Invisible stainless steel manhole cover
The role of invisible stainless steel manhole cover is to cover the defenses on the road or in the deep well in the home to prevent people or things from falling down. Generally divided into circular and square, in the urban road management, circular is generally used, because the round stainless steel manhole cover is not easy to tilt, can better protect the safety of pedestrians and vehicles. The use of circular is mainly considered that the diameter of the circular manhole cover through the center of each circle is the same, so if the manhole cover is rolled up by the passing vehicle, because the diameter will be slightly larger than the wellhead below, Wide, the manhole cover will not fall into the wellhead.
If a square stainless steel manhole cover is used, since the square diagonal line is significantly longer than each side length, when such a manhole cover is rolled up, it is easy to fall into the well along the diagonal direction of the wellhead, causing hidden safety hazards. If the wellhead is made round or significantly smaller than the manhole cover, the square manhole cover will not fall into the well. This involves the issue of maximum utilization and savings of materials. The use of a wellhead depends on the size of the wellhead. If you have to install a square manhole cover that is much larger than the wellhead, then the use and practical value of the material is naturally more effective than directly using a round manhole cover. Ensure the safety of the wellhead.

What are the advantages of invisible stainless steel manhole covers?
I. Anti-theft: Compared with other materials, stainless steel manhole covers have higher firmness, smaller joint gaps, ordinary tools are difficult to pry open, and the anti-theft performance is strong.
2. Safety: The manhole cover should not only prevent theft, but also take responsibility for the safety of the pipeline construction personnel. Because of the use of steel bars, the stainless steel manhole cover does not smash even if it reaches a destructive load, preventing all aspects of damage caused by falling.
3. High precision: The stainless steel manhole cover is molded, and the gap between the cover and the seat joint is small, which overcomes the problem of "running, jumping and ringing" of the original manhole cover, and greatly improves the road traffic performance and driving comfort.
4. Convenient and beautiful: The stainless steel manhole cover is only two thirds of the cast iron manhole cover , which brings great convenience to installation and inspection. Invisible manhole covers can also be used, so that the overall appearance is not damaged. It can be classified and colored according to industry sectors, which is convenient for classification management.
V. Environmental protection: The manhole cover is open-air all the year round, which requires high corrosion resistance. The stainless steel manhole cover is not only moisture-proof, acid and alkali resistant, but also anti-aging, and has a long service life.
