Welding Neck Flange (Code SO)

The full name is “Welding Neck Flat-Face Flange,” designated as SO. Its defining feature is its short-neck structure; after the pipe is inserted into the flange’s neck opening, it is connected by a flat weld (with the weld located on the outer side of the flange neck).

Inquiry Inquiry

Welding Neck Flange (Code WN)

The “welding-neck flange,” designated as WN, is one of the commonly used types of flanges. It is characterized by a short, tapered neck that is welded to the pipe using a butt-weld connection.

Raised Face (RF) Flange

The sealing type “Raised Face to Raised Face (RF-RF)” is one of the commonly used mating configurations for flange sealing surfaces, and it applies to plate-type flat-welded or butt-welded flanges.

Inquiry Inquiry

Threaded flange

The flange center is equipped with internal threads, allowing it to be connected to pipes with external threads of the corresponding specifications. The connection process does not require welding, making it suitable for piping applications where welding operations are restricted or where convenient installation is desired.

Inquiry Inquiry

Full-Flange (FF) Flange

It adopts a full-flat (code-named FF) sealing surface design, with a mating configuration of full-flat-to-full-flat combination (i.e., FF—FF).

Inquiry Inquiry

Plate-type flat-welded flange (code PL)

This is a common pipe fitting that is securely fastened to the pipeline by welding and connected via bolts and gaskets. It is suitable for low-pressure piping systems in fields such as chemical engineering and petroleum. The 304 stainless steel material offers excellent corrosion resistance.

Inquiry Inquiry

Flat-welded flange

In terms of application scope, these components are used in pressure piping systems and pressure vessel equipment in fields such as petrochemicals, power generation, water supply and drainage, HVAC, and shipbuilding. They represent a common and fundamental component in industrial piping connections.

American Standard Welding Flange

A flange is a disc-shaped connecting component commonly used on pipelines, vessels, or equipment. It is typically employed in pairs and combined with gaskets and bolts to form a detachable connection assembly. Its primary function is to provide a secure connection and seal between various components of the system, facilitating the installation, inspection, or maintenance of specific sections.
