Round And Square Ductile Iron Cast Iron Manhole Cover
Production Description
● Strong bearing capacity and not easy to deform.
● High impact toughness and high strength
● Good mechanical properties, good comprehensive performance
● The surface is smooth and does not affect people’s daily life
● Easy to install.
● Good toughness. The impact value of medium carbon steel is very fine, more than 10 times that of gray cast iron.
● Strong corrosion resistance. In the water spray corrosion test, the corrosion amount in 90 days is only 1/40 of the steel pipe and 1/10 of the gray iron pipe. The service life is twice that of gray iron pipes and five times that of ordinary steel pipes.
● Good plasticity. Elongation ≥ 7/100, similar to high carbon steel, while gray cast iron material has zero elongation.
● 4. High strength. The strength of ductile iron is comparable to that of cast steel. Ductile iron has a higher yield strength of at least 40k, while cast steel has a yield strength of only 36k. In most municipal applications, such as water, salt water, steam, etc., the corrosion and oxidation resistance of ductile iron exceeds that of cast steel.
● Better anti-theft and safety performance: The tensile strength and pressure resistance of ductile iron manhole cover tweezers are similar to those of steel, so they are called cast steel. Compared with the traditional gray cast iron, its elongation is greatly improved, the toughness is good, and it is not easy to break. It has better anti-theft performance than ordinary cast iron manhole covers, and the overall performance is much better than ordinary cast iron manhole covers.
● No noise: Due to the patented structure can prevent noise, when the manhole cover passes through, there will be no sound, no longer disturbing people. There is no doubt that the quality of ductile iron manhole covers is far superior to other manhole covers.
Application Area
The main applications are: municipal roads, highways, communications, electricity, water conservancy, communities, schools. All kinds of parks, for sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines
