Description
Material Specifications:
STD Wall A/SA234 B16-9 WPB Seamless Carbon Steel Weld Fitting
This is a standard wall thickness concentric reducer made of ASTM/ASME A234 WPB carbon steel, designed for butt welding, and manufactured to ASME B16.9 specifications. It?s used in piping systems to connect nominal pipe, maintaining a centered flow path, typically in applications like oil, gas, or industrial fluid transport where moderate to high temperatures and pressures are involved.
- *STD* designates Standard Weight (standard wall). This size and thickness do not correspond to any pipe schedule number.
- Dimensions conform to ASME B16.9 & material conforms to ASTM SA-234 Grade B.
- Seamless Butt Weld Fittings conform to ASTM A/SA234 WPB through 24"
- Weld Fitting Dimensions conform to ANSI B16.9, B16.11, B16.28 through 24"
- Weld Fitting Dimensions larger than 24" conform to MSS-SP-48
- Weld Fitting Dimensions conform to ASME B16.9, B16.25
- Carbon content not to exceed .25% maximum.
- Manufacturing Facilities are ISO Certified
End Connection:
Butt Weld End x Butt Weld End
NPS - Nominal Pipe Size
These are nominal pipe sizes (NPS), which refer to the approximate inner diameter of standard pipes.

Wall Thickness:
STD Wall
*STD* designates Standard Weight (standard wall). "Standard," referring to the wall thickness or schedule of the pipe fitting. "STD" corresponds to a specific wall thickness defined by ASME standards (e.g., Schedule 40 for many sizes), ensuring compatibility with standard piping.

Shape:
CONC REDUCER: Short for "Concentric Reducer." This describes the shape of the fitting. A concentric reducer has a symmetrical taper, meaning the centerline of the larger and smaller ends align, keeping the pipe?s flow centered. (Contrast this with an eccentric reducer, where the centerline is offset.)
Material Construction:
Seamless
Standards Met:
ASTM A/SA234 WPB / ASME B16.9 / ASTM SA-234 Grade B
A/SA234: This is the material specification from ASTM (A234) and ASME (SA234) standards, which cover wrought carbon steel and alloy steel pipe fittings for moderate and high-temperature service. WPB: The grade of the material. "WPB" stands for "Wrought Pipe B-grade" and indicates a carbon steel fitting with specific mechanical properties (e.g., tensile strength) and chemical composition (e.g., carbon, manganese). It’s commonly used in pressure piping systems and is weldable.
