WebCalculate ASME B31.3 process piping required branch reinforcement for welded and extruded branches. The calculations are valid for right angle welded branches, angled welded branches ≥ 45 degrees, and right anngle extruded branches. Extruded branches must be used for high pressure piping. WebNPT is the best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal. NPT has a tapered male and female thread which seals with Teflon® tape or jointing compound. ASME B1.20.1 covers dimensions and gaging of NPT pipe threads for general purpose applications. WebWhen the branch duct reaches the end, I draw a curve line connecting the diffuser to the duct, indicating a flexible duct connection. Remember I mentioned earlier, all the diffuser neck size is 150mm (6″) and thus, all the flexible duct size is also 150mm (6″). Hence, I don’t really indicate the size in the layout drawing. seethewater terminus
