What Requirements Should Be Considered When Using Chengdu Stainless Steel Decorative Manhole Covers?

1. Marking: If the manhole cover is for sewage drainage pipes, the surface should have a "sewage" mark; if it is for rainwater drainage pipes, the surface should have a "rain" mark. The two should be distinguished, and the marks should be clear and easy to check.

2. Inner and outer cover settings: Unless otherwise specified, if a metal manhole cover of a drainage inspection well has a protective cover seat, an inner cover should also be installed.

3. Internal settings of the manhole cover: For stainless steel manhole covers, the selection should be determined according to factors such as the sewage pipe medium, the wellbore diameter and the well pipe fittings.
