Heat exchangers experience significant thermal expansion and contraction as hot and cold fluids transfer energy. This thermal cycling can cause standard bolts to loosen or experience fatigue failure.
SRG Fasteners supplies specialized alloy and stainless steel fasteners designed with specific coefficients of thermal expansion to match the flange material, ensuring a consistent seal across all operating temperatures.
Frequently Asked Questions
How do you handle thermal expansion in bolted joints?
We match the fastener material's coefficient of thermal expansion to the flange material. In extreme cases, Belleville (conical spring) washers are used to maintain tension as the joint expands and contracts.
