ASME B31.3: PROCESS PIPING

After planning for the vacation to the Ancol, and make preparation for everything, I think that would be enough for today, because I have to continue my job and input few data which is about welding consumable, etc. While I use the computer, so I stole few minutes to update this Piping & Fabrication blog and now we comes to ASME B31.3: PROCESS PIPING.

Scope
This code prescribes requirements for the materials, design, fabrication, assembly, erection, examination, inspection, and testing of piping within the property limits of facilities engaged in the processing or handling of chemical petroleum or related products. Figure A4.4 provides an illustration of the scope of ASME B31.3. The requirements of ASME B31.3 apply to piping for all fluids, including raw, intermediate, and finished chemicals; petroleum products, gas, steam, air, and water; fluidized solids; and refrigerants.

In case of packaged equipment, the interconnecting piping with the exception of refrigeration piping shall be in compliance with the requirements of ASME B31.3. The refrigeration piping may conform to either ASMEB31.3 orASMEB31.5.

The requirements of ASME B31.3 do not apply to piping systems designed for internal gauge pressures at or above 0 but less than 15 (100 kPa gauge) psig provided the fluid handled is nonflammable, nontoxic, and not damaging to human tissue and its design temperature is from -29°C (-20°F) through 180°C (366°F).

The following piping and equipment are not required to comply with the requirements of ASME B31.3:
•    Power boiler and the boiler external piping
•    Piping covered by ASME B31.4, B31.8, or B31.11, although located on the company property
•    Piping covered by applicable governmental regulations
•    Piping for fire-protection systems
•    Plumbing, sanitary sewers, and storm sewers
•    Tubes, tube headers, crossovers, and manifolds of fired heaters which are internal to the heater enclosures
•    Pressure vessels, heat exchangers, pumps, compressors, and other fluid-handling or processing equipment, including internal piping and connections for external piping

Effective Edition, Addenda, and Code Cases
The effective edition, addenda, and code cases shall be determined similarly to the approach delineated for ASME B31.1 for piping systems other than the nuclear safety-related piping systems.
