Hot pressing is to flatten the pipe billet larger than the diameter of the tee to the diameter of the tee. Cold drawing tee opens a hole in the part of the stretch branch pipe.The tube billet is heated, put into the forming die, and the punching die of the stretch branch pipe is loaded into the tube billet;Under the action of pressure, the tube billet is compressed radially. In the process of radial compression, the metal flows towards the branch tube and forms the branch tube under the stretching of the die.The whole process is formed by the radial compression of the tube billet and the stretching of the branch tube.Different from the hydraulic bulging tee, the metal of the hot pressing tee is compensated by the radial movement of the tube billet, so it is also called radial compensation process.
3. Stitching and forming
Use short pipe welding (or bonding) to form, save material, reduce cost.However, it is necessary to ensure the reliability of the welding (or bonding) process, and make corresponding joint inspection when necessary, such as pressure test, flaw detection, magnetic powder, etc.
4. Forging forming
Because of the limitation of equipment and processing conditions, forging tee is generally of small caliber.Processing costs are relatively high.
The tees are pipe fittings and pipe connectors.Also called pipe fitting tee or tee, tee joint, used in the main pipe to branch pipe.
The tee is divided into equal diameter and reducing diameter. The joint end of the tee is of the same size.The main pipe size of the reducing tee is the same, while the branch pipe size is smaller than that of the main pipe.
A tee is a pipe fitting for a pipe branch.For the use of seamless pipe manufacturing tees, the current commonly used technology is hydraulic bulging and hot forming two kinds.
