A "Standard" will cover a specific item or part of a specific item.
- B16.10 Face-to-Face and End-to-End Dimensions for Ferrous Valves
- B16.28 Wrought Steel Butt welded Short Radius Elbows and Returns

A "Code" will cover the technical issues of the Design of all Piping for a type of Facility.
- B31.3 Chemical Plant and Petroleum Refinery Piping
- B31.4 Liquid Pipeline Transportation Systems for Hydrocarbons, Liquid Petroleum Gas, Anhydrous Ammonia, and Alcohol's
Do it once and Do it Right

Seek and you shall find ... From the "Standards" tab (above)

Piping Codes

Piping codes defines the requirements of design, fabrication, use of materials, tests and inspection of pipes and piping systems.
A code has a limited jurisdiction defined by the code.

Piping Standards

Piping standards define application design and construction rules and requirements for piping components as flanges, elbows, tees, valves etc.
A standard has a limited scope defined by the standard.
