Four-way pipe fittings, pipe fittings, also known as four-way pipe fittings, four-way joints, used in the main pipe branch pipe.

Si-tong can be divided into isometric diameter and reducing diameter. The nozzles of si-tong are of the same size. The main pipe size of the reduced four-way is the same, while the branch pipe size is smaller than the main pipe size. Four - way is a kind of pipe fitting used for pipe branch.

Hydraulic bulging

Hydraulic bulging of four-way pipe is a forming process which compensates the bulging of branch pipe through the axial compensation of metal material. The process is to use special hydraulic press, will be equal and cross diameter tube billet inside the injection liquid, through the two horizontal side of the hydraulic cylinder synchronization of the motion of tube billet, billet after squeezed smaller volume, smaller volume of liquid with the tube billet inside the tube billet and the pressure increases, when the four-way pipe bulge out to the pressure, the metal material in the liquid in the cylinder and the pipe pressure under the dual role of flow along the mold cavity and the branch pipe. The hydraulic bulging process of four-way can be formed in one time, and the production efficiency is higher. The wall thickness of the head and shoulder of si tong increased. Due to the large tonnage of equipment required by the hydraulic bulging process of seamless four-way, it is mainly used in the manufacturing of standard four-way wall thickness less than DN400 at present. The suitable forming materials are low carbon steel, low alloy steel and stainless steel, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc.

thermoforming

Hot pressing is to flatten the blank larger than the diameter of the four-way to the size of the diameter of the four-way, and open a hole in the part of the extension branch. The tube billet is heated and put into the forming die, and the punching die of the tensile branch tube 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 pipe and forms the branch pipe under the stretching of punching die. The whole process is formed by the radial compression of the tube billet and the stretching of the branch part. Different from hydraulic bulged four-way, the metal of hot-pressed four-way branch pipe is compensated by the radial movement of the tube billet, so it is also called radial compensation process.

As a result of the use of heating after pressing the four, material forming equipment required by the tonnage reduction. Hot pressing sitong has wide adaptability to materials, suitable for low carbon steel, alloy steel and stainless steel. Especially the big diameter and thick tube wall of the four - way, usually using this forming process.

1. Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon brick, PVC, etc.

2. It can be divided into top making, pressing, forging, casting, etc.

3. Manufacturing standards can be divided into national standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.
