FAQ

Q1: How to choose between LR and SR elbows?

LR elbow (R=1.5D) offers larger radius, lower flow resistance and less wear – preferred for high-pressure, high-temperature, high-velocity and solids-bearing media. SR elbow (R=1D) has smaller radius, saves space – suitable for space-limited or low-pressure non-critical applications, but higher flow resistance.

Q2: How to select between 304/316L, duplex steel and nickel alloy?

304 suits general water, gas and mild corrosive environments. 316L with molybdenum offers better pitting resistance than 304 for chemical and marine applications. Duplex (2205/2507) provides high strength and excellent stress corrosion resistance for high-temperature chloride-rich conditions. Nickel alloy (C-276/Inconel) resists extreme acids and high-temperature oxidation for severely corrosive high-temperature environments.

Q3: What are the applications for polished vs. pickled/passivated surfaces?

Pickling/passivation removes welding HAZ oxide scale and restores corrosion resistance – suitable for most chemical and petrochemical applications. Polishing achieves Ra≤0.4μm surface finish, reduces media adhesion and bacterial growth – suitable for sanitary clean piping in pharmaceutical, food and bioengineering applications.

Q4: How to select wall thickness for butt-weld elbows?

Wall thickness is calculated per ASME B31.3 or GB/T 20801 based on design pressure, temperature and corrosion allowance. Standard chemical piping uses SCH10S/SCH40S; high-pressure uses SCH80S and above; corrosive media require additional corrosion allowance in selection.
