FAQ

Q1: What is the difference between ASME B16.9 and ASME B16.28?

A: ASME B16.9 covers dimensional requirements for all types of butt-welding fittings (elbows, tees, reducers, caps, etc.). ASME B16.28 is a supplementary standard specifically addressing short-radius (SR) elbows and 180° return bends. For long-radius elbows, ASME B16.9 is the primary reference standard.

Q2: What is the difference between long-radius (LR) and short-radius (SR) elbows?

A: Long-radius elbows have a bending radius equal to 1.5 times the nominal pipe diameter (R=1.5D); they offer low pressure drop and good flow characteristics, making them suitable for general piping systems. Short-radius elbows have a bending radius equal to the nominal pipe diameter (R=1.0D); they are more compact and suitable for installations where space is limited. The choice depends on installation space and flow characteristic requirements.

Q3: What is the chemical composition of ASTM A234 WPB material?

A: The typical chemical composition (maximum values) for ASTM A234 WPB is: C≤0.30%, Mn=0.29-1.06%, P≤0.050%, S≤0.058%, Si≥0.10%, Cr≤0.40%, Mo≤0.15%, Ni≤0.40%, Cu≤0.40%, V≤0.08%. The maximum Carbon Equivalent (C.E.) is 0.50.

Q4: How do I select the wall thickness for butt-welding elbows?

A: Wall thickness selection depends on the pressure rating and temperature requirements of the piping system. Common wall thickness options include STD (Standard), XS (Extra Strong), and SCH 20 through SCH 160. STD is suitable for general pressure applications, XS for higher pressures, and the SCH series increases in thickness according to pressure ratings. Please select the appropriate wall thickness based on the system’s design pressure.

Q5: What are the differences between surface finish options?

A: Black paint finish is suitable for general indoor service and provides basic rust protection. Hot-dip galvanizing is suitable for outdoor or corrosive environments, offering excellent corrosion protection. Light oil coating provides rust protection during transport and short-term storage; components must be cleaned prior to installation. Please select the appropriate surface treatment based on the installation environment.
