Boiler 20G Bend Pipe 20G Bend Pipe Boiler Bend Pipe Bend The bender of Jiangdong Power Producer uses a complete set of bending equipment to bend, which is divided into two processes, cold heading and hot pushing. No matter which kind of machine equipment and pipeline, most of them use elbows, mainly used for oil, gas, liquid, engineering bridge construction and so on.

Analysis of the main reasons for the decline in the quality of elbows and methods of attention:

1. In pure bending, the outer arm wall of the neutral layer under the action of the external force distance M is thinned by the tensile stress & 1, and the inner compressive stress. As the effect increases, the combined forces N1 and N2 change the cross section of the tube. Based on this factor, the main reason for the decline in the quality of the elbow is RX and SX. Therefore, in GBJ235-82, the RX value and the thickness of the outer side of the various pressure levels are clearly defined. The purpose is to control RX With the value of SX, thus ensuring quality.

2. As mentioned in the previous article, when the pipe is bent, the outside of the material is stretched, and the position of the neutral pressure on the inner side is different from the method of bending the pipe. When the top bend (compression bending) works, the neutral axis is about 1 / At 3 places, the neutral axis is 2/3 away from the outer wall during the turning (backbending) work. Therefore, the thin-walled pipe is curved, and it is beneficial to use the spiral bending method.

3. The accuracy of curved tires is also one of the factors affecting the quality of curved pipes. In the manufacture of curved tires, in addition to the specifications and dimensions required to be controlled within a certain tolerance range, we also require users to select the corresponding curved tires according to the diameter of the bending pipe when in use.



4. The bendability and surface corrosion of the pipe itself may also affect the quality of the bend. During the construction on site, the operator also needs to know the material of the pipeline being processed, the processing performance and make production judgments on the surface corrosion.

5. R is now available. (Bending radius / outer diameter of tube) Relation curve chart for users to refer to when choosing the relationship between tube diameter and wall thickness. Reflect the influence of the relative bending radius and relative wall thickness on the quality of the bend, according to the acceptance criteria for pipeline processing: cold-formed steel pipes are: medium and low pressure is 4D, high pressure is 5D. Therefore, our curved tire is designed as R = 4D (special circumstances will be determined), so as far as the pipe bender produced by our factory is concerned, the main choice is the relative wall thickness SX. The upper part of the figure is the coreless area and the middle part of the figure. It is a common mandrel region, and the lower part of the figure is a special mandrel region. Because the design and manufacture of special mandrels are very difficult and the operation is not very convenient, we generally do not supply them. Special circumstances can be negotiated separately.

6.Effect of lubrication on product quality during molding:

In the traditional pipe bending production process, enterprises will take many measures in order to obtain better pipe bending surface quality, including: adopting more advanced pipe bending machines, using stronger molds, or using lubricating products and other methods . With the use of pipe benders and high-strength molds, companies often need to invest a very large amount of money to complete them. Only the use of pipe bend lubrication products is relatively inexpensive and quickly meets the requirements of corporate product quality. However, in the traditional production process: oil-based elbow lubrication products can meet the requirements of the quality of elbows in the production of elbows, but the difficult cleaning and environmental pollution of oil-based elbow lubrication products are very prominent. In this way, enterprises must use more methods to eliminate the impact of the use of oil-based elbow lubrication products on the quality of the final product, and invest more energy and funds for this. The arrival of IRMCO elbow water-based grease meets the company's requirements for the quality of elbow products, and can avoid and reduce the increased investment of enterprises because of the use of oil-based elbow lubrication products, completely optimizing the company's production processes.



In the application process of traditional oil-based lubrication products, the production efficiency of enterprises is greatly restricted, because the fluidity and extremely difficult to clean of oil-based lubrication products have caused pollution to the production environment and workers' working conditions, and the company has eliminated These pollutions often cost a lot of money and manpower. Adopting can reduce or even avoid the above-mentioned human and material expenditures for cleaning up pollution, and its characteristics of no-clean and direct welding can greatly improve the production efficiency and product quality of the enterprise. The amount of IRMCO water-based elbow grease can usually reduce the amount of 50-80 compared to traditional lubricants, which can save more costs for enterprises.
