Raised Flange
10 month ago
Product details
Raised flange usually refers to a special flange with the function of increasing the height or length of the connection part. Its main functions and descriptions are as follows:
Compensate for the height difference between the connected parts
In the connection of industrial pipeline systems or equipment, when there is a certain height difference between the two connected parts, the use of raised flanges can effectively make up for this gap, so that the pipelines or equipment can be smoothly connected, ensuring the continuity and stability of the entire system.
For example, in some large chemical plants, the connection between reactors and conveying pipelines at different heights, the raised flange can adjust the connection height according to actual needs, so that the pipeline can accurately dock with the interface of the reactor, avoiding problems such as connection difficulties or stress concentration caused by height differences.
Easy to install and maintain
The raised flange can provide more convenient operating space for installers without changing the original pipeline or equipment layout, making it easier to tighten bolts and replace gaskets, thereby improving the efficiency of installation and maintenance and reducing work difficulty and labor intensity.
For example, in some narrow spaces, if the pipeline connection is directly connected, it may lead to insufficient operating space, while the use of raised flanges can raise or extend the connection part to a more convenient position, which is convenient for installers to carry out construction and subsequent maintenance and repair work.

Buffering the stress of pipeline system
When the pipeline system is subjected to thermal expansion and contraction, vibration or other external forces, certain stress will be generated. The raised flange can play a role of buffering and compensation to a certain extent, reduce the impact of stress on the pipeline connection parts, and reduce the risk of pipeline leakage or damage.
For example, in a long-distance steam pipeline transportation system, due to the high temperature of steam, the pipeline will produce large displacement and stress due to thermal expansion and contraction. The raised flange can absorb and relieve these stresses through its own structural characteristics and flexible connection, and protect the connection integrity of the pipeline.
Changing the flow direction or connection method of fluid
In some complex pipeline systems, it is sometimes necessary to change the flow direction of the fluid or adopt a special connection method. The raised flange can be used in conjunction with other pipe fittings (such as elbows, tees, etc.) to achieve flexible control of the flow direction of the fluid and diversified connection requirements.
For example, in the pipeline network of some petrochemical plants, in order to enable the fluid to flow accurately to each reaction unit or storage equipment according to the process requirements, the raised flange can be used in combination with elbows of different angles to construct a complex and precise pipeline flow path.
Adapt to special environmental requirements
In some special working environments, such as the presence of corrosive media, high temperature, high pressure and other conditions, the riser flange can be specially selected and designed according to the specific environmental requirements to meet the safe and stable operation of the pipeline system in harsh environments.

For example, in the oil production system of the offshore platform, due to the strong corrosiveness of seawater, the riser flange is usually made of special alloy materials that are resistant to seawater corrosion, and has good sealing performance and strength to ensure long-term reliable use in the marine environment.
The riser flange is usually composed of flanges, short sections and connecting bolts. There are many structural forms, such as plate-type riser flanges, neck-type riser flanges, etc., which can be selected according to different use requirements.
