- Place of Origin: HENAN
- Brand Name:
- Model Number: 1
technical parameter
Technical parameters test load: heavy 400KN, universal 250KN, light 125KN
Bending strength: average 22MPa impact strength: average 10J/m2
Water absorption: 1%
Acid resistance: sample in 20%
Immersion in sulfuric acid solution 48H
No corrosion on the surface, quality loss 1%
Performance characteristics
1, high strength: MAGNESITE examination has high compressive strength, flexural strength and impact toughness. After long-term use of the product will not appear manhole cover is crushed and damaged phenomenon, can completely eliminate the occurrence of "city" of black hole accident.
2, the appearance of the United States: MAGNESITE manhole cover surface pattern design is exquisite, bright color adjustable, beautify the city environment.
3, easy to use, light weight: the weight of the product is only about 1/3 of the cast iron, convenient transportation, installation, repair, greatly reducing the labor intensity.
4, anti-theft: MAGNESITE manhole cover no recycling value, natural security; according to customer needs and is provided with a locking structure, well property theft.
5, strong weatherability: MAGNESITE manhole cover by scientific formula and advanced technology, improve the technology and equipment make the product which can be normally used in the - 50 DEG to 300 DEG C environment.
6, acid and alkali resistance, corrosion resistance, abrasion resistance, rolling resistance, long service life.
Two categories
According to the material to distinguish
Can be divided into 4 categories
A. metal cover: cast iron, ductile iron, bronze covers etc.;
B. high strength steel fiber cement concrete cover (cement composite material);
C. regenerated resin covers (recycled resin composites);
D. polymer composite material manhole cover etc..
among
The composite material manhole cover is divided into inorganic and organic composite covers two kinds of composite covers.
Steel fiber concrete manhole cover according to the bearing capacity is divided into a, B, C, D four:
A steel fiber concrete manhole cover, such as roads and venues for airport construction.
B grade steel fibre concrete manhole cover for motor vehicle parking, city roads and highways and parking lot.
C grade steel fibre concrete manhole cover, roads and sidewalks for residential areas in the slow lane.
D grade steel fibre concrete manhole cover, for green belt and motor vehicles can not travel, parking lane and site.
Distinguish by shape
Generally divided into circular and square.
In urban road, the general use of circular and because round manhole cover is not easy to incline, can better protect the pedestrian and vehicle safety.
In the countryside and cable wells, the general use of square, so as to better prevent the rain and other liquids into the.
