Are you looking to enhance the performance of your chemical tower? The choice of pall rings can make all the difference!   - Chemshun  Ceramic Pall Rings: If you prioritize durability and resistance to chemical corrosion, then ceramic pall rings are an ideal choice for you!  Their excellent thermal stability and low-pressure drop characteristics ensure efficient mass transfer in various chemical processes.   - Plastic Pall Rings: Seeking a cost-effective yet efficient solution? Plastic pall rings are your go-to option!  These lightweight rings offer excellent resistance to acids and alkalis, ensuring longevity and reliability. Plus, their low-pressure drop allows for increased contact surface area, making them suitable for large-scale applications.   -   Metallic Pall Rings: If you desire optimum mechanical strength and high-temperature resistance, metallic pall rings are the way to go! Their sturdy construction withstands extreme process conditions, m...

The Reason of Ceramic lined pipes wear damage ?

Wear resistant ceramics are composed of equipment elbows and some parts. Inventing this thing in the field of mine transportation can serve people well and reduce some costs. It has good wear resistance, which can be said to be one of its main characteristics. In the case of erosion and wear, the wear resistance of wear-resistant ceramics is dozens of times that of ordinary steel, which ensures the life of the pipeline; because of its good impact resistance, because most of the transportation is some ore and coal, only the anti-corrosion Only when the impact is good can it resist. This may be the reason why everyone chooses pipelines. 1. Wear analysis and causes of wear-resistant ceramics 1. During the transportation process, the air flow velocity will wear the outer arc tube wall of the wear-resistant elbow relatively. Under the same conditions, the wall wear can be reduced to a great extent by reducing the material impact velocity or changing the material impact angle. Because the w...

How to improve the impact resistance of abrasion resistant ceramic lining

  Abrasion resistant ceramic liners have solved the problem of wear for heavy wear industries such as cement, steel, mining, lithium batteries, and metallurgy. However, in the minds of many manufacturers, liners are also labeled as brittle and not impact-resistant. How about the impact resistance of ceramics? How can we improve the impact resistance? The main material of the wear resistant ceramic lining plate we usually call is alumina, its fracture toughness KΙC ≥ 4.8MPa?m1/2, and bending strength ≥ 290MPa. Compared with metal materials such as steel, the impact resistance is indeed inferior. However, through some special processes, the impact resistance of the wear-resistant ceramic lining can be greatly improved. 1. Surface design with spherical protrusions: The unique mechanical properties of spherical protrusions can evenly disperse the impact force on the liner, reducing the possibility of the liner being broken by impact. It is a relatively common method to improve the imp...
