Carbon Steel Weld Neck Flange Introduction
Carbon Steel Flanged Socket Welding Flange, also known as necked flat welding flange made of carbon steel, full name Necked Flat Welding Steel Pipe Flange, English abbreviation: Slip-on, short for so flange.
A flanged socket weld is similar to a flat socket weld flange in that it is a type of flange where steel pipes, fittings, etc. are inserted into the flange and connected to equipment or piping through angular welds.
Carbon steel flanged flat welding flanges with pipe diameters ranging from DN10 to DN600.
Flange sealing surface type
Rounded Face (RF), Concave Face (FM), Convex Face (M), Tongue Face (T), Groove Face (G), Full Flat (FF).
Flange pressure class
PN Series PN6~PN40
Class Series: Class150 to Class1500
Carbon steel socket-welding flange material
Carbon Steel Flanges: ASTM A105, 20#, Q235, 16Mn, ASTM A350 LF1, LF2 CL1/CL2, LF3 CL1/CL2, ASTM A694 F42, F46, F48, F50, F52, F56, F60, F65, F70
The most commonly used materials are 20#, Q235, and 16Mn.
Carbon Steel Flanged Socket Welding Flange Manufacturing Process: Pure billet forging, rough forging (second best) for both flanged socket welding flanges and flanged butt welding flanges.
Oxygen furnace blanking, overall forging or finished forging, turning and cutting for shaping, high-precision CNC lathe turning, CNC radial arm drilling for boring.
Advantages and Disadvantages of Carbon Steel Flanged Socket Welding Flanges
Advantages: Necked flat welding flanges are also a type of flat welding flange due to their short neck, which enhances the flange's strength and improves its load-bearing capacity. Therefore, they can be used on pipelines subject to higher pressure.
Disadvantages: More expensive than plate-type butt-welding flanges, and more prone to dings during transportation due to its shape characteristics.
Procurement Recommendations
1: Recommend purchasing from a reputable颈平焊法兰 manufacturer with a certain production scale.
2: Manufacturers of flanges are required to provide material inspection reports and related documents for necked butt-welding flanges.
3:颈平焊法兰 must have corresponding specifications and model stamps and markings.
