Non-Metallic Pipe Joints

To help compensate for compressive and elongating movements in a piping system, an elastomeric expansion joint is often beneficial. This is a flexible connector typically constructed of rubber and fabric. There are several benefits to using an expansion joint, including dampening sound and lessening vibration while allowing for angular and torsional movement. In addition, expansion joints prolong life in bearings and oil seals.
For the most effective use and life, retaining rings are always recommended with expansion joints. Control units may also be needed to prevent over-elongation. Atlantech can provide elastomeric expansion joints in any range of materials and arch configurations to ensure your piping systems operate at their most efficient.

Garlock Garflex® 8100 Expansion Joints

Garlock Garflex® 8100 Expansion Joints

Garflex® expansion joints feature rugged yet flexible nylon cord reinforcement in a molded, spherical bellows design that ensures an exceptional burst pressure rating. The streamlined flowing arch design reduces turbulence and allows smooth, quiet flow-no need to fill the arch and restrict its movement.

Garlock Style Guardian® 200-1 Expansion Joints

Garlock Style Guardian® 200-1 Expansion Joints

Garlock Guardian® 200 expansion joints consist of a chemically-resistant FEP* liner mechanically bonded to an abrupt arch. A chlorobutyl cover and blue protectant coating add resistance to environmental effects. (Alternate cover materials available.)


Garlock Style 206EZ Expansion Joints and Retaining Rings

Garlock Style 206EZ Expansion Joints and Retaining Rings

EZ-FLO® expansion joints contain a single wide flowing arch, eliminating the need for filled arches on slurry services. Garlock EZ-FLO® expansion joints have successfully served all major industries, including pulp and paper, steel, waste and water, HVAC, power generation, chemical, petrochemical and marine.
The self-flushing design eliminates media buildup and reduces fluid turbulence. High pressure and vacuum-resistance ensures longer life and reduces inventory requirements. The lightweight design installs easily and costs less to ship.

Garlock Style 204 and 204HP Expansion Joints and Retaining Rings

Garlock Style 204 and 204HP Expansion Joints and Retaining Rings

Styles 204 and 204HP spool-type expansion joints can be constructed as single- or multiple-arch types. They connect pipe flanges in concentric or eccentric tapers, to join piping of unequal diameters. Fully lab- and field-tested for long life and exceptional reliability the seamless flange face eliminates need for gaskets.
High pressure and vacuum-resistance increases safety and ensures suitability for wide range of applications. Styles 204 and 204HP can be custom-designed for greater movement capability and easier installation. A variety of elastomer and fabric combinations meet the demands of temperature, pressure and media.
