The stamping elbow

Stamping elbow is a weak link in piping pipeline reliability mainly determined by the working ability of the stamping elbow. Stamping elbow of the ability to work and its stress state. The calculation and field of the measured tube working stress, found that the stamping elbow arc starting point particularly sensitive to external load, the removal of internal pressure and dead weight load main piping is metal pipe thermal expansion, in the process of starting work steam-water piping vibration and anomaly caused by the additional external load, etc
