241 Bushing Malleable Iron Pipe Fittings Pipe Fitting Reducer Bushing

  1. The DISA from Denmark,DJ AMF form Japan and the automatic production line from Sinto is introduced in malleable iron bushing product-line to ensure product quality .
  2. We will test the material quality of the cast steel sample by using Oxford Instruments’s Spectrometer .
  3. High heat value natural gas annealing oven will be applied to control the annealing operation and raise the material’s physical performance.
  4. Because of the air-tight test,we guarantee each pipe fitting bushing with no leakage .


Cast iron contains carbon, in the form of graphite, in its molecular structure. It is composed of a crystalline structure as are all metals; i.e. it is a heterogeneous mass of crystals of its major elements (Iron, Manganese, Carbon, Sulphur and Silicon). One condition which can occur in the presence of acid rain and/or sea water is "graphitization." The stable graphite crystals remain in place, but the less stable iron becomes converted to insoluble iron oxide (rust). The result is that the cast iron piece retains its shape and appearance but becomes weaker mechanically because of the loss of iron. Graphitization is not, however, a common problem. It generally will occur only after bare metal is left exposed for extended periods, or where failed joints allow the penetration of acidic rainwater to interior surfaces.

This corrosion process is galvanic, with the carbon present acting as the most noble (least corrosive) element and the iron acting as the least noble (most corrosive) element. The composition or microstructure of the iron affects the durability of the object because the rate of corrosion is dependent upon the amount and structure of the graphite present in the iron.
