Anti-Settling Cast Iron Gully Grate For Rain
Characteristics
The anti-settling grate is made of ductile iron QT500-7, and the raw materials should comply with the provisions of GB1348. There are various styles of manhole covers, and they are selected according to the design. The bearing capacity of the rainwater grate is not less than 140KN. The rainwater grate should be made flat and smooth with the surface of the support, and there should be no cracks and defects such as cold insulation and shrinkage that affect the performance of the rainwater grate, and no repair welding. The grate and the well ring can be connected by a pin (or other forms), and the flip angle of the grate is not less than 120°. The anti-corrosion method of the grate and the well ring is: asphalt varnish once.
1. Beautiful appearance: simple lines, silver appearance, modern trend.
2. Drainage: The leakage area is 83.3%, more than twice that of cast iron.
3. Hot-dip galvanizing: strong anti-rust ability, maintenance-free and replacement-free.
4. Anti-theft design: The cover and the frame are connected by hinges, which is anti-theft, easy to open.
5. Save investment: When the span is large and the load is heavy, it is cheaper than cast iron and saves the cost of replacement in case of theft or crushing.
6. High strength: The strength and toughness are much higher than cast iron, and it can be used in large span and heavy load environments such as docks and airports.
7. Many specifications: meet the needs of different environments, loads, spans, sizes and shapes.
Features
1. The flange surface of the support transfers the load to the pavement structure layer to avoid direct pressure on the well body, greatly reducing the possibility of sinking.
2. The flange surface of the support effectively protects the surrounding asphalt surface layer, is tightly combined with the pavement, and is not easy to cause water accumulation.
3. Use a roller to roll the manhole cover and asphalt together. Mechanized construction ensures that the manhole cover and the pavement are consistent in elevation and flat and compact. The manhole cover is tightly combined with the surrounding pavement, effectively preventing the pavement around the manhole cover from loosening, breaking, and damage.
Cleaning of the surface of the anti-sedimentation grate.
Manufacturing Process
Material Preparation: High-quality pig iron and scrap iron are melted together, with magnesium added to create a ductile iron alloy.
Casting: The molten iron is poured into molds to form the basic shape of the manhole cover. Sand casting is a common method due to its precision and efficiency.
Heat Treatment: The cast pieces are treated with heat to improve strength and flexibility.
Surface Coating: Anti-corrosive coatings are applied to ensure longevity in various environments.
Quality Control: Each cover undergoes rigorous testing for load-bearing capacity, tensile strength, and dimensional accuracy
