What does the Maximum Shear Stress Theory state?

September 18, 2015

The maximum shear stress theory states that failure of a piping component occurs when the maximum shear stress exceeds the shear stress at the yield point in a tensile test.

Out of the Six Theories of Failure, which are the 2 that are the most widely used?

September 17, 2015

The Maximum Principle Stress Theory and Maximum Shear Stress Theory

What does the Maximum Principle Stress Theory state?

This theory states that yielding in a piping component occurs when the magnitude of any of the three mutually perpendicular principal stresses exceeds the yield strength of the material.

What are the 5 modes of failure of piping design?

September 16, 2015

Failure by general yielding, yielding at sub-elevated temperature, brittle fractures, and fatigue.

What is the purpose of Stress Analysis?

Stress analysis ensures the safety of piping and piping components, safety of connected equipment and supporting structure, and that piping deflections are within limits.

What is Stress Analysis?

September 11, 2015

A term applied to calculations, which address the static and dynamic loading, resulting from the effects of gravity, temperature changes, internal pressures, fluid flow, seismic activity, and any external loads.

What is the Stress-Strain curve?

It is a visual representation of the effects of various loading conditions on a piping system between stress and strain.

What are the 5 majority causes of failures (after flexibility analysis) of a system?

Vibration, thermal bowing, creep, thermal fatigue, and steam/water.

What are the effects of excessive flexibility?

September 9, 2015

Excessive flexibility causes an increase in material costs, pressure drops, and loss of pump efficiency.

What are the methods of incorporating flexibility in a piping arrangement?

Using flexible piping with bends and turns, use of expansion loops between fixed locations, or use of expansion joints between two anchor points of a pipe run.

What is the purpose of flexibility analysis?

September 4, 2015

Flexibility analysis assures that there is not any overstress or fatigue, leakage at joints or distortions are piping connections or terminals.

What is the objective of having flexibility within a piping system?

To produce neither excessive stress within the configuration and limit excessive end reaction at the piping terminal.

What are some adverse operating conditions of a piping system?

September 3, 2015

Fluctuating temperatures, changes in pressure, and modification in flow rate.

PT&P Partners with University of Houston's College of Technology

July 25, 2013

July 25, 2013, Houston, TX – In an effort to expand our community presence and help students expand their education and interests, Piping Technology & Products is excited to announce our new partnership with the University of Houston’s College of Technology. As the goal of the UH College of Technology is to provide the highest quality education in fields such as mechanical engineering, construction management, and computer engineering, so is Piping Technology’s goal to help educate people interested in these fields as a public service to the community. As online courses become the norm for many colleges these days, PT&P realized this would be the perfect way to combine our thirty five years of manufacturing experience  with the UH College of Technology’s established reputation.

University of Houston - College of TechnologyThis new online course is titled “Piping Design & Analysis Influence on Pipe Support Selection andDesign”. The course covers the following topics: piping design and how it effects the overall configuration on preliminary piping design, initial layout, the total system, introduction to pipe stress analysis, detailed piping design, and how all of this influences pipe support and pipe hanger design. This is a self-paced course consisting of eight sections. The student will have four weeks to complete the eight sessions, which must be taken in sequential order. This is an online course only, with no classroom meetings required.

This course is approved for 8 PDH hours for Texas Professional Engineers.

The College of Technology at the University of Houston was established over seventy years ago and offers numerous fully accredited undergraduate courses and masters’ degrees through three departments: Engineering Technology, Human Development and Consumer Sciences, Information and Logistics Technology.

Piping Technology & Products, Inc. is headquartered in Houston, TX and began business in 1978. PT&P and its wholly owned subsidiaries (U.S. Bellows, Inc., Sweco Fab, Inc., Pipe Shields, Inc., and Fronek Anchor/Darling Enterprises, Inc.) offer a wide range of engineered products and services for various industries and applications.

 

NOTE: this course is not available at the moment. We are revising it to include a part II on expansion joints.

Does materials incompatibility play a role on stress analysis?

January 28, 2013

Usually it would show a disparity between stresses at a particularpoint. For example, a carbon steel element joined to a stainless steel elementwould show significantly different stresses over the same temperature change.

Fluoroplastic Material

Does an anchor restrict motion in all direction that is X-Y-Z directions?

January 25, 2013

Anchors will restrict movement in all directions and will also restrictthe rotation of the pipe as well. In the stress analysis, we may see loads inall three directions which will tell us how “strong” the anchordevice has to be.

What is the importance of flexibility in a piping system?

March 15, 2009

Flexibility ensures that a piping system operates safely.
