 In central heating systems in cold cities, heating manhole covers are used to cover the wellheads of heating pipes. It can facilitate the heating company to carry out daily inspection, maintenance and emergency repair work of the heating pipeline. During the winter heating period, entering the pipeline through the manhole cover can deal with problems such as leakage and blockage of the pipeline in time, ensure the normal transmission of heat energy, and allow residents to stay warm in winter.

Advantage and Feature

High strength and load-bearing capacity
Cast iron manhole cover has high compression, bending resistance, impact strength and toughness, can withstand the repeated crushing of transport vehicles, and is not easy to crush or damage after long-term use, which can effectively prevent the "urban black hole" accident caused by damage to the manhole cover and ensure the safety of the transportation process.
Different types of cast iron manhole covers can meet different load requirements, such as the manhole cover load class specified in the European standard EN124, from 15kN for pedestrians and bicycles only, to 900kN for large tire load lanes such as docks, airport runways, etc., which can be selected according to the specific needs of the transportation site.
Strong stability
Due to the equal distance from the center to the circumference of the circular cast iron manhole cover, no matter how the vehicle rolls it, the manhole cover is not easy to tilt, shift or fall into the wellhead, which can better cooperate with the wellhead and maintain a stable coverage state, so as to ensure the safety of transport vehicles and pedestrians
