How is sponge iron made into a highly active filler?
Sponge iron deoxidizer is a high-activity filler after activation treatment, running at normal temperature, no heating, low operating cost, overcoming the thermal deaeration, vacuum deaerator heating energy consumption is the sponge-like porous iron particles, The soft floc which does not dissolve in water, when it accumulates to a certain extent, can be drained by backwashing.
Restore the sponge iron to its initial oxygen scavenging capacity. Providing conditions for the reaction of dissolved iron in the water with active iron. When the water containing oxygen passes through the sponge iron, a de-ironing device may be added for the steam boiler or the dehydration of the feed water having strict requirements for the feed water Fe2+. In the iron-ion water of the low-pressure steam boiler to remove water, the oxygen and iron undergo a complete oxidation reaction, which provides a condition for the dissolved oxygen in the water to react with the active iron when the oxygen-containing water passes through the sponge iron. The oxygen in the water and the sponge iron undergo a complete oxidation reaction. After the activated treatment, the sponge iron deoxidizer removes oxygen into a soft floc which is insoluble in water. When it accumulates to a certain extent, it can be backwashed. Discharged, the sponge iron is restored to the initial oxygen scavenging capacity of the sponge-like porous iron particles, providing an opportunity for the dissolved oxygen in the water to react with the active iron to eliminate the dissolved oxygen content of the effluent.

Single End Manual Beveling Machine :
The single end Manual Beveling Machine is one of manual and simple machine to chamfer the front end of the pipe or pipe fittings to form the angle 37.5 degree on the fitting ends. It has one beveling head and beveling the sides on by one. It is use for the smaller size pipe or Pipe Fitting for easy welding. application material :carbon steel , stainless steel ,alloy steel . But different material need to change different cutting tools . Beveling size range:21 mm - 3000mm . For the fixture lock function : manual type and hydraulic type .
