JIS B2312 SUS304 Buttweld Pipe Fitting Stainless Steel Concentric Reducer
TONG CHUANG GROUP is engaged in buttweld pipe fitting manufacturing， including elbow， tee， caps， reducer， stub end. We supply various material grades: stainless steel / duplex steel / nickel alloy. These find application for industry fields use，such as petroleum， power， papermaking， chemical， aviation， boiler heat， exchanger fields ; electric， shipbuilding， construction fileds; foodstuff，medical equipment， and other fields.
The function of both types of reducer is to reduce the line from a larger to a smaller pipe size， this obviously results in an increased flow pressure.
The concentric reducer is manufactured so that both inlet and outlet ends are on a common centre line. The concentric reducer is easier and less expensive to produce but does not allow quite the same versatility as the eccentric reducer. The lengths of both types are fixed by manufacturing standards.
