Product Description:

 

Manhole Cover Class C250

 

We manufacture top quality Manhole Cover made from cast iron, cast steel and stainless steel. We take pride to introduce ourselves as the leading manufacturer and professional supplier of various Ductile Iron Manhole covers and gully grating in China with total annual capacity 50,000 MT. We are identified as one of the celebrated Manhole Cover Suppliers in China.

 

Class C250 (group 3 according to EN124)

 

The access covers and grates of this class are capable of withstanding a 250kN (~25 tonnes) test load.

 

Usage of Ductile Iron Manhole Cover C250 :

Pedestrians, Pedal Cyclists

 

Features of  Ductile Iron Manhole Cover C250 :

1. High load rating and strength

v Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery.

v Less noise and lower vibration transmissions.

 

2. Against theft and safety options

v Zero theft value, reducing potential accident and further maintenance cost caused by thieves.

v Surface anti-slip thread guarantees safe road condition even in extreme weather.

v Locks are available as an option molded into the cover to improve security rate.

v Non-electricity conduction and non-heat conduction.

 

3. Lightweight 

v Compared with cast iron manhole covers, composited covers are 50% lighter.

v Lightweight allows more loading per vehicle, more convenient transportation and economical saving.

v Allows a safer working condition, which a SINGLE worker is enough when installation without risk of injury.

 

4. Durable service life.

v More than 30 years service life without crack and color fading, comparing to 5 years of cast iron.

v Anti corrosion,water, dust and pets tight, well sealed prevent poisonous gas leaking out.

v Without displacement, freely radio signal passing.

v Higher and lower temperature tolerance with the range -40°C-200°C.

v Wear indicators available when thread depth is in a danger value.

 

5. Free design

v Much more clear resolution ratio of surface design than cast iron or BMC.

 

6. Carbon footprint saving and environmental care.

v Lower embedded energy carbon emission and during manufacturing process than cast iron covers.

Q:What are the requirements for casting steel castings?
4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface
Q:How to distinguish the forging parts and casting parts accurately
Distinguish from scopeShanghai Zhejiang forest auto parts experts pointed out that the forging process can eliminate cast loose, metal welding holes, so an important part of high load working conditions, severe machinery, in addition to relatively simple shapes can be rolled plates, profiles or welded parts, the forging process. Because of its low cost and good economy, casting parts processing is widely applied and belongs to the basic process of modern machine building industry.
Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?
Proofing? In the casting industry is not called proofing, proofing is generally used in the printing industry, that is, according to the customer's drawings or samples, to do a first piece, to provide customers with the inspection process to meet their requirements;In the foundry industry, providing prototypes is sometimes difficult:1, customers if the provision of mold, it would be best, at this time, sample costs are very low, and almost the same as your regular products;2, the customer does not provide the mold, but in business relationships, your factory and not very sure must take this one, it requires your leadership decision-making, is free or low cost, or by a strict process offer (of course sample);3, not all of the casting process to provide samples are difficult, like lost foam can directly make a white NC prototype, and then assembled pouring, this is her unique advantages, first cost less than the opening process and so on;If you don't understand, you can continue to question me
Q:After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.
The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool
Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?
This is too muchYou do not have a specific list of statistics, but there are many foundries in china!Moreover, car prices are unlikely to be ordered in the local factories!
Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
The aim is to make the grain fine and distribute the carbide evenly. The difference between normalizing and annealing is that normalizing cooling rate is slightly faster than annealing cooling rate, so normalizing structure is finer than annealing structure, and its mechanical properties are also improved. In addition, normalizing furnace cooling does not occupy equipment and has higher productivity. Therefore, normalizing may be used instead of annealing as much as possible. The main application areas of normalizing are as follows: for low carbon steel, after normalizing, the hardness is slightly higher than that of annealing, and the toughness is better. It can be used as the pretreatment of cutting. Used for medium carbon steel, instead of quenching and tempering, as the final heat treatment, or as an induction heating method before surface hardening. Used for tool steel, bearing steel, carburizing steel, etc., it can eliminate or restrain the formation of network carbide, so as to obtain the good organization of spheroidizing annealing. For cast steel, the microstructure can be refined and the machinability can be improved. Used for large forgings, which can be used as final heat treatment, so as to avoid larger cracking tendency during quenching.
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over
Q:Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
There are various casting stresses after casting, which can be divided into two kinds: thermal stress and shrinkage stress. In a long time placed in the atmosphere, called aging treatment.Aging treatment is an effective measure to eliminate casting stress. Aging is divided into natural aging, thermal aging and resonance aging.1, the so-called natural aging, the casting is placed in the open field for more than half a year, so that the internal stress relief.
Q:What is the casting material?
Gray iron, carbon steel, low alloy steel, ductile iron, stainless steel, Aluminum Alloy can all be cast out
Q:What are the casting parts tested?
The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
MAXCOVER,rich on the resources for castings and the convenient transportation, is specialized in manufacturing and exporting gray iron & ductile iron anti-stealing manhole covers with frames, grates, pipe fittings and etc. our enterprise covers an area of 15000 square meters .we re-passed the ISO9001:2008 International Quality System Authentication in Aug,2010,adopt the international standard and established the system of the quality assurance arising according to ISO9001 quality level.
