Stone Fire Tube
Four - way for pipe fitting, pipe connector.Also called pipe fitting four or four - way pipe fitting, four - way joint, used in the main pipe to branch pipe.
The four passes are divided into equal diameter and reducing diameter. The pipe ends of the four passes are of the same size.The pipe size of the four - way pipe is the same, while the pipe size of the branch pipe is smaller than the pipe size of the pipe.A four - way is a pipe fitting for pipe branches.
Folding hydraulic bulging
Four-way hydraulic bulging is a forming process of expanding branch pipe by axial compensation of metal material.The process is to use special hydraulic press, will be equal and cross welding cross diameter of 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.Four - way hydraulic bulging process can be formed in one time, high production efficiency;There was an increase in the wall thickness of the main part and the shoulders.Due to the large tonnage of equipment required for seamless four-way hydraulic bulging process, it is mainly used for four-way manufacturing of standard wall thickness less than DN400 in China.The suitable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low hardening tendency, including some nonferrous materials, such as copper, aluminum and titanium.
Folding and hot pressing
Four-way hot pressing is to flatten the tube billet which is larger than the four-way diameter to the size of the four-way diameter, and open a hole in the part of the stretching branch pipe.The tube billet is heated, put into the forming die, and in the tube billet is loaded with the drawing die;Under the action of pressure, the tube billet is compressed radially. In the process of radial compression, the metal flows towards the direction of the branch pipe and forms the branch pipe under the drawing of the die.The whole process is formed by the radial compression of the tube billet and the drawing of the branch tube.Different from the hydraulic bulging four-way, the metal of the hot-pressed four-way branch pipe is compensated by the radial movement of the tube billet, so it is also called radial compensation process.
Due to the use of heating after pressing the four - way, the material forming equipment tonnage is reduced.The hot-pressed four-pass has a wide adaptability to materials, suitable for low carbon steel, alloy steel, stainless steel materials;In particular, large diameter and wall thickness of the four - way, usually used this forming process.
1. Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon mold, PVC, etc.
2. According to the production method, it can be divided into top, pressing, forging, casting, etc.
3. To make standard classification can be divided into the national standard, the electric standard, water standard, American standard, Germany standard, Japanese standard, the standard, etc., specific as follows: GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, DL/T 695, SY/T 0510, DIN 2615
