TBM (Tunnel Boring Machine) equipment operates in extreme environments where high-speed rotation, high-pressure slurry, and abrasive particles coexist. Severe wear and impact damage repeatedly occur in areas such as behind the disc cutter, slurry pipelines, and the chain, guide, and segment of the roadheader.

Yuil Tech provides the following customized wear-resistant solutions:

Main Applications and Processes

6–8 inch curved and straight slurry discharge pipes

Severe wear caused by high-velocity (tens of m/s) fluid flow and impact angles

Manual Cr-series hardfacing welding often causes layer detachment

Resolved by combining CCO pipes with manual reinforcement welding

Applied 3-split insert-type wear-resistant structure or ceramic/CrC buffer layer for curved sections

Roadheader Wear Components

Chains, guides, and segments are exposed to heavy loads and repeated impacts

Applied composite metal hardfacing or replaceable domestic composite components
