Hotline Steel Trading supplies MS (mild steel) concentric reducers from Dubai to contractors, fabricators and maintenance teams across the UAE. A concentric reducer joins two pipes of different diameters on a shared centre line, so the pipe run stays straight and flow changes size evenly.
They are the usual choice for vertical lines and for gas and liquid lines where trapped air is not a concern. Supplied in carbon steel to ASTM A234 WPB, dimensioned to ASME B16.9, from ½″ to 24″.

A concentric reducer keeps both pipe ends on the same centre line. An eccentric reducer offsets one side so the top or bottom of the pipe stays level, which stops air or liquid collecting, so it is normally used on pump suction lines and horizontal runs.
MS stands for mild steel, a low carbon steel. Our MS concentric reducers are made to ASTM A234 WPB.
