Product Name：Alloy Steel Socket Welding Flange
Socket welding flange refers to the flange welded at the pipe end and outside when the pipe end is inserted into the flange ring ladder. There are two kinds with and without neck. The flange with neck has good rigidity, small welding deformation and good sealing performance. It can be used in the situation with pressure of 1.0 ~ 10.0MPa. B flange for vessel is also socket welding flange, which is used in the occasion with high sealing requirements. During design, socket welding flange can be checked as integral flange.

Flange manufacturers analyze the characteristics of alloy flanges
The high-pressure alloy flange is a circle of disc connected to the end of the pipe or cylinder and the head. Several bolt holes are evenly distributed on the disc. The material is high-pressure alloy. Commonly used important parts.
A container flange with a certain nominal diameter is suitable for a container with a certain nominal diameter. Similarly, a pipe flange with a certain nominal diameter is suitable for pipes and fittings with a certain nominal diameter. Therefore, the dimensions of the vessel flange and pipe flange of the same nominal diameter are different. The two cannot be substituted for each other. When pipes are used as containers, pipe flanges are used.

What is the use of stainless steel flange solution treatment?
1. It is mainly to improve the plasticity and toughness of steel and alloy, and prepare for precipitation hardening treatment.
2. Make the structure and composition of stainless steel uniform: the atomic activity intensifies at high temperature, the σ phase dissolves, the chemical composition tends to be uniform, and a uniform single-phase structure is obtained after rapid cooling.
3. Fully dissolve the various phases in the alloy, strengthen the solid solution, improve toughness and corrosion resistance, eliminate stress and soften, so as to continue processing or forming.
4. Eliminate work hardening to facilitate continued cold working. Through solution treatment, the distorted crystal lattice is restored, the elongated and broken crystal grains are recrystallized, and the internal stress is eliminated.
5. Restore the inherent corrosion resistance of stainless steel. The precipitation of carbides and lattice defects due to cold working reduce the corrosion resistance of stainless steel. The corrosion resistance of stainless steel is restored to a good state after solution treatment.
[Solid solution treatment] refers to the heat treatment process of heating the alloy to a high temperature single-phase zone to maintain a constant temperature, so that the excess phase is fully dissolved in the solid solution and then rapidly cooled to obtain a supersaturated solid solution.
