Eccentric size heads apply small knowledge

TIME：2019-05-25

Eccentric reducer in the actual production add different elements of different functions and intensity, using certain production standard and the way to add, in the use of them has a certain performance. The eccentric size head is characterized by carbon steel with significantly higher strength than the same carbon, with good toughness and plasticity, good weldability and corrosion resistance. In order to improve and improve the performance of steel, add other alloy elements on the basis of carbon steel, such as silicon, manganese, chromium, nickel, tungsten, vanadium, titanium, etc. This kind of steel is called alloy steel.

The eccentric sized head has different properties according to the addition of alloy elements, such as high wear resistance, corrosion resistance, low temperature resistance, high magnetic properties and other good properties. The center of eccentricity size head is the main pipe section, and the two ends are eccentricity, and the main part of the main pipe is in the transition section with the eccentricity. The bottom line of the eccentricity is the straight line. 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. The eccentric sized head with the method of the invention is used, and the whole eccentric size has no welds. 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; The production process is flexible, can process any diameter, eccentric straight pipe section any long eccentric size head.

The size of the eccentric size of the head is different, and the 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. The overall strength of pipe and elbow is also considered.

Before the eccentricity head is adhered to, the dry cloth will be applied to the side of the socket and the outside of the socket. When the surface is covered with oil, it should be wiped clean with acetone, and the following points should be noted:

1. Control caliber: DIN standard, 3A/IDF standard, ISO standard;

2. International industrial standards: DIN, ISO, SMS, 3A, IDF, etc.

3. Product materials: stainless steel 304, 316, 316L;
