<br/><br/> Flanged conical pipe reducer shells are studied . Due to the existence of this type of flanged connection local bending takes place at the assumed rigid locations that causes discontinuity local bending takes place at the assumed rigid locations that causes discontinuity stresses . Plastic instability pressure considered as burst pressure is obtained by the use of finite element method
