Custom-manufactured rubber expansion joints alleviate the stresses induced by thermal expansion and contraction within pipelines. Our rubber expansion joints are offered in both single- and multi-arch configurations and are custom-engineered to meet your specific application requirements. Available options include PTFE-lined, concentric reducing, eccentric reducing, filled arch, lightweight, and offset designs. With a diverse selection of elastomers, H.S. White rubber expansion joints can be engineered to function at pressures of up to 200 psi and temperatures reaching 500°F, with sizes ranging from 1/2” to 144”.
We are here to help you find the optimal design for your application.
