Threaded Flanges

Threaded flange is a kind of non-welding flange that the inner hole of the flange is processed into pipe thread and matched with the pipe with thread to realize the connection. It is compared with flat welding flange or butt welding flange, threaded flange has the characteristics of easy installation and maintenance, and can be used in some pipelines where welding is not allowed on site. Alloy steel flange has enough strength, but not easy to weld, or welding performance is not good, can also choose it. However, under the condition that the pipeline temperature changes drastically or the temperature is higher than 260℃ and lower than -45℃, it is recommended not to use it to avoid leakage.

It has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and other basic engineering.

Types of materials for threaded flanges

1. Carbon Steel Threaded Flange
It have good weldability and mechanical properties, and are more effective in low and normal temperatures, which is a more common type of material. It is suitable for some common occasions, such as general industrial equipment, water and other pipeline connections.

2. stainless steel threaded flange
It is highly corrosion resistant, suitable for use in some occasions with high corrosion requirements for materials, such as food, beverage, pharmaceutical, chemical and other industries. Stainless steel threaded flanges need to pay attention to the selection of appropriate models and specifications to ensure a strong and safe connection.

3. Alloy steel threaded flange
They are characterized by high temperature resistance, pressure resistance, abrasion resistance, etc. They are more effective in high temperature, high pressure and strong corrosive environments, such as petroleum, chemical, natural gas, thermal power and other industries. They need to choose different alloy elements according to different working environments in order to achieve the best use effect.

4. Other material types of threaded flanges
In addition to the three common material types mentioned above, there are some other material types used in special environments, such as titanium alloy, nickel-based alloy and other materials. These materials have higher prices and manufacturing difficulties, and are suitable for use in some special environments.

In short, the choice of material types of threaded flanges needs to be determined according to the actual application scenarios and requirements, and a reasonable choice of materials can better ensure the normal operation of industrial equipment.
