Product Name：Carbon Steel Welding Neck Flange
Butt welding flange is a kind of pipe fitting. It refers to the flange with neck, which has a round pipe and is connected with the pipe by butt welding. Butt welding flanges are not deformed
The butt welding flange is not easy to deform, well sealed and widely used. It has corresponding rigid and elastic requirements and reasonable butt welding thinning transition. The distance between the welding junction and the joint surface is large, and the joint surface is free from welding temperature deformation. It adopts a relatively complex horn shape structure, which is suitable for pipelines with large pressure or temperature fluctuations or pipelines with high temperature, high pressure and low temperature. It is generally used for pipelines with PN greater than 2.5MPa Pipeline and valve connection; also used to transport expensive, flammable and explosive media pipeline.

Q:What is the lead time?
A: Normally speaking, it asks for 20-40 days for mass production except during busy seasons.
Q: Do you develop any new designs every year?
A: Yes, our design department will develop new items according to the market trends each year.
When welding carbon steel flanges, they are repeatedly heated to separate out carbides, which reduces the drop resistance and mechanical properties. The welding electrodes should be connected monotonically. Titanium calcium type should be monotonous at 150℃ for 1 hour, low hydrogen type should be monotonous at 200-250℃ for 1 hour (do not dry repeatedly, otherwise the coating will crack) Viscous oil and other dirt will prevent the weld from increasing carbon content and affect the weld quality.
Carbon steel flanges have a great impact on the machinery industry and have made important contributions to economic growth. The forging process of carbon steel flanges can be divided into phase change forging, roll forging, rotary forging and forging. Therefore, we must pay attention to the growth of carbon steel flanges to adapt to the growth trend of the ancient industry and the world's carbon steel flange forging industry. The phase change forging, phase change forging and ring rolling of carbon steel flanges can undergo the forging process.
In order to improve the utilization rate of materials, rolling and cross rolling can be used for the processing of elongated materials, so it is difficult to ensure the accuracy of forging. The consumption of carbon steel flange blanks in cold forging will cause deformation and work hardening, which will make the forging die bear high load. Therefore, it is necessary to use high-strength forging dies during the forging process and avoid wear and adhesion. Hard lubricating film needs to be processed.
In addition, in order to avoid cracks in the carbon steel flange blanks, a central annealing process is also required. This improves the deformation resistance of the carbon steel flange. Carbon steel flanges are selected with flanges, steel rings, flanges, etc. are set at the pipe end, and the flange may be free at the pipe end of the flange. Therefore, it is necessary to use a computer to control the purpose of the forging die and change the forging process, and then a forged product with chaotic shapes and high precision can be obtained with a lower forging force.
