Application scope and connection points of alloy high-pressure flange

{1} Scope of use of national standard high-pressure flanges

After the production of the national standard high-pressure flange is completed, the final process is to apply anti rust oil on the surface of the national standard high-pressure flange, with the intention of preventing rust stains from appearing on the national standard high-pressure flange after touching water, which affects the appearance of the product.

Welding high-pressure flanges are suitable for connecting steel pipes with a nominal pressure not exceeding 2.5 MPa. The sealing surface of the rolled national standard high-pressure flange can be divided into three types: smooth, concave convex, convex tongue, and groove. The other two types of rolled national standard high-pressure flanges are also relatively common in use.

National standard high-pressure flange is one of the national standard high-pressure flanges, widely used and popularized in the machinery industry, and has been well received and favored by users. National standard high-pressure flanges have a wide range of applications and their usage scope is determined based on different characteristics. They are mainly used for medium conditions, such as low-pressure unpurified compressed air and low-pressure circulating water.

National standard high-pressure flanges include many types and models. Welded steel national standard high-pressure flanges are used for butt welding of national standard high-pressure flanges and pipelines. They are mainly used for welding technology. They have good performance characteristics and performance. It has a reasonable structure, high strength and stiffness, can withstand high temperature and high pressure, repeated bending and temperature fluctuations, and has sealing performance. The rolling national standard high-pressure flange with a nominal pressure of 2.5MPa adopts a concave convex sealing surface.

When we manufacture national standard high-pressure flanges, the main purpose of manufacturing national standard high-pressure flanges is reflected in the above points. We all need to manufacture national standard high-pressure flanges according to the correct production methods.

{2} How are carbon steel high-pressure flanges and fasteners connected

Carbon steel high-pressure flange is a type of carbon steel high-pressure flange widely used and promoted in the mechanical industry, receiving high praise and recognition from users. The use of carbon steel high-pressure flanges is universal, and the application scope is determined based on different characteristics. It is mostly used in situations where the medium is relatively relaxed, such as low-pressure non polluting compressed air and low-pressure circulating water. Its advantage is that it is relatively inexpensive. The rolled carbon steel high-pressure flange is used for connecting steel pipes with a nominal pressure not exceeding 2.5MPa. The sealing surface of the rolled carbon steel high-pressure flange can be made into three types: lubricating, concave convex, and mortise and tenon groove The utilization of lubricated rolled carbon steel high-pressure flanges is significant, and the other two methods of rolled carbon steel high-pressure flanges are also widely used in applications. There are many varieties and models of rolled carbon steel high-pressure flanges. Welded carbon steel high-pressure flanges are used for the butt welding of carbon steel high-pressure flanges and pipes, and are important in welding techniques. They have good application characteristics and functions, with a reasonable structure, high strength and stiffness, and can withstand high temperature and high pressure, repeated twists and turns, and stable temperature. The sealing performance is reliable. The rolled carbon steel high-pressure flange with a nominal pressure of 0.25-2.5MPa adopts a concave convex sealing surface. The environment for the important utilization of rolled carbon steel high-pressure flanges is suitable, and it is necessary to determine the detailed application value and function of carbon steel high-pressure flanges based on the specific situation, which can withstand high temperature and high pressure.
