Product Description:

 

Product Description:

 

 

Specification of Ductile Gully Grates B125:

 

Class B125: EN124

The access covers and grates of this class are capable of withstanding a 400KN(-40 tonnes) test load

 

 

Use:

 

carriage ways, hard shoulders and pedestrian areas where cars and lorries have access.

 

 

Features of Ductile Gully Grates B125:

 

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.

 

 

Packaging:

 

Metal band, plastic, wooden pallet. As per customers' requirements

Q:In theory, which is more expensive, forging parts or casting parts?
It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high
Q:Why should pig iron be used in casting?
Cast iron is generally called pig iron, but casting is not merely iron casting.For example, injection molding, die casting, and so on, in fact, cast iron, cast steel, cast aluminum, plastic and so on, can be used in the form of casting processing molding
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:How to cast iron and wrought iron collocation
2, listen: Pig beating sound boring, wrought iron beating sound loud.
Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
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 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:What's the effect of casting copper?
Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.
Q:For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
According to the grade of the parts, according to the relevant standards, the regular drawings will be noted in the technical requirements of the parts.
Q:When there is no flaw detection for large casting parts, is there any crack inside?
Cracks are considered serious levels of defects and should be repaired
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.
