Its types are divided into centrifugally cast composite ceramic elbows, patch wear-resistant tubes and spot welding card-type wear-resistant tubes. What are the properties of these three types of wear-resistant elbows? Wear-resistant elbows can be divided into the following categories according to different connection methods and structures:
The wear-resistant steel used for wear-resistant elbows is used as the basic material and can be used in pipeline systems in various situations. Such as abrasive wear, corrosion wear, erosion wear, impact wear, etc. Since it is a wear-resistant elbow, The characteristic is wear resistance, which can be confirmed by the actual operation of the industry. Because the running resistance is small, the running cost can also be reduced. In general, wear-resistant elbows are resistant to acid and alkali and seawater corrosion, and can also be well anti-scale, thermal stability is also very prominent, can be long-term between -50 ~ 900 degrees normal operation.
Because of its long service life and reasonable price, compared with wear-resistant alloy pipes, its engineering cost has been reduced by 20%, and the overall handling costs, installation costs and operating costs have been reduced at the same time. The wear-resistant elbow is light in weight and has good weldability, so whether it is welded or fast-connected, it is very convenient to install.
In recent decades, the development and application of low and medium alloy wear-resistant steels have developed rapidly.Since these steels have good wear resistance and toughness, the production process is simple, the comprehensive economy is reasonable, and it is suitable for many working conditions. And it is welcomed by users. This also makes the application of thick-walled wear-resistant alloy elbows more extensive and the cost is more and more low. Wear-resistant elbows have a wear resistance that is unmatched by traditional elbows, so they are widely used in various There are many types of wear-resistant elbows in pipeline connection, and wear-resistant elbows are favored by the industry more than traditional elbows, and the continuous development and progress of technology and the continuous cost reduction of wear-resistant elbows make wear-resistant elbows The industry position of the head is constantly being stabilized.
Characteristics of wear-resistant elbow fittings:
1, temperature and pressure resistance, good flexibility, heat resistance, its performance is higher than other plastic pipes. Easy installation, good thermal conductivity, suitable for floor heating systems, recyclability.
2. The wear-resistant elbow pipe has its excellent impact strength, hot melt welding and mechanical connection, which is superior to the thermal conductivity of PB-PP-R.
