Eccentric Reducers

SDR11

Short spigot or buttweld eccentric reducers, SDR11 are an extremally useful way of gaining height or fall within the original pipe diameter. Reducing on a level plain be it on the top or bottom of the pipe. In horizontal intakes or pump suction piping, it is best to install the reduction level with the top, this prevents airlocks building up in the pipeline and getting trapped in the pump’s impeller. Air trapped in a pipe or pump is very detrimental and can end up totally blocking the pump, making it cavitate and overheat. It is generally considered best practise to use concentric reducers on the vertical delivery side of the pump. In pipe galleries, or pipe racks, eccentric reducers are used to keep the pipe on the same level, whatever the size. It is far easier to bracket the pipes directly to the pipe rack or cable tray without having to use spacers to make up the gap. Advanced Piping also has a full range of pipe clips and brackets for this. Eccentric reducers can be used both as an SDR11 or 17 expander or reducer, and with our enormous (almost endless) size combinations Advanced Piping can machine an eccentric to your exact size and pressure rating required from 63mm to 1600mm in PN6.3 SDR26, to PN25 SDR7.4.
