What is Expansion Joint Nosing or Header Material EMSEAL

31012017· Expansion joint nosing or header material is a resin (usually polyurethane based) with aggregate additives that is mixed and poured in the field into blockouts on each side of a structural expansion joint gap The material when cured is less rigid than the adjacent concrete substrate and as a result is more forgiving of traffic impact and suddenly applied vehicle loads A high performance nosingAn expansion joint is a speciallydesigned component of compact dimensions that allows differential movement between two adjacent components and maintains the pressure envelope Sometimes a packed joint is used, (see Mechanical Design of Heat Exchangers , Figure 1 , for a packed floating head) but these are limited to low pressure and low severity dutyEXPANSION JOINTSThere two types of Expansion Joint, first the thin joint And with reinforcement elements, limits expansion stresses The Toroidal thin joint is used less often, difficult to manufacture 10/2/2014 9Expansion Joints in Heat Exchangers
