Manage Thermal Expansion, Vibration, and Sealing with FlexTec Expansion Joints

Fabric and metal expansion joint solutions for petrochemical, cement, aluminum, iron-steel, and power generation industries. Reliability under high temperature and pressure, low maintenance costs, and extended equipment lifespan.

Expansion Joint Applications

FlexTec expansion joint solutions tailored to the specific needs of each industry

Petrochemical & Gas

ATEX-Compliant Solutions

Fabric expansion joints provide gas flow management and thermal expansion control in ATEX zones. Metal expansion joints offer durability and sealing in high-pressure lines.

  • Refinery and storage tank lines
  • Exhaust/flue ducts
  • High-temperature and explosive environments
Cement

Kiln & Clinker Lines

Fabric expansion joints provide hot gas and particulate control in raw mill, rotary kiln, clinker cooler, and heating units; metal expansion joints manage expansion/vibration damping in combustion units and exhaust outlets.

  • Dust and particulate sealing
  • High-temperature resistance
  • Extended system lifespan
Aluminum

Smelting and Ducts

Thermal expansion in smelting and auxiliary facilities is absorbed by fabric/metal expansion joints, reducing pipe deformation and unplanned downtime risks.

  • Furnace outlet lines and ducts
  • Auxiliary facility connections
  • Stable operation at high temperatures
Iron-Steel

Furnace, Rolling Mill, Heat Treatment

Fabric expansion joints balance gas flow and expansion; metal expansion joints reduce vibration and mechanical stress in pipelines, exhaust, and combustion units.

  • Reliability at high temperatures
  • Particulate control
  • Expansion management
Power Generation

Boiler, HRSG, and FGD

FlexTec expansion joint solutions for critical areas between boiler-FGD in coal plants and turbine-HRSG in natural gas combined cycle plants.

  • Metal expansion joints: high pressure/temperature
  • Fabric expansion joints: flexible transitions, sealing
  • Long lifespan and low maintenance
Glass & Fiberglass

Smelting and Annealing

Fabric expansion joints manage expansion/sealing in smelting furnaces, annealing lines, and hot air ducts; metal expansion joints provide high-temperature and pressure resistance.

  • Furnace exhaust/flue connections
  • Hot air/cooling ducts
Paper & Pulp

Drying and Steam Lines

Fabric expansion joints in drying hoods, steam lines, and VOC exhausts; metal expansion joints in vibration-prone lines.

  • Steam/condensate outlets
  • Hood exhaust lines
Waste Incineration & WtE

Combustion and Recovery

High-temperature resistant fabric expansion joints in combustion chamber outlets and pre-FGD lines; metal expansion joints in turbine/generator exhausts.

  • Gasification/combustion exhausts
  • Heat recovery ducts
Marine & Shipbuilding

Generator and Main Engine

Metal expansion joints in generator and main engine exhausts; fabric expansion joints in HVAC and flue ducts.

  • SCR/EGCS (scrubber) connections
  • Engine room exhausts
Mining & Ore

Dust Collectors and Furnaces

Fabric expansion joints in dust collectors and furnace exhausts; metal expansion joints in pressurized process pipes.

  • Filter transitions
  • Drying furnace ducts
Chemical & Fertilizer

Reactor and Absorption

Corrosion-resistant metal expansion joints in ammonia/urea, acid, and solvent lines; fabric expansion joints in gas scrubbing and exhaust lines.

  • Reactor connections
  • Absorption/stripper exhausts
LNG & Cryogenic

Low-Temperature Applications

Metal expansion joints resistant to low-temperature shocks and fatigue; fabric expansion joints in auxiliary air lines.

  • Cold box pipe connections
  • Loading/unloading lines
