Product Description Backpack lined pipe elbows are also called reinforced elbows, and the wear resistant parts welded at the parts where the impact and wear of the elbows are more serious are called backpacks. The wear resistant ceramic backpack elbow is based on the Wear resistant ceramic elbow, and a layer of antiwear design is added. The special ceramic is pasted on the inner wall of the pipeline with a high temperature-resistant inorganic adhesive, and after being heated and cured, it forms a solid antiwear design. Therefore, the Wear resistant ceramic backpack elbow realizes double-layer wear resistance, and the reinforced or double layer Wear resistant lining pipes are mainly suitable for working conditions with serious wear. Industry application Wear resistant lined pipes are often used in pneumatic conveying, especially in the process of pneumatic conveying, the bends of the pipeline are easy to wear and tear. The backpack-type wear resistant elbow (reinforced wear resistant elbow) produced and designed by Iberno can more effectively improve the Wear resistant life of the pipeline. It is processed by using Wear resistant materials and ordinary metal pipelines or finished elbows to improve its durability. Improve the grinding performance, change the shape and structure of its surface, make a special elbow with a backpack (double layer) shape, increase the thickness of the elbow scour part improve the wear resistance of the scour part, and generally improve the lining pipe service life. Ceramic backpack wear resistant elbows are generally used in coal powder conveying systems and dust removal systems in thermal power, steel, chemical, smelting, cement, etc.

Laminated magnets are a type of magnetic material that is used in various industries, including automotive, aerospace, medical, and electronics. The magnets are made of multiple layers of thin magnetic sheets or laminations that are stacked together to create a stronger magnetic force. Advantages of Laminated Magnet The primary advantage of laminated magnets is their ability to reduce the eddy current losses in the magnetic material. Eddy currents are circular currents that are induced in the magnetic material when it is exposed to a changing magnetic field. These currents generate heat and cause energy losses, which can be significant in high-speed rotational applications like electric motors, generators, and turbines. There are many custom magnet manufacturers, but we are one of the best choices for you.

circular halbach array are a special arrangement of permanent magnets that creates a strong and focused magnetic field on one side while minimizing the field on the other side.
