241 Bushing Malleable Iron Pipe Fittings Pipe Fitting Reducer
- 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 .
- We will test the material quality of the cast steel sample by using
Oxford Instruments’s Spectrometer .
- High heat value natural gas annealing oven will be applied to
control the annealing operation and raise the material’s physical performance.
- 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.
