Rubber Expansion Joint Flexible Stainless Steel Connector
Products:Rubber Expansion Joint
A Rubber Expansion Joint is flexible connector fabricated of natural or synthetic elastomers,fluoroplastics and fabrics and, if necessary, metallic reinforcements used to absorb movements in a piping system while containing pressure and a medium running through it.
Advantages:
Reduced fatigue factor
Given the inherent characteristics of natural and synthetic elastomers, they are not subject to fatigue breakdown or embrittlement and prevent any electrolytic action because of the steel-rubber interface of joints and mating flanges.
Extraordinary resistance to abrasion and corrosion
A wide variety of natural, synthetic and special purpose elastomers and fabrics are available to the industry. Materials are treated and combined to meet a wide range of practical pressure/temperature operating conditions, corrosive attack, abrasion and erosion.
