The suitability of a gasket material in a given application is dependent on a number of factors including chemical resistance, temperature and pressure capability, flange material and flange configuration and resistance to thermal cycling. Choosing the right material for the application can be a difficult and confusing task.

It is equally critical that the prescribed bolt loadings are sufficient to seat the gasket under the service conditions without overloading the gasket, bolting or flange. Consideration must be given to the minimum and maximum seating stress of the gasket as well as the relaxation of the gasket and studs and must allow for any variation in actual versus specified load through inaccuracies in bolt loading.

• Selection of gasket materials • Suitability of gasket materials for given applications • Selection criteria including flange material, gasket properties and approvals • Bolt torque calculations • Conversion factors

Novus SELECTTM calculates the required bolt stress and torque for a given application based on the material limits of both gaskets and bolts AND the effects of relaxation and assembly variation on the gasket stress. Its user friendly interface simplifies the calculation process for both standard and non-standard designs helping to ensure that the gasket will seal throughout its service life.

The program can also be modified by NovusTM to accommodate plant specific requirements.

The list of gaskets, bolt grade or lubricant type can be refined to include only those which are used on site, making the program ideal for plant based use.
