Concrete pump reducer pipe is made of Q235 steel, which have high strenth. In the concrete pump truck working, various concrete pump pipes and elbows are required. Reducer is also an essential concrete pump spare parts. Q235B has low carbon and is easy to weld. If higher wear resistance is required, Hardox400 wear plate can be welded.
