What does ASME B 31.3 specify?

Question

Thanks in advance for your help!

Answer 1

ASME B 31,3 is for CHEMICAL PIPES OF PROCESS OF REFINERIES AND PLANTS.
B3 1.3 Process Piping: piping typically found in petroleum
refineries, chemical, pharmaceutical, textile, paper,
semiconductor, and cryogenic plants, and related processing
plants and terminals.
(a) This Code prescribes requirements for materials
and components, design, fabrication, assembly, erection,
examination, inspection, and testing of piping.
(b) This Code applies to piping for all fluids, including:
(1) raw, intermediate, and finished chemicals;
(2) petroleum products;
(3) gas, steam, air, and water;
(4) fluidized solids;
(5) refrigerants; and
(6) cryogenic fluids.
Also included
within the scope of this Code is piping which interconnects
pieces or stages within a packaged equipment
assembly.
It ALSO includes:
Stress Tables for Metallic Piping and Bolting Materials
Stress Tables and Allowable Pressure Tables for Nonmetals
Physical Properties of Piping Materials
Flexibility and Stress Intensification Factors

The standards includes all the dimensional standards that suits a particular piping.

In closing, the ASME B 31.3 is the only accepted code that exists for process piping systems. It is directly required by law in Canada and indirectly in the U.S. by means of OSHA process safety requirements and insurance mandates. However, the fact that the code is required should not be the only reason to compel users to follow it. If followed, it is an excellent means to insure the safe, reliable installation of process piping, as evidenced by the excellent record that exists in chemical plants and petroleum refineries throughout North America.
