PT&P has spent extensive time better understanding the needs of Plant Engineers and Maintenance staff. We conduct 30-50 in-person lunch and learns each year at various plant locations globally. PT&P used this learning to translate the common problems faced by Plant Engineering and Maintenance Personnel into the products, services, and tools to solve these problems. PT&P has the broadest and most highly engineered set of Pipe Stress solutions globally. We believe this makes us uniquely positioned to help our Plant customers with issues related to Piping and Pipe Stress.
The following are the key solution areas that PT&P has received consistent interest from Plant Engineers and Maintenance Personnel:
Internal pipe flow (pulsation, two-phase and turbulence) or external pipe flow (wind) can cause vibration in the piping system, which can in-turn have the potential to cause damage. PT&P has extensive experience in resolving vibration issues (stiffening, energy dampening, and isolation).
Water Hammer (or Steam Hammer) Solutions
A pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly is caused water hammer. A water hammer commonly occurs when a valve closes suddenly at the end of a piping system.
Contact Corrosion (or Cathodic Corrosion) Solutions
An issue when two different metals come in contact with water is called contact corrosion. The base metal is transformed into an anode, which leads to accelerated corrosion of the first metal, and then the second metal that it is in contact with.
Piping Alignment Solutions
As the diameter of piping increases, construction teams have an increased difficulty in getting complete alignment which can pose issues for highly sensitive equipment such as compressors.
Engineered Pipe Support and Expansion Joint Audit Solutions
During an audit, the main goal is to return the piping system to the original design parameters per the pipe stress model. PT&P is the only major global manufacturer of expansion joints and engineered pipe supports. We have a database of over 1000 audits performed in 41 countries, as well as over 3 million pipe supports and expansion joints currently in-service.
Pipe Stress Analysis
Predictions of stresses in the piping and loads on equipment resulting from thermal gradients, thermal transients, weights, pressure, and bolt-up strain is called pipe stress analysis or thermal flexibility analysis.
