Butt welding flange refers to the flange with neck and round pipe transition and butt welding connection with the pipe. Butt-welded flanges are suitable for pipelines with large fluctuations in pressure or temperature, or high-temperature, high-pressure, and low-temperature pipelines. They are also used to transport expensive, flammable and explosive media. Butt-welded flanges are not easy to deform, have good sealing, and are widely used. The nominal pressure PN is about 16MPa. Flat Welded Flange A flange connected to a device or pipe through a fillet weld. Single-sided welding, double-sided nut connection. Beautiful appearance, smooth surface, acid and alkali resistance, anti-corrosion, strong texture performance.

4.skills requirement

1. the level of butt welding flange and its technical requirements shall meet the corresponding requirements of JB4726-4728. 1. Carbon steel and austenitic stainless steel forgings with a nominal pressure PN of 0.25MP-1.0MPa are allowed to use Grade I forgings.
2. Except for the following requirements, forgings with nominal pressure PN of 1.6MPa-6.3MPa shall meet the requirements of Grade Ⅱ or above grade forgings.
3. Those who meet one of the following conditions shall meet the requirements of III and forgings: (1) forgings for flanges with nominal pressure PN ≥ 10.0MPa; (2) chrome-molybdenum steel forgings with PN> 4.0MPa; Ferritic steel forgings with pressure PN> 1.6MPa and working temperature ≤-20 degrees Celsius.

Second, butt welding flanges are generally made by forging or forging. When using steel plates or sections, the following requirements must be met:

5.Processing technology


1. Butt-welded flanges should be ultrasonically inspected without layering defects;
2. It should be cut into strips along the rolling direction of the steel, bent and welded into a ring, and the surface of the steel should form a circular cylindrical surface. It is not allowed to machine the steel plate directly into a butt-welded flange with a neck;
3. The butt welds of the ring shall be full penetration welds;
4. The butt welds of the ring shall be heat treated after welding and 100% ray or ultrasonic inspection shall be performed, and the ray inspection shall meet the Class II requirements of JB4730, and the ultrasonic inspection shall meet the Class I requirements of JB4730.

5.the outer slope of the neck of the butt welding flange should not be greater than 70 °. Butt welding flanges strictly control technical parameters during production and welding to ensure that they can fully play their role and value in production and use.
