Product Description
The main principle of the concrete pump elbow lining ceramic is to use high-strength ceramic materials to protect the inner wall of the pipeline, and at the same time, the pipeline is optimized by the principle of dynamic mechanics to minimize the wear of the material to the pipeline. Concrete pump trucks are widely used in modern construction. The pump pipes are responsible for many important tasks such as concrete mixing and transportation. The pump pipe boom pipes are severely worn under the high pressure of gravel and concrete slurry and require frequent replacement and maintenance. Concrete pump elbow pipes are generally at a height of more than ten meters or higher, which is difficult to replace. The ceramic pipes of concrete pumps have a long service life and are easy to replace. It can completely solve the problem of frequent replacement of ordinary pump truck pipes due to rapid wear and tear. Grinding ceramic pump truck pipelines is currently the choice of most concrete pump trucks.
Company Introduction
Hunan Yibeinuo New Material Co., Ltd. mainly produces wear-resistant ceramic-related products. Ceramic pump pipe is one of the main products applied to the concrete industry of construction machinery. It also includes cutting rings for glass plates, concrete pistons, concrete cylinders, S tubes, tube clamps, rubber tubes, rubber rings,s and other concrete pump accessories.
Working principle
Our company has developed a super wear-resistant ceramic concrete pump elbow based on full research on the wear mechanism of various pump truck pipelines under different operating conditions. The ceramic is designed according to the arc structure of the pump truck elbow, and the ceramic adopts isostatic pressure. Process, use high-strength wear-resistant ceramics to protect the inner wall of the pipeline to reduce the wear of the pipeline.
The wear-resistant ceramic pump truck pipeline uses alumina as the main material, and the hardness can reach above HRA90. The concrete ceramic pump truck pipeline has high hardness and strong toughness, which is very suitable for the working environment of the concrete pump truck.

The advantages of concrete pump ceramic elbow
1. Long service life and large conveying capacity: The ultra-high hardness and toughness make the wear-resistant ceramic pump truck pipeline have strong wear resistance. The concrete ceramic pump pipeline has increased the conveying capacity and service life of the concrete by 10 compared with ordinary metal pipelines. Times more.
2. Lightweight and easy to replace: the pump truck pipeline is installed high in the sky, which is difficult to replace and has a high-risk factor. The weight of the ceramic concrete pump truck pipeline is 20%-30% lighter than the metal pipeline of the same specification, which greatly reduces the replacement. Difficulty and replacement cost.
3. The inner wall is smooth and does not block the material: The ceramic material has high smoothness originally, and the smoothness will not decrease after abrasion, which greatly reduces the blocking phenomenon.
4. Good compression resistance, safe and reliable: The pipeline is made of 20# seamless steel pipe stamping, with good sealing performance, and the ceramic compressive strength is 50MPa. It does not have the problem of pipe bursting.
5. Save cost, manpower, and material resources: The wear-resistant ceramic pump truck has a long service life, is lightweight, and has no material blocking. This greatly reduces the number of maintenance of the pump truck pipeline, and the maintenance and replacement are less difficult, saving a lot of maintenance costs.
