What is the Maximum Shear Theory when referring to operating outside the limits in the piping system?
July 15, 2014
The Maximum Shear Theory states that pipe failure happens and the maximum shear stress exceeds shear stress at yield point of tensile test. (ASME B31.3)
Read MoreWhat is the Maximum Principle Theory when refering to operating outside the limits in the the piping system?
The Maximum Principle Theory states that yielding happens and the magnitude of 3 perpendicular stresses exceed yield point strength of material.

When does failure by over stress occur in the piping system?
The over stress theory establishes the point at which failure will occur under combined loading. This theory describes the strength of the piping system including the maximum principle stress and the maximum shear stress.
When does failure by fatigue occur in the piping system?
Failure by fatigue occurs due to cyclic loading. If a small crack develops it grows after each cycle an results in failure.

When does failure by fracture occur in the piping system?
Failure by fracture occurs without undergoing yielding.

What is the second critical value of piping size criteria?
July 14, 2014
The second critical value of pipe sizing criteria is adjusted volumetric flow rates at the design point of the network.
Read MoreWhat would be classified as an internal force?
July 2, 2014
The weight of pipes, valves, flanges, fittings, media and insulation would be classified as internal forces.

What is deformation mode of failure in a piping system?
Deformation is when slip action of grains at sub elevated temperatures occur or elevated temperature, slip grains recrystallized lending to yield.

What is the “hot” condition of a piping system?
June 23, 2014
The “hot” conditions refer to that point in the operating cycle when the piping reaches its final operating condition.
