What are the differences between ASME B31 1 and ASME B31 3?

What are the differences between ASME B31 1 and ASME B31 3?

ASME B31. 1 covers the requirements of boiler external piping, and ASME B31. 3 does not. 1 fittings can be used as part of a boiler external piping design, ASME B31.

What is B31 1 Power piping?

ASME B31. 1, Power Piping Code, prescribes requirements for the design, material, fabrication, erection, test, and inspection of power and auxiliary service piping systems for electric generation stations, industrial and institutional plants, central and district heating plants, and district heating systems.

What is the purpose of ASME B31 1?

1 or Power Piping Code provides rules for piping typically found in electric power generating stations, in industrial and institutional plants, geothermal heating systems, and central and district heating and cooling systems.

What is Category M piping?

“a fluid service in which the potential for personnel exposure is judged to be significant and in which a single exposure of a very small quantity of a toxic fluid, caused by leakage, can produce serious irreversible harm to persons on breathing or bodily contact, even when prompt restorative measures are taken.”

What is B31 3 piping?

ASME B31. 3 contains requirements for piping typically found in petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals. cryogenic fluids.

What is the difference between process piping and power piping?

Process piping means piping systems and their component parts, that are not building services or power piping systems, and that may be installed in petroleum refineries, chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants, and related processing plants and terminals.

What is the latest edition of ASME B31 1?

ASME B31. 1-2020 revises the 2018 edition of the same standard code for power piping, and, as the key document for the industry, it contains numerous changes crucial for keeping the standard current.

What is the difference ASME B31 Code for Pressure piping?

ASME B31 was earlier known as ANSI B31. The B31 Code for Pressure Piping, covers Power Piping, Fuel Gas Piping, Process Piping, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids, Refrigeration Piping and Heat Transfer Components and Building Services Piping.

What is piping spool fabrication?

Pipe spool fabrication is fabrication (cutting, bevelling, welding) of metal pipes and elbows in order to pipe lines or pipe structures. most spools are manufactured in pipe spool fabrication shops where they have machinery for cutting, sawing, bevelling and welding.

Is Steam a Category D fluid?

Category D Fluid Service is a less hazardous service. For example, 150# steam can be classified as Category D Fluid Service even though an individual in a container filled with 150# steam would obviously suffer tissue damage.

What is category K fluid?

Category “K” fluid service: Fluid service for which the owner specifies the temperature and pressure rating more than 2500# or it specifies to use of chapter ix for piping design.

What’s the difference between B31 and B31.3 piping?

B31.3 has the greatest width of scope of any B31 Pressure Piping Code. That is why B31.3 created several “fluid services”, each with specific rules. B31.1 on the other is about 40 years. B31.3 plants generally have a plant life of of about 20 to 30 years.

When was the ASME B31.3 Code Last updated?

This Guide provides information for the proper application of the ASME B31.3 Code “Process Piping,” It was last updated for the 2002 edition. ASME B31.3 applies to process piping and tubing systems at Los Alamos National Laboratory (LANL). This Guide also contains ASME B31.1 and AWWA compliant Piping Specifications.

Can a ASME B31.3 fitting be used in a boiler?

So, whereas some ASME B31.1 fittings can be used as part of a boiler external piping design, ASME B31.3 fittings cannot be. For example, if some boiler external piping systems needs a valve replacement, the replacement valve must be registerable to ASME B31.1, and the material must be suitable for boiler external piping.

How is the SIF used in B31.1?

If its considered then validity of using the SIF from B31.3. B31.1 uses a simplified one SIF approach (the maximum) for in and out plane .In the B31.1 Code, the SIF used is the LARGER of the two (inplane as compared to out-of-plane)and this larger SIF is applied to both of the bending moments occuring about mutually perpendiculat axes.
