DN600 ductile iron Manhole Cover

?The spheroidal manhole cover is a kind of spheroidal graphite cast iron. The spheroidal graphite cast spheroidal graphite is spheroidized and inoculated to effectively improve the mechanical properties of the cast iron, especially the plasticity and toughness, thereby obtaining higher strength than the carbon steel. Ductile iron is a kind of high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its excellent performance and has been successfully used for casting some complex forces, strength, toughness and wear resistance. Parts with higher requirements. Ductile iron has rapidly developed into a widely used cast iron material after gray cast iron. The so-called “iron-based steel” mainly refers to ductile iron.

Application
(1) Electric power pipeline well; Post, telecommunication, communication pipeline well;
(2) Street lamp well, fire control well, all kinds of valve well;
(3) City water, drainage pipeline well; Heat supplied, gas well;
(4) Anti-corrosion project, open ditch; It as well as can be made according to customers requirements.

1. Against theft — Composite Manhole Cover with shockproof rubber sealing is non-metallic, non-conductive and non-sparking, has no value of recycling, completely solving the theft problems.

?

2. High load capacity —Its main components are fiberglass and unsaturated resin. oad capacity are A15, B125, C250, D400, E600.

?

3. Free design—Such as Color, Logo, Panel, Load and Dimension can be designed according to the requirements of customer.

?

4. Long life —Minimum lifespan is 30 years free of maintenance.

?

5. Well sealed —It can be installed hermetically, and effectively prevent poisonous gases leaking out from cesspool. and no noise pollution or rebound.

?

6. Good wear and corrosion resistance —It will never rust because it has good wear and corrosion resistance.

?

7. High and low temperature resistance —Excellent insulator ( from-40°C~200°C)

?

8. Lighter weight and more competitive price— the weight of composite manhole cover especially SMC manhole cover is lighter. The composite manhole cover is more convenient to transport, install and repair.
