What is the most typical welding joint used for welded pipe in smaller diameters?

[timsch]

Referring to ASME B31.3 Table 302.3.4, there are several different joints listed. What would be the most typical joint used if welded stainless pipe was ordered in the USA? Sizes are usually in the 1/2 - 3" range; schedules 10-160 range.

Thanks.
