Three is a pipe, pipe connecting piece. Also called pipe three or three pieces, three joints, in charge of road to branch.
Three with equal diameter and different diameter of points, such as track three of the end part of the connecting pipe are of the same size; reducing the three supervisor over the same size, and the branch pipe size less than competent nozzle sizes.
Three is used for pipeline branches of a pipe. The seamless pipe manufacturing, three, now commonly used technology of hydraulic bulging and hot forming two.
A. Hydraulic bulging
Three way hydraulic bulging through metal material compensation axial expansion pipe of a forming process. The process is the use of special hydraulic machine, with three equal diameter tube filled with liquid through the hydraulic machine, the two lateral cylinder synchronization of movement extrusion billet, billet is extruded by smaller, the liquid in the tube with the tube has a smaller volume and pressure, when the reach three way pipe bulging out of the required pressure, metal materials in the cylinder and tube under the action of liquid pressure in the mold cavity flow along the expansion pipe.
Three way hydraulic bulging process can be shaped at a time, higher production efficiency; three head and shoulder increased wall thickness.
For seamless three hydraulic bulging process equipment required larger tonnage, currently used mainly for less than DN400 standard wall thickness three manufacturing. The application of forming material for cold hardening tendency of relatively low carbon steel, low alloy steel, stainless steel, including some non-ferrous metal materials, such as copper, aluminum, titanium and other.
B. Hot forming
Three hot forming is greater than three the diameter of the tube, compressed approximately to three of the size of the diameter of the branch pipe parts drawing, a hole is opened; tube by heating, into the mold, and the tube is mounted within the tensile pipe die; under the action of the pressure tube is radially compressed radial compression, in the process of metal to the branch direction of flow and in die drawing forming a branch. The whole process is through the tube radial compression and the branch pipe parts of the drawing process and forming. Hydraulic bulging with three different is, hot three branch metal is formed by tube radial motion compensation, so it is also called the radial compensation technology.
Due to the adoption of heated press three, the material forming the required equipment tonnage reduction. Hot three links on materials adaptability wide, suitable for low carbon steel, alloy steel, stainless steel materials; particularly in large diameter and thick wall three, usually used in the forming technology.
1 materials to partition carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, PVC etc..
2 with the production method can be divided into pushing, pressing, forging, casting and other.
3 in order to create a standard can be divided into GB, electric standard, standard, standard, American Standard, German standard, Japanese standard, the standard, as follows: GB / T12459, GB / T13401, ASME, B16.9, SH3408, SH3409, SH3410-96, HG / T21635, DL / T 695, SY / T 0510, DIN 2615.
