Material Selection

Superior Design and Results through Material Science

PT&P has a unique perspective on the opportunity for its customers to customize to better meet business and operating objectives.  As the only major Global Player to manufacture Pipe Supports, Expansion Joints, and run an ASME stamped facility, PT&P has superior manufacturing skills to accommodate a wide variety of materials, such as Nickel-based Super Alloys, that are beyond the capability of other Pipe Support manufacturers.  In addition, PT&P is one of the very few Pipe Support manufacturers to have started as a Pipe Stress Engineering company.  As a result, we can also easily utilize FEA and Stress Analysis to fully design new solutions to optimize against design requires and even load test the solution in our production facility.  The table below gives a summary of just some of the materials that PT&P works with and cost/capability of these materials.

An example of advances in steel in which PT&P customers are not leveraging advances in high strength steel engineering and production.  Historically, high strength steel used manufacturing techniques such as quenching and tempering which led to higher yield strength at the cost of ductility and weldability.  This caused costs to manufacture with materials such as A514 to be far higher than A36.  Steel suppliers have responded by implementing more advanced manufacturing techniques and maintain much tighter control of molecular structures in order to achieve higher yield strength without a major loss of ductility and workability.  One of the major drivers of this has been the AHSS (Automotive High Strength Steel) 3.0 initiative.  For structural steel, this can be seen in products such as Domex 100XF which offer yield strength as much as 3 times greater than A36 while still maintaining good workability and weldability.

The following are examples of design objectives that can be improved via material optimization:
