Forged Male Branch Tee

Raw material preparation:

Material selection: According to product requirements, choose a suitable brass alloy, such as H62 brass, to ensure that the finished product has good mechanical properties and corrosion resistance. ​
Cutting: Cutting brass raw materials into billet sizes suitable for forging, usually using sawing or shearing processes to ensure the accuracy of billet size and weight.

Heating:

Use an induction heating furnace or gas furnace to heat the billet to an appropriate temperature range, usually above the recrystallization temperature of brass (about 700-900 ° C), to improve its plasticity and reduce deformation resistance. ​
Strictly control the heating temperature and time to avoid overheating or underheating, in order to prevent material performance degradation or defects. ​

Forging and Forming:

According to product design, high-precision forging molds are usually made of high-strength alloy steel to withstand working conditions of high temperature and high pressure. ​
Place the heated billet in the mold and apply high pressure through a mechanical press or air hammer to allow the brass to flow and fill the mold cavity, forming the desired tee shape. ​
For pipes with complex shapes, multiple forging and intermediate heating processes may be required to gradually approach the final shape and ensure the density of the internal structure.

Cooling:

The forged workpiece is usually cooled by air or water cooling, depending on the material and process requirements. ​
By adjusting the cooling rate appropriately, the generation of internal stress can be reduced to prevent cracking or deformation of the workpiece.

Follow up processing:

According to the needs, the workpiece is annealed, normalized, or solution treated to improve its mechanical and processing properties. ​
Turn, mill, drill, and thread the forged workpiece to ensure dimensional accuracy and surface smoothness, meeting assembly and usage requirements. ​
Polishing, acid washing, electroplating and other treatments are carried out to improve the corrosion resistance and aesthetics of the workpiece, meeting the specific environmental usage requirements.

Quality inspection:

Appearance inspection: Check the surface of the workpiece for defects such as cracks, folds, inclusions, etc., to ensure the quality of the appearance. ​
Dimensional measurement: Use precision measuring tools to check whether the dimensions of the workpiece meet the design requirements. ​
Performance testing: Conduct mechanical performance, hardness, and pressure resistance tests on the workpiece as needed to ensure that it meets the usage conditions.

Through the strict forging process described above, brass pipe fittings can achieve a dense internal structure and excellent mechanical properties, meeting the requirements for use in high-pressure, high-temperature, and corrosive environments. In addition, forging technology also has the advantages of high material utilization, high production efficiency, and good product consistency, and is one of the key technologies for manufacturing high-quality pipe fittings. ​
