[0013] Example 1: See Figure 1 A water supply steel disease simulation pipeline includes a steel pipeline 1, the steel pipeline 1 has an anti-corrosion layer, a bottom cover 2 is provided at the bottom of the steel pipeline 1, a top cover 3 is provided at the top, an observation port 4 is provided on the top cover 3, an inlet pipe 5 is provided near the top of the steel pipeline 1, and an inlet pipe valve is provided on the inlet pipe 5, a water outlet pipe 6 is provided near the bottom of the steel pipeline 1, and an outlet pipe valve is provided on the outlet pipe 6; wherein, a disease simulation area 7 is provided in the steel pipeline, and the disease simulation area includes a rust simulation area, or a scaling simulation area, or an anti-corrosion shedding simulation area (that is, the anti-corrosion layer is removed in this area to simulate the disease).
[0014] In the embodiment, the rust simulation area comprises a rust base layer (i.e., the anti-corrosion layer is removed from the rust simulation area, exposing a steel layer, which serves as the rust base layer). A first rapid-setting mortar portion (made of rapid-setting mortar) is disposed on the rust base layer. Paint (e.g., reddish-brown paint, red paint, or other colors to simulate rust, preferably reddish-brown paint) is sprayed on the first rapid-setting mortar. The above is an example of a rust simulation area, and reference may be made to other forms of the prior art.
[0015] In the embodiment, the scaling simulation area has a scaling base (i.e., the anti-corrosion layer is removed from the scaling simulation area to expose the steel layer, which is the scaling base), and a number of steel wires are welded at the scaling base (the steel wires are attached to the scaling base, and one way of arranging the steel wires can refer to Figure 2 , which is only an example and not a limitation), a second rapid setting mortar portion (made of rapid setting mortar) is provided at the steel wire.
[0016] In an embodiment, the bottom cover and the steel pipe are connected via a flange, and the top cover and the steel pipe are connected via a flange.
[0017] How to make a simulated pipeline:
[0018] 1. Prepare a section of steel water supply pipe.
[0019] 2. Determine the degree of disease simulation required and conduct disease simulation.
[0020] 1. Rust:
[0021] Step 1: Determine the scale area size (area size) of the corrosion simulation area, remove the anti-corrosion layer inside the pipeline, and reveal the corrosion base layer (i.e., the exposed steel layer is used as the corrosion base layer);
[0022] Step 2: a second rapid setting mortar portion (made of rapid setting mortar) is set on the corroded base layer, and paint (such as reddish brown paint) is sprayed on the second rapid setting mortar portion to simulate the corrosion condition.
[0023] 2. Scaling:
[0024] Step 1: Determine the size of the scaling simulation area, remove the anti-corrosion layer inside the pipeline, and reveal the scaling base (i.e., the exposed steel layer serves as the scaling base);
[0025] Step 2: Weld steel wires of different lengths to the scaling base in the scaling simulation area to ensure that the mortar solidifies quickly without falling off;
[0026] Step 3: Set up the first rapid setting mortar section in the scaling simulation area, that is, use rapid mortar to simulate scaling on the pipeline.
[0027] 3. Anti-corrosion and shedding:
[0028] Determine the degree of anti-corrosion shedding in the anti-corrosion shedding simulation area, and simulate the removal of the anti-corrosion layer inside the pipeline in the anti-corrosion shedding area.
[0029] 3. After simulating the required disease, install the water inlet and outlet of the pipeline (inlet and outlet pipes). The water inlet (inlet pipe) can be set (weld the water inlet pipe at the hole after drilling) at the upper and lower positions of the device (the upper position is preferred), and the water outlet (outlet pipe) is at the bottom of the device (weld the water outlet pipe at the hole after drilling). Valves (such as gate valves) need to be installed on the inlet and outlet pipes to control the water flow. The water inlet (inlet pipe) needs to be connected to the water supply pipe with a pressure gauge and flow meter;
[0030] 4. The bottom cover of the device is installed (can be installed by welding or flange, preferably flange) and the top cover is installed (can be installed by welding or flange, preferably flange). An installation position is reserved at the observation port on the top cover for installing a pressure pipeline internal inspection device (reference can be made to existing technology, which can be used to obtain video data, including but not limited to pressure inspection robots, pressure inspection endoscopes, etc.).
[0031] The water supply steel pipeline disease simulator can simulate rust, scaling, and corrosion detachment. Combined with the internal inspection device, it collects video data of the disease, providing analytical reference data for maintenance. This not only provides a reference for the health of the pipeline network, but also provides powerful support for locating and maintaining pipeline defects, reducing pipeline operation risks, and improving water utilities' pipeline network operation and management capabilities.
[0032] Example 2: The solution is the same as Example 1, except that, in order to facilitate the use of the steel wire (strip), a plurality of steel wire structure blind holes are set on the surface, and the steel wire structure blind holes have internal threads.
[0033] Example 3: The solution is the same as Example 1 or 2, except that a top cover structure through hole is provided on the top cover for easy use, and a closing bolt is provided at the top cover structure through hole.
[0034] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions that fall within the principles of the present invention fall within the scope of protection of the present invention. For those skilled in the art, any improvements made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
