Most Commonly Used Types of Stainless Steel Flanges
Stainless Steel Flanges are important in the industrial world. Flanges are used by many industries particularly those that use pipelines or plumbing. They are vital for connecting pipeline channels, reinforcing structures in construction zones as well as in the function of equipments. Flanges come as a collar or ring with holes around its perimeter. These holes are where bolts are inserted when assembling the pipeline. They are welded or screwed at the ends of pipes and tubes to allow connection. Steel flanges can be adapted to the specific requirements of a project. In case the pipeline needs to be changed or redirected, the flange can be easily replaced to suit the new pipeline channel. For long distance pipe channels, flanges add to the strength of the pipeline allowing the entire channel to withstand the internal and external pressure constantly exerted on it.
There are various types of Flanges, each with unique uses. Below are some of the most common flanges used by different industries:
1. Anchor flanges: This type of flange is a forged fitting used to avoid axial movement of pipes or tubing. Normally, it is embedded into a concrete foundation or attached in a drag anchor to prevent or minimize pipe movement. These flanges are welded at the ends of pipes and are a very important part of the pipeline. Anchor flanges are specifically designed to carry the pipeline loads. They are especially used at crossings or portions where there are changes in direction.
2. Split flanges: Split Flanges are perfect for use with pre-existing piping. It is composed of two interlocking components that can be securely bolted or weld together. Split flanges are more commonly applied on portions that are weakened and need reinforcement. It can also be used to add a new attachment, especially if other flanges cannot be possibly applied.
3. Expander flanges: This welding neck pipe flange is used if a wider size pipe is to be connected at the flange connection. It is a more cost-effective option than using a combination of reducer-welding neck flange. Aside from cost-effectiveness, expander flanges also help save space because of their compact size. Only one butt-weld is used when installing this flange.
As with any other commodity, Stainless Steel Flanges should meet the standards set by regulation authorities. Here in the United States, flanges that are released to the market are judged under the ASME standard. Although most of the industrial products sold in the market are ASME compliant, there are also substandard materials that find their way to the market. Therefore, you should be sure to work with a trustworthy and reliable manufacturer. There are many stainless steel products manufacturers in the US that provide high-quality items. When choosing your manufacturer, you want to be sure that their production complies with the ASME standards. You should also check whether the company manufactures the specific type and size of flange that you will need for your project.
