ASTM A234 WPB Reducer

ASTM A234 WPB Eccentric And Concentric Pipe Reducer Manufacturer In China.

ASTM A234 is the standard of pipe fitting materials that demonstrate different carbon steel and alloy steel properties. WPB is a steel grade where W represents weldable, B is the grading B, and P represents pressure. We are one of the top WPB Reducer Manufacturer In China, as we produce the best quality reducers of the given standard. The ASTM A234 WPB Reducer is used for reducing the size of the pipe from a large to a small-bore. The Carbon Steel A234 WPB Pipe Reducer is buttwelding closes usually used for welding with steel pipes of A106, A53, GR. B, or API 5L GR. B material. We are one of the top exporters of SCH 40 WPB Reducer in China, used in pressure piping of moderate and high-temperature services.

Our ASTM A234 WPB Concentric Reducer is used for joining sections of pipes and tubes on the same axis. Con Reducer ASTM A234 is cone-shaped and mainly used in cases where there is a shift in the diameter of the pipe. We also have a massive stock of SA234 Eccentric Reducer, which is used between two pipes of different diameters. Our ASTM A234 WPB Eccentric Reducer is mainly used if the pipe’s diameter on the fitting’s upstream side is larger than that of the downstream side.

Formula Of Carbon Steel A234 Seamless Reducer

ASTM A234 WPB Reducer weight formula is 0.02466 * S <(D+d)/2 – S> * H / 1000

d = Small end dia. in milli.
D = Large end dia. in milli.
S = Large end Thick. in milli.
H = Height from end to end.
