What is a carbon steel flange and how is it installed and used?

 

Carbon steel flange refers to the flange material or the end flange connector whose main material is carbon steel. Its application is more extensive.
The carbon steel flange is tight and reliable. It has two sealing surfaces, and the current ball valve sealing surface materials are widely used in a variety of plastic, sealing, and can achieve a complete seal. Due to the wiping properties of the carbon steel flange during opening and closing, it can be used in media with suspended solid particles. Carbon steel flanges have strong applicability and can be used in different fields. The carbon steel flanges produced by this method are used for insulating carbon steel flanges in long-distance pipelines, stations, etc. with pressures PN≥2.5MPa in oil and gas fields. Apply as it is. Simply change the carbon steel flange to a special grade carbon steel flange and use the same method.

 

 

Carbon steel flanges are used in different places and countries and play different roles and values ​​in different fields. They can help users play an important role and value. In the use of a certain working principle, according to a certain production process and technology production and use, carbon steel flange has a certain working principle in use, carbon steel flange working principle is to use carbon steel flange insulation pad The electrical insulating properties of the sheet and the high-strength insulating mat are performed, and the electric insulation of both sides of the carbon steel flange works. The large-scale carbon steel flanges need to be used in accordance with certain conditions and environments in use.

They are used for different use environments. They are used in accordance with the characteristics and advantages of the use of carbon steel flanges, and can play an important role in use and construction. value.

 

Carbon steel flange installation considerations: The first place to check is the pipe, fittings and aprons. Whether it is qualified and can clean the seal in the socket working surface, the tube can be left open for 20 minutes to achieve the best sealing adhesive. When the best effect is achieved, the aprons pores and cracks should be done for too long or too short. It is necessary to establish a good pipe damage maintenance system.

The aprons and provisions of carbon steel flanges shall be placed in the concave and convex grooves in any direction and with large heads inwards, and the installation shall not be distorted. The inspection shall be conducted negligently. As a result, if a rise occurs, the refined steel ladle must be refined. After being verified to give the top of the package inlet, the long nozzle will be injected into the tundish. The secondary cold forging of the surface is fast for training purposes. This is the cutting form of the flame, and the source of the whole process is different.

 

 

 

Carbon steel flange seals are pre-tightened by bolts to generate sufficient pressure between the gasket and the flange sealing surface. The deformation of the gasket surface is sufficient to fill up the microscopic unevenness of the flange sealing surface, so as to achieve no leakage. . The minimum unit pressing force acting on the gasket to achieve the above purpose is called the specific pressure y. When the pipework is under operating pressure, under the action of the axial force acting on the inner pressure, the two flanges are separated and the bolts will be elastically or plastically deformed, and the pressing force acting on the gasket will be reduced. When the pressing force acting on the effective section of the gasket is reduced to a certain critical value,

the sealing can still be maintained. At this time, the remaining pressing force on the gasket is the effective fastening force of the gasket when the effective fastening is achieved. When the force is below a certain critical value, leakage occurs and the gasket is misaligned. Therefore, the effective fastening force of the gasket must be greater than the operating pressure of the piping. The ratio of the effective fastening force of the gasket to the working pressure of the piping is called the gasket coefficient m. The distance between the two flange sealing surfaces is greater than the initial state in the operating state. At this time, the tightness between the gasket and the flange sealing surface is ensured by the resilience of the gasket. It can be said that in the initial sealing stage, the surface plastic deformation of the gasket fills the surface of the flange sealing surface to determine the micro-unevenness; while in the operating state of the flange seal, the elastic recovery of the gasket plays a leading role.

 

The value and significance of carbon steel flanges are as follows: 1. If a piece of carbon steel flange is used, if a certain section is damaged, then simply replace the piece of pipe, simple and convenient, and do not need to replace the entire pipe system. 2. The use of carbon steel flanged pipe fittings makes it easy to remove a section of the pipe during inspection and inspection of the pipe. This improves the speed and accuracy of the inspection. 3. The use of connected fittings, when it is necessary to close a section of pipe, can be easily operated. Through the above introduction, the presence of carbon steel flanges eliminates many annoyances and does not require much effort.
