The introduction of the size of the head

Reducer reducer is also called reducer, reducer, reducer straight through. One of the chemical pipe fittings used for the connection between two pipes of different diameters. According to the different shapes, it is divided into two kinds: concentric size head and eccentric size head. The material of the large and small head includes stainless steel large and small head (304304 l316316l), alloy steel, carbon steel large and small head, and the material of the large and small head is No. 20 steel, Q235, Q345, 16Mn, etc.

Fabrication Process of Tee

Fabrication Process of Tee

The hydraulic bulging of the tee is a forming process in which the branch pipe is expanded by the axial compensation of the metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. After the tube blank is squeezed, the volume of the tube blank becomes smaller, and the pressure of the liquid in the tube blank increases as the volume of the tube blank becomes smaller. When the pressure required for the expansion of the tee branch pipe is reached, the metal material flows along the mold cavity under the dual action of the liquid pressure in the side cylinder and the tube blank and expands out of the branch pipe.

What are the three links?

Tee, also known as tee fittings or tee fittings, tee joints, etc. Mainly used to change the direction of the fluid, used in the main pipeline to branch pipe. Can be classified by pipe diameter. Generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, PVC and other materials.

Pressing Elbow Production Process Introduction and Application Analysis

Pressing Elbow Production Process Introduction and Application Analysis

The manufacturing process of stamping elbow first welds a polygonal ring shell with a polygonal cross section or a polygonal fan shell with closed ends. After the inside is filled with pressure medium, internal pressure is applied. Under the action of internal pressure, the cross section gradually changes from polygonal to circular and becomes a circular ring shell. According to needs, a circular ring shell can be cut into 4 90 elbows or 6 60 stamping elbows or other specifications of stamping elbows. This process is suitable for manufacturing large elbows of any specification with a ratio of middle diameter to inner diameter of stamping elbows greater than 1.5. It is an ideal method for manufacturing large carbon steel elbows at present. Stamping elbows are suitable for piping systems in the oil, gas, chemical, hydropower, construction and boiler industries. No tube blank as raw material, can save pipe equipment and mold costs, and can get any large diameter and relatively thin wall thickness of carbon steel elbow.

Matters needing attention in stamping elbow processing

Matters needing attention in stamping elbow processing

Stamping elbow processing is a production technology that uses the power of regular or special stamping equipment to directly deform the sheet metal in the mold and deform it, so as to obtain a certain shape, size and performance of product parts. Precautions in processing Good production technology. Sheet metal, mold and equipment are the three elements of stamping processing, in the production should pay attention to good use and cooperation. Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to the material forming engineering technology.

What are the outstanding advantages of stamping elbow

What are the outstanding advantages of stamping elbow

1. Development trend of stamping elbow pipe: The raw material of stamping elbow not only has qualified creep breaking curve, but also has moderate price of pipe. The construction is convenient and fast compared with other varieties. The connection form belongs to the reliable local mutual melting connection form at this stage. The aperture of the pipe fitting part is larger than the inner diameter of the pipe of the same specification. In the system, the fluid resistance of the system is relatively small because there is no mechanical connection mode of local diameter reduction. 2. Long-term pressure resistance, only from the design stress, the pressure resistance of the national standard stamping elbow is good. However, due to various factors, the actual wall thickness of the floor heating pipe is usually 2mm. In this wall thickness, all kinds of pipes can meet the requirements of floor heating, stamping elbow pipe pressure advantage can not be reflected;
