The four design basis to consider are 1.) Materials 2.) Physical attributes 3.) Loading conditions 4.) Environmental factors

Power is time rate of performing work.

The Maximum Shear Theory states that pipe failure happens and the maximum shear stress exceeds shear stress at yield point ...Continue Reading

The Maximum Principle Theory states that yielding happens and the magnitude of 3 perpendicular stresses exceed yield point strength of ...Continue Reading

The over stress theory establishes the point at which failure will occur under combined loading. This theory describes the strength ...Continue Reading

Failure by fatigue occurs due to cyclic loading. If a small crack develops it grows after each cycle an results ...Continue Reading

Failure by fracture occurs without undergoing yielding.

The second critical value of pipe sizing criteria is adjusted volumetric flow rates at the design point of the network.

The weight of pipes, valves, flanges, fittings, media and insulation would be classified as internal forces.

Deformation is when slip action of grains at sub elevated temperatures occur or elevated temperature, slip grains recrystallized lending to ...Continue Reading

Principal Stress Theory and Shear Stress Theory.

Modes of failure include stress, fracture and fatigue.

The “hot” conditions refer to that point in the operating cycle when the piping reaches its final operating condition.

The cold state of the piping system is initial and ambient.

The hot state of a piping system is full and operational.

Factors of high energy piping systems include: temperature, movements, complexity, multi-facet and volatile.

Types of treatment facilities are water and sewage.

“Balance of Plant” refers to the components of a piping system not included in the primary system. Examples are blowers, ...Continue Reading
