Sizing Pressure-Relief Devices - AIChE

Positive-displacement pumps, compressors, and turbines require relief devices on the discharge side for deadhead protection. Segments of liquid-filled piping that have a high risk of overpressure due to thermal expansion (e.g., unloading lines) should have relief devices. Piping that can be overpressured due to process control failure

Chapter 9: Column Analysis and Design

- Failure occurs once the stress exceeds the elastic (yield point) limit of the material. • Long, slender columns fail by buckling – a function of the column's dimensions and its modulus of elasticity. - Buckling is the sudden uncontrolled lateral displacement of a column at …

Fracture-Critical Bridges – Simple Supports

May 28, 2013 · The Golden Gate – a fracture-critical bridge. The story of the I-5 collapse continues to evolve. Currently the focus seems to be on the fact that I-5 (not to mention I-35W) was classified as "fracture-critical", and the danger it and other fracture critical bridges pose.As there's a great deal of misinformation being spread about the nature of fracture-critical bridges, an explanation

Factors of Safety - Engineering ToolBox

Factors of Safety - FOS - are a part of engineering design and can for structural engineering typically be expressed as FOS = F fail / F allow (1). where . FOS = Factor of Safety. F fail = failure load (N, lb f) . F allow = allowable load (N, lb f) . Example - Structural Steel Column in a Building. Due to buckling the failure load of a steel column in a building is estimated to 10000 N.

Designing With Cylinders - Parker Hannifin

Rod Buckling Column failure or buckling of the rod may occur if the cylinder stroke is too long relative to the rod diameter. The exact ratio of rod length to rod diameter at which column failure will occur cannot be accurately calculated, but the "Column Strength" table in this manual shows suggested safe ratios for normal applications.

Causes of Hydraulic Pump Failures - Machinery Lubrication

A hydraulic pump failure can be caused by a number of factors. There are several different types of pumps available on the market, and each can have its own specific failure mode. Of course, certain failure modes are common to all types of pumps. Some of these failures can be caused by poor system design, using low-quality fluids and/or poor
