Selection knowledge of heavy ductile iron manhole cover [2023-11-17] Heavy ductile iron manhole cover is a kind of forged iron products. According to gray cast iron and manufacturing, forged cast iron can obtain spherical forged petroleum coke. The professional knowledge of fluctuations in the purchase of ductile iron manhole covers has improved the technological properties of cast iron. The plastic deformation and plasticity of pig iron plastic art manhole cover are greatly improved, thus obtaining higher tensile strength than that of carbon steel. Forged cast iron is a kind of high wear-resistant cast iron raw material developed in the 1950s. Its comprehensive properties are close to steel. According to its excellent characteristics, the expertise of the purchase fluctuation of ductile iron manhole covers has been successfully applied to forging some processes with complex supports. -
Process Characteristics of Heavy Ductile Iron Well Cover Technology [2023-11-10] With the continuous improvement of the utilization rate of heavy nodular cast iron manhole covers, their product quality is also getting higher and higher. Because of their characteristics and advantages, they have been widely used. In order to better use them, let's take a look at the technical processing characteristics of nodular cast iron manhole covers. -
How to install the ductile iron manhole cover correctly? [2023-11-03] How to correctly install ductile iron manhole cover? In order to better ensure the normal use of nodular cast iron manhole covers, attention should be paid to the installation quality to ensure that the specifications and models are accurate, the installation is firm, the opening is convenient and fast, and the surface is clean and unique. According to the technical standards for inspection of pig iron well covers, what are the special advantages of cast iron ductile well covers? Nodular cast iron manhole cover manufacturers. -
Performance Characteristics of Heavy Ductile Iron Well Cover [2023-10-27] Performance Characteristics of Heavy Ductile Iron Well Cover 1. High compressive strength: diamond shaped magnesium inspection, high compressive strength, high bending strength, high impact compressive strength, and strong ductility. Heavy nodular cast iron manhole covers, nodular cast iron manhole covers, and manufacturers of nodular cast iron manhole covers cannot crush and destroy manhole covers after long-term use. Ductile cast iron manhole covers can avoid the occurrence of "urban black hole" safety accidents. -
What are the performance and manufacturing process of nodular cast iron manhole cover? [2023-10-20] What are the properties and manufacturing steps of ductile iron manhole covers? Here is an introduction: Gray iron castings are similar to those already used in all key industrial sectors. The unit specifies high compressive strength, plastic deformation, ductility, severe heat resistance, impact resistance of mechanical equipment, heat resistance or ultra-low temperature, specification stability, etc. -
Difference between Ductile Iron Well Cover and Gray Iron Well Cover [2023-10-13] Well covers are widely used. Many people can't tell the difference between ductile iron well covers and gray iron well covers. Here is an introduction. Ductile iron manhole covers are more elegant. The commonly used materials for the new type of nodular cast iron manhole covers are the best evaluated gray cast iron, coke and nodulizer gray cast iron grades of professional designated manufacturers, and the operation is within the range of 1-2 grades. The beautiful color of the surface is close to the whole surface, and the concrete well ring is not exposed. Under the standard of the flatness of the manhole, the manhole cover is integrated into the ground and the road is integrated to achieve the cleaning result. -
Difference between nodular cast iron anti settlement well cover and ordinary well cover [2023-10-06] When we drive to check the manhole cover, we often make a "bang" sound, which is caused by the abnormal noise caused by the settlement and fluctuation of the manhole cover. On the roads of many big cities, or mainly with ordinary cast iron well covers, they are damaged by the basic principle structure of the well cover itself and the addition of processing technology. In addition, if they are rolled by super heavy vehicles for a long time, they tend to move down, crack around the well and other diseases and pests. However, the new anti settlement well cover has a special structure, wider diameter than the ordinary well cover, larger total installation area, and has the advantages of anti settlement, anti-theft, anti loosening, and anti abnormal noise. -
What are the reasons and solutions for the rust of nodular cast iron manhole covers? [2023-09-29] The longer the service time of nodular cast iron manhole covers is, the more problems may occur. Therefore, to solve this problem, we need to first know how to solve it and how to solve it. Let's discuss with you a problem that is likely to be encountered in the future. What should we do if the goods rust? -
What is the effect of different shapes of cast iron manhole covers on their application? [2023-09-22] Well covers are used to cover roads and deep wells to prevent people and objects from exploding. Generally, circle is selected. It can be used for street greening, sidewalks, motorways, ports, street communities, etc. If there is no road, it is likely to bring changes to daily life. Wide cast iron manhole covers are usually round and square. So, what harm does different appearances do to applications? -
Conditions required for processing of nodular cast iron manhole covers [2023-09-15] Nodular cast iron manhole covers occur more and more frequently in daily life, and are also highly valued by everyone. Do you know what production and processing standards should be paid attention to during the production and processing of ductile iron manhole covers? Here's how: -
Reason for Designing Pattern on Ductile Iron Well Cover [2023-09-08] In daily life, people will notice that there are various patterns on the surface of nodular cast iron manhole covers. I don't know why the manufacturer did this. Most people think it is beautiful. Actually not. Let's briefly introduce why the design pattern: -
Common problems in construction of nodular cast iron manhole cover [2023-09-01] In the whole construction process of nodular cast iron manhole cover, if the construction is improper, it is easy to have some problems in the whole construction process. If this problem is not solved properly, it is likely to endanger the middle and later application of the manhole cover, thus reducing the service life of the ductile iron manhole cover and bringing great inconvenience to everyone. In order to better prevent this situation, the following details several problems that are easy to occur during the construction of nodular cast iron manhole covers. Let's take a look.
