Recently, in the first batch of independently-innovated product catalogs issued by the Provincial Department of Science and Technology, the Provincial Development and Reform Commission, the Provincial Economic Commission and the Provincial Department of Finance, the “HR Energy Saving and Low Noise Roots Blower” produced by Sichuan Blower Manufacturing Co., Ltd. HR100, HR110, HR200, HR230 series of products and Tianfu Pharmaceutical Company's five products, such as “Radix Tablets”, entered the “Indigenous Innovation Product Directory of Sichuan Province”.
According to the Sichuan provincial independent innovation product certification implementation management measures (for trial implementation), the identified independent innovation products of Sichuan Province will be preferentially purchased in the procurement of fiscal resources such as government procurement and major project procurement within the administrative divisions of Sichuan Province, using financial funds. Major construction projects and major equipment and product procurement projects should first adopt independent innovation products. The above-mentioned short-listed products are an important result of the city's efforts to strengthen the capacity for independent innovation, and will play a positive role in accelerating industrial and product restructuring and upgrading.

Welding Bar

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.
