After achieving high growth rates of nearly 50% and over 32% in 2009 and 2010, respectively, in the first quarter of 2011, the growth rate of China's light vehicle sales fell sharply to 9%, while the growth rate in April fell to 3%. The introduction of government stimulus policies and the implementation of new car restriction policies in major cities have made the Chinese auto market lack of growth.
The research report predicts that Chinese auto parts suppliers will achieve strong growth in the next few years compared with the moderate growth of local automakers, among which the aftermarket is a major development opportunity. According to statistics, China's auto parts sales increased by 44% last year, which is higher than the growth rate of 37% of total vehicle sales, reaching more than RMB 16,000 million. The substantial increase in demand in the aftermarket will undoubtedly further benefit auto parts manufacturers. According to the report data, in 2010, the sales revenue of China's service and parts after-sales market reached RMB 224 billion. It is expected that by 2014, this figure will increase to 625 billion yuan.
Compared with vehicle sales, auto parts sales and service have higher profitability. Since 2009, China's auto parts suppliers have consistently occupied the highest position in global profits. Last year's profit rate reached 10%, which was higher than 7.6% of the total vehicle dealer's operating margin. Ai Ruibo analysis, taking the automobile sales group Zhongsheng as an example, in 2010, the gross profit of new car sales of the Group accounted for only 5.8% of the total gross profit, and the percentage of service gross profit reached 48.9%.
Tungsten carbide welding bars are commonly used in the oil and gas industry for various applications. These bars are made from a combination of tungsten and carbon, which results in a very hard and wear-resistant material. Here are some specific uses of tungsten carbide welding bars in the oil and gas industry:
1. Hardfacing: Tungsten carbide welding bars are used for hardfacing applications, where a wear-resistant layer is applied to drilling tools, valves, pumps, and other equipment exposed to abrasive environments. This helps to extend the lifespan of the components and reduce maintenance costs.
2. Drill bits: Tungsten carbide welding bars are used to manufacture drill bits for oil and gas exploration. The hard and durable nature of tungsten carbide makes it ideal for drilling through tough rock formations.
3. Wear plates and liners: Tungsten carbide welding bars are used to create wear plates and liners for equipment used in oil and gas production. These plates and liners protect the underlying metal surfaces from abrasion and corrosion, ensuring the longevity of the equipment.
4. Valve seats and seals: Tungsten carbide welding bars are used to manufacture valve seats and seals for oil and gas valves. The high hardness and wear resistance of tungsten carbide ensure reliable sealing and prevent leakage in critical applications.
5. Downhole tools: Tungsten carbide welding bars are used in the manufacturing of downhole tools such as stabilizers, reamers, and drill collars. These tools are subjected to high pressures, temperatures, and abrasive conditions, and tungsten carbide helps to enhance their durability and performance.
Overall, tungsten carbide welding bars play a crucial role in the oil and gas industry by providing wear resistance, hardness, and durability to various components and equipment.
