How to select the reducing tee?

How to select the reducing tee?

Seamless Eccentric Reducer Manufacturer shares that reducing tee is a kind of tee, branch pipe and the other two diameters of the diverging tee pipe fittings.

As usual in the selection of reducer tee specifications of the moment through the process of drawings to know what pipe, with what pipe fitting, need to understand the typical construction and the implementation of the work resume. For example, for the drainage pipe, we will not accept the reducing tee, even if the branch pipe is smaller than the main pipe, it can only be reduced through the bushing; As to the elbow, requirements, typical to DN100 pipe of the eve of the turn 90 ° bend, can only use two 45 ° elbow.

As usual, the location of reducing tee can also be used as a combination of general tee and reducing tee in principle, but this is wasteful and unnecessary, so it is the best time to choose reducing tee. The diameter difference between the reducer tee and the tee is as follows: for example, the vertical pipe is marked with de110 above and below, and the transverse branch pipe is marked with de75. This is the reducer tee. The same principle of the equal diameter is the same as this. So when we operate the reducing tee, we should operate it according to the actual situation. When we should operate it, we should accept other tee when we should accept other tee.

Flange shall be inspected regularly

Flange shall be inspected regularly

Stainless steel flange connection is the two pipes, pipe fittings or equipment, first each fixed in a flange, between the two flange, plus pad, bolted together to complete the connection. Some pipe fittings and equipment has its own flange, also belongs to flange connection. Stainless steel flange has threaded connection flange and welding flange, it is a kind of disk parts, in pipeline engineering the most common, flange are used in pairs. In pipeline engineering, flanges are mainly used for connecting pipes. In the need to connect the pipeline, all kinds of installation of a flange, low-pressure pipeline can use wire flange, 4 kg above the use of pressure welding flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter are using welding flange, flange thickness of different pressure and connection bolt diameter and number is different. Stainless steel flange will not produce corrosion, pitting, corrosion or wear, is one of the highest strength materials used in the construction of metal materials. Because of its excellent corrosion resistance, stainless steel enables structural components to maintain the integrity of the engineering design permanently.

Flange can not be stored for a long time, should make regular inspection, often on the surface of the exposed processing must be kept clean, remove dirt, neatly stored in the indoor air dry place, do not pile or open storage. Flange ball valve, globe valve, gate valve use, only for full open or full closed, do not allow to do regulating flow, so as to avoid sealing surface erosion, accelerated wear. Flange materials convenient, simple manufacturing, low cost, widely used; But the rigidity is poor, therefore must not be used for supply and demand, flammable, explosive and high vacuum requirements of chemical process piping system and high, extremely harmful occasions. Sealing surface type has plane and protruding surface. Flange simple structure, small size, light weight; Close and reliable, the sealing surface material of the ball valve is widely used plastic, good sealing, and has been widely used in the vacuum system. Easy maintenance, ball valve structure is simple, the sealing ring is generally mobile, disassembly and replacement are more convenient; In fully open or fully closed, the sealing surface of the ball and seat is isolated from the media.

Flange Production Process

Flange Production Process

Production technology is mainly divided into forging, casting, cutting, rolling these four.

Casting flange and forging flange

Cast Flange Exporter shares that Cast Flange, blank shape and size accurate, small amount of processing, low cost, but casting defects (porosity, crack, inclusion); Poor streamlining of the internal structure of the casting (if it is cutting parts, the streamlining is worse);

Forging flanges generally contain less carbon than casting flanges and are less likely to rust. Forgings are streamlined, compact in structure and have better mechanical properties than casting flanges.

Improper forging process will also appear large or uneven grain, hardening crack phenomenon, the forging cost is higher than the casting flange.

Forgings can withstand higher shear and tensile forces than castings.

                                            

The advantage of castings is that they can produce complex shapes with low cost.

The advantage of forgings is that the internal structure is uniform and there are no harmful defects such as porosity and inclusion in the castings.

From the production process difference between casting flange and forging flange, such as centrifugal flange is one of the casting flange.

Centrifugal flange supplied fromCast Flange Manufacturer ,is produced by precision casting method. Compared with ordinary sand mold casting, this kind of casting has much finer structure and much higher quality. It is not easy to have problems such as loose structure, porosity and trachoma.

First of all, we need to know how the centrifugal flange is produced. The process method and product of centrifugal casting for flat welding flange are characterized by the following processing steps:

(1) to the selected raw materials into the intermediate frequency electric furnace steel smelting, the molten steel temperature of 1600-1700 ℃;

(2) the metal mold pre heated to 800-900 ℃ constant temperature;

(3) start the centrifuge, the steps () in the steel injection step () in the preheating metal mold;

(4) casting natural cooling to 800-900 ℃ keep 1-10 minutes;

(5) cool with water to close to normal temperature, take out the casting.

Polished Stainless Steel Technology

The usage rate of stainless steel is becoming more and more popular. The polishing process of stainless steel such as the Stainless Steel Bend,needs to be understood when it is used. The following are the polishing technical points summarized by technical personnel of our company.

1.Basis: visual inspection of the stainless steel, such as whether there is a weld leakage, welding penetration, welding spot depth is not uniform, deviation from the seam is too far, local sag, butt not uniform, whether there are deep scratches, bruises, serious deformation and other defects in this process can not be remedied, if there are defects should return to the last process dressing. If there is no such defect, enter the grinding process.                   

                                               

 2.Rough grinding: grinding stainless steel on three sides with sand belt, remove the welding spot left by the workpiece welding, as well as the collision in the previous process, to achieve the welding round corner preliminary molding, horizontal and vertical plane basically no big scratches, no collision, after this step after the roughness of stainless steel should reach R0.8mm.

3. Semi-fine grinding: grinding the three sides of stainless steel with the sand belt in accordance with the front and back grinding workpiece method, mainly in front of the process of the seam appeared to correct and rough after the impression of further fine grinding, the front process of the impression left to repeat grinding, to the workpiece surface without scratches, the basic bright. The surface roughness of this process shall reach R0.4mm.

4. Fine grinding: the abrasive belt is mainly used to correct the fine lines in the previous step. The grinding method of the Stainless Steel Elbow is the same as above. The goal of this process is to basically disappear the joint between the grinding part and the unpolished part of the stainless steel, and further polish the surface of the workpiece. After grinding in this process, the stainless steel should be close to the mirror effect, and the surface roughness of the workpiece should reach R0.1mm.
