Product Description
Large-diameter Flanges
Large-diameter flanges are one type of flanges. They are widely used and promoted in the machinery industry, chemical industry, wind power industry, and sewage treatment industry, and are well received and favored by users. Large diameter flanges are widely used. Large diameter flanges are welded flanges. Large-diameter flanges cannot use threaded connections. In the actual pipeline engineering, the characteristics and advantages of welding large-diameter flange will also be different. Therefore, they must be used in different ranges to ensure that the flanges play an important role.
Large-diameter flange uses
Large diameter flanges are used to connect or block two very large diameter pipes, such as those used for oil and gas pipelines or refinery pipelines.
Custom large-diameter flange features
1. easy to install.
2. Adapt to any climate.
3. Rugged and long life.
4. Anti-corrosion, the flange surface is coated to effectively prevent corrosion and wear.
5. Wide range of applications.
Three types of flange sealing surface
1. Flat sealing surface, suitable for occasions with low pressure and non-toxic media;
2. Concave-convex sealing surface, suitable for occasions with slightly higher pressure;
3. Tongue and groove sealing surface, suitable for flammable and explosive, Toxic media and high pressure occasions.
Flanges of different natures have good product performance in different fields, and the effects of different applications and spaces will be different.
Large-diameter flange production process
The production process is mainly divided into four types: forging, casting, cutting and rolling.
Cast flange and forged flange
1. The cast flange has accurate shape and size, small processing volume and low cost, but has casting defects (pores, cracks, inclusions); the internal structure of the casting is poor in streamline (if it is a cutting part, the streamline is worse);
2. Forged flanges generally have lower carbon content than cast flanges and are not easy to rust. Forgings are streamlined, have a denser structure, and have better mechanical properties than cast flanges;
3. Improper forging process will also cause large or uneven crystal grains, hardening cracks, and forging costs higher than cast flanges.
4. Forgings can withstand higher shear and tensile forces than castings.
5. The advantage of castings is that they can produce more complex shapes and lower costs;
6. The advantage of forgings is that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in the castings.
The model of our company's flange products is Φ820mm-Φ3620mm. Material is carbon steel, stainless steel and alloy steel, etc.
