1.Cast Iron Manhole Cover Description :
A manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.
Applications: water supply and drainage, fire engineering, natural gas,
electricity and telecommunications, street lamp and outdoor illuminations.
Designs: based on EN124 standard and according to customer's drawing or samples.
Color: black, Grey, green, blue and Marble , etc.
Inspection: in-house or the third party as per customer's request.
2.Main Features of the Ductile Iron Manhole Cover:
Light weight
Compared with cast iron manhole cover, FRP manhole cover is 30% lighter.
Light weight allows more loading per vehicle, more convenient transportation and economical savings.
Allows a safer working condition, which single workers is enough for installation without risk of injury.
Long service life
Strong resistance of acid, alkali, weathering, anti corrosion of water, dust, manhole covers used for gas are well sealed which prevent poisonous gas leaking.
Temperature tolerance is at the range of -40°C-200°C.

5.FAQ:
We have organized several common questions for our clients，may help you sincerely：
Q. I’ve measured my clear opening size but none of your covers match it, can you offer anything?
A. It’s likely that your cover is quite old and in imperial measurements which are no longer manufactured. However, we can offer bespoke solutions with manhole covers made to the specification you require.
Q. The project I’m working on requires a manhole cover with a quality finish, what’s available?
A. Naturally, galvanised steel of black polypropylene aren’t always ideal, and so we offer brass or stainless steel edging, as well as complete stainless steel covers.
Q. Odours are coming through where I have installed my manhole cover, why?
A. Your cover must be sealed and locked, or neoprene sealed, so you would require a T-Range Cover, or if you require a solid top, a selection of the PC range (e.g. PC2BG3, PC6CG3, not PC2BG) are suitable.
- Q: What are the casting parts used to test shrinkage holes?
- 1. anatomy. It is easy to slack off by sawing and machining.
- Q: The casting defects of pores, trachoma how to repair?
- Airhole above 2mm recommended LT101 casting defect repair agent. If repair quality requirements, high availability LT111 iron repair agent, LT112 steel repair agent, LT113 aluminum repair agent, LT114 copper repair agent.
- Q: What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
- 3, weight: if reinforcement in products, casting weight is generally greater than the welding parts (the internal organizational structure and mode of production determines the mechanical properties of materials, so it determines the weight of the product), considering the cost of transportation, certain priority structure.
- Q: What is the reason for 304 stainless steel precision casting parts to be changed?
- Steel deformation control is one of the most common problems in the metal processing industry. Any process will occur. The casting is the largest deformation and the least fine. It is generally used to produce blank blanks
- Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
- Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
- Q: What kind of flaw detector is better for casting parts?
- If the casting is very small, can be used for fixed magnetic detection machines, of course with fixed magnetic powder the testing machine, the best first contact the manufacturers, because the fixed magnetic particle testing machine belongs to the non-standard equipment, according to the workpiece size, different shape, manufacturing daily inspection and measurement.
- Q: Which surface is coarser for cast iron or cast steel castings? Why?
- The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron. Roughness mainly depends on the surface roughness on the surface of the sand.
- Q: What are the general technical requirements for casting parts?
- What kind of casting do you want to know? Copper parts, iron pieces, aluminum pieces??? Their casting conditions are different.
- Q: Can the casting part be phosphating with the phosphating solution of the pickling board?
- If it is Phosphating for painting, it is not necessary, because the surface of the casting is rough and can be firmly bonded with the paint film.
- Q: In the design of casting steps and precautions, for casting design, we have what experience?.
- (3) to prevent generating white grey cast iron, in addition to taking measures from the process, must make the wall thickness is not too thin (some sources indicate that the corner wall thickness above 15mm, metal type casting must be in the corner, for Aluminum Alloy, magnesium alloy casting casting casting Create fillet should not be less than 3-4m, for casting round cast iron, copper alloy mould casting can see table 1.1-32 selection; (5) because of the metal and the core without let, for the convenience of the casting is taken out and the draw out type, slope casting casting should be suitably large than sand casting metal casting. General 30%-50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction and metal surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal castings the type should be given greater inclination, all kinds of metal type alloy casting casting casting.
