In our daily life, we can use Shandong ductile iron well covers everywhere。 Do you know why they are widely used? Now Jinan Wanshun Casting Co。, Ltd。 will show you where they are widely used!
1。 Power supply engineering: it is used for power supply cable, telecommunication engineering, telephone, communication cable pipeline, which is also the power well cover and communication well cover we often see。
2. Gas engineering: Gas Engineering, natural gas pipeline, etc. are the gas well covers we often see.
3。 Drainage works: used for rainwater and sewage pipelines, as the cover of sewage well, rainwater well and drainage well。
4. Landscape engineering: supporting comprehensive pipelines are the stainless steel well covers, invisible well covers and caopun well covers that we often see.
5。 Heat supply project: heat supply pipeline is also the heat well cover and gas well cover that we often see。
6. Water supply engineering: it is used for tap water, fire fighting engineering, water meter box cover, etc., which is also the tap water well cover, fire well cover and water meter well cover we often see.
1。 Good patience。 The impact value of nodular graphite cast iron manhole cover and medium carbon steel are detailed, which are more than 10 times of gray iron data。
2. 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. Its service life is twice that of grey iron pipe and five times that of ordinary steel pipe.
3。 Good plasticity。 Elongation ≥ 7%, similar to that of high carbon steel, while the elongation of gray iron data is zero。
4. High strength. The tensile strength, yield strength and low carbon steel are the same, which are three times of gray iron data.
5. Beautiful appearance: simple lines, silver surface, modern trend.
6. Best drainage: the leakage area is 83. 3%, more than twice that of cast iron.
7。 Hot dip galvanizing: strong rust resistance, no protection and replacement。
8。 Anti theft design: the cover and the frame are hinged, anti-theft, safe and convenient to open。
9. Saving investment: in case of large span and heavy load, the price is lower than that of cast iron and the cost of theft or crushing replacement is saved.
10. High strength: the strength and endurance are much higher than that of cast iron, which can be used in long-span and heavy load environments such as docks and airports.
11. Many standards: meet the requirements of different environments, loads, spans, sizes and shapes
The above is the introduction of Jinan Wanshun Casting Co., Ltd. to the use direction of nodular cast iron manhole cover. I hope to help you. For more information, please click http://www.kpp647.com
