How to choose a suitable galvanized blind plate?
The key to choosing the right galvanized blind plate is the size, material, sealing performance and price. Ensure that the blind plate is perfectly matched to the hole, and has corrosion resistance, durability and good sealing performance.

Definition of pipeline
Pipes are devices used to transport gases, liquids or fluids with solid particles, which are connected by pipes, pipe couplings and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high pressure to the low pressure of the pipeline, and can also be transported by the pressure or gravity of the fluid itself. Pipelines are widely used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

The production process of the size head
Production of Seamless Head The reducer (reducer) is a kind of pipe fitting for pipe diameter. The commonly used forming process is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing, and stamping forming can also be used for certain specifications of reducers. Diameter reduction/expansion forming The shrinkage forming process of the large and small head is to put the tube blank with the same diameter as the big end of the large and small head into the forming mold, and the metal moves along the mold cavity and shrinks and forms by pressing along the axial direction of the tube blank. According to the size of the reducer, it is divided into one-time press forming or multiple press forming. stamping forming In addition to the use of steel pipe as raw material to produce the size of the head, the size of part of the size of the head can also be used steel plate stamping forming process for production. The shape of the die used for stretching is designed with reference to the size of the inner surface of the size head, and the blanking steel plate is stamped and stretched with the die.
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
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.
