What are the characteristics of large diameter butt welding elbow

Large diameter butt welding elbow is a kind of pipe parts, such elbow has a lot of advantages, but many people do not know this kind of pipe, today we need to seriously understand some characteristics of large diameter butt welding elbow.

Large diameter butt welding elbow not only saves area, but also ensures airtightness. If the sealing aperture of the large diameter butt welding elbow is reduced, then the specification of the flange can be reduced.

In addition, in use, if the large diameter butt welding elbow with small aperture is used, the connecting part of the sealing surface can also be reduced, and then the flange sealing gasket can be replaced with a sealing ring to ensure the degree of adhesion of the sealing surface.

Manufacturing process of large diameter butt welding elbow

Welding elbow in welding, must be welded at the same time in the port of the two product workpiece, generally with resistance welding and flash welding these two types of on-the-spot assembly construction.

Welding elbow is produced according to the hot pressing or calcining process of steel elbow, access method is the connection of elbow and steel pipe, such elbow production rate is high, suitable for the vast majority of engineering projects.

In the case of welding elbow, the external environment of pipe must be cleaned to prevent corrosion in welding

When welding elbows at pipe distribution construction sites, because pipe welding standards are not the same. Therefore, spot welding must be carried out according to the welding grade of piping. The welding standard of piping may be different, which is another characteristic of welded elbows

The above is some common sense about large diameter butt welding elbow. Large diameter butt welding elbow plays a very important role in the use of engineering projects, and the working characteristics of large diameter butt welding elbow are good, and can be applied to all kinds of pipeline environment.

However, it must be understood that the large diameter butt welding elbow has corresponding provisions for the assembly skills. If the welding and assembly process standards can not be strictly guaranteed, there may be leakage. Hope these content can help you better understand the large diameter butt welding elbow.

Characteristics of large diameter butt welding elbow

If carbon dioxide gas is added to the brine, the electricity of the water will be increased, and the corrosion will also be increased. Therefore, the debrine tank should avoid carbon dioxide gas melting into the storage tank.

We can protect the area above the tank with nitrogen or other inert gas to prevent carbon dioxide gas from damaging the quality of the purified water

Carbon dioxide gas is a commonly used chemical substance in the air, which improves the hardness and quenching reliability of carbon steel seamless elbow. Carbon dioxide gas molecules are composed of two oxygen atoms and one carbon atom through chemical bonds. Carbon dioxide gas and oxygen reflect the molecular formula of carbon dioxide gas

At room temperature, it is odorless air, relatively denser than air. It can dissolve in water and react with water to form carbonic acid, but it cannot be burned. Solid carbon dioxide gas is often referred to as dry ice, for the reason that water cannot be touched
