Description
Reducing Tee Straight Tee
Stainless steel tees are pipe fittings and pipe connectors. For branch pipes of the main pipeline. Stainless steel tee is divided into equal diameter and reduced diameter. All three-way ends with the same diameter have the same size. The main pipe size of the reduced diameter tee is the same, but the branch pipe is smaller than the main pipe. The hydraulic bulging process of the stainless steel tee can be formed at one time, which improves the production efficiency. Increased the thickness of the shoulder wall of the main pipe and the stainless steel tee.
Stainless steel tee is a kind of pipe fittings used in pipeline branches. When using seamless pipes to make tees, the usual processes used are hydraulic bulging and hot pressing. The hydraulic expansion of a stainless steel tee is a forming process in which the branch pipe is expanded by axially compensating the metal material. In this process, a special hydraulic press is used to inject liquid into the tube blank with the same diameter as the tee, and the tube blank is squeezed by the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The liquid pressure increases as the volume of the tube decreases. When the pressure required to expand the stainless steel three-way 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 branch pipe, thereby expanding the branch pipe.
The hydraulic convex process of the stainless steel tee can be formed at one time, thereby improving the production efficiency. The wall thickness of the main pipe and the shoulder of the stainless steel tee will increase. Stainless steel tees are pipe fittings and pipe connectors. For branch pipes of the main pipeline. Stainless steel tee is divided into equal diameter and reduced diameter. All three-way ends with the same diameter have the same size. The main pipe size of the reduced diameter tee is the same, but the branch pipe is smaller than the main pipe.
Working principle of stainless steel tee
Stainless steel tee is a pipe fitting used for pipe branching. The current manufacturing process of seamless pipe tee joints includes hydraulic expansion and hot pressing. The hydraulic expansion of a stainless steel tee is a forming process in which the branch pipe is expanded by axially compensating the metal material. In this process, a special hydraulic press is used to inject liquid into the tube blank with the same diameter as the tee, and the tube blank is squeezed by the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The liquid pressure increases as the volume of the tube decreases. When the pressure required to expand the stainless steel three-way 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 branch pipe, thereby expanding the branch pipe. Do it. .. The hydraulic bulging process of the stainless steel tee can be formed at one time, which improves the production efficiency. Increased the thickness of the shoulder wall of the main pipe and the stainless steel tee.
Classification: As the hydraulic expansion process of stainless steel tees requires a lot of equipment, it is currently mainly used to produce stainless steel tees with a standard wall thickness lower than DN400. Applicable molding materials are low carbon steel, low alloy steel and stainless steel, which have a relatively low tendency of cold work hardening, including some non-ferrous metal materials, such as copper, aluminum and titanium.
Precautions when opening stainless steel three-way pipe fittings: The extrusion deformation of stainless steel three-way pipe fittings belongs to tensile deformation. If ε is large, the neck at the end of the hole will shrink and be damaged. Therefore, avoiding cracks at the end of the hole is the main problem of extrusion, and it is the ultimate deformation of one extrusion. This sequence is mainly limited by the expansion rate of stainless steel data.
In the process of opening the stainless steel tee joint, please keep the following points in mind:
1. The stainless steel three-way joint ball valve is in the closed position. The ball valve is affected by the mechanical pressure of the valve stem, and the valve seat pressure is too tight.
2. Move the handwheel counterclockwise, the valve stem of the stainless steel three-way ball valve will reverse, and the angled plane at the bottom will cause the ball to come out of the valve seat.
3. The valve stem is still pulled out, and the guide pin is stained in the spiral groove of the valve stem, so the ball head will not be twisted due to friction.
4. Before reaching the full azimuth angle, pull the valve stem to the extreme azimuth angle, and the sphere is at the full azimuth angle.
Six major structural characteristics of stainless steel tee
1. Friction-free opening and closing: It completely solves the problem of traditional valves affecting the sealing due to mutual friction between the sealing surfaces;
2. Upper installation structure: The double valves installed in the pipeline can be directly inspected and repaired online, thereby effectively reducing equipment downtime and reducing costs. This kind of valve should usually be installed horizontally in the pipeline.
3. Single valve seat design: eliminates the problem of abnormal pressure increase in the valve cavity medium, thereby affecting the safety of use.
4. Low torque design: The specially designed valve can easily open and close the valve with a small handle;
5. Wedge-shaped sealing structure: The valve is sealed by the mechanical force provided by the valve stem, pressing the ball wedge on the valve seat, thereby weakening the tightening force of the valve. Affected by the change of pipeline pressure difference, the sealing performance can be reliably guaranteed under various working conditions.
6. Self-cleaning structure on the sealing surface: When the sphere is inclined from the valve seat, the fluid in the pipeline is 360 degrees along the sealing surface of the sphere. The uniform flow path not only eliminates the partial cleaning of the valve seat by the high-speed fluid, but also flushes the deposits on the sealing surface to achieve the purpose of self-cleaning.
