According to the formal national standards, the flat welding flange with neck should be the flat welding flange product with neck, because some customers may not be clear and see or think of adding a small short neck on the flat welding flange, resulting in the name of flat welding flange with neck or flange with neck, which is abbreviated as so flange in English.
Characteristics of flat welding neck flange
Because the flat welding flange with neck has a small short neck than the flat welding flange, which is commonly known as the flange piece, it greatly enhances the stiffness of the flange and improves the bearing capacity of the flange.
The flat welding neck flange not only saves space and reduces weight, but also ensures that there will be no leakage at the joint. Moreover, the flat welding neck flange has a variety of sealing surface types and good sealing performance;
Specifications and parameters
DN15-DN1000
Sealing surface type
Raised surface (RF), full plane (FF), concave convex surface (MFM), concave surface (FM), convex surface (m), tenon and groove surface (TG);
The concave convex surface (MFM) belongs to supporting use;
Common materials
Carbon steel, alloy steel, stainless steel.
Executive standard for flat welding neck flange HG/T20592~20635-2009 GB/T 9116-2010
There are also American Standard, German standard, Japanese standard and other national standards with neck flat welding flange products.
Connection form
The welding method is the same as that of flat welding flange. It is welded on one side and fastened with double bolts.
Production process
Pure material forging, high precision lathe processing.
Advantages and disadvantages of flat welding neck flange
Advantages: the flat welding flange with neck also belongs to the flat welding flange. Because it has a short neck, the strength of the flange is improved and the bearing strength of the flange is improved, so it can be used on higher pressure pipelines;
Disadvantages: the cost is higher than that of plate flat welding flange, and it is easier to bump during transportation due to its shape characteristics;
Procurement proposal
1: It is recommended to purchase from a regular flat welding flange manufacturer with a certain production scale;
2: The flange manufacturer needs to provide the material test report and other relevant data of the flat welded flange with neck;
3: The flat welding flange with neck shall be stamped and marked with corresponding specification and model;
Flanges include: forged steel flanges of carbon steel, alloy steel, low-temperature steel, stainless steel, dual phase steel and nickel base alloy, steel forgings for various boilers and Pressure Vessels, as well as various machinery and ship forgings.
Flange plates include plate flat welding flange, butt welding flange, neck flat welding flange, neck butt welding flange, loose sleeve flange, large mechanical flange, pressure vessel flange, socket flange, screw flange, flange cover, spectacle blind plate, pipe plate, plug, manhole, wind power flange, pipe flange and CNC precision flange.
