Carbon steel eccentric reducer

The roundness of the eccentric reducer should not be greater than 1% of the corresponding end outside diameter, and the allowable deviation is ±3mm. The centerline of the concentric reducer should be coincident, and the allowable deviation of the eccentricity is ±5mm.
 
Eccentric reducer size tolerances shall comply with the provisions of Table 4.2.2-3.
 
Setting the temperature too high may cause the silicon carbon tube and reducer to rupture. The temperature must be reset. The heating element is double-threaded silicon carbon tube, coat corundum tube, the outside of the corundum tube is a new type of insulation material, the combustion tube adopts corundum reducer The tube is inserted directly into the silicon tube.
Carbon steel eccentric reducer
 
The quality of eccentric reducers shall comply with the provisions of the current national standard "Steel Butt-weld Seamless Fittings" GB/T 12459-2005 and shall meet the following requirements:
 
1) The appearance of the reducer should not be cracked, heavy skin, and wall thickness should be greater than the wall thickness of the large diameter end pipe section.
 
2) The roundness of the reducer should not be greater than 1% of the corresponding end outside diameter, and the allowable deviation is ±3mm. The centerline of both ends of the concentric reducer should coincide. The allowable deviation of the eccentricity is ±5mm.
 
3) The tolerance of the reducer size should meet the requirements of Table 4.2.2-3.
 
Eccentric reducer setting temperature is too high may cause the silicon carbon tube and reducer rupture, need to reset the temperature. The heating element is double threaded silicon carbon tube, jacket corundum protective tube, corundum protective tube exterior is a new type of insulation material, the combustion tube Use corundum reducer, directly into the silicon carbon tube inside.
