Split arc labyrinth steam seal segments (most widely adopted for small turbines)
Integral circular steam seal assemblies
Single-piece labyrinth seal strips
Optimized high-efficiency seal retrofit components
Spring-backed steam seal segments
Applicable Materials
42CrMo, 25Cr2MoV, 12Cr1MoV, stainless steel, cast alloy steel and other heat-resistant materials, matched according to operating temperature, pressure and medium conditions.
