Indonesia's industrial and economic development is showing positive trends. According to Antارا news agency, the Indonesian Ministry of National Development Planning will promote the development of five priority industrial sectors from 2025 to 2029, namely natural resources industry, industrial services, labor-intensive industries, basic industries, and technology-intensive innovative industries. For the natural resources industry, it focuses on developing three industries: agriculture, mining and energy, and marine fisheries.

In terms of specific data, Pranjul Bhandari, Chief India and Indonesia Economist at HSBC Global Research, predicts that Indonesia's economy will grow by 5.1% year-on-year in 2025, slightly higher than the 4.9% data in the third quarter of 2024. This growth is mainly due to the gradual recovery of manufacturing and exports.

Overall, Indonesia's industrial and economic development has great potential and broad prospects. With the continuous promotion and implementation of relevant policies, Indonesia's industrial structure will be further optimized, and its international competitiveness will be continuously enhanced.

### Key Points for the Construction Technology of Long-Distance Pipeline Projects in Chemical Enterprises

The construction technology of long-distance pipeline projects in chemical enterprises is crucial to ensure safe and efficient transportation. Here are the key points:

1. **Route Selection**: Carefully select the route, considering factors such as terrain, geology, and existing infrastructure to minimize environmental impact and construction challenges.

2. **Pipe Material**: Choose appropriate pipe materials based on the nature of the chemicals transported, such as carbon steel or stainless steel, ensuring they have sufficient strength and corrosion resistance.

3. **Anti-Corrosion Coating**: Apply high-quality anti-corrosion coatings inside and outside the pipes to protect them from chemical reactions and extend their service life.

4. **Welding Quality**: Ensure high-quality welding during pipe installation, with strict control over welding parameters and procedures to guarantee joint strength.

5. **Testing and Inspection**: Conduct comprehensive testing and inspection, including pressure testing and non-destructive testing, to detect and address any defects or weaknesses.

6. **Construction Management**: Implement effective construction management practices, including proper planning, scheduling, and coordination of resources to ensure timely and cost-effective completion.

7. **Safety Measures**: Prioritize safety throughout the construction process, with measures in place to protect workers and the environment from potential hazards.

8. **Compliance with Standards**: Adhere to relevant industry standards and regulations to ensure the project meets all necessary requirements.

In summary, the construction technology of long-distance pipeline projects in chemical enterprises requires careful consideration of various factors, including route selection, material choice, anti-corrosion measures, welding quality, testing and inspection, construction management, safety, and compliance with standards. By following these key points, the reliability and efficiency of the pipeline system can be ensured.

# Strengthening the Management of Double Flange Force Transmission Joints in Pipelines to Ensure Unimpeded Transportation for Indonesian Chemical Enterprises

In the chemical industry of Indonesia, pipelines play a crucial role in transporting various chemicals. The double flange force transmission joints are key components that ensure the stability and reliability of the pipeline system. To guarantee the unimpeded transportation in chemical enterprises, it is essential to strengthen the management of these joints.

Firstly, regular inspections must be conducted. This includes checking the integrity of the flanges, bolts, and gaskets. Any signs of wear, corrosion, or damage should be promptly addressed. For example, if the gaskets are found to be degraded, they should be immediately replaced to prevent leaks.

Secondly, proper installation is vital. During the installation process, strict adherence to technical standards is necessary. The alignment of the flanges must be precise to avoid uneven force distribution, which could lead to joint failure. Additionally, the bolts should be tightened to the specified torque to ensure a secure connection.

Maintenance and lubrication are also important aspects. Regular lubrication of the moving parts can reduce friction and wear, extending the service life of the joints. Moreover, maintaining a clean environment around the joints can prevent the accumulation of dirt and debris, which may interfere with their normal operation.

In conclusion, by strengthening the management of double flange force transmission joints through regular inspections, proper installation, maintenance, and lubrication, we can effectively ensure the unimpeded transportation of chemicals in Indonesian chemical enterprises, promoting the stable and efficient operation of the industry.

In conclusion Indonesian chemical companies are increasingly demanding double flange force transmission joints in the field of pipeline construction These joints play a crucial role in connecting compensating and protecting within pipeline systems Proper installation and use of expansion joints are essential for ensuring the normal operation of pipeline systems and extending their service life Therefore Indonesian chemical companies should place greater emphasis on double flange force transmission joints improve the quality of pipeline construction and contribute to the sustained development of Indonesia's economy Diligence is rewarded with success kindness with contentment honesty with integrity commerce with trust and professionalism with excellence ZhongYuan wishes Indonesian customers of double flange force transmission joints the following Since cooperation with both new and old customers is the most precious asset of a company in the coming days we will cherish it even more May everyone be happy healthy and may everything go smoothly
