Industrial Piping Materials
Industrial Piping Materials
- Industrial piping systems are crucial in various sectors, including oil and gas, chemical processing, power plants, water treatment, and manufacturing.
- Selecting the right piping material is essential to ensure durability, efficiency, safety, and cost-effectiveness.
- In this article we explore the different types of industrial piping materials, their properties, and their applications.
Codes Used
- The two principal international codes used for the design and construction of a process plant are
- ASME B31.3, Process Piping, and the ASME Boiler
- Pressure Vessel Code Sections
- Generally, only materials recognized by the American Society of Mechanical Engineers (ASME) can be used as the materials of construction (MoC) for piping systems within process plants
- They meet the requirements set out by a recognized materials testing body, like the American Society of Testing and Materials (ASTM).
- There are exceptions, however; the client or end-user must be satisfied that the non-ASTM materials offered are equal or superior to the ASTM material specified for the project.
- The Unified Numbering System (UNS) for identifying various alloys is also quoted.
- This is not a specification, but in most cases, it can be cross-referenced to a specific ASTM specification.
