1150*1150mm B125 Integrated Management Manhole Cover with Remote Control and Multi-function

Underground comprehensive pipe corridors are public tunnels built underground in cities for the centralized laying of municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heat, and gas.

Feilong New Materials uses new technologies to develop new integrated pipe gallery manhole covers. It is a special mechanical manhole cover for the escape hatch of the underground comprehensive pipe gallery project. The product is made of ductile iron casting or steel plate welding, which is safe, strong, beautiful and high in strength.

Pipe gallery manhole covers are divided into electric push type, electro-hydraulic type, hydraulic type and explosion-proof type according to the opening method; there are two sizes: F1000/1150 (B125) and Φ1000/1220 (B125).

Advantages of Ductile Cast Iron

-High Strength and Durability

Compared to grey cast iron, ductile iron has higher tensile strength, yield strength, and elongation, making it suitable for heavy-duty applications requiring stress resistance.

-Good Machinability

Ductile cast iron is more accessible to machines than steel or aluminium due to its lower hardness and better lubrication properties. This can save time and cost in the production process.

-Good Casting Properties

Ductile iron has excellent fluidity, filling complex moulds with intricate details and thin sections. It can also be cast in larger sizes without porosity or cracking.

-Corrosion Resistance

Due to its high carbon content and protective graphite layer, ductile iron is resistant to corrosion from many chemicals, water, and atmospheric conditions. It is often used in marine and offshore applications.

The applications of ductile iron manhole covers include but are not limited to municipal construction, water project like sewerage, water supply, footway,  rainwater, gas, heat, fire, telecommunication, carriageway, etc.
