The application knowledge of concentric reducer

Eccentric reducer in the actual production add different elements of different functions and intensity, using certain production standard and the way to add, in which the use of a certain performance. Eccentric reducer characterized by carbon intensity is significantly higher than the same amount of carbon steel, has good toughness and plasticity, good weldability and corrosion resistance, etc. In order to improve and enhance the performance of the steel on the basis of the carbon steel to join other alloying elements, such as silicon, manganese, chromium, nickel, tungsten, vanadium, titanium, etc., this kind of steel is alloy steel.

Eccentric reducer according to difference of alloy elements, have different properties, such as high wear resistance, corrosion resistance, good low temperature resistance, good special features such as high magnetic. The center of the eccentric reducer as the main body section, straight pipe ends for eccentric, main body between a straight pipe section and eccentric reducing transition section, eccentric reducer the bottom line is straight line remains unchanged; Eccentric reducer of preparation methods are classified using multiple sets of mould, eccentric reducing in the metal tube directly, first set aside the main section in the middle of the metal one, again according to the request of tapered Angle, using multiple sets of hierarchical mold molding, step by step to suppress and into. Using this invention method processing eccentric reducer, the whole root eccentric size head without weld; Eccentric reducer as a dedicated pipe, used in corrosive strong liquid, can prolong the service life of the eccentric reducer, especially used for downhole eccentric water distributor’s shell, because there is no seam, not in the joint corrosion cracking; Flexible production technology, processing any straight pipe diameter, eccentric any longer eccentric reducer.

The size of the eccentric reducer pipe of different connections, is suitable for different industries are different. In electric power, mining, metallurgical and other industries, the material of the conveyor, output, are using at close range, high pressure conveying pipeline under considerable pressure, and sustained serious wear and tear, single material pipeline is very difficult to meet the requirements of this condition, especially the elbow, concentric reducer, such as stamping elbow pipe fittings, by considering its use of security, and service life, focus on improving pipe lined with toughness, impact resistance, and abrasion resistance. At the same time also want to consider the integrated intensity of the pipe and elbow problems.

Eccentric reducer before bonding, use dry cloth to bell mouth and socket lateral wipe the handle, when the surface with oil pollution must be with acetone to wipe clean, have the following points to note:

1, control diameter: DIN, 3 a/IDF standards, ISO standards;
2, the international industry standard: DIN, ISO, SMS, 3 a, IDF, etc;
3, the product material: 304, 316, 316 l stainless steel;
