Bimetallic cylinder liner is a special component composed of two different materials of pipe walls, usually consisting of a flexible stainless steel inner layer and an outer wear-resistant material outer layer. This design makes it have good application effects in some special environments.

Its main uses include: in situations where high temperature resistance, wear resistance, or increased friction coefficient are required, it can play a significant role; At the same time, it also has good performance in absorbing vibrations and large impacts; In addition, it also has excellent corrosion resistance and is suitable for various chemical environments. These characteristics make bimetallic cylinders widely used in the upper and lower support attachments of construction machinery (such as excavation buckets). The widely used bimetallic composite pipes on excavators are embedded alloy steel seamless steel pipes with circular rings, mainly used for transporting slurry mixtures (pressurized materials). From this, it can be seen that this is a highly adaptable and feature rich component that can provide excellent solutions in many situations.
