A large amount of oil and gas production needs to be followed by optimal pipeline maintenance. Most cases pipe leaks are sudden in nature that able cause losses over a long period time. The consisting sand particles increase erosion rate, especially at the elbows. Cases prevented through routine inspections based on accurate rate predictions. This study aims predict elbow piping systems using c...

The complex properties (mechanical, microstructure, and electrochemical) of controllable rolling X70 steel pipes the main gas pipeline with a diameter 1420 mm after an operation for 20 years emergency reserve pipe similar period storage were studied. Taking into account specified heterogeneity caused by technological effect on rolling, it is difficult to draw unequivocal conclusions about opera...

generaly pressure vessels should withstand internal and external pressures in the form of static or periodic stresses. if the application of such a vessel requires the lowest possible weight, the fracture mechanics approach may be considened in design procedure in order to obtain the minimum wall thickness. in this work the thickness of the vessel wall was determined using k values and smallest...
