Why is it a more effective drying method for heat-sensitive material freeze dryers?
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.

Firstly, the method effectively prevents the physical and chemical changes of the product, changes the biological structure and cell structure and characteristics, and makes it quickly enter the dormant state, effectively protecting the stability of the active ingredients of many heat sensitive drug biological products. For example, proteins and microorganisms do not degenerate and lose their biological activity;
Secondly, the lyophilized product has a loose shape and no change in color after drying. After adding water, it can quickly dissolve and restore the physical and chemical properties and biological activity of the original aqueous solution.
Third, since drying is carried out under vacuum conditions, it has a good protective effect on some easily oxidizable substances. Fourth, the moisture content of the product after lyophilization is very low, so that the stability of the product is improved, and the chance of being contaminated is reduced, which not only facilitates transportation but also prolongs the shelf life of the product.
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.
