 and The two ends of the pipeline 3 to be tested are sealed and connected, and the middle section forms a cavity interlayer 4 for hydraulic testing. Wherein, the cantilever arm 1 is cylindrical, and is vertically installed on the fixed support 9 in the vertical direction; the sleeve 2 is a steel sleeve, which can be installed directly from the free end of the cantilever arm 1 by sliding-in sleeve. The wall has a double-layer structure, and a pressure-bearing bracket 22 is provided between the inner wall and the outer wall; the edge of the sleeve 2 close to the fixed end of the cantilever arm 1 is integrally pro...

Abstract

The invention discloses a large-diameter FRP pipe jacket type hydraulic test device, which comprises a cantilever arm and a sleeve sleeved on the cantilever arm, the pipeline to be tested is sleeved outside the sleeve, the sleeve and the pipeline to be tested The two ends are sealed and connected, and the middle section forms a cavity interlayer for hydrostatic testing. The structure design of this application is reasonable, easy to install and disassemble, saving time and procedures; the overall structure is stable, strong pressure bearing; the cavity interlayer used for hydraulic test is small in volume, the cross-sectional area of ​​the interlayer is small, and the formed axial force is small, And the test water consumption is less, and the hydraulic test speed is fast; through the sleeves of different specifications, it is used for the hydraulic test of multi-standard FRP pipes, which is more flexible and widely applicable.

Description

technical field [0001] The invention belongs to a hydraulic test device, in particular to a jacketed hydraulic test device for a large-caliber glass fiber reinforced plastic pipe. Background technique [0002] FRP pipe is a light-weight, high-strength, corrosion-resistant non-metallic pipe. Its pipe wall structure is reasonable and advanced, which can give full play to the role of materials. Under the premise of meeting the use strength, the rigidity is improved to ensure the stability of the product performance and reliability, and its application fields are wide. In order to further improve the quality of glass steel pipe products and the safety and reliability of use, all glass steel pipe manufacturers are working hard to strengthen inspection and testing methods. Especially at present, the hydrostatic test of large-diameter FRP pipelines usually requires a large-scale device to meet the large-scale water volume and axial force required; the traditional large-diameter hy...
