The rubber joint casting flange mainly alloying element and contains a small amount of other elements. Carbon containing less than 0.2% of carbon steel, carbon steel, carbon steel, carbon steel, carbon steel, carbon steel, 0.5% ~ 0.2%. With the increase of carbon content, the strength of carbon steel increases and the hardness increases. Cast carbon steel with high strength, plasticity and toughness, low cost, in the heavy machinery used in the manufacture of heavy load parts, such as rolling mill, hydraulic machine base, etc.;Used in the manufacture of large force and impact parts such as bolster, side frame, wheels
So on a railway vehicle coupler.Special carton steel to meet the special needs and refining of alloy cast steel,a variety of casting, usually containing a or a variety of high amount of alloy elements, in order to obtain certain special properties. For example, containing manganese 11% ~ 14% of the ability of high manganese steel impact wear,used for mining machinery,engineering machinery wear parts; with chrome or nickel chromium as main alloy element in all kinds of stainless steel for corrosion or 650 DEG C under the condition of high temperature parts, such as chemical valve,pump,container,or large capacity power plant turbine casing body.
However,single sphere rubber joint forging flange is generally lower than the casting flange with low carbon content is not easy to rust, forging flow linear,the organization is more compact,mechanical energy is better than casting flange.Single ball rubber joint forging flange ratio of the casting can withstand higher shear force and tensile force.The advantage of the casting is to be able to make a more complex form, the cost is relatively low;
So the use of different methods for different situations. Casting flange is more complex in the case of the shape, while the forging flange is not easy to rust mechanical performance is better than casting. Xin Li pipe factory is specialized in the pipeline industry for thirty years, our quality and service is worthy of your letter lazy.
HuanZhong Pipeline double flange limited telescopic joint can greatly reduce the vibration of pipeline transmission, the use life is long, the product quality conforms to the national standard.
