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. -
How to do well the pressure test of nodular cast iron manhole cover [2023-08-25] The main use of manhole covers is often universal, and the reason why the actual effect is very great should be attributed to its manufacturing process. Then, in order to better improve the quality of goods, it is a very important part to constantly improve the security risks of technical goods. The pig iron well cover can be normally delivered for use only after the pressure test is completed: -
How to Apply the Drainage of Ductile Iron Well Cover [2023-08-18] At present, most of the drain pipe manhole covers used in municipal engineering are forged from ductile iron, and their structures include the support frame, the well ring set on the upper end of the support frame, and the manhole cover installed in the well ring. For better anti-theft, the well cover and well ring are connected according to screws, and the wall top of the well cover is provided with a ground sliding convex to prevent the ground from sliding. At the same time, in order to better avoid the abnormal noise caused by the upward vibration of the manhole cover due to the negative pressure at the rear end of the car when the car passes, a stop is set in the inner cavity of the well circle. The ductile hanging wall shall be fixed at the bottom of the manhole cover. When the manhole cover falls, the ductile hanging wall and the block shall be installed on the manhole cover in coordination. -
How to Clean Chongqing Composite Well Cover [2023-08-11] Composite well covers are often used in various projects and have many advantages. So, how to clean it during daily use? Steel castings used for composite well covers are usually made in places with more dust, and the dust in the air often falls on the equipment surface. It can be removed with water or alkaline solution. However, sticky dirt needs to be cleaned with high-pressure water or steam. -
Quality distinguishing skill of nodular cast iron manhole cover [2023-08-04] Ductile iron manhole covers are widely used at present. The manhole cover has high tensile strength and can not be broken by a hammer. Its modeling design can be changed according to customer requirements. In the future, gray black asphalt will be sprayed to make the products bright, clean, tidy, resistant to air oxidation and corrosion. Select the integrated design scheme of well cover and well seat, and install the hardware lock on the rotary table. The nodular cast iron manhole cover adopts a new anti-theft scheme with a design scheme, and the lock and key are made of high toughness, rust proof red copper to prevent the lock from rusting in the whole process of daily application, making the manhole cover unable to open. Nodular cast iron manhole cover has no noise and meets environmental protection requirements. -
Transportation Method of Ductile Iron Well Cover [2023-07-28] Ductile iron manhole covers bring convenience to everyone's manufacturing and life. The existence of manhole covers can be seen in the streets. However, if a customer buys a manhole cover, the manufacturer also needs to pay attention to many key issues on the transportation manhole cover. If damage is caused on the shaking road, it will cause great damage to the ductile iron manhole cover. Therefore, proper transportation method can be regarded as good maintenance for nodular cast iron manhole cover. -
How to prevent theft of nodular cast iron manhole cover [2023-07-21] Many news reports said that in a street community, passers-by almost fell into the sewer, because the ductile iron manhole cover was stolen, it was not immediately restored. Anti theft measures are taken for the manhole cover. What is the actual method? -
What is the difference between the composite manhole cover and other manhole covers? [2023-07-14] With the continuous development of modern urban construction, the traditional manhole cover has gradually failed to meet the needs of work, so the new composite manhole cover has gradually become the mainstream with its good appearance and performance. Its mainstream is that it has many advantages compared with the traditional manhole cover. -
What causes the sinking of nodular cast iron manhole cover in use? [2023-07-07] The application of nodular cast iron manhole covers plays a vital role in urban municipal administration. The appearance of many ductile iron manhole covers with different models and specifications has brought great convenience to everyone's daily life. However, after a period of use of ductile iron manhole covers, there will be a problem, that is, the sinking problem in application. According to this question, let me explain it to you in detail. -
Why is the ductile iron manhole cover designed to be round? [2023-06-30] In our daily life, manhole covers can be seen frequently. When designing the manhole cover, the manhole cover manufacturer also spent a lot of time on its design. The occurrence of nodular cast iron manhole covers has basically improved the spherical high-purity graphite of traditional pig iron manhole covers, that is, the nodular cast iron manhole covers that promote production have improved their physical properties and ductility on the original characteristics, that is, the nodular cast iron manhole covers that are manufactured. -
Correct derusting method of nodular cast iron manhole cover [2023-06-23] Generally speaking, nodular cast iron manhole covers rarely rust, but once this happens, everyone needs to derust them, so how should we derust them? This article will give you a simple explanation.
