Description
Material Specifications:
STD Wall A/SA234 B16-9 WPB Seamless Carbon Steel Weld Fitting
Eccentric reducer made of ASTM A234 WPB carbon steel with a standard wall thickness, designed for butt-welding into a piping system. It conforms to ASME B16.9 standards and is typically used in industries like oil and gas, chemical processing, or power generation to transition between pipe sizes while maintaining flow characteristics and structural integrity. The eccentric design makes it ideal for specific applications where alignment or drainage is a concern.
- *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

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:
Eccentric Reducer
Unlike a concentric reducer, which reduces the pipe diameter symmetrically along the centerline, an eccentric reducer has one side offset. This means the flat side of the reducer aligns with the bottom or top of the pipe (depending on installation), which is useful in applications where air or liquid accumulation needs to be avoided (ex: maintaining a level bottom for drainage or preventing gas traps).

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.
