Expansion Joints and Metal Hose Assemblies for Pulp and Paper Industry

Our expansion joints are designed for the harsh operating environments found in pulp mills, paper machines, recovery boilers, digesters, and chemical processing systems. Built with durable materials and engineered for long-term reliability, they help maintain system integrity while reducing maintenance and unplanned downtime, inspiring trust in their performance.

Our expansion joint solutions are designed to:

  • Absorb thermal expansion and contraction
  • Isolate vibration from pumps, turbines, and rotating equipment
  • Reduce stress on piping systems and process vessels
  • Accommodate axial, lateral, and angular movement
  • Improve system reliability and extend equipment life
  • Boiler air systems
  • Scrubber inlet and outlet ducts

These solutions support critical process areas, including steam distribution systems, flue gas ducts, chemical processing lines, and cooling water infrastructure. They are designed for straightforward installation and compatibility with standard piping configurations.

Types of Expansion Joints Used in Pulp Mills

Metallic Expansion Joints

Our metal expansion joints feature multi-ply stainless steel bellows designed to withstand high temperatures, pressure, and cyclic movement. They are commonly used in steam systems, turbine exhaust connections, and high-temperature process piping.
Constructed from corrosion-resistant alloys such as stainless steel and high-nickel materials, metallic joints provide exceptional durability in demanding pulp mill environments, giving confidence in their long-term performance.

Typical applications include:

  • High-pressure steam piping
  • Digester piping systems
  • Boiler connections
  • Turbine steam lines
  • Chemical recovery systems

Fabric Expansion Joints

Our fabric expansion joints are flexible multi-layer connectors used in low-pressure air and gas ducting systems. These joints accommodate large movements while providing excellent resistance to corrosive gases and high temperatures.

Fabric expansion joints are commonly installed in flue gas systems associated with boilers, lime kilns, and emission control equipment.
Typical applications include:

  • Recovery boiler flue gas ducts
  • Lime kiln exhaust systems

Rubber Expansion Joints

Our rubber expansion joints are typically installed in liquid piping systems where vibration, noise, and pipe movement need to be controlled. Their flexible elastomer construction allows them to absorb movement and protect pumps and piping from mechanical stress.
Typical applications:

  • Cooling water piping
  • Process water systems
  • Pump suction and discharge connections
  • White water circulation systems

PTFE Expansion Joints

Our PTFE expansion joints are constructed from polytetrafluoroethylene (PTFE) and supporting structural components designed to withstand corrosive chemical environments commonly found in pulp and paper processing.

Typical applications:

  • Chlorine dioxide systems
  • Bleaching chemical lines
  • Acid transfer piping
  • Chemical dosing systems

Slip-Type Expansion Joints

Our slip-type expansion joints (also called packed expansion joints) are designed with telescoping pipe sections that allow axial movement while maintaining a pressure seal. They are commonly used in steam and high-temperature piping systems in industrial plants such as pulp and paper mills.

Typical applications:

  • Long steam distribution lines
  • Utility piping networks
  • High-temperature steam systems

Metal Hose Assemblies

Metal hoses are widely used in pulp and paper mills where high-temperature steam, corrosive chemicals, vibration, and thermal movement make rigid piping impractical. Our corrugated stainless steel hoses with external braid reinforcement provide flexible, pressure-tight connections that protect piping and equipment.

Typical applications:

  • Paper machine dryer steam lines
  • Boiler and condensate piping
  • Chemical processing systems
  • Pump and compressor connections
  • High-temperature fluid transfer lines
