The manufacturing process of the vacuum tees for telescopic welded bellows. The so-called randomness does not form a circle, and the production of vacuum tees seems to be the same. The vacuum tee must be carried out in strict accordance with the process and rules in the production. Only in this way can the quality of the vacuum tee be guaranteed. The geometric dimensions of the vacuum tee include outer diameter, inner diameter, and wall thickness. During the production process, these parameters must be based on The standard size is strictly implemented. Most of the vacuum tees are used for welding, so for the convenience of welding, we use the same raw materials for making the vacuum tees and the pipes to be welded together. All the vacuum tees must be treated with shot blasting of the oxide scale on the inner and outer surfaces, and then coated with anti-corrosion paint. After the pipe is put in, the pipe is locked with a hydraulic cylinder, and then liquid is injected to both sides to make it bulge inward, extrude the pipe into the convex shape of the tee, and then cut the protrusion from the appropriate position to beveled . In this process, two shot peening treatments are required. In order to improve the welding quality of the vacuum tee, we have beveled the ends to leave a certain angle. This industry requires a lot. There are strict regulations on the edge thickness and the angular deviation range. In addition, due to work hardening during processing, heat treatment is also required. Another point is the packaging requirements for the vacuum tee. For the small-caliber vacuum tee, we have to make a wooden box to place the vacuum tee, about 1 cubic meter, and strictly stipulate that the weight of the tee should not exceed one ton to prevent crushing. For large-caliber vacuum tee, we have to package them individually, which is to facilitate transportation and prevent oxidation by air. The production process of vacuum tee is like this, it is through a strict process, so the quality of the vacuum tee fittings we use is so good.
