The role of eccentric reducers

When the two sizes of different pipes are connected together, what method do you have? Do you know the reducing pipe this thing, it can put two sizes of different pipes perfectly together, is not very amazing? Now you are not very anxious to let Xiaobian to introduce it to you? Today, Xiaobian will introduce eccentric reducing pipe to you. Now is it more confused, what is eccentric? Hurry up and quickly follow Xiaobian together to understand it, more important is its role!

 

Reducers, also called size heads, are used to connect pipes of different sizes; Generally, it is divided into concentric reducers and eccentric reducers. When the projection of the two ports of the reducers is concentric circles, it is called concentric reducers, and the projection of the eccentric reducers is a small circle cut to the outer circle
Eccentric -diameter pipe (eccentric -diameter pipe) is a kind of pipe fittings used for pipe reducing, usually the forming process for reducing pressing, expanding pressing or reducing and expanding pressing, for some specifications of reducing pipe can also use stamping forming. In addition to the production of eccentric reducing pipe using steel pipe as raw material, some specifications of reducing pipe can also be produced by steel plate stamping process. The shape of the die used for drawing is designed according to the size of the reduced inner surface, and the steel plate after blanking is pressed and drawn by the die.
The eccentric reducer is expressed as the diameter of the large head multiplied by the diameter of the small head multiplied by the thickness.
Standard for eccentric reducing pipe:
National standard American standard British standard and all kinds of non-standard high pressure stamping.

 

The reducing process of eccentric reducing tube is to put the tube blank with the same diameter as the big end of the reducing tube into the forming die. By pressing the tube blank along the axial direction, the metal moves along the die cavity and shrinks into shape. According to the size of the reducing tube, it can be divided into one pressing forming or multiple pressing forming.
Eccentric reducer is characterized by carbon steel with strength significantly higher than the same amount of carbon, good toughness and plasticity, and good weldability and corrosion resistance.

 

Quality specification for eccentric reducers
Electric force specification for eccentric reducers GD0506-0507 Corresponding specifications for flanges and tubes supporting pressure vessels: JB/T4700~4707-2000 to fulfill the national code (GB/T9112-2000), Code of the Ministry of Machinery (JB/T81-1959, JB/T74-1994), code of the Ministry of Petrochemical (SH3406-1996), code of the Ministry of Chemical Industry (HG/T5010-1958, HG/T20592-2009) and so on. The raw material of exported forged steel flange conforms to ASTM A105 specification of the United States. The quality of eccentric reducers should conform to the current national standards, and the size tolerance error of eccentric reducers should conform to the provisions in Table 4.2.2-3. The roundness of the eccentric reducing pipe should not be greater than 1% of the outer diameter of the corresponding end, the appearance of the eccentric reducing pipe should not have cracks, heavy skin, wall thickness should be greater than the wall thickness of the large diameter end pipe segment, and the allowable error is ±3mm; The center lines of the two concentric reducers should coincide, and the eccentricity should be allowed to be ±5mm.
Product use:
Petroleum gas pipeline engineering, natural gas pipeline engineering, chemical plant, power plant, shipyard, pharmaceutical, dairy, beer, beverage, water conservancy and so on
The inside and outside of the large and small heads are processed with high-grade polishing equipment to meet the requirements of surface precision; This product is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields;
Eccentric heads are those whose centers are not on the same line. Its role is to stick to the wall or stick to the ground pipeline without taking up space, but also to connect two different caliber pipelines, change the size of the flow.
Application of eccentric reducing pipe:
When absorbing water, the water pressure of the suction pipe section decreases, and the gas dissolved in the water will be separated. If the concentric reducing pipe is used, these gases can not be discharged in time, and will accumulate and block at the protrusion, forming a gas resistance. The pump will also appear noise and water delivery can be greatly reduced. If the partial reducer is used, the separated gas will be discharged in time, and it will not constitute an air resistance. When the diameter of the pipe itself is not big, the difference between the front and rear pipe diameters is not big, the concentric reducer may be used, the air resistance appearance is not so significant, and the pressure change in the suction process of the self-priming type is not so big, so the damage is not shown.

Now we are not on the eccentric reducer has a good understanding of it, its role is very big, and the use is also very wide, everyone’s mood is not so excited like Xiaobian, sigh that this is really a very great tool! If you are interested, you can further understand the concentric reducer. Xiaobian believes that it will be very magical and its role will be great. Now that you have a good understanding of eccentric reducers, it’s time to apply them to your life and let them play their role to the limit!
