Huajian's stamping bed board refers to a metal plate with holes in various shapes on its surface. The stamping plate is made of steel plates of various materials by stamping, shearing, stretching or punching. The strip-shaped bed board is formed by stretching or differentiating steel plates of various materials in proportion.
I estimate that the beds of medical beds are made of these materials: stainless steel plates, aluminum plates, low-carbon steel plates, aluminum-magnesium alloy plates, copper plates, nickel plates and so on. Weaving and characteristics: punching and extending; Divided into: punching mesh, steel mesh, aluminum mesh, sieve plate, punching plate, horn mesh, etc.
The bed board of medical bed has the performance characteristics of perforated bed board:
1, the multi-layer sand control filter sleeve has high sand control performance, which can better block formation sand particles and meet the needs of underground sand control.
2. Uniform filter holes, high permeability and anti-clogging performance.
3. Large filtering area, small flow resistance and high oil yield.
4. Stainless steel has excellent corrosion resistance, which can resist acid, alkali and salt corrosion, and can meet the special requirements of oil wells, and the cracks will not gradually become larger due to corrosion.
5. The multi-layer structure welded together can make the filter hole stable and have strong deformation resistance. The outer protective sleeve can also be spiral welded.
The advantages of strip bed board and perforated bed board are different, and there are similarities on them.
