Expansion joints for piping systems are flexible connectors, made out of PTFE, natural or synthetic elastomers, with combinations of rubber, fabric and metal reinforcement. Expansion joints installed into piping systems will help solve problems such as: Stresses - expansion joints absorb movement due to thermal expansion and contraction of pipes, wear, load stresses and settling of supports and foundations Misalignment - custom expansion joints can be manufactured with offsets to account for installation errors in pipe alignment, or for movement and settling over time Abrasion - with proprietary elastomers such as ABRA-LINE, abrasion can be significantly reduced compared to other rubber or metallic connectors Vibration - rubber expansion joints significantly reduce vibration when installed in proper locations and are not subject to metal fatigue failure Noise - transmission of sound is reduced as the expansion joint acts as a dampener and absorbs the noise levels Shock - effects of pressure surges, water hammer, or pump cavitation are resisted Corrosion - no metal to metal contact eliminating electrolysis between dissimilar metals Space - greatly reduced space required compared to expansion bends or lo

Metal Expansion Joints products need to conform to industry standards such as EJMA. Under the guidance of these standards, Garlock offers a complete range of metal expansion joints with the ability to design joints to individual customer requirements. Rigid engineering and quality control of Garlock metal expansion joints are what back up our assurance of long life and reliable service

We offers a series of standard types of Fabric Expansion Joints along with a numerous of special designs. Custom made Fabric Expansion Joints are available in all sizes and shapes for any application – from single bellows for ventilating systems to highly advanced multilayer expansion joints for gas turbine exhaust (see below). The common factor is always the craftsmanship, the use of superior materials and knowing their forces and limitations.
