Conventional gasketed-flanged pipe joints are widely used in the oil and gas and process industries for connecting pipes to pipes and pipes to other pressure equipment. For bolted flange joints, the two main concerns are joint strength and sealing capability. Currently available design methods and codes address only the structural strength of the flange joint under internal pressure only and do not fully consider the effect of sealing capability of the joints under transient thermal loading.
A flange leak results in loss of product and energy, and sometimes with disastrous consequences. No plant operator wants a leak of toxic or hazardous material that can harm humans and the environment. Using the right types of gasket will help to achieve a reliable seal to prevent the leak from the flange joints
