The increase in orders in the first half of the year was mainly from metallurgical valves In the first half of the year, the company's new orders for metallurgical valves are estimated to be around 200 million yuan, which is a significant increase. The reasons for the growth of metallurgical valves are as follows: First, the visibility after the listing is large; second, the national energy-saving and emission reduction promotion in the metallurgical industry is relatively large. In the first half of the year, the growth of metallurgical valves mainly came from technological transformation instead of new steel projects. In the first half of the year, the company’s metallurgical valves achieved an income of 103 million yuan, a year-on-year increase of 28.65%, a gross profit margin of 34.39%, and a year-on-year decrease of 5.1 percentage points, mainly due to factors such as the price increase of steel (4934, 21.00, 0.43%). The annual revenue is expected to grow by about 30%.
Nuclear orders in hand can support operations in the next two years. Nuclear power was affected by the Fukushima nuclear accident in the first half of the year. Orders dropped significantly. Orders were in the hands of about 600 million yuan. It is expected to deliver 200 million yuan this year, and it will deliver 300 million yuan next year. The business will not be affected temporarily.
Valuation and investment rating. Combined with the relative valuation method and the absolute valuation method, it is expected that the company's reasonable valuation range for the next one year will be 21.96-22.5 yuan, suggesting neutrality. The risk is that the future development of domestic nuclear power is not clear, and the economic cycle may lead to fluctuations in demand for metallurgical valves and slower-than-expected new product development.
1. Turn off the hydraulic system: Before replacing the hydraulic cylinder, it is necessary to turn off the system to avoid liquid leakage in the hydraulic system.
2. Disassembling the hydraulic cylinder: Disassembling the hydraulic cylinder requires the use of tools such as wrenches, screwdrivers, etc. Firstly, the hydraulic pipeline needs to be removed, and then the bolts of the hydraulic cylinder need to be removed to remove the hydraulic cylinder from the machine.
3. Check the hydraulic cylinder: Check if there is any damage to the hydraulic cylinder, and if there is any damage, replace it.
4. Install a new hydraulic cylinder: Install the new hydraulic cylinder onto the machine and secure the cylinder with bolts.
5. Connect hydraulic pipeline: Connect the hydraulic pipeline to the hydraulic cylinder, pay attention to the position and direction of the connection, and ensure that the connection is secure.
6. Test system: after replacing the hydraulic cylinder, it is necessary to test whether the system operates normally, check whether the hydraulic cylinder operates normally, and deal with any problem in time.
7. Cleaning work: Clean the liquid and debris in the hydraulic system to ensure that the system is clean and avoid any impact on the system.
