PRODUCT
INTRODUCTION
TS B90 tail-seal brush is specifically designed for the sealing of Tunnel Boring Machines. It is capable of reliably withstand the sealing pressure required for construction at depths of 50 meters. However, it is important to note that this capability depends on several factors, including but not limited to: proper filling rate of the tail seal grease, precise design of the spacing between the tail brush rows, and adherence to the specific technical characteristics of tail-seal grease. These considerations are crucial for ensuring optimal performance and durability of the tail seal brush under various operational conditions.
ADVANTAGES
TS B90 offers numerous advantages, including:
• Excellent compressive strength
• Outstanding wear resistance
• Excellent toughness and elasticity
• Superior corrosion resistance
TS B90 is perfectly compatible with HERSHENG’s series of Tail-seal greases. When used together, they ensure long-lasting sealing and protection throughout the entire construction period, effectively preventing leaks.
