Stainless steel reducers are tools for connecting pipes of different sizes. Stainless steel reducers can be divided into eccentric stainless steel reducers and concentric stainless steel reducers according to the centerline. When setting stainless steel reducers, the two ports The projection is a concentric circle, which is a concentric stainless steel reducer. The reason why the eccentric stainless steel reducer is called eccentric is that the two centers do not coincide, but are on a straight line. These two different stainless steel reducers are also suitable for different ranges.
Concentric stainless steel reducers are used on vertical pipes, and eccentric stainless steel reducers are used on horizontal pipes. When using, it needs to be marked with a flat bottom or top flat. When the flow rate of the liquid in the pipeline changes, the flow rate requirement when using stainless steel reducers is not too large. Especially in the installation of the pump inlet reducer, in order to prevent the gas from accumulating at the reducer and avoid the cavitation caused by errors during the installation process, the horizontal inlet pipe of the pump uses an eccentric stainless steel reducer to prevent cavitation. Therefore, when the horizontal inlet pipe of the pump is reduced, an eccentric stainless steel reducer is used in order to cooperate well with the joints of the control valve, flow meter, and other instruments. When the pipeline enters the pump horizontally from top to bottom, the stainless steel reducer should be flat.
Stainless Steel Reducer
The application of stainless steel reducers is very extensive, and many industries are inseparable from it. Natural gas, hydropower, construction, petroleum, boilers, etc., the forming process of the surfacing elbow used in the pipeline system is very complicated, and needs to be based on different materials and uses Welding, casting molding under a certain pressure.
Stainless steel reducer material can be divided into stainless steel reducer and alloy steel reducer, and the steel used for stainless steel reducer is No. 20 steel or Q234, Q345, and other steels.
In the stainless steel reducer, the eccentric stainless steel reducer is mainly used as a kind of connecting pipe fitting at the reducer of the pipeline. The eccentric stainless steel reducer is generally shrink-molded, or it can be compressed by the expansion-expansion process. The stamping method can also be used for some special specifications of stainless steel reducer. The eccentric stainless steel reducer can not only produce stainless steel pipes with different diameters using steel pipes as raw materials but also use a steel plate forming method to press some special stainless steel pipes with different diameters. According to the inner surface size of the stainless steel reducer, design the shape of the die, punch the steel plate with the die, and stretch it.
Stainless steel reducing agent can also be divided into electric furnace steel, converter steel, and flat furnace steel according to the smelting method, and can be divided into special killed steel, boiling steel, semi-killed steel and killed steel according to the deoxidation method. Carbon steel can be divided into high carbon steel, medium carbon steel, and low carbon steel according to carbon content. According to the content of sulfur and phosphorus, carbon steel can be divided into ordinary carbon steel, special steel, high-quality steel, etc. In general, the higher the carbon content of stainless steel pipes, the greater the hardness and strength, but in contrast, plastic Will become very low. So what is the reason? The mechanical properties mainly depend on the carbon content in the steel. In general, steels that do not contain large amounts of alloying elements are sometimes called carbon steels and ordinary steels.
