Description
Custom Steam Seals for Small & Medium Power Steam Turbines
Product Overview

Labyrinth steam seals are critical static sealing components for small-power industrial steam turbines. Installed between rotors and stators, they form multi-stage labyrinth clearance to restrain steam leakage, reduce energy loss, improve unit thermal efficiency and guarantee stable safe operation.

We provide fully customized steam seal solutions specially tailored for small-power steam turbines including back-pressure turbines, condensing turbines, waste heat turbines, generator drive turbines, and mechanical drive turbines.

Product Types
  • 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.

Manufacturing Process
  • Drawing verification & technical scheme confirmation
  • Forging / casting blank preparation
  • Normalizing & tempering heat treatment
  • Rough CNC machining
  • Stress relief annealing
  • Precision finish machining of labyrinth teeth, mounting surfaces and bolt holes
  • Optional: Stellite alloy hardfacing on sealing tooth tips
  • Dimensional inspection, concentricity & flatness testing
  • NDT inspection (PT/MT/UT as required)
  • Deburring, cleaning and anti-rust packaging
Core Advantages
Customized Design

Optimized labyrinth tooth structure and clearance design for small-power turbines with frequent load fluctuation and compact assembly space.

High Machining Precision

Precision CNC machining ensures uniform labyrinth tooth height, consistent spacing, and precise installation dimensions.

Material & Surface Options

Proper base material selection with optional Stellite hardfacing for enhanced high-temperature erosion and wear resistance.

Flexible Production

Suitable for small-batch customized orders with short lead times for urgent maintenance requirements.

Quality Control

Complete documentation including material certificates, heat treatment records, and inspection reports complying with industrial standards.

Application Scope
  • Small condensing / back-pressure power generation steam turbines
  • Waste heat recovery small turbines
  • Mechanical drive turbines (pump, fan, compressor drive)
  • Cogeneration industrial turbines used in chemical, textile, paper, metallurgy industries
