{dede:global.cfg_gsname/} | Updated: 2020-10-21 07:23:21
Composite manhole cover, composite frame and waterproof sealing ring bearing waterproof and explosion-proof manhole cover
The product has the characteristics of sealing, flame retardant, anti-static, anti-corrosion, chemical solvent resistance, acid and alkali resistance. It is specially used in the petroleum, petrochemical industry and gas stations all over the country.
Special conductive waterproof circular composite manhole cover circular 900 series is composed of composite manhole cover, composite frame and waterproof sealing ring. The effective opening diameter of frame is 900mm, which is commonly used in manhole manhole in vehicle driving area of gas station front yard.
The special conductive waterproof circular composite manhole cover for oil station is light in weight. On the premise of the same size and bearing capacity, the weight of conductive waterproof composite manhole cover is only 10% of that of cast iron manhole cover, which greatly reduces the daily opening workload and labor intensity after the manhole cover is installed (such as the oil metering work of oil filling station).
Conducting static electricity: eliminate the potential risk of electric spark caused by static friction in gas filling station.
composite manhole cover
Corrosion resistance: the characteristics of FRP composite material endow the underground closed waterproof well system with high corrosion resistance. It can be used for a long time even in the corrosive environment of different acids, alkalis, salts and organic solvents (oil, gas, etc.), which is suitable for the actual use environment of gas stations.
Aging resistance and long service life: it is made up of high quality matrix resin and anti-aging compound additives. The product has a durable anti-aging property, which can resist creep decay. It can maintain long surface gloss and continuous high strength, and its service life is more than 30 years.
