Eccentric head

Eccentric Reducer (eccentric head) roundness should not exceed 1% of the respective ends of the outer diameter, and the tolerance of ± 3mm; concentric reducer centerline ends should overlap, their tolerance for eccentricity value ± 5mm. Quality eccentric reducer should be consistent with the provisions of GB / T 12459-2005 The current national standard "welded steel seamless pipe fittings" and should meet the following requirements: 1) the appearance of eccentric reducer should not have cracks, heavy leather, wall thickness should be greater than the thickness of the large diameter end of the tube segment. 2) roundness eccentric reducer should not exceed 1% of the respective ends of the outer diameter, and the tolerance of ± 3mm; concentric reducer centerline ends should overlap, their tolerance for eccentricity value ± 5mm. 3) eccentric reducer size tolerances shall comply with the provisions of Table 4.2.2-3. Eccentric Reducer (eccentric head) material is a low carbon structural steel, low alloy content, generally less than 3%. Eccentric Reducer (eccentric head) in the actual production of which add different elements in different functions and strength, the use of certain production standards and methods to add, has certain properties in which the use of eccentric reducers tube which is characterized by intensity was significantly higher than the same amount of carbon in the carbon steel, has good toughness and ductility and good weldability and corrosion resistance, etc. In order to improve and enhance the performance of the steel, carbon steel on the basis of adding Other alloying elements, such as silicon, manganese, chromium, nickel ,, tungsten, vanadium, titanium and the like, which is called the steel alloy. Eccentric Reducer (eccentric head) according to different alloying elements, have different properties, such as high wear resistance, corrosion resistance, low temperature, high magnetic properties, good special. Alloy steel use is divided into structural steel, alloy tool steel and special properties of the steel. Eccentric reducer safe, health and environmental protection, affordable, thin-walled pipes and new, reliable, simple and convenient method for the development of a successful connection, it has more advantages to other pipe irreplaceable, Engineering will increasingly more use will become increasingly popular, prospect. Eccentric Reducer (eccentric head) of reduced diameter forming process is the big end diameter pipe with a diameter equal to the tube into the forming die by the tube along the axial direction of repression, the movement of the metal along the cavity and Shrinkage forming. Eccentric Reducer (eccentric head) scale: GB American Standard British standard and non-standard high-pressure press, in addition to the use of steel as a raw material produced outside diameter pipe, the department specifications diameter pipe can be adopted with steel stamping processes production.
