API 5L Specifications covers seamless and welded pipe suitable for use in conveying gas, water, oil, and other liquefied media.
Dimensions of the pipes are covered in following Standard
ASME B36.10 – Welded and Seamless Wrought Steel Pipe (Carbon & Alloy Steel)
Pipe Size up to 2” are considered small bore pipe. However, some company considered up to 2.5″ pipe as a small bore.
Pipe Size above 2″ are considered large bore or big bore pipe
