Eccentric reducers are characterized by higher strength than carbon steel with the same carbon content, better toughness and plasticity, good weldability and corrosion resistance. What are the special functions of eccentric carbon steel pipe reducers.
Eccentric reducer in the actual production, adding different elements for different functions and strength, using certain production standards and methods to add, in which the use of a certain performance, In order to improve the properties of steel, other alloying elements such as silicon, manganese, chromium, nickel, tungsten, vanadium and titanium are added to carbon steel. This kind of steel is called alloy steel.
When absorbing water, the water pressure of the suction pipe section is reduced, and the gas dissolved in the water will separate out. If concentric reducer is used, these gases can not be discharged in time, and will accumulate and block at the protrusion, forming air resistance. The water pump will also have noise, and the water delivery capacity will be greatly reduced. If eccentric reducer is used, the separated gas will be discharged in time, and will not form air resistance.
When the pipe diameter itself is not big, and the difference between the front and back pipe diameters is not big, the phenomenon of air resistance may not be so obvious when using concentric reducer, and the air pressure change of self suction type in the process of water absorption is not so big, so the harm is not reflected
