Problems solved by technology

However, the RCC-M (i.e., the design and construction rules for pressurized water reactor nuclear island mechanical equipment) commonly used in the world today only stipulates the design requirements and test acceptance criteria for standard supports and hangers, but does not specify specific test fixtures and test methods.

Embodiment 1

[0053] figure 1 It shows a standard support and hanger test fixture for nuclear grade pipelines when the angle between the load direction of the support pipe clamp and the horizontal direction is 90°, which includes:

[0054] The test main stand 7 is fixed on the ground;

[0055] Tooling assembly, the tooling assembly is adjustably installed on the test main frame 7, the tooling assembly includes an adjustment connecting plate 5, and a plurality of bolts are provided on the test main frame 7 and the adjusting connecting plate 5 Bolts pass through the bolt holes and cooperate with nuts to detachably connect the adjustment connecting plate 5 to the test main frame 7; at the same time, the bracket pipe clamp 4 can be installed on the above-mentioned adjusting connecting plate 5, so that all The position of the bracket pipe clamp 4 is fixed. It should be noted that the adjustment connecting plate 5 can be installed to different positions of the test main frame 7 through the bolt...

Embodiment 2

[0061] image 3 It shows a standard support and hanger test fixture for nuclear-grade pipelines when the angle between the load direction of the bracket pipe clamp and the horizontal direction is 45°. The difference between this embodiment and Embodiment 1 is that the tool assembly includes an adjustment connection Plate 5 and triangular-shaped tooling 13; wherein the triangular-shaped tooling 13 is a right-angled triangle as a whole, including two right-angled side plates and a slanted plate, for detachably connecting the adjusting connecting plate 5 .

[0062] Specifically, a plurality of bolt holes are provided on the two right-angle side plates, a slant plate, the test main frame 7 and the adjustment connecting plate 5, and the bolts pass through the bolt holes and cooperate with nuts, and the adjusting connecting plate 5 is detachably connected to the inclined plate, and any one of the right-angle side plates is detachably connected to the test main frame 7, so that the p...

Embodiment 3

[0065] Figure 4 It shows a standard support and hanger test tooling for nuclear grade pipelines when the angle between the load direction of the bracket pipe clamp and the horizontal direction is 0°, and the tooling assembly also includes an adjustment connecting plate 5 and a triangular tooling 13; wherein the The triangular-shaped tooling 13 is a right-angled triangle as a whole, including two right-angled side plates and a slanted plate for detachably connecting the adjusting connecting plate 5 . The difference from Embodiment 2 is that the two right-angled side plates, one slant plate, the test main frame 7 and the adjustment connecting plate 5 are all provided with a plurality of bolt holes, and the bolts pass through the bolt holes and cooperate with the nuts. The adjustment connecting plate 5 is detachably connected to any one of the right-angled side plates, and the other right-angled side plate is detachably connected to the main test frame 7, so that the triangular ...

Abstract

The invention discloses a nuclear-grade pipeline standard support and hanger testing tool and a testing method. The tool comprises a main testing rack serving as a supporting base, a support pipe clamp used for fixing a pipelinesimulation body, an adjusting connecting plate used for installing the support pipe clamp and an actuator connected with a rigid connecting block and a rigid pull rod and used for applying loads on the support pipe clamp. The method includes the steps of component installing, preloading, stress measuring, unloading and conformity assessment. The nuclear-grade pipeline standard support and hanger testing tool is capable of fast and effectively carrying out tests according to the requirement of RCC-M specifications to obtain test data corresponding to the acceptance criteria and then judge compliance of the standard support.

Description

technical field [0001] The invention relates to the field of nuclear-grade pipeline support and hangers in nuclear power plants, in particular to a test tool and test method for nuclear-grade pipeline standard support and hangers. Background technique [0002] Pipe support and hanger is an important part of the nuclear power engineering piping system and an important guarantee for the safe operation of the nuclear power plant piping system. Whether the layout of pipe supports and hangers is reasonable, whether the structure selection is appropriate, and whether the quality is reliable directly affects the stress state of pipes under different working conditions, and then affects the safe operation and service life of nuclear power plants. At the same time, due to the huge number of pipe supports and hangers, whether to use standardized support and hanger products has an important impact on the construction progress and cost of the project. [0003] There are three types of ...
