A dual alloy cutting ring, also known as a dual alloy wear plate or dual alloy cutting edge, is a specialized component used in the pipeline system of concrete pump trucks. It is designed to provide enhanced wear resistance and durability compared to traditional cutting rings.

A dual alloy cutting ring is typically composed of two different alloy materials:

1:Outer Alloy: The outer alloy is usually a high-hardness and wear-resistant material, such as steel. It offers exceptional resistance to wear and can withstand the impact and abrasion caused by concrete particles. The outer alloy serves as the primary wear-resistant layer of the cutting ring.

2:Inner Alloy: The inner alloy is typically a material with good toughness and elasticity, such as rubber or polyurethane. It provides sealing performance and flexibility to the cutting ring, ensuring a tight connection and accommodating the movement and deformation of the pipeline system during operation.

By combining a high-hardness outer alloy with a resilient inner alloy, the dual alloy cutting ring offers prolonged service life while maintaining excellent sealing performance and flexibility. This extends the lifespan of the cutting ring and reduces the frequency of maintenance and replacement.

Dual alloy cutting rings possess similar attributes to other cutting rings, including excellent sealing performance, wear resistance, and adaptability. They are widely used in concrete pump truck pipeline systems to ensure reliable and efficient concrete pumping operations.
