Testing and Processing # 1979 Brigthon
The influence of processing variables on long term strength of pipe materials and on long term resistance values to internal pressure of pipes have been studied by the use of axial creep and creep rupture tests and standard pressure tests. The design criteria for a pipe as we1 l as the choise of the dimensioning value of circunferential stress have been discussed
