Material conveying wear-resistant pipes are the bloodline of industrial production, and ensuring the service life of pipes is a prerequisite for safe and efficient production. The wear of straight pipes is generally much smaller than that of bent pipes. Therefore, the wear of the elbow is mainly considered in the pneumatic conveying. The conveyed materials are abrasive materials such as iron powder. Using an ordinary steel elbow, continuous conveying for 2 hours, the elbow will be worn through.
The main factors of wear caused by material impact or friction on the inner wall of the pipe are as follows:
(1) Transport medium: including particle size and shape, concentration, hardness, moisture, crushing rate and adhesion, etc.
(2) Pipe material: Including the material and metal structure of the delivery pipe, hardness, inner diameter, surface treatment, etc.
(3) Delivery conditions: Including conveying air velocity, temperature and flow state, etc.
In actual transportation, the influence of the above factors on wear does not exist singly, but appears comprehensively. Therefore, even if it is the same material, the wear-resistant pipeline-ceramic composite pipe of the same material is used, and the degree of wear is different due to different transportation conditions.
The product series produced by the company include: wear-resistant ceramic pipes, wear-resistant ceramic composite liners, wear-resistant ceramic drum rubber coatings, ceramic steel plate composite liners, hopper silos, integrated equipment lining ceramics, engineering machinery concrete ceramic pump pipes and other products , It is widely used in more than 30 large and medium-sized cities and large and medium-sized enterprises in China, and exported to many countries around the world, and is widely praised.
The wear-resistant ceramic pipes produced by the company make full use of the steel pipe's high strength, good toughness, impact resistance, good welding performance, and the high hardness, high wear resistance, corrosion resistance, and heat resistance of the corundum porcelain, which overcomes the low hardness of the steel pipe. Defects such as poor wear resistance and poor ceramic toughness. Therefore, the composite pipe has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical shock resistance and thermal shock resistance, and good weldability. It is an ideal wear resistance and corrosion resistance for conveying particulate materials, grinding, and corrosive media. pipeline.
